Mahmud
Aboagella Ali Rahuma
This investigation was carried out at Plant Production Department Laboratories, Faculty of Agriculture (Saba-Basha), Alexandria University, Egypt to study the impact of storage period and package material on growth and some chemical contents of Giza 168 and Sids 12 grain wheat cultivars using split-split plot design. The studied traits, except infestation percent, were significantly decreased with increasing storage period till six months. The lowest germination (65.41%), shortest roots and shoots (5.45 and 3.39 cm), lightest shoot weight (0.030 g) and highest infestation percent (25.25%) resulted from stored grains for six months (at November). Stored grains till November, also showed the lowest 100-grain weight (2.33 g), protein, ash and moisture content (6.81, 1.03 and 8.82%), respectively. Giza 168 cultivar significantly surpassed Sids 12 in all the studied traits except root length. Sealed Sids 12 grains in black polyethylene bags decreased germination percent, shoot dry weight, 100-grain weight, protein and ash grain content, however it showed the highest insect infestation percent. Sids 12 bread wheat cultivar, generally, was more affected with increasing storage period than Giza 168 cultivar.

The Present study was initiated for controllingthe American foulbrood (AFB) disease of honey bee colonies in six selected apiaries at El-Beheira and two apiaries at Kafr El- Sheikh Governorates. The performed control techniques were run along May 2016, upon inspected honey bee colonies of Carniolan hybrid, which were choosed to study and evaluate the efficiency of different used materials for the management of the American foulbrood (AFB) disease. These tested materials implied the antibiotics: Tylosin®, Terramycin® and Sulfa dimidin sodium® 20%. The following natural materials: Cinnamon oil, Propolis, Ginger, Aloe vera and Aprogin (Aloe vera+ Ginger+ Propolis) part / part. The obtained results elucidated that all of the tested materials were effective against AFB disease. Under the laboratory conditions Tylosin® gave higher efficient effect expressed by inhibition zone with 2.77 cm diameter, versus Propolis which was the lowest efficient material (0.13 cm diameter). The other tested materials of Cinnamon oil, Aloe vera, Terramycin®, Sulfa dimidin sodium® 20%, and Ginger gave varied efficiency represented by more or less inhibition zone diameters of 2.067, 1.933, 1.83, 0.77 and 0.16 cm respectively. In the treated apiaries Tylosin® gave higher reduction - 94.1%, while Ginger gave the lowest efficacy with 40.6% reduction.

Two field experiments were conducted during the 2013 and 2014 summer seasons to investigate the effect of planting dates and planting patterns on productivity and quality characters of Egyptian cotton cultivar Giza 86 (Gossypium barbadense L.). Effects of planting date were more pronounced on the studied phenological characters, yield and yield components than the planting patterns. The fiber technological traits including micronaire-reading, fiber maturity, fiber upper half mean length (UHML), uniformity index (UI), short fiber (SF) and fiber strength (Str.) were least affected by either planting dates or planting patterns. Results suggest that growing cotton on the 1st of April is more suitable than delayed sowing for the cultivar Giza 86 and that the standard sowing of seeds on one side of the ridge, in hills 25 cm apart, resulted in better growth characters and highest yields. Also growing cotton on the wide ridges of the preceding wheat crop is not recommended as it resulted in reduction in yield and its components.

Perception of soil’s history is an essential in addressing the imperious issues related to the sustainable agricultural development and land degradation in the hyper arid and arid regions. Therefore, the current work was undertaken to appraise of pedogenesis and parent material uniformity using Computer Controlled Scanning Electron Microscopy (CCSEM) technique. Five soil profiles (P1, P2, P3, P4, and P5) were selected for study on a topo-sequence model representing most of ground elevations of some soils adjacent to Bani Mazar-El Boiety road at western hyper arid desert of El Minia, Egypt (30о15`40" to 30о28`58"E and 28о31`40" to 28о33`00"N 100 to 170 m A.S.L.;54 km2). The data of CCSEM showed that the weighted means (%) correlated to the ground elevation of Opaque minerals varied between 30.18 at (150-160 m; P4) and 43.81 at (140-150 m; P2) while Pyroboles diverged between 40.85 at (150-160 m; P4) and 92.80 at (140-150 m; P5), Zircon (Z) ranged between 0.85 at (140-150 m; P2) and 15.79 at (160-170 m; P3), Rutile (R) values were 2.14 at (160-170 m; P3) and 30.09 at (150-160 m; P4), contents of Tourmaline (T) were 0.72 at (110-120 m; P1) and 6.51 at (150-160 m; P4), Garnet varied between 0.17 at (160-170 m; P3) and 0.86 at (140-150 m; P2) within the studied soils, reflecting the heavy mineral suite was influenced by topo-sequence of the research area also indicating the study soils are recently formed, weakly developed, and have low effect of pedogenic processes. Irregular vertical distribution with depth of Z/T, Z/R, Z/R+T ratios, and index figure proved that soil parent materials were stratified in nature and apparently formed of multi-depositional regimes. Scanning electron micrographs also confirmed that the investigated soils most probably transported and originated by water agent to distances not far away. The same conclusions have been indicated by applying the grain size analysis of sand fraction reported by Folk and Ward (1957).

