The present investigation was carried out to evaluate the efficiency of two biopreparations of Bacillus thuringensis (MYX104 and MYX833) on certain biological parameters of the potato tuber moth Phthorimaea operculella (Zeller) under laboratory conditions.The results cleared that the tested biopreparation had a delayed effect on the fitness components of the insect. In general, all the treatments achieved a significant shortened moth longevity of both sexes, prolongation of larval and pupal durations, severe reduction in the number of resulted pupae, great increase of the rate of malformed pupae, and sharp decrease of the rate of emerged moths according to the tested concentration of each biopreparation. Moreover, the consequently reared generations after parent's one treatment that indicated so lowered viability of developing individuals and decreased numbers of emerged unviable weak and sterile moths followed by final termination of the life cycle, which revealed as distinct failure of (F3) development due to the former treatment of (P) one with the lowest tested concentration of each of MYX104 & MYX833 (25 ppm). That failure could be attributed to the cumulative effect of induced recessive lethal genes in both influenced sexes along the extended period of the following generations post- treatment of parents one, causing apparent drastic effects, which appeared at the beginning of (F3). The results also proved that MYX104 was more effective than MYX833 on the investigated parameters of the fitness component of the potato tuber moth .

The activity of methanolic plant extracts from Rhazya stricta Cleome paradoxa and Heliotrobium bacciferum has been investigated towards larval mortality and development of Culex pipiens L. Plant extracts exhibited variable biological activity. The greatest activity was observed for R stricta which showed LC 50s of 154.2 and 84.2 ppm, respectively after 2 and 10 days of exposure. Percentage of larval mortality was 95.33% in the treatment with extracts of R stricta and 84.8% in C. paradoxa. Egg hatchability was significantly reduced in R stricta concentrations. All concentrations of the plant extracts from R stricta, C. paradoxa (200 ppm and above) and H. bacciferum (400ppm and above) caused significantly high hindrance to the subsequent larval development and reduced both pupation and adult emergence. Drastic retardation of development was shown by R stricta extracts, where only 19.3% and 9 % of the larval managed to reach pupal and adult stages, respectively, when reared in very low concentration (100 ppm) of the extract. However, C.paradoxa and H. bacciferum were more effective at higher concentrations. Application of such plant extracts to mosquito breeding sites may have great practical importance in relation to non-synthetic chemical control of these serious disease vectors.

Three field experiments were carried out during two successive seasons of 2005/06 and 2006/07 at Kafr El-Sheikh Governorate to study the effect of N, Kfertilization on wheat yield under three levels of soil salinity. Grain and straw yield of wheat (Triticum aestivum) cv.Sakha 94 had significantly increased with increasing of N application up to 140 kg fed.-1under different soil salinity. The yield was also increased with application of 50kgfed.-1K2O. Results indicated that there were highly significantly effects on grain and straw yield of wheat during the two growing seasons due to the interaction between N-K where the grain yield were recorded the highest mean values (23.95, 24.01, 20.86, 20.95 and 19.05, 19.60) by N application of 140Kg fed.-1 plus 50Kg fed.-1 K2O for normal soil, medium saline soil and high saline sodic soil in the two growing seasons, respectively. The straw yield were 4.798, 4.787 ton fed.-1, 4.084, 4.143 ton fed.-1 and 3.363, 3.387 ton fed.-1 by nitrogen rate of 140Kg fed.-1 plus 50Kg K2O fed.-1 for normal soil, medium saline soil and high saline sodic soil in the two growing seasons, respectively. The N-uptake and recovery by wheat yield was increased with increasing application of nitrogen, but decreased as soil salinity increased, and increased by potassium application. The response of nitrogen application reached to 80kgN/Fed. in normal soil but by increasing N application up to 120kg N/Fed. in medium and high saline soils The highest relative variations of N recovery were +18.2%, +12.4% and +17.1% were recorded by application of N 40 in normal soil and N 120 in medium saline soil and high saline sodic soil, respectively. Nitrogen use efficiency (NUE) by wheat yield was decreased with increasing both application of nitrogen and soil salinity but improved by application of 50 kg fed.-1 K2O, with relative variations of 20.4% and 11.9 % with N80 for normal soil and medium saline soil, respectively. To achieve the highest yield of wheat (Triticum aestivum) cv.Sakha 94, it is recommended to apply nitrogen at the rate of 120kgN/Fed. And 50 kg fed.-1 K2O plus 22 kg P2O5/fed. in non saline soil and application of N at the rate of 140kgN/Fed.and 50 kg fed.-1 K2O plus 22 kg P2O5/fed.in medium saline and highly saline sodic soil, respectively.

