Due to the increased importance of soil degradation investigation in the Libyan Mediterranean region, soil erodibility-related data is extremely needed. In the present study interrill soil erodibility (Ki) and interrill detachment rate (Di) were estimated using WEPP-formulae. In order to apply the formula, soil properties such as soil texture parameters, organic matter content, exchangeable calcium and saturated hydraulic conductivity (Ks) were measured. The calculated values of erodibility (Ki) ranged between 2.25 x 105 to 5.39 x 105 kg.s.m-4. Multiple regression analysis showed that soil texture parameters, Ks and exchangeable Ca+2 explained about 92% of the interrill detachment rate. The slope factor also played an important role in the soil detachment process. The comparison between the used WEPP-Ki and the soil instability indicators showed that WEPP-Ki equation need to be reconsidered and should include more factors that affect soil structure stability under the Libyan Mediterranean conditions.

The present study was conducted to evaluate the effects of LC50 concentrations of ethanolic plant extracts, Artemisia herba alba (Compositae), Matricharia chamomilla(Compositae), and Melia azedarach(Meliacae), which were 1.807, 0.505, and 1.035 mg/L, respectively (after 24 h exposure), on the 3rd larval instar of Culex quinquefasciatus (Say). Delaying effect of the LC50 were followed up on the life cycle of the insect. The results showed that the concentration used led to a prolongation of the 3rd larval stage as: 23.20± 1.009 and 23.10±1.006 days for each treated group of A. herba alba and M. chamomilla, respectively, while those treated with M. azedarach complate larval stage after 26.3 ± 1.004 days, the untreated larvae 10.78±0.25 days ,and affected proportions entering the pupal stage and developing to pupal stage 20% and 26.6% compared to the control ( 86.49%). It had an impact on female longevity, where females lived longer than males, as well as on sex ratios, with more males than females. These results clearly demonstrate the effectiveness of these extracts to influence the life cycle of this insect. Plant extracts apparrentally acted as a growth regulation and suppressed the develping of the Cx.quinquefasciatus thereby impeding the natural growth of the insect and reducing its damage.

The present investigation was conducted at the Experimental Farm of Faculty of Agriculture, Kafrelsheikh University during 2008 and 2009 seasons. The main objectives of this investigation were to study the association between some quantitative characters in rice, using path coefficient analysis to determine the relative importance of such characters to grain yield variation and estimation of some genetic parameters of twenty five rice genotypes under water stress environments (irrigation every 6, 9 or 12 days). Grain yield was positively correlated with each of number of panicles/plant (under the two severely stressed environments), number of grains/panicle (under the first and the third water intervals) and with panicle length under all environments. Panicle length was positively correlated with number of grains/panicles under all treatments. Fertility percentage was negatively correlated with number of panicles/plant under all environments and positively correlated with 1000-grain weight under the first and the third treatments. Meanwhile, number of panicles/plant was negatively correlated with 1000-grain weight, this may be due to their compensatory relationship. Path coefficient analysis revealed that under the most stressed environments, number of panicles/plant had the largest direct effect on grain yield, while under slight stress (irrigation every 6 days), number of grains/panicle appeared to be the most important yield component followed by number of panicles/plant and panicle length. Phenotypic coefficient of variability (PCV) was, in general, higher than genotypic (GCV) coefficient of variability for different traits, indicating less environmental influence in the expression of different traits. Heritability estimates in broad sense were either relatively moderate or high for all studied traits. Such estimates ranged from 55 to 94% for grain yield and 1000-grain weight, respectively. Relatively higher genetic advance coupled with high heritability estimates was detected for 1000-grain weight and plant height.