Biochar is usually produced from crop residues (feedstock) by pyrolysis process under controlled conditions in specialized reactors. The characterization of biochar properties produced under field condition is limited. The objective of this study was to compare the physicochemical properties of biochar produced from two feedstocks; sugarcane bagasse feedstock (SCBF) and rice husk feedstock (RHF), under traditional field conditions (primitive) and controlled conditions. The temperature of traditional pyrolysis process was kept around 500 °C. However pyrolysis temperature under controlled conditions was repeated at 450 °C and 550 °C. In general, the results showed that increasing pyrolysis temperature decreased biochar yield and increased volatile matter, total surface area and total pore volume which were higher in RHBs than in SCBBs, the pHs of both biochars were to the alkaline range, ash and Si percentages of RHBs were higher than that of SCBBs. Furthermore, the C percentage which was higher in SCBB than in RHB. The FR-IR spectral showed that the presence of free OH group and C-H stretch in both feedstocks disappeared in produced biochars under different pyrolysis conditions. The SEM images showed the presence of longitudinal pores in SCBF while SCBB (550 °C) contained longitudinal structure and fewer micropores, while the images of the RHF showed disturbed order of elongated pores which have been changed to developed pores in RHB (550 °C and traditional). The data of XRD analysis of SCBF indicated the presence of cellulose and disappeared in its three biochars while, XRD data of RHF and RHBs indicate the presence of amorphous silica and quartz. Both biochars produced in the field using traditional pyrolysis unit showed approximately biochar properties as those produced under controlled condition (550 °C).

Two different methods were carried out as an attempt to increase the honey production of A. mellifera colonies( Hybrid) in Egypt. The first method was conducted during winter of 2015/2016 season, includes and three different diets; skimmed soybean, (A) chickpea, (B) and yellow corn flour(C). These supplementary diets were used to fed bee colonies during dearth period to increase their production. Results revealed an increase in sealed brood yield to 1290.0±48.47 inch2 with daily egg laying of 2956.2±111.1 eggs/colony for colonies fed on soybean diet (A), which was the best diet as compared to chickpeas (B) and yellow corn diets (C). In addition, diet (A) showed the highest number of queen cells (138.6±5.65 cell/colony) with the highest cell length (14.9±0.38 mm/queen cell). Moreover, these colonies showed the highest honey production (6.82 ± 0.33 Kg/ colony) during the period of citrus blossom season. A queen exclusion system, the second method, was conducted to increase honey production through out three nectar seasons of citrus, clover and cotton. Total honey was 91.45 kg/10 colonies with amean of 9.15 kg /colony. In clover season, honey production was 53.78 kg/10 colonies, with a mean of 5.38 kg/colony, while in cotton season the colonies produced the least amount of honey of 43.14 kg/10 colonies with a mean of 4.31 kg/colony. There were highly significant differences among the colonies that provided with the queen excluder system on one side and the other control colonies on the other side. Statistical wise, the difference was sigmi ficamt between queen exclusion system ant the control.

This study was carried out to determine quality changes of Nile tilapia (Oreochromis niloticus) and grey mullet (Mugil cephalus) stored in ice. Changes in sensory and microbiological attributes were evaluated during 16 and 14 day of storage for Nile tilapia and grey mullet, respectively. The overall sensory scores of both raw and steamed Nile tilapia and grey mullet gradually decreased with the ice storage. Highly significant correlation was found between the overall sensory scores of both raw and steam cooked Nile tilapia and grey mullet and storage time. The shelf life of Nile tilapia and grey mullet were 8 days in ice. The mesophilic aerobic bacterial count of Nile tilapia and flathead grey mullet flesh increased gradually during storage in ice from 2.38x103and 7.67 x102 CFU/g flesh to 4.10x104 and 2.13 x104 CFU/g flesh after eight day of ice storage. The psychrophilic aerobic bacterial count increased gradually during storage in ice from 5.97x102 and 4.76 x103CFU/g flesh to 6.30x104 and 1.66 x105 CFU/g flesh after eight day of ice storage. Psychrophiles had faster rate of increment during storage in ice, compared to mesophiles. Based on results of sensory evaluation the iced raw and steamed Nile tilapia and grey mullet samples could be classified into three categories of quality grade as follows :(1) high quality grade (stored in ice for not more than 4 days) (2) acceptable grade (stored in ice for more than 4 days, but less than 8 days), (3) unacceptable grade (stored in ice for more than 8 days).