The present work was carried out during the two successive seasons 2008and 2009 in the experimental station of soil salinity and alkalinity laboratory, Alex., to study the effect of inoculation with the biofertilizers [Nitrobine+Phosphorein(NP) 1:1 w/w] at rates 0.0,2.5,5and 10g/plant and salinized water ( EC,2, 4 and 8 dSm-1 ) and their combinations on the growth, yield and chemical content of leaves and sepales of Hibiscus sabdariffa, L. plants. In addition soil EC, pH , SAR and NPK availability were determined. The results indicated that increasing rates of the biofertilizers Nitrobine+Phosphorein (NP) resulted in considerable significant increases in all growth parameters [plant height (cm), number of branches / plant, number of leaves, dry weight of leaves / plant (g)] and yield [number of fruits / plant, fresh and dry weights of fruits / plant(g)]. Anthocyanine pigments and vitamin C and total chlorophyll content and mineral content (N,P and K %) were increased. The highest increase in these characters were obtained from adding the biofertilizers at rate 10g/plant combined with EC,2dSm-1 saline water irrigation. Also, the increment applications of biofertilizers(NP) at any levels of irrigation water salinity imposed considerable reduction in soil pH, EC and SAR. In the contrary, soil available N,P and Kwere progressively increased with increasing application rates of biofertilizers(NP) at 5 and/or 10g/plant across salinity treatment. The highest value were performed with 10g/plant biofertilizers(NP) with saline water level of EC,2dSm-1

Low quality of sugar beet roots is one of the problems which face expanding in agriculture of sugar beet in Middle Egypt; especially El-Minia Governorate .This trial was conducted at Mallawi Agric.Res. Station ,El-Minia, Egypt, during 2008/2009 and 2009/2010 seasons to determine the optimal level of boron and nitrogen fertilizer to obtain the highest yield and quality of sugar beet . Split plot design with four replications was used. Nitrogen fertilizer levels i.e. 80, 100 and 120 kg/fed were arranged in the main plots. Boron, as boric acid, was foliar sprayed at 0.00, 0.05 and 0.10 % and allocated in the sub plots. Foliar applications of boron were applied at 80 days after planting. The obtained results revealed that boron and nitrogen fertilizer levels had a significant effect on vegetative traits, i.e. root length and diameter (cm), quality characteristics (pol%, Na, K, a- N contents, sugar recovery % and quality index) and productivity parameters of sugar beet (root and sugar yields ton/fed) in the two growing seasons and the combined. Applying fertilization of sugar beet by 100 kg N /fed with foliar application of boron with 0.10 %( as boric acid) is recommended under Middle Egypt conditions (El-Minia Governorate conditions) because it gave the hightest value of recoverable sugar yield (4.39 ton/ fed) of sugar beet compared with the other.

The present study aimed to assess and to evaluate some of the sustainable and safe measures against Culex pipiens mosquito larva that can be implemented in areas at risk of contacting elephantiasis. The joint toxic action of these control measures was also studied. Data showed that Deltamethrin (LC50=0.021ppm) was more toxic than Bacillus thurengiensis var. israelensis, diflubenzuron, emamectin benzoate and azadiractin by 2.0, 491.42, 59.0 and 143.8 fold, respectively, after 24hr. Also, after 48hr Deltamethrin (LC50 = 0.004 ppm) was 4.0, 1102.5, 25 and 232.5 times more toxic than Vectobac G, diflubenzuron, emamectin benzoate and azadiractin, respectively, after 48hr. After 72hr the toxicity of Deltamethrin (LC50=0.003 ppm) was 3.0, 206.66, 23.33, 246.66 fold more toxic than B.t.i., diflubenzuron, emamectin benzoate and azadiractin, respectively. Toxicity of Beauveria bassiana was very low compared with all the tested control measures with LC50 value 1.85ml/L after 72hr of exposure. Data of joint toxic action revealed that, all mixtures of Beauveria bassiana with diflubenzuron and all mixtures of diflubenzuron with azadiractin resulted in antagonistic effects. Approximately, all other binary mixtures resulted in potentiating effects. The highest potentiating effect was obtained when the mixture of LC12.5 B.t.i. + LC12.5 Deltamethrin was used. Finally, the use of some binary mixtures of the tested control measures can achieve better control, reduce control cost and induce lesser environmental pollution.

