The present work was carried out during the year of 2012 at two different locations of Maamoura and Montaza Research Branch, Horticulture Institute, Ministry of Agriculture, Alexandria, Egypt on Lantana plant. This study was a trial to improve some characters of the calcareous soil with using two natural soil conditioners i. e. compost and sand. Each compost and sand were added alone to the calcareous soil at a ratio of zero, 25% and 50% or with using an equal mixture of the three materials together (33.3% calcareous soil + 33.3% compost + 33.3% sand) to produce six different growing media. Lantana plants were grown in 25 cm diameter clay pots on 15 March 2012 and they left to grow vegetatively for 45 days, then the plants were arranged in an experiment of randomized complete block design and they stayed for seven months for evaluation. Results revealed that using calcareous soil alone or mixed with sand at 25% or 50% gave the lowest values of most of the studied parameters of Lantana plant (vegetative growth, flower characteristics, and chemical analysis of plant leaves). Besides, adding compost at 25% or 50% to the calcareous soil led to significant increase in almost all the studied parameters of Lantana plant, compared with using calcareous soil alone. Furthermore, using an equal mixture of the three materials had no significant effects on the vegetative growth or the flowing characteristics of Lantana plant, while the content of Lantana leaves of chlorophyll, nitrogen, phosphorus, potassium, and zinc were significantly increased, compared with using calcareous soil alone. From the previous results it can be recommended to add compost at 25% to the calcareous soil for obtaining a suitable growing medium for planting and growing Lantana plant with good quality.

The cereal-based fermented food Egyptian Kishkconstitutes a major source of high quality dietary nutrients for Upper Egyptians and is popular among all social strata. Lactic acid bacteria were one of the main flora which is responsible for fermentation. To-date, kishk is still traditional making and the diversity of LAB in Kishk has not been fully investigated and improving the Kishk throughout using selected cultures for its processing has never been established.In this work, LAB have been isolated from samples collected during traditional making the Kishk. The obtained results showed that the dominant lactic acid bacteria isolates were obligatory hetero- fermentative and Enterococci spp. The homofermentative LAB were found in the first steps of the fermentation. Homofermentative and facultative heterofermentative of lactobacilli were found in the first fermentation process steps and then- almost disappeared after that in Kishk. On the other hand obligatory hetero fermentative and Enterococci spp. were detected in all steps of kishk manufacturing while Lactococcus was a minor isolate during fermentation process. The majority of isolates are γ- haemolytic except one isolate of Enterococci spp. which was β haemolytic. There are significant differences (P≤ 0.01) in organoleptic characteristics (colour, taste, smell, texture, appearance) and overall acceptability among all isolates used to ferment the milk. Fifteen isolates that received the highest levels of overall organoleptic properties are selected as starter culture in improving the Kishk making.

Toxicity of the anthranilic diamid insecticide chlorantraniliprole, the macrocylic lactone insecticide emamectin benzoate, the neonicotinoide insecticide imidaclopride and the bioinsecticide Agree® (Bacillus thuringiensis subsp. aizawi GC-91) against the 2nd, 3rd and 4th larval instars of Spodoptera littoralis (Boisd.) were studied. The joint toxic action of chlorantraniliprole with each of the other three insecticides was also investigated against the 4th instar larvae of S. littoralis. Emamectin benzoate against 2nd, 3rd and 4th larval instars (LC50 = 0.0004, 0.0020 and 0.0048 ppm, respectively) was more toxic than chlorantraniliprole (LC50 = 0.17, 0.51 and 1.5 ppm, respectively), followed by imidacloprid (LC50 = 1.19,43.65and 1085.69 ppm, respectively) and Bacillus thuringiensis (LC50 = 754.65, 1205.67and 2279.91 ppm, respectively) after 96 hrs of treatment by dipping leaf disc tequnique. Chlorantraniliprole/imidaclopride mixtures resulted in antagonistic effect more than the chlorantraniliprole/emamectin benzoate mixtures and chlorantraniliprole/Bacillus thuringiensis mixtures at different concentration levels. The chlorantraniliprole at LC50/other tested insecticides at LC50 mixtures revealed antagonistic effects higher than the mixtures of chlorantranliprole at LC25/other tested insecticides at LC25. The mixture of chlorantraniliprole at LC12.5/Bacillus thuringiensis at LC12.5 resulted in an additive effect. Therefore, mixtures of chlorantraniliprole with these tested insecticides can't be used for cotton leafworm control.