M. H. Yossif
Constant and accurate change detection of land cover/land use features is highly significant to interpret the correlation between human activities and natural phenomena in order to make better decisions and for investigating the processes and patterns of landscape changes over time and the impact of these changes on sustainable development. Soil salinization is a major problem affecting productivity of irrigated lands. Managing salinity to minimize environmental impact is a prerequisite for sustainable irrigated agriculture. The current study aims at detecting, classifying and mapping the current status for land cover types, salt affected soils and their changes in quantity that have taken place in Siwa Oasis during the period from 1987 to 2017, based on satellite imagery data, GIS facilities, statistical analysis, ground truth and laboratory analysis. An approach of multi-temporal mid resolution satellite images of TM 1987, and OLI 8 2017 combined with visual interpretation, supervised classification and new remote sensing indices namely NDVI to enhance accuracy of land cover classification was used. The study employed normal image classification, and developing model from ECe vs NDSI to produce maps for salt affected soils during the period under study. Results showed that the study area has different land cover / land use units; i.e. Salt marches, Sabkha, Cropland, Grassland, Bare Land, Urban, Lakes, Sand dunes, and Hills. During the study period, a very severe land cover change has taken place as a result of mismanagement of land resources. Change detection at the study area explains the rapid increase of saline lakes and salt marshes, and the consequent hazards to the cultivated lands, roads and archeological sites and urban areas over the last three decades. These changes in land cover led to land degradation and water logging in many parts of the study area. In 1987, very slightly saline soil area was the largest in extent34.1%of the total area whereas strongly saline,slightly saline and moderately saline soils covered27.0%, 17.4% and 17.1%, respectively,of the total area.In 2017, strongly saline area increased as compared to 1987and contributed for 39.1% of the total area, while very slightly, slightly saline and, moderately saline areas represented 18.9% and 13.2% and 14.9% respectively of the total area. Most of the salt affected areas were on shallow water table. The results indicate that long-term irrigation activities would affect agricultural potentiality of the area in the future. RS, GIS, NDVI and NDSI tools are efficient and feasible for detecting land cover/land use and salt affected areas from satellite images.

Asmaa
H. A. Ahmed
Bakground:Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health, leading to reduced life expectancy and/or increased health problems. Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis.Obesity is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, endocrine disorders, medications, or psychiatric illness. Objective: This work aimed to study the effect of phyllanthus and costus aqueous extracts on inflicted obese rats. Materials and methods: Thirty mature male albino rats weighing 150±5g were divided into 6 equal groups (n=5 rats each); one group was kept as a negative control, while the other 5 groups were fed for four weaks on high fat diet ( 40 % of calories as fat) to induce obesity, one group of them was left as positive control group (C +ve) while the rest four groups were given orally two doses(300 and 600 mg/kg) of phyllanthus and costus aqueous extracts. At the end of experimental period (28 days), blood samples were collected for serum separation to determine serum level glucose, Apolipoprotin B, liver enzymes (AST, ALT and ALP), total cholesterol, triglycerides, atherosclerosis index,lipoprotein fraction (HDLc, LDLc and VLDLc), kidney function(creatinine, urea and uric acid) and histopathological examination for the liver and heart. Results: The obtained results demonstrated that phyllanthus and costus aqueous extracts caused significant improvement in seurum glucose ,liver enzymes, lipid profile, apolipoprotienA and kidney functions in inflicted obese rats. Conclusion: According to the results obtained, phyllanthus and costus aqueous extracts could be used for obese treatment and to improve vital functions of the body and weight loss.

Jatropha curcas seed cake (J.S.C.) is a useful organic byproduct containing considerable amounts of nitrogen, phosphrous, potassium and micronutrients. It can be considered as a green economy soil amendment. Jatropha curcas seed cake was used as an attempt to enhance soil health and to sustain soil productivity. The objective of this study, therefore, was to investigate the effects of Jatropha curcas seed cake (J.S.C.) as an organic fertilizer and NPK as chemical fertilizers on the health parameters of sandy and calcareous soils cultivated with wheat (Triticum aestivum L .). The results indicated that the percentages of N, P and K in J.S.C. were 2.63%, 0.23% and 3.1% respectively. The results assured that application of the organic fertilizer (J.S.C.) and chemical fertilizers (NPK) had positively affected soil health parameters. Using organic and chemical fertilizers decresed bulk density of sandy and calcereous soils compared with the control treatment. And increased aggregate stability index. Soil organic carbon was increased by using Jatropha seed cake as organic fertilizer. In addition, the differences in dehydrogenase activity were highly significant when combined with different levels of organic and chemical fertilization with the two used soils. The soil pH decreased as the levels of Jatropha seed cake increased, while the EC was increased. The increasing application of jatropha seed cake and mineral fertilizationincreased the concentration of macro and micronutrients in plant and soil. The results indicated that the decomposition of jatropha seed cake is a microbiological process, which release inorganic forms of nutrients (N, P and K). It is also that addition of jatropha seed cake to sandy and calcareous soils positively affected the physical, chemical and biological indicators of the soil health.