Data showed that Deltamethrin (LC50=0.021ppm) was more toxic than Bacillus thurengiensis var. israelensis, diflubenzuron, emamectin benzoate and azadiractin by 2.0, 491.42, 59.0 and 143.8 fold, respectively, after 24hr. Also, after 48hr Deltamethrin (LC50 = 0.004 ppm) was 4.0, 1102.5, 25 and 232.5 times more toxic than Vectobac G, diflubenzuron, emamectin benzoate and azadiractin, respectively, after 48hr. After 72hr the toxicity of Deltamethrin (LC50=0.003 ppm) was 3.0, 206.66, 23.33, 246.66 fold more toxic than B.t.i., diflubenzuron, emamectin benzoate and azadiractin, respectively. Toxicity of Beauveria bassiana was very low compared with all the tested control measures with LC50 value 1.85ml/L after 72hr of exposure. Data of joint toxic action revealed that, all mixtures of Beauveria bassiana with diflubenzuron and all mixtures of diflubenzuron with azadiractin resulted in antagonistic effects. Approximately, all other binary mixtures resulted in potentiating effects. The highest potentiating effect was obtained when the mixture of LC12.5 B.t.i. + LC12.5 Deltamethrin was used. Finally, the use of some binary mixtures of the tested control measures can achieve better control, reduce control cost and induce lesser environmental pollution.

A field experiment was conducted during 2008 and 2009 growing seasons in sandy soil of Bustan area, Tawfik EL- Hakem village, Behera governorate, Egypt. The objective of this study was to evaluate the influences of foliar application with mixture of potassium, calcium and magnesium on fruit set, fruit growth rate, fruit splitting, yield and fruit quality of Washington Navel orange trees. The tested variables were:T1: Control (Only Sprayed with tap water).T2, T3 and T4: Trees sprayed with 300ppm liquid potassium plus 100 ppm chelated calcium plus 20 ppm magnesium sprayed once; on May, 10, twice; on May, 10 and June, 10 and thrice, on May, 10, June, 10 and July, 10 respectively. T5, T6 and T7: Trees sprayed with 600 ppm liquid potassium plus 200ppm chelated calcium plus 40ppm magnesium also sprayed at the same dates mentioned above. Mature (6 years old) of Washington Navel orange budded on sour orange rootstock and spaced at 5m apart were used. Results indicated that spraying Washington navel orange trees with potassium, calcium and magnesium once, twice or thrice with two concentrations resulted in a higher number of fruit set / branch, number of fruits/ tree and yield. Different spraying treatments increased fruit growth rates, fruit weight, diameter, rind thickness and juice volume. Fruit acidity and T.S.S. was increased only in one season, while,fruit length and Vitamin C content was not affected. The results also showed a marked decrease in fruit splitting percentage. Different foliar applications increased potassium, calcium and magnesium in the leaves.

To study effect of mineral and bio nitrogen fertilizers comparing to traditional nitrogen fertilization on growth, flowering, fruit set %, productivity and leaf and fruit mineral, total carbohydrates content and leaf total chlorophyll. Data revealed that T3 (2¼ kg amonium Sulphate + 1 kg super phosphate + 2 kg potassium Sulphate + 150 gm nutrobine) significantly increased number of new shoots in both seasons of study while T2 (3 kg amonium Sulphate + 1kg super phosphate + 2 kg potassium Sulphate + 75 gm nutrobine), T3 (2¼ kg amonium Sulphate + 1 kg superphosphate + 2 kg potassium Sulphate + 150 gm nutrobine) T4 (1.5 kg amonium Sulphate + 1 kg super phosphate + 2 kg potassium Sulphate + 225 gm nutrobine) significant increased in average shoot length ,leaf total chlorophyll, number of flowers, number of fruits and fruit set %in both seasons of study compared with control. T4 gave the best result in yield of both seasons of study. T3, T4 and T5 (¾ kg amonium Sulphate + 1 kg super phosphate + 2 kg potassium Sulphate + 300 gm nutrobine) increased fruit weight in first season only, while all treatments did not effected the fruit length, width and firmness in both seasons of study T3, T4 improved pulp thickness, while T3 caused a significant increase in fruit T.S.S. in first season. Fruit acidity was not affected with all treatments in both seasons of study. T4 significantly increased V.C. content in both seasons of study. T2, T3 and T4 gave the highest concentration of N content in leaves in both seasons while T3 in first season and T2, T3 and T4 in second season gave a significant increase in P leaf content. All treatments increased leaf K content in both seasons of study. There was a significant increases in fruit nitrogen content with T3, T4 treatmenst due to application of biofertilizers in 2007 and 2008. While phosphorus and potassium contents were not affected with all treatments in both seasons of study.Application of the combination of N.P.K. and nitrobein improved production and fruit quality of seedy guava. So, we can recommend using biofertilizers with decreasing mineral nitrogen 50-75% to save costs and keep environment unpolluted.