Twoexperiments were conducted at Sakha Agriculture Research Station, during the two successive summer growing seasons of 2012 and 2013 to estimate and analysis water requirements components for some Egyptian rice varieties (Oryza sativa L); namely cvs. Giza 178, Sakha 102 and Sakha 104 and to evaluate and compare the estimated rice crop evapotranspiration (ETc) values computed using Hargreaves, Penmen-Monteith and Class A pan methods used for (ETc) with the measured actual rice evapotranspiration (ETa) using micro- paddy lysimeter used for (ETa) to evaluate the best method for estimating the reference evapotranspiration which suitable with North Nile Delta conditions. Results showed that evaporation (E) is the highest component of total rice water requirements (WR) during the whole growing season stages for cv. Giza 178 with an average 39.8%, followed by cvs. Sakha 102 and Sakha 104 with an average 38.3 and 38.2%, respectively. However, Transpiration (T) is the lowest part of WR for cvs. Giza 178, Sakha 102 and Sakha 104 with an average 21.0, 20.1 and 21.4%, respectively. For percolation (P) is major for Sakha 102 and Sakha 104 varieties with an average of 41.6 and 40.4%, respectively. Meanwhile, the lowest value of P (39.2%) was lost from Giza 178. Mean values of ETa for cv. Giza 178, Sakha 102 and Sakha 104 were 6.1, 6.0 and 6.0 mm day-1,respectively. Although mean values of the estimated rice crop evapotranspiration resulted from Hargreaves, Penmen-Monteith and Class A pan methods were underestimated actual rice evapotranspiration, but Hargreaves and Penmen-Monteith methods performed best for North Delta, Egypt because of the least amount of error and least percentage deviation between ETa and ETc. Crop water productivity (CWP) were 0.85, 0.86, and 0.87 Kg m-3 for rice cvs. Giza 178, sakha 102, and Saka 104, respectively. Also results indicated that the values of crop water use efficiency (CWUE) of rice for cvs. Giza 178, Sakha 102 and Sakha 104 were 1.53, 1.55 and 1.46 Kg m-3 respectively. So, Hargreaves and Penmen-Monteith methods could be recommended for saving irrigation water with planting rice cv. Giza 178, which gave higher water productivity.

The remediation of the oxamyl pesticide, applied, at a rate of 50 µg/gm soil and amended with different materials namely, Tergitol NP9 (nonionic surfactant), charcoal, lorandeat and iron fillings at rate of 300, 250, 250 and 300 Kg/Fadden, respectively, was investigated. The oxamyl residue levels in loamy sand was extracted at different time intervals after treatment based on the solid phase extraction (SPE) with methanol and then analyzed by HPLC. Only the peak corresponding to oxamyl was observed in the chromatogram and no intermediate metabolites could be detected. At the end of the experiment (21 days), the dissipation percentage of oxamyl reached about 88, 78, 73 and 72% in soil amended with NP-9, Fe, lorandeat and charcoal, respectively. The rate of disappearance was 2 times higher than in unamended-soil, while Fe, lorandeat and charcoal enhanced the dissipation rate by 1.77, 1.65 and 1.61 times, respectively. The disappearance rate constants and half-life values of the compound were obtained from the exponential decay equations. The decomposition of oxamyl in the control, charcoal and lorandeat followed the first order kinetics with t1/2 of about 22.08, 13.8 and 13.2 days. On the other hand, a biphasic model was assumed to explore the disappearance of oxamyl in soil amended with NP-9 and Fe where the rate of disappearance in the first phase was faster than the second phase. This is clearly reflected in the half-life (t0.5) values for the first and second phases, where the t0.5 values of oxamyl ranged from 3.3 to 12.7 and 6.5 to 15.6 days, respectively. The results demonstrated that using NP-9, Fe, charcoal and lorandeat may offer an efficient remediation treatment for oxamyl-polluted soil.