Studying the relationship between soil properties and crop yield is one of the most important tasks that should be considered under rainfed conditions. The cropping system in the north western coastal zone is mainly includes of olive and fig grown under rainfed conditions. The intercorrelation among soil properties and their influences on olive and fig yields was investigated. Therefore, multiple regression analysis was employed to generate coefficients for relative contributions of selected soil properties such as soil depth, gravel, soil texture (expressed by sand, silt, and clay), salinity, pH, and calcium carbonate on crop yield. Data of olive and fig yield were collected during 3 consecutive years of 2013, 2014, and 2015 from two different locations, namely wadi Hashem basin (7 sites) and wadi El Heriga basin (9 sites). The collected soil data were interpolated and mapped across the study areas. Statistically, the Pairwise comparisons of crop production demonstrated that there was a significant difference among some of the studied sites in regard to their yield potentiality. To predict the crop yield of the studied plants based on the selected soil properties, Partial Least Square Regression Model (PLSRM) was used. It depicted a profound predication model of olive and fig yield, where it produced R2 of 0.892 with RMSE of 0.093 and R2 of 0.995 with RMSE of 0.042 for olive and fig respectively. Eventually and for the current study, it could be concluded that most of the studied soil properties have a great influence on olive and fig yield under the rainfed condition.

Maize (Zea mays, L.) production considered as one of the most important creal crops in Egypt to face the human and animal essential needs. In this respect, to increase the maize production, some continuous extension efforts had been done at both horizontal and vertical levels to study response of some new maize hybrids to mineral and nano- fertilization. Two field experiments were conducted at the Experimental Farm of Faculty of Agriculture (Saba- Basha), Alexandria University, Abess Region, Egypt, during two summer seasons of 2016 and 2017. A split plot design in three replicates was used. Main plots contain of four fertilization treatments “Mineral fertilizer (K and P) as foliar application, Mineral fertilizer (K and P) in soil, application of Nano- fertilizer (K and P) as foliar application, and mineral as soil application (K AND P) + nano- fertilizer as foliar (K AND P)”. While, sub-plots contained three yellow maize hybrids “Single Cross 162 (S.C. 162), Single Cross 166 (S.C. 166) and Single Cross 168 (S.C.168)”. The obtained results revealed that application of mineral fertilizer in the soil + foliar application of nano- fertilizer recorded the highest value of plant height, ear length and number of rows/ear, number of grains/row, number of grains/ear, 100- grain weight, biological, straw and grain yield. However, S.C.168 hybrid gave the highest grain yield and its components in comparison with other hybrids. On the other hand, interact maize hybrid S.C. 168 with foliar application of Nano- fertilizers (K and P) and soil application of mineral fertilization by K and P increased yield and its components of maize crop under the study Alexandria Governorate conditions.

3-Acetyl coumarin and Benzo-4-methyl coumarin were synthesized and confirmed for their chemical structures by their melting points; carbon and hydrogen analysis in addition to their spectroscopy measurements By U.V, I.R , H1-NMR and M.S. These two compounds were evaluated for their fungicidal activities against Alternaria solani and Fusarium oxysporum in comparison with mancozeb as standard fungicide using radial growth method. The bactericidal of the two compounds were determined against Erwinia amylovora and Ralstonia solanacearum in comparison with streptomycin using agar disk-diffusion method. The results indicated that the synthesized benzo-4-methyl coumarin and 3-Acetyl coumarin have fungicidal and bactericidal activities but less than standard (mancozeb and streptomycin) respectively. It also was found that Benzo-4-methyl coumarin was more active against the tested fungi Alternaria solani and Fusarium oxysporum, and bacteria Erwinia amylovora and Ralstonia solanacearum than 3-acetyl coumarin.