Field evaluation of four conventional insecticides and one microbial insecticide against black cutworm (BCW), Agrotis ipsilon, at two locations in cotton during 2008 and 2009 seasons were carried out in this study. Susceptibility of the two field strains compared to the laboratory strain for the five insecticides also was studied in the laboratory. At Abou-Elmatameer location, triazophos and Bacillus thuringiensis var. kurstaki revealed the highest reduction percentages of BCW all over the experiment period during the two seasons. Triazophos caused BCW reduction percentages 91.7, 93.2. 94.1 and 94.5% during 2008 season, and 88.4, 90.6, 90.9 and 89.9% during 2009 season, after 3-, 6-, 9- and 12-days post-treatment, respectively. Bacillus thuringiensis kurstaki reduced BCW population by 68.2, 90.0, 92.7 & 93.2% at 2008 and 69.7, 87.3, 90.6 & 90.5% at 2009 after 3-, 6-, 9- and 12-days post-treatment, respectively. On the other hand, λ-cyhalothrin gave the least BCW control. At Abees location, B.t. kurstaki recorded the highest BCW reduction percentages in the two seasons. During 2008, B.t. kurstaki achieved 73.7, 87.1, 90.0 and 89.4% reduction in BCW population after 3-, 6-, 9- and 12-days post-treatment. These reduction percentages were 71.7, 90.5, 89.1 and 90.9% after 3-, 6-, 9- and 12-days post-treatment, respectively, at 2009. Reduction percentages of BCW achieved by carbosulfan, chlorpyrifos, triazophos and λ-cyhalothrin at 2008 and 2009 were comparable and significantly lower than B.t. kurstaki. Black cutworm reduction percentages achieved by carbosulfan, chlorpyrifos, triazophos and λ-cyhalothrin at Abou-El-Matameer were significantly higher than at Abees in the two seasons. On the other hand, at the two seasons, BCW reduction percentages caused by B.t. kurstaki were not significantly different at the two locations. At the laboratory, Abees strain exerts tolerance ratios higher than Abou-Elmatameer strain to the tested conventional insecticides. The two field strains had no tolerance to B.t. kurstaki compared to the laboratory strain. Therefore, B.t. kurstaki may be considered as a good alternative for controlling BCW.

Two field experiments were conducted under naturally infested orobanche fields at Sakha Agricultural Research Station, Kafrelsheikh, Egypt during 2006/2007 and 2007/2008 seasons. The aim of this investigation was to study the effect of sowing date and broomrape control on seed yield and yield related traits of three faba bean cultivars; Misr 1, Giza 843 and Sakha 2. Three sowing dates; first Nov., mid Nov. and first Dec. beside three doses of glyphosate application; control, 75 cm3/fed. and 75 cm3/fed. twice were involved in this study. A split-split plot design with three replications was used. Sowing date were allocated to the main plots and glyphosate application treatments were allocated in the sub plots while, faba bean cultivars were occupied the sub sub plot. The most important findings could be summarized as follows: The differences among sowing dates were significant or highly significant for all the studied traits in both seasons except for number of pods/plant and biological yield (ton/fed) in the second season. Sowing date on mid-Nov. exhibited the highest values for all the studied traits, but, the differences between the second and the third sowing date were not significant for number of pods/plant and number of seeds/plant (in the first season) also the differences between the first and the second sowing date were not significant for seed yield (ard./fed.) and biological yield (ton/fed) in the first season. Increasing glyphosate doses from zero up to 75 cm3/fed twice were associated with significant increase in number of pods/plant, number of seeds/plant and seed yield/plant, seed yield (ard./fed.). However, the differences between application of 75 cm3 glyphosate once or twice were not significant for seed yield (ard./fed.) and biological yield in the first season. Large variations among the three faba bean cultivars were recorded for all the studied characters. Misr 1 cultivar detected the highest values for all the studied characters however, the differences between Misr 1 and Giza 843 were not significant for seed yield (ard./fed) in the second season and for biological yield in both seasons.