This study aimed to measure electronic readiness (E-readiness) of extension personnel in Assiut governorate for utilizing ICTs in agricultural extension. The study used the three components determined by Bilbao-Osorio et al. (2014) in order to measure extension personnel’ E-readiness in Assiut governorate. Data were collected by using questionnaire from 117 personnel representing 39.6% of the total number of extension personnel in Assiut governorate (295 Personnel). The results showed a low E-readiness of the respondents for utilizing ICTs in agricultural extension; which is supported by the low scores of the three components (infrastructure and digital content, the respondents’ affordability to utilize ICTs in agricultural extension in Assiut governorate, and the respondents’ skills in ICTs).

Effect of Kaolin and Fulvic Acid Antitranspirants on Tomato Plants Grown under Different Water Regimes
Aggag,

Abdallah,
A.E.
This study was carried out to evaluate effects of kaolin (KA) and fulvic acid (FA) as antitranspirants (ATs) on relative water content (RWC) of leaves, net CO2 assimilation rate (CO2 AR), yield, fruit quality and irrigation water use efficiency (IWUE) of tomato plants (Solanum lycopersicum L.). The plants were grown under three water regimes based upon crop daily water consumptive use (ETc). These regimes included 100%ETc, 75%ETc and 50%ETc. Field experiments were achieved for two successive seasons 2012 and 2013 under drip irrigation system in sandy soil at El-Bostan, El-Beheira Province, Egypt. The results revealed that both ATs enhanced effectively the physiological activities and yield production of tomato plants, particularly at water regime of 75% ETc, but they did not compensate the negative effects caused by sever water regime of 50% ETc. FA antitranspirant was more effective than KA. Under water regime of 75%ETc, application of 1.5 FA ml L-1 at 21-day intervals increased IWUE by 34.82% compared to untreated plants. Foliar spray by FA reduces the values of crop response factor than KA in the two seasons. These led to conserving soil water and thereby reduce the applied water by 25% of irrigation water. In comparison to untreated FA plants, the FA (75%ETc) led to decreases in the yield to 93.4% of that irrigated at 100%ETc. There were no significant differences in the fruit quality (titratable acidity and vitamin C) between both ATs treatments.

El-Shehawi
Plant aquaporin genes regulate water movement through cellular membranes and determine the plant water relationship and plant adaptation to different environmental stresses. The expression of three PIP genes and one TIP gene was studied in response to PEG-induced dehydration in four Egyptian commercial wheat varieties. Semiquantitative estimation of RNA level via cDNA synthesis and PCR was used. Results showed that variations among the four studied genes in wheat varieties under normal condition and in the presence of PEG. Under normal conditions, Misr1 exhibited the highest level of PIP1 expression, Sids1 exhibited the highest level of PIP2 and PIP3 expression, and Gemmiza7 exhibited the highest expression of TIP1. Under dehydration induced by PEG, all three PIP genes (PIP1, PIP2, PIP3) showed various levels of transcription downregulation. PIP1 gave the highest level of downregulation in all varieties. Sids1 showed the highest response to PEG-induced dehydration because under normal conditions it exhibited high PIP expression and low TIP expression, whereas under dehydration condition it showed high downregulation of PIP genes and high upregulation of the TIP gene. This would be related to its high adaptation to dehydration. Results of this study will enhance our understanding of plant aquaporin expression profile and utilizing this in improvement of plant tolerance to dehydration.

Reducing the Amount of Nitrate and Nitrite in Anna Apple Fruits by Using Inorganic N Along with EM, Yeast and Humic Acid
Osama Aly Mohamed
El-Sehrawy
During 2009 and 2010 seasons, three bio-stimulants namely EM (Effective Microorganisms), yeast and humic acid were used as a trial for replacing inorganic N partially in Anna apple orchard. Combined application of inorganic N beside any bio-stimulants was favorable than using inorganic N alone in improving growth, nutritional status of the trees as well as yield and fruit quality. The best biostimulant was EM. Humic acid ranked the second position in this concern. For reducing pollution due to nitrate and nitrite in the fruits and for improving production of Anna apple, it is advised to use N as inorganic N at 60 % of the suitable N dose along with application of EM or humic acid each at 30 ml/tree/year.