Khaled
M.H. Abd El Salam
The present study was conducted at Rice Technology Training Center (RTTC) to study the effect of milling time on physical properties and proximate chemical composition of some Egyption rice cultivars. Newly harvested certified seeds in 2014 and 2015 growing seasons of five rice cultivars namely, Sakha 103, Sakha 105, Giza 177, Giza 181 and Giza 182 were provided by Rice Research Training Center, Sakha, Kafr El-Sheikh, Field Crop Research Institute, Agriculture Research Center, Egypt. A split plot design with three replicates was used. The main plots were devoted to rice cultivars and the sub plots were occupied by different milling times (30, 50, 70 and 90 seconds). The results showed significant differences between cultivars for most studied characters. Comparison between means showed that rice cultivar Giza 177 gave the highest values for whiteness degree (37.72 and 38.26 %), grain width (2.92 and 2.88 mm) and grain thickness (2.16 and 2.12 mm) in 2014 and 2015 growing seasons, respectively. Moreover, the highest values for broken (13.97 and 14.86 %), grain length (6.4 and 6.27 mm) and grain shape (2.86 and 2.90 L/W) were noticed with Giza 181 rice cultivar in 2014 and 2015 growing seasons, respectively. Furthermore, Giza 182 rice cultivar gave the highest values for crude protein (8.07 and 8.25 %) and starch (75.38 and 75.65 %) in 2014 and 2015 growing seasons, respectively. Sakha 105 rice cultivar showed the highest values for rice bran (8.78 and 9.17 %) in 2014 and 2015 growing seasons, respectively. Increasing milling time from 30 to 90 seconds significantly increased rice bran %, broken rice %, whiteness degree %, grain shape and starch % while, significantly decreased milling %, grain length, grain width, grain thickness, crude protein %, crude fiber %, crude fat %, ash % and non starch polysaccharides %. Interaction between cultivars and different milling times indicated that the highest rice milling (75.31 and 75.62 %) was recognized with Sakha 105 rice cultivar and milling time 30 seconds.

This study was conducted at Rice Technology and Training Center (RTTC) Alexandria during 2014/2015 seasons. The main objectives of present study were to determine the effect of parboiling and storage periods on grain quality characters of Giza 179 rice cultivar during 2014 and 2015 rice growing seasons. Fresh harvested paddy was adjusted to 14% moisture content and then parboiled to evaluate the effect of parboiling. After parboiling the samples were stored for three storage period, i.e. 3, 6 and 9 months to investigate the effect of storage conditions on the parboiled rice. The results indicated significant differences for most studied characters during both study seasons. Storage for nine months gave the highest values for hulling %, milling %, broken %, water uptake, cooking time, protein amylase and elongation during both study seasons. While, the highest values for 1000 grain weight, hardness, gel consistency and gelatinization temperature were noticed for control during both seasons.

Two field experiments were conducted at El-Bostan area at Aly Mubark experimental farm south Tahrir region, El Behira Governorate (300 54 N, 290 52 E, and 25 m above sea level), during 2012/2013 and 2013/2014 to study the effect of humic application with/without foliar application of different potassium source (potassium nitrate, potassium silicates, potassium humate, potassium sulphate) on sweet potato yield and quality characteristics under drip irrigation system. The results indicated that humic acid applications significantly increased the total tuber yield and all measured growth parameters of sweet potato. The relative increases of total tuber yield, marketable tuber yield, average tuber weight, tuber dry weight, foliage dry weight and leaf area were 6.64, 5.24, 7.47, 19.07, 4.35 and 7.92 %, respectively. Humic acid applications significantly increased total nitrogen, potassium and phosphorous content of sweet potato tubers. Also, foliar application of different potassium sources significantly increased total tuber yield of sweet potato and the most of quality characteristics. Potassium nitrate (KN) and potassium silicates treatments have the highest ability to increase the yield and other growth parameter than other potassium sources (potassium humate and potassium sulphate) under sandy soil condition. Interaction effects between humic acid and foliar application of different potassium sources indicated that there was a significant effect between soil application (fertigation) of humic acid and the foliar application of different potassium sources except for tuber potassium and phosphorus content and also, for available nitrogen, potassium and phosphorous in soil at harvest stage. Calculated water use efficiency (WUE) for total tuber yield increased with increasing rates of soil application of humic acid for the two growing season (2012/2013-2013/2014). Relative increases in WUE for total tuber yield were 4.46 and 11.65 % for HA2 and HA4, respectively as a mean value of the tow growing seasons. Also, WUE for marketable yield were more affected by soil application of humic acid compared to WUE for total yield, where the relative increases were 6.07 and 14.51 % for HA2 and HA4, respectively as a mean value of the tow growing seasons. Potassium silicate have the highest WUE for total tuber root yield values 3.76 ton/m3 followed by potassium nitrate 3.61 ton/m3 while potassium sulphate have the lowest WUE for total tuber root yield 3.20 ton/m3 as a mean values of the two growing season. It can be concluded that humic acid at rate of 4 kg/feddan with potassium silicate as a foliar application was good practice to increase sweet potato production under sandy soil condition.