This study aimed to measuring coefficient of food security of sugar during the period 1990-2008 in addition to the estimation of quantity and value of imports necessary to achieve different levels of food security for refined sugar in 2015. This study is based on economic equations and quantitative economic analysis. The results of this study include:
1- The strategic stock of sugar is 312.2 thousand tons, enough for domestic consumption for five months only. In the light of the strategic stock and the average domestic consumption of sugar amounting 552.45 thousand tons, the estimated coefficient of food security is 0.56 in the period 1990-2008.
2- Imports and domestic consumption are the most important determinants of the coefficient of food security for refined sugar. Under the policy to achieve the full level the coefficient of food security,
it requires the importation of a quantity of refined sugar amounting to 1.36 million tons, at the value 993 million Dollars in 2015.
3- This study recommends the need to maintain the food security of refined sugar, through the strategic stock, enough domestic consumption for a period not less than six months, The adoption of several policies including the following: (A) rationalizing the domestic consumption of refined sugar in both urban and rural Regions so as not to increase the consumption needs than the estimated values, (B) expansion of the import of refined sugar to achieve different levels of the Coefficient of food security in 2015.

Women may suffer from various kinds of symptoms during menopause. These may include physical and psychological changes; osteoporosis is the major health problem in this phase in addition to cardiovascular disease. This research aimed to study the effect of soy flour Protein on some biological parameters in ovariectomized rats including density and structure of bones, estrogen and thyroxin FSH,LH, PRO,TSH hormone. The study was performed on female Albino rats that divided in to six groups, one group was sham operated and fed standard diet. The other five groups were the ovarictomized one group fed on the standard diet, while remaining four group were fed with soy flour in percents of (25,50,75,100 %) of meal protein.
After nine weeks femour bone structure and density . The body weights of food intake, Food Efficiency Ratio (FER), Protein Efficiency Ratio (PER), internal body organs were also measured Alkaline phosphates enzyme, estrogen and FSH, LH, TSH, Prolactine hormones were determined.. The results showed that soy flour consumption improved the nutritional status FER, PER, bone density, bone structure and decreased in alkaline phosphates enzyme level, but increased estrogen. Therefore, the researcher recommends postmenopausal women to eat soy flour, soybeans and soy products which are rich in isoflavons that improve estrogen hormone level, hence reduces osteoporosis, heart and cardiovascular diseases risks.
Women may suffer from various kinds of symptoms during menopause. These may include physical and psychological changes; osteoporosis is the major health problem in this phase in addition to cardiovascular disease. This research aimed to study the effect of soy flour Protein on some biological parameters in ovariectomized rats including density and structure of bones, estrogen and thyroxin FSH,LH, PRO,TSH hormone. The study was performed on female Albino rats that divided in to six groups, one group was sham operated and fed standard diet. The other five groups were the ovarictomized one group fed on the standard diet, while remaining four group were fed with soy flour in percents of (25,50,75,100 %) of meal protein.
After nine weeks femour bone structure and density . The body weights of food intake, Food Efficiency Ratio (FER), Protein Efficiency Ratio (PER), internal body organs were also measured Alkaline phosphates enzyme, estrogen and FSH, LH, TSH, Prolactine hormones were determined.. The results showed that soy flour consumption improved the nutritional status FER, PER, bone density, bone structure and decreased in alkaline phosphates enzyme level, but increased estrogen. Therefore, the researcher recommends postmenopausal women to eat soy flour, soybeans and soy products which are rich in isoflavons that improve estrogen hormone level, hence reduces osteoporosis, heart and cardiovascular diseases risks.

Woman meets various kinds of symptoms during menopause, it may include physical and psychological changes,whrle osteoporosis is the major health problem in this phase in addition to cardiovascular disease. This research aimed to study the effect of soy flour on some biological parameters in ovariectomized rats. including blood lipid, blood pictures and differential count of lymphocytes. The study was performed on female Albino rats that divided into six groups, one group was sham operated and fed standard diet, the other five groups were the ovarictomized, one group was fed on the standard diet, while the remaining four groups were fed with soy flour in percents of (25,50,75,100 %) of meal protein.After eight weeks the body weight of food intake , Food Efficiency Ratio (FER), Protein Efficiency Ratio(PER), internal body organs were also measured and blood lipid and, CBC, and differential count of lymphocyte ware determined . The results showed that soya flour consumption improved the nutritional status, FER,PER, blood lipids, and increased hemoglobin levels. Therefore, the researcger recommends postmenopausal women to eat soy flour ,soybeans and soy products which is rich in isoflavons that improve estrogen hormone level, hence reduces osteoporosis, heart and cardiovascular diseases risks