The horizontal expansion reclamation of new land added to the land of the valley and delta one of the most important agricultural development hubs in Egypt, because of its great importance in facing a lot of problems of overpopulation, and high unemployment rates among young people. In addition to the fact that land is a new horizon for expansion in agriculture economic value byexporting crops and increasing the proportion of the contribution of the agricultural sector in the gross national product. An example of the spread of citrus cultivated crops in the new land, and is characterized by high production high quality and characteristics desired in the domestic and global market.
As the growers of citrus in the new land differ in their behavioral patterns between traditional and novel in solving many of the problems they face, including crops infected by the fruit fly, which caused them heavy losses not only in the quantity of production, but the possibility of marketing as well, affecting negatively on the economic drive revenue. For this reason, researching the problem has been focusing on the will levels of specific behavioral pattern regenerative with citrus growers in the new territories in the fight against fruit flies in Al-Bustan area, NUBAREYA.
The research findings have resulted in the existence of relations correlation significant at the probability level (0.01) between the constituent aspects of the level of the specific behavior will and between each other, and of ((Knowledge farmers respondents level, the extent of their conviction with some knowledge, the level of skill in the application of some of the practices, the extent of their attachment to the application of these practices, whether traditional or novel)) in connection with the fight against fruit flies in citrus crops, including refers to the need to deal with those aspects of a total package, and one at the planning and preparation for the implementation of extension programs, this On the other hand, the need to focus on the personal characteristics of the growers that can be driving them towards the change and supporting it, especially those that proved significant relationship between them and the behavioral aspects of the will at the level of potential (0.01), (0.05), and then the integrated agricultural extension programs- which carry goals, make package changes in constituent behavioral will aspects of growers with a focus on some of the characteristics of personal support for the change- can be a more successful message reliable extension in achieving this philosophy aimed at raising will levels set to choose the style regenerative behavior in various fields, including the fight against fruit flies in citrus crops., which can also be generalized to other areas.

The objectives of this study are: (1) Determining the important factors that affect on the sheep red meat production in the study region, (2) Estimation of the production functions of sheep red meat, (3) Recognizing the important economic indicators that can help in improving the red meat production, consequently increase the production capacity and decrease the food gap of animal protein.
The study has relied on the descriptive analysis method and statistical and econometric analysis to achieve the objectives of the study.
The main conclusions of the study are:
The economic factors determining the sheep red meat production in the sampled farms classes are: (1)quantity of green animal feed, (2)quantity of concentrates, and (3)number of animal units. The economic efficiency for each of these determinants amount to, 1.76, 3.26 and 1.64 respectively.
The economic factors determining the sheep meat production in the farms of second class are: (1) quantity of concentrates, (2)quantity of dried animal feed (3) and cost of animal health care. The economic efficiency for each of these determinants amount to 4.2, 2.4, and 0.0002 respectively.
The economic factors determining the sheep red meat production in the farms of third class are: (1) quantity of green animal feed, (2) quantity of dried, (3) quantity of concentrates animal feed. The economic efficiency for each of these determinants amount to 4.42, 1.57, and 3.93 respectively.
Based on these results increasing farm production of sheep red meat in livestock farms is based mainly on sufficient nutrition, improving the current level of veterinary treatments and environmental care to maintain animal health and productivity.