The current study presented an expert system technology of alfalfa (ESTA) in terms of computer programs designed to mimic the reasoning of human experts. These programs, like a human expert, are able to take into account the relative importance of different criteria to the user. These program are useful in select varieties aginst biotic and abiotic stress. It may be more important to the user, however to find resistant varieties to veriticillium wilt. and expert system is able to search a computer database to select the varieties that best reflect this particular bias.The result of this search is a list of cultivars ranked as to how well they meet the user's request. The study describes a microcomputer program called ESTA which is an expert system for alfalfa cultivar selection. Also ESTA is an expert system used as an educational tool for extension people and the alfalfa growers. It is designed to incorporate detailed information about alfalfa production regarding site, soil, machinery, management levels, and yield information to simulate the annual costs and returns over the alfalfa stand life. ESTA requires information from several domains of expertise such as Agronomy, Entomology, Agricultural Engineering and Agricultural Economy. ESTA is a form of artificial intelligence, may soon become an important management tool for agribusiness dealers, county agents, agricultural consultants, and farmers. An expert system technology can make the specialized knowledge of an expert available to farmers when making critical management decisions. ESTA also informs the user as to how the recommendations or conclusion had reached on the screen or on the print – out. This expert systems modules the procedures used by a forage expert in determining agro economic recommendations for successful establishment and production of alfalfa. With this expert system, information is readily available to alfalfa producers for making management decisions relative to liming, fertilization, irrigation, drainage, weed control, longevity of stand, variety recommendations, and method and rate of seeding.

The present investigation has been conducted in the two successive summer seasons of 2014 followed by the winter one of 2015, for the purpose of appraising yield losses to potato tubers caused by the two key subterranean insect pests: Gryllotalpa gryllotalpa(L), Penitodon bispinosus Kust Potato plants were treated with two recommended doses of seven insecticidal baits at 70 and 85 days from sowing. These poisonous baits were Fipronil, Chloropyrifos methyl, Fentrothion, Dimethoate, Azadirachtin,Bacillus thuringiensisand Beauveria bassiana. In the summer season of 2014, the obtained data revealed that loss percentages were 7.86, 9.13, 11.62, 12.5, 25, 25.01, 25.63 and 50 for tubers treated with Fipronil, Chloropyrifos methyl, Fentrothion, Dimethoate, Azadirachtin, B.T, B. bassiana and control, respectively. Correspondingly 2015 as a winter season for the crop, these percentages were 3.76, 6.24, 12.5, 12.51, 25, 28.12 and 40.62% for the control successively. It is worth mentioning, that loss percentages are considered as a prerequisite step for the determination of seven economic injury levels for each insect pest. The computed economic injury levels (EILs) values pertaining to G. gryllotalpa were 0.1, 0.11, .011, 0.31, 0.10, .014, 0.17, insect/100 tubers as a result of using Fipronil, Chloropyrifos methyl, Fentrothion, Dimethoate, Azadirachtin, B.Tand P. bispinosus, respectively. Whereas in case of the B. coriacea, the economic injury levels (EILs) values were 0.41, 0.65, 1.44, 0.64, 1.81, 0.52 and 1.23 insect /100 tubers were also due to the application of the same poisonous baits, respectively, for P. bispinosus, G. gryllotalpa plantation of 2014. In the season 2015, the EILs values due to infestation by G. gryllotalba were 0.54, 0.25, 0.18, 1.43, 0.36, 2.8 and 0.25 insects/100 tubers for Fipronil, Chloropyrifos methyl, Fentrothion, Dimethoate, Azadirachtin, B.Tand Beauveria bassiana baits, in respect. Corrispondingly, EILs the P. bispinosus were0.1, 0.1, 0.1, 3.8, 0.41, 0.22 and 0.31 insect/100 potato tubers for the some applied baits, in respect.