Greenhouse experimental studies were conducted to evaluate certain biological control agents and other chemical compounds belonging to different groups to suppress the population density of root-knot nematodes (Meloidogyne incognita) in the sandy soil on tomato plants cv. Super strain B. The biological control agents were the antagonistic bacterium Pseudomonas flouroscence, antagonistic fungus Trichoderma harazianum and their mixture. Meanwhile, the chemical compounds included cadusafos, fosthiazate, carbofuran and oxamyl, as well as the biopesticide abamectin. The data revealed that carbofuran and P. flouroscenceproved to be the most effective treatments suppressing the final population of root-knot nematodes (Meloidogyne incognita). Both carbofuran and P. flouroscence showed the same effect as the mean reduction of population density reached 92.7%, followed by the mixture ofT. harazianum and P. flouroscence (88.9 %), then T. harazianum alone which achieved a reduction of 88.1%. Fosthiazate was the least effective treatment on population density giving a reduction of 53.7%. Cadusafos gave the highest reduction percentage (55.3%) on galls/5g roots, followed by abamectin, oxamyl and fosthiazate which recorded 54, 53.9 and 51.1% reduction, respectively. Meanwhile, T. harazianum recorded the least reduction in galls (11.5%). Abamectin gave the highest reduction (77.2 %) of root-egg masses/5g roots followed by fosthiazate, oxamyl and the mixture of T. harazianum and P. flouroscence (63.9%, 60.9% and 60.4% reduction), respectively. All the evaluated treatments proved to be effective in enhancing the plant growth of tomatoes and showed indirect effect on the length and weight of root and shoot systems. Abamectin was the superior treatment in increasing the root system length by 44.2 %. on the other hand, the mixture of T. harazianum and P. flouroscence decreased the root system length by 4.1 %. P. flouroscence was the most effective treatment achieving an increase of 88.7 % in root system fresh weight, followed by abamectin and cadusafos which gave 87.4% and 81.0% increasing. However, T. harazianum showed the least increase in root system fresh weight (20.9%). Also, P. flouroscence gave the highest increase percentage of the shoot system length followed by abamectin and carbofuran. In respect to the shoot system weight, abamectin gave the highest increase over all the tested treatments (94.4%), followed by fosthiazate and P. flouroscence which recorded increase of 90.9% and 89.4%, respectively. Vice versa, T. harazianum recorded the least increase in both shoot system length and weight giving increase of 58.7% and 72.8%, respectively, compared with the untreated check.

The repellency and insecticidal activity of ethanolic plant extracts from Rhazya stricta, Caralluma tuberculata , Capparis spinosa, Marrubium vulgare and Argemone ochroleuca were evaluated against red flour beetle, Tribolium castanium in the laboratory. The dosages used were 200, 400, 600 and 800 ppm. Larvae and adult beetle were exposed to the treated wheat flour for 6 days. Mortality percentage was recorded after 2, 4 and 6 days from exposure. The repellent action of the previous plant extracts was also, studied using the same dosages. All of these extracts showed remarkable toxicities in a dose dependant manner. Results showed that complete mortality of T. catanium was achieved by C. tuberculata at the concentration of 800 ppm for both larvae and adult beetle. Also, complete mortality was recorded with R. stricta extracts for adult of T. castanium only at the same concentration. On the other hand, extract of C. spinosa was more toxic to larvae (95%) than adult (90%) with the same concentration. The rest of plant extracts mortality was increased with increasing of concentrations. Medium lethal concentrations (LC50) against larvae for C. tuberculata, R. stricta and C. spinosa were 162.79, 201.25 and 210.64 ppm after 2 days and chronic (6 day) were 112.41, 129.91 and 133.08 ppm. As for adult, it were 231.22 , 286.99 and 307.68 ppm LC50s values after 2 days. After 6 days it was 126.47, 137.14 and 142.54 ppm LC50s, respectively. Other plant extracts were less toxic to larvae and adult of red flour beetle. Moreover, R. sricta, C. tuberculata and C. spinosa exhibited high repellency 100%, 90.08% and 82.54 % at concentration of 800 ppm against T. castanium adult. The application of these plant extracts may be promising in protecting of stored products against the attack of T. castanium specially extracts of C. tuberculata, R. stricta. and C. spinosa

Two field experiments were carried out during the two successive summer seasons of 2008 and 2009 at a newly reclaimed area, at Sadat city, of the Environmental Studies and Research Institute Farm, Minufiya University, Minufiya Governorate, Egypt. This study was conducted in order to assess the effects of different levels of both potassium sulphate fertilizer (0.0; 50; 100; 150 and 200 Kg/fed.) and potassium humate foliar applications (11% K2O) rates, i. e. 0.0, 0.5, 1.0 and 1.5%; as well as their interactions on the vegetative growth, yield and its components, tuber characteristics and tuber quality attributes of sweet potato crop. Potassium sulphate fertilizer affected significantly most studied traits. Generally, the increased potassium sulphate fertilization levels, from zero up to 200 Kg/fed., enhanced vegetative growth and, gradually, increased tuber root yield. The obtained results indicated that 200 Kg potassium sulphate fertilizer/fed. was the best level to increase total tuber yield. A similar trend was reached by spraying K-humate levels. Increasing potassium humate concentration from 0.0% to 1.5% increased most of the studied characters. The combined application of K2SO4 fertilizer levels and K-humate sprays reflected clear interaction effects. Tuber root yield reflected an increase of 10% - 15% by adding 200 Kg K2SO4/fed. combined with 1.5% K-humate compared with the control treatment (200 Kg K2SO4/ fed. only) in the first and the second seasons of the study, respectively. Generally, this study recommended spraying sweet potato fields, fertilized with 150 Kg K2SO4, with potassium humate to produce the highest tuber yield with the best quality.