The present study aimed to investigate the relationship between the level of mercury in urine and the hyperactivity of children in preschool age.in Alexandria city A random sample included 200 children (100 from contaminated areas, and 100 from non-contaminated areas). was taken in the study Also subsample have been chosen (10 For each area) to estimate the concentration of mercury in the urine of children. Data were collected through personal interview questionnaire with children mothers. The most important results could be summarized as follows: Personal and Household Characteristics: 1- 46 % of the mothers from non-contaminated areas had high institute education, compared with 12% only of the mothers at contaminated areas, the differences were significant (P ≤ 0.01) 2- 94% of the mothers in contaminated areas were house wives, compared with 48% in non-contaminated areas, the differences were significant (P ≤ 0.01). 3- Only 8% of the fathers in contaminated areas have high level of education, compared with 49% of the fathers in non-contaminated areas. 4- Income per capita (average of the monthly income) in non-contaminated areas was higher than contaminated areas (608.65 ± 337.58, 248.87 ±101.09) LE respectively, the differences was significant (P ≤ 0.01). 5- 100% of the mothers in non-contaminated areas said gestational age of the child ranged between 36> 40 weeks, compared with 97% in contaminated, the differences were not significant between the two groups. 6- The average birth weight in contaminated areas was (2.97 kg ± 0.42) compared to (3.23 kg ± 0.54) in non-contaminated areas, the differences was highly significant (P ≤ 0.01). Income per capita (average of the monthly income) in non-contaminated areas was high her than contaminated areas (110.14 ±61.14, 77.4 ±58.23)LE respectively, the differences was significant (P ≤ 0.01). 7- The concentration mean of urine mercury was 3.64± 0.558 µg/l in contaminated areas, compared with 1.94 ± 0.433 µg/l in non-contaminated areas. The differences were highly significant (P ≤ 0.01). 8- For ADHD the results revealed that children in contaminated areas had high scores than children in non-contaminated areas; the differences were highly significant (P ≤ 0.01). 9-The results of the correlation coefficients among some variables indicated that there were a negative significant correlation (P≤ 0.01) between educational status of the Parents and Professions, income per capita, the Gestational age of the child and urine mercury concentration. 10-Also, there was a positive highly significant correlation (P≤0.01) between the child's age, the order of the child and the concentration of mercury in the urine of children. Therefor it is recommended to held awareness programs to mother about sources of pollutants especially mercury, and how to avoid exposure to these sources in order to keep their children healthy.

This research aims to identify the level of rural respondents application to wrong environmental practices in four dimensions: water, air, food, and agricultural land; determine the nature of the relationship between each variable of studied independent variables and the wrong environmental practices of rural women for each dimension of the four studied dimensions; determine the relationship among combined studied independent variables and the wrong environmental practices for each one of the four dimensions studied, and finally determine the degree of contribution of each variable of studied independent variables in explaining the variation in the wrong environmental practices for each one of the four dimensions studied.
To achieve the objectives of the research; Nawag village, Algarbia governorate were to be a place of the study. A sample of 150 respondents was randomly chosen of rural women in the village. Data was collected by personal interview using a questionnaire, and frequencies, percentages, probable average, coefficient of simple correlation (Pearson), coefficient of multi correlation , the standard partial regression were used in data analysis.
The main findings of this research were as follows:
- The application level of rural to wrong environmental practices was as high as possible for air, followed by water, then by agricultural land, and finally by food where the percentage of wrong practice wrong in the medium and high level of 80%, 78%, 66.9%, 65.7%, respectively.
- There was an inverse and significant correlation among wrong environmental practices of the respondents for water dimension and the number of family members, media effect, geographical opening, total monthly income of family, living level and unofficial social participation. As well the relationship was inversely correlated for air dimension and both of number of family members, and media effect, geographic opening, total monthly income of the family, living level and unofficial social participation. Regarding food dimension; the relationship was inverse and significant with both of media effect, geographical opening, and total monthly income of the family. Also the relationship was inverse and significant for agriculture land dimension with all of the respondents’ age, media effect, geographical opening, total monthly income of the family, and the living level.
- It was clear that geographical opening variable contributed to interpretation of the variation in the four studied dimensions, while variable of total monthly income of the family contributed in explaining the variation in three dimensions: water, air, and agricultural land. In the other hand; the variable of educational status of respondent contributed to the interpretation of the variation in the two dimensions of food and agricultural land. Each variable of media effects and number of family members, and living level contributed to the interpretation of the variation in air dimension only, while the variable of media effect contributed to the interpretation of variation in food dimension only. It is also noticed that all of these variables has maintained its significant relationship with the dependent variable in each of the full and reduced model for each dimension which indicating the authenticity of these variables in explaining the variation in the dependent variable.