The present study was conducted at the Tissue Culture and Plant Micropropagation Laboratory of Floriculture, Ornamental Horticulture and Landscape Gardening Department, Faculty of Agriculture, Alexandria University, during 2014 and 2015, to study the effect of five different concentrations of phenylalanine (0, 0.5, 5, 10, and 15 mg/l) and four different concentrations of sodium chloride (0, 2000, 4000 and 6000 mg/l) on the production of some secondary metabolites in in vitrocultures of Mentha longifolia using shoot tips and leaves. Leaf segments about 1 cm2 and shoot tips consisting of 3-4 cm long stem segments containing three auxiliary buds (as explants) wereplanted on MS medium supplemented with NAA (0.25 mg/l) + BAP(2.5 mg/l ) + 30 g/liter sucrose + 7 g/liter agar for shoot regeneration from shoot tips, while MS medium contained 2,4-D (4 mg/l) + BAP (0.5 mg/l ) for callus induction from leaf segments, the pH was adjusted to 5.8±0.02.Plantlets were subjected to 16 hours light and 8 hours darkness (2000- 2500 lux for 16 h/d provided by fluorescent tubes), the temperature was adjusted at 25º C ± 2 and 60-70% humidity.The cultures were incubated for 60 days in case of shoot tips and 100 days in case of leaves for callus induction. Chemical analysis was performed on callus tissues after 60 and 100 days from planting and shoot tissues after 60 days from planting which were produced under salinity levels, phenylalanine levels and their interaction to determine the contents of total chlorophyll, total phenolic, rosmarinic acid and proline in both tissues. From the obtained results in this study, using shoot tips for the production of phenolic acid and rosmarinic acid was superior than the callus. Low concentration of sodium chloride (2000 mg /l) enhanced the production of some secondary metabolites. However high concentrations of sodium chloride (6000 mg /l) leads to slow growth, yellowing of cells and sometimes the deterioration of plants. Uses of intermediate concentrations of phenylalanine (5 and 10 mg /l) enhanced the production of chlorophyll and some secondary metabolites where as high concentration (15 mg /l) does not stop growth and cell division.

Population Parameters and Path-Coefficient Analysis of Tomato Grown under Heat Stress
Elsayed
A. Y. Ahmed
Development of genetically improved heat-tolerant varieties is one of the most important approaches for minimizing the negative effects of heat stress. Although there are many factors causing similar negative effects of high temperature, screening of heat tolerance using fruit set percentage as a direct selection for promising genotypes is the common approach. This study aimed to enhancement of selection capacity for heat stress through dual trends; analysis the genetic and phenotypic information derived from generation analysis in tomato and study the causes and effects of indirect selection for heat stress by path coefficient analysis. Homogenous and heterogeneous generations (P1, P2, F1 and F2) were used for estimation the following traits; fruit weight (g), fruit set %, total yield per plant (kg), fruit firmness (inch/cm2), chlorophyll a/b ratio, total chlorophyll/carotenoids ratio and electrolytes leakage at vegetative (ELV) and fruiting (ELF) stages. High genetic variability (GCV, 37.24) with moderate value of heritability (72.02%) was recorded by total chlorophyll/carotenoids followed by electrolytes leakage at vegetative stage (ELV) with genotypic coefficient of variance of 25.89% along with high heritability that estimated by 82.20%. Results of the path analysis along with heritability and selection gain showed that fruit set % and electrolytes leakage are the two most critical component traits for fruit yield under heat stress condition. On the other hand, the average fruit weight had low indirect effect but highly significant with fruit yield per plant. The electrolytes leakage showed high ability to distinguish the sensitive and tolerant tomato plants at early stage of plant development which can be relied upon in the selection of heat tolerant genotypes. Among the evaluated materials, ten genotypes; 130, 129, 127, 08, 11, 10, 131, 155, 161 and 124 that possessing better heat tolerance performance with high yield that could be incorporated in further tomato improvement programs.

Heavy Metals Risk Assessment for Potato (Solanum tuberosum L.) Grown in Soils at Borg El Arab Region – Egypt
Saad
A. E. Abdelrazek
High concentrations of Co, Cd, Cu, Pb, and Zn were found in potatoes sampled collected from overused phosphate fertilizer - soils, which increased the daily intake of metals in food. However, the ingestion of potatoes from soils affected by phosphate fertilizers posed a low health risk when compared with the health risk index of metal contents of crops grown in such soils. Thishas been recorded in potatoes grown in Borg El Arab west Alexandria. This study found that long-term phosphate fertilizer use led to a growing accumulation of heavy metals in soils. Thus, heavy metal concentrations should be periodically monitored in vegetables grown in these soils. It would also be beneficial to implement effective remediation technologies to minimize possible impacts on human health.