The present study was carried out during 2007 and 2008 seasons on fruits of the newly introduced plum cvs. Celebration and Sapphire (from South Africa) in comparison with the local cv. Santa Rosa. The fruits were stored at 0°C and 85 - 90 % relative humidity. The physio-chemical properties of the stored fruits were followed up in 4 days intervals during the storage period and a sample was transferred to 20°C for observation after 2, 4 and 6 days (shelf life sample to simulate the marketability period). Fruits cooled at 0˚C can be stored for 28 days with good firmness but they lost their firmness and became dull in shelf life store. Chilling injury (CI) symptoms as flesh browning, translucency and bleeding appeared in the last two cold storage intervals (24 and 28 days) when the fruits were transferred to 20˚C. During cold storage period at 0˚C, Celebration had the highest significant weight loss percentages. In all cvs., weight loss averages of shelf life fruits were less than 1 % after 2 days and Sapphire fruits had the lowest percentages of weight loss. After 8 days at 0˚C then storage at 20˚C, Sapphire cv. had the lowest firmness loss percent. After 16 days of cold storage, the three cvs. had good firmness values but when the fruits were transferred to 20˚C, those values decreased significantly after 2 and 4 days. After cold storage, fruits of Santa Rosa cv. lost the highest percent of soluble solids content (SSC) compared with Celebration and Sapphire fruits. For shelf life fruits, there were no significant changes in SSC for the three cvs. in most intervals. Celebration fruits had the lowest initial acidity values and during the first cold storage periods (4 and 8 days) the acidity values of all cvs. decreased slightly but they increased when the fruits were transferred to 20˚C. With the progress of cold storage, the fruits of the three cvs. had less acidity content compared with the initial values and those values declined during the subsequent shelf life period. Peel anthocyanin content of Santa Rosa fruits (red cv.) decreased with the advancing of cold storage while that content of Celebration fruits (red cv.) increased slightly. On the other hand, the yellow Sapphire cv. showed the greatest increase in peel anthocyanin content. Santa Rosa flesh had the highest initial content of anthocyanin compared with the other two cvs. The flesh anthocyanin contents increased during the first 12 days of cold storage then decreased with the advancing of cold storage. During cold storage, peroxidase (POD) activity of all cvs. decreased then increased again during the last intervals. There was general trend of decreasing POD activity in shelf life fruits of all cvs. in the first 12 days of the experiment then it increased during the last 16 days. On the other hand, Sapphire fruits significantly had the highest initial values of polyphenol oxidase (PPO) activity and those values decreased sharply by the end of cold storage period. Celebration and Santa Rosa cvs. showed contrast trend where the PPO activities showed an increasing trend with the progress of cold storage.

This investigation was carried out during 2007 and 2008 growing seasons on six years old Arabi-pomegranate trees, grown in sandy clay loamy soil in a private farm located at Alexandria-Matrouh road, to study the effect of different fertilizers i.e., minerals (Ammonium Sulphate, Potassium Sulphate and Calcium Super Phosphate) at rate of 100% or 50% of the recommended dose or organic (humic acid or compost solely) or their combinations on growth, fruit set, yield, fruit quality and leaf minerals content during both seasons of study. The obtained results showed that, vegetative growth, fruit set, yield as weight or number of fruits /tree as well as fruit quality (average fruit weight, diameter, length, TSS and anthocyanine) and leaf N content were, generally, improved under all treatments as compared with control in both seasons. While, slight effect on leaf P and K content were noticed. The studied treatments decreased juice acidity and did not significantly affect V.C. and tannins content in both seasons. The striking treatments 50% of the recommended rate of NPK + organic matter (compost or humic acid) were most effective in improving all parameters when compared with other treatments. It is worthy to note that, using 50% of the recommended rate of NPK + organic matter (compost at 25Kg/ tree or humic acid at 12.5 or 25g /tree) had a similar effect to the treatment 100% of the recommended rate of NPK solely. Hence, it could be concluded that fertilizing pomegranate trees with 50% of the recommended rate of NPK + humic acid at higher rate 25g/ tree is the promising treatment under the same condition of our study. Moreover, it reduced half the amount of the recommended mineral fertilizers as well as soil pollution. ust gave the highest rooting percent .The highest survival percentage after two months from transplanting was recorded from cuttings prepared and planted at August and November in both studied seasons. As a conclusion we can say that rooting of some olive cuttings under shaded Polyethylene tunnel consider the best method compared with the other methods because it do not need a very expensive equipments.