Pot experiments were conducted for two successive seasons in Antoniadis Garden, Ornamental Plant Research, Horticulture research Institute. Alexandria, Egypt. Rose plants were grown in sandy soil incorporated with organic compost of municipal solid waste (CMSW)at two levels (5 and 15% w/w) and polyacrylamide at two levels (0.1 and 0.2 % w/w) under irrigation regime at two rates (250ml/plant and 500 ml/plant / 3 times per week) to study their effect on the growth, flowering, water consumption, chemical contents of rose plants and improvement of hydro-physic-chemical properties of sandy soil under the study. The obtained results showed that the irrigation water rates did not significantly affect the vegetative parameters, the flowering characteristics except for the flowering time that was significantly reduced. The early flowering was recorded at the lower irrigation rate in the 2nd season. The K, chlorophyll and carbohydrates contents significantly increased in one season only. Anthocyanin content did not significantly increase. Pre-planting addition of CMSW at the higher level (15% w/w) significantly stimulated the vegetative parameters in the two seasons. The organic compost at level of 15% w/w of CMSW was more effective in promoting the early flowering (45.9 day) and the heavier flower dry weight (3.26g), prolonged vase life were 7.79 and 7.50 day, maximum number of flowers/plant were 7.82 and 5.08 in the two seasons, respectively. The tallest peduncle was 32.34 and 32.07 cm and the longest duration period was 5.72 and 6.19 in the two seasons, respectively. The N, P and K chemical contents, the total chlorophyll, carbohydrates and anthocyanin were significantly stimulated at the higher level (15% w/w) of CMSW compared to the lower level (5%w/w). Amendment of sandy soil with the hydrophilic synthetic polyacrylamide (PAM) at the level (0.2% w/w) significantly reduced the flowering time, while number of flowers/ plant and flower diameter as well as flower dry weight. The total chlorophyll and carbohydrates contents were significantly accumulated in the leaves as a result of utilizing PAM at level (0.2% w/w). Saturated hydraulic conductivity (Ksat) increase with increasing PAM concentrations. The study recommended to grow rose plants in sandy soil under amended with pre-planting organic compost (CMSW) at level (15% w/w) and PAM at level (0.2% w/w) with irrigation rate at 250 ml/ plant/ 3times per week.

environmental universal issues due to its adverse effects on agricultural productivity and sustainable development. Remote sensing is an important tool for investigating soil characteristics such as soil salinity. In saline soils, the spectral reflectance of salt at the surface or of vegetation execution that was adversely influenced by salt varies with different salinity levels. So, many salinity and vegetation indices have been developed and used. This study used ground data and Landsat Enhanced Thematic Mapper Plus (ETM+) satellite images (visible and near-infrared reflectance) to compare between eleven spectral indices, which encompassed soil salinity and vegetation indices, to determine the best index to the estimations of soil salinity for bare and cultivated soil. Soil samples were gathered from two locations in El-Beheira governorate in Egypt; 24 samples from Wadi-El-Natroun (bare soil) and 22 samples from El-Bostan (cultivated soil) and the soil samples locations were overlaid on ETM+ satellite image to extract the exact index values. The electrical conductivity (EC) measured in saturated soil-paste extract. Among those spectral indices, SI3 showed the highest correlation coefficient with EC (R2 = 0.77) according to linear regression analysis and S6 according to Polynomial regression (R2 = 0.83), followed by S3 for bare soil. NDVI and SAVI get the best result for assessing the soil salinity of cultivated soil (R2 = 0.83 and 0.76) according to Polynomial and linear regression, respectively, followed by RVI.

4- As for nutrition and fodder variable, it was found that 53% of respondents fell under the average knowledge category, 30% fell under the high knowledge category, whereas 17% were of the low knowledge category.
5- There was a relative reduction in the level of respondents’ implementing to the good agricultural practices in the field of dairy production, as for the boosting resistance to diseases variable, it was found that 65% of respondents were of the low and average implementing category.
6- As for animals’ care variable, it was found that 46 % of respondents came under the low implementing category, as for environment variable, results showed that 40 % of respondents were of the high implementing category, and 39 % came under the average implementing category and 21 % were of the low implementing category. As for personal hygiene variable, it was found that 38 % of respondents fell under the average implementing category, 35 % fell under the high implementing category and 27 % came under the low implementing category.
As for nutrition and fodder variable, it was shown that 48 % of respondents came under the average implementing category, whereas 27 % came under the low implementing category.
7- Results showed a significant relationship at (0.01) significance level between the variables: educational qualification, attitude toward modernizing of agricultural practices and the knowledge level of farm animals’ keepers in the field of milk production at the study area. there was also a significant relationship at 0.01 significance level between : educational qualification, animal holing and level of farm animals’ keepers level of implementation to the proper agricultural practices in the field on dairy at the study area.
8- Respondents reported five (5) obstacles that keep farm animals” keepers from implementing the proper agricultural practices in the field of dairy production
i.e. the high price of fodders, the poor, in adequate extension services and information on keeping milk production animals, the insufficient finances for the keepers, difficulty of marketing due to lack of near markets near dairy marketing and the high fees for veterinarian vaccination.