The future increase in water demands with therequired quantities and qualities is a serious challengein the Kingdom. Therefore, improving the irrigationnetwork is an essential goal for water conservationunder the local conditions nowadays.The Hassa Irrigation and Drainage Authority(HIDA) is one of the largest agricultural projects inthe Kingdom. It covers about 8000 ha. This projectstarted about thirty years ago. Since that time thewater was distributed to the farmers by siphoning thewater from the field canal to the farm with the floodirrigation as the most method adopted. Theconsequence of that was unwise use of water.The objectives of this research work are: toevaluate the bubbler irrigation and the traditionaltrickle irrigation system to be an alternative to the floodirrigation especially under palm trees, and to evaluate themoisture distributions under systems currently used.To achieve these objectives a number of filed studieswere conducted in typical farms in Al-Hassa Irrigationand Drainage Scheme, to evaluate irrigation efficiencyand to determine the effect of irrigation systems andwatering regimes on date palm production.Data indicated that reproductive growth of date palmswere significantly affected by irrigation systems (furrow,bubbler and drip irrigation). Drip irrigation significantlyincreased yield, while no response was obtained under thethree irrigation regimes during the study. Moreover, thedata indicated that date palm water requirement in aloamy sand soil in Al-Hassa, Saudi Arabia is 1013.4,1170.0 and 1407.0 m3/palm/year for drip, bubbler andfurrow irrigation systems respectively

The significance of this research is related to the importance of natural zeolite ore occurring within Al-Sis formations that contain admixed heterogeneous pyroclastic-sedimentary deposits of the Upper Pliocene, outcropping in three locations (Tell Mekehlat, Tell AL-Sis and Tell Om-thon). The importance of zeolite ore is related to its diverse uses in agricultural, industrial, environmental and medical fields, to its availability in huge economic amounts, as well as to its outcropping near the land surface, permitting hence simple exploitation and mining processes. The main objective of this study is to determine the chemical composition of major, trace and rare earth elements in selected 32 rock samples representing all divers lithological types of Al-Sis formations, and to clarify some geochemical correlations that exist among them. Comparison between the chemical content of major elements in the studied sedimentary and or igneous rock samples did not provide any indications that facilitate its classification into distinct rock groups. This is supported by the field observations, which in turn indicated that the composition of Al-Sis formations represents a random heterogeneous mixture of volcanic rocks with a variety of other sedimentary rocks of different origin and composition.
The high percentages of weighted water loss and carbon dioxide are positively and progressively correlated
either to the content of samples from the zeolite and clay mineral groups or to the calcareous minerals group. With the exception of scandium, often associated with the olivine mineral widespread in abundant amount in Al-Sis Formations, the relatively high proportions of trace elements such as nickel, chromium and vanadium, may be exchanged and replaced by Mg and Fe in the crystal structure of olivine, or by Fe in some metallic minerals like magnetite and ilmenite. The samples that show low chemical contents in trace incompatible elements of large ionic size, low ionic charge, such as Rb, Ba, Sr and Cs, the so-called lithophilic elements (LILE), which have the possibility to be replaced by alkali strong elements, such as potassium and sodium in the main feldspar minerals or in the group of calcium, sodium, potassium, and barium zeolite minerals. The elements of high charge incompatible elements (HFSE) did not show any relation. The high increase in average uranium content in studied samples could be attributed to high phosphate minerals such as apatite and monazite, widespread in low percentages within Al-Sis formations. Although the high contents of heavy chalcophilic elements, such as Pb, Sn, As, Zn, Cr, Cd and U, having toxic behaviors, compared with those of their average contents in the rocks of earth crust, still in acceptable limits for improving the fertility of agricultural soil, for desalination of agriculture and industrial water drainages or for treatment of sewage water sladges.
