Effect of Nitrogen Fertilization on the Productivity and Sensitivity of Two Sweet Sorghum Varieties to Pink Stem Borer (Sesamia cretica led.) Infestation
تاثیر التسمید الاوزتى على انتاجیة وحساسیة صنفین من الذرة الرفیعه السکریة للاصابة
Sesamia cretica بدودة القصب الکبیرة
Two field experiments were conducted at Agriculture Faculty farm of Demo (29°17ˋ N; 30°53ˋ E) El-Fayoum University, Egypt, during 2013 and 2014 to study the effect of three nitrogen rates, i.e. 80, 100 and 120 kg N/fed. on the damage cause by pink stem borer infestation [Sesamia cretica Lederer (Lepidoptera: Noctuidae)] under natural infestation, on stem characteristics, quality and yield traits. In addition to theoretical ethanol production of two sweet sorghum varieties (Brandes and Honey).
Data obtained revealed that: Brandes variety is more tolerant to pink stem borer attack which recorded less damage sings measured in this study by many damage expressions. Moreover, Brandes exhibited better productivity traits (stalk, juice, syrup, grain, forage and ethanol yields) as well as quality traits (TSS, sucrose, reducing sugars, Total fermentable sugars and purity).
The results also showed that application of the highest nitrogen rate (120 kg N/fed.) increased all borer infestation features, productivity and quality traits.
The interaction between both variables markedly affected most studied traits, but in general, Brandes variety fertilized by the highest N rate exhibited the higher productivity and quality traits and the lower damage signs or to some extend characterized as moderate tolerance to pink borer infestation.

الاستجابات الفسیولوجیه للنمو والمحصول لبعض أصناف الفول البلدى تحت کثافات نباتیه مختلفه
Two field experiments were conducted at Mallawi Agricultural Research Station, Minia Governorate during 2013/2014 and 2014/2015 seasons to study of some faba bean varieties (Giza 843, Giza 3, Giza 716, Nubarai 1and Sakha 3) under different plant densities 84.000 plants /fed. (spacing between rows 50 cm), 70.000 plants /fed.(spacing between rows 60 cm) and 60.000 plants /fed. (spacing between rows 70 cm) and plant distribution (sowing on one and two sides/row) on yield and yield components of faba bean. Results showed that faba bean cultivars varied highly significantly on plant height, weight, Number of pods/plant, 100-seed weight (g), Seed yield/plant and Seed yield (ardab/feddan), during the two growing seasons. The highest value of plant height, Number of pods/plant and Seed yield (12.93 pod and 11.18 ardab/fed.) was obtained by Giza 843 variety compared with the other varieties in both seasons. While Giza 716 produced the highest values of plant weight (62.13 and 62.5 g) in both seasons, respectively. The heaviest 100-seed weight (g) and Seed yield/plant were achieved by Nubarai 1 variety in the first and second seasons. Plant density had significant effect on plant height. In the first and second seasons 84000 plants/feddan recorded the tallest plants (101.01 and 101.25 cm, respectively). Concerning the plant distribution, planting on two sides/rows produced the heightSeed yield (9.88 and 8.43 ardab/fed.) in both seasons, respectively. Compared with the planting on one side /row.
Regarding to the first and second order interactions in both seasons the results showed that the differences in seeds yield per feddan were not significant.

إستجابة إنتاجیة ترکیبین وراثیین من الذرة الرفیعة الحبوب للسماد الحیوی والمعدنی
فی الأراضی حدیثة الاستصلاح
Two field experiments were conducted in the Agricultural Research Station at Arab El-Awamer, Assiut Governorate, during the two growing seasons of 2014 and 2015 to investigate the response of two grain sorghum genotypes productivity to bio- and nitrogen fertilizer in newly reclaimed soil. The randomized complete block design using split-split-plot with four replications was employed, where the genotypes (Hybrid 305 and Dorado i.e. G1 and G2) were allocated in the main plots, while nitrogen fertilizer rates (60, 90 and 120 kg N/fed i.e. N1, N2 and N3) were assigned in the sub-plots and bio-fertilizer (0, Microbin and Nitrobin i.e. B0, B1 and B2) were fixed in the sub-sub-plots. The grains of sorghum genotypes were sown on 13th and 17th June in the first and second seasons, respectively. The plot area was 12 m2 including 4 ridges of 60 cm apart with 4 m length.
The results could be summarized as the following:
- Hybrid 305 genotype surpassed the Dorado variety and gained the highest mean values of the plant height, panicle length, panicle weight and grain yield/fed, while the Dorado variety gave the highest mean values of panicle width and 1000 grain weight in both seasons.
- The all studied traits increased by increasing N fertilizer rates and the maximum values were achieved by the highest N fertilizer rate (120 kg N/fed.) in both seasons.
- The Microbin bio-fertilizer recorded the highest mean values for the all studied traits in both seasons, but Nitrobin bio-fertilizer recorded the heaviest 1000 grain in the 1st season only.
- The G1xN3 (Hybrid 305 x 120 kg N/fed.) interaction treatments gave the maximum values for panicle weight in both seasons and grain yield/fed. in the 2nd season, as well as G1xN2 (Hybrid 305 x 90 kg N/fed.) gave the maximum values for grain yield/fed. in the 1st season. Moreover, the maximum grain yield/fed. (18.89 and 14.62 ard.) were obtained by G1xB1 (Hybrid 305 x Microbin) interaction treatments in the 1st and 2nd seasons, respectively.
- In general, the first order interaction; N1xB0 (60 kg N/fed. x without bio-fertilizer) interaction treatment gave the lowest mean values for the all studied traits in both seasons.
- The highest mean values for panicle weight and grain yield/fed. were recorded by G1xN3xB0 (Hybrid 305 x 120 kg N/fed. x without bio-fertilizer) and G1xN2xB1 (Hybrid 305 x 90 kg N/fed. x Microbin) interaction treatments in the 1st season, respectively.

تأثیر المعاملات الحراریة على توزیع النیتروجین فی اللبن البقرى والجاموسی
Cow and buffalo’s skim milk were heated at 70-90°C instantly in order to study its effect on nitrogen distribution and contrary on whey protein denaturation. The obtained results showed that the cow skim milk had higher values of WPN, WN/TN & WPN/TN and lower values of TN, CN, NPN, C No., NPN/TN & WP denaturation than that of buffalo’s skim milk in all treatments, respectively. The raw skim milk had higher values of WN, WPN, WN/TN & WPN/TN and lower values of TN, CN, NPN& C No. than that of heated skim milk in all treatments, respectively. In addition, the clotted cow milk had higher values of RCT and SY and lower value of CF than that of clotted buffalo’s skim milk in all treatments. The increase of heat treatment of milk cause an increase of RCT and decrease of CF and SY in all treatments. Moreover, the control samples had higher and lower values of RCT and higher CF and SY than that of heated milk in all treatments. The decreases of pH values from 6.4 to 6.0 cause an increase of CF and then decrease with decreasing the pH up to 5.6 in clotted cow skim milk, while there were decreases of CF in clotted buffalo’s skim milk up to pH 5.6 in all treatments.

Nutritional Value of Farmed and Wild Quail Meats
القیمة الغذائیه للحوم سمان المزارع والسمان البرى
The aim of this study was to determine the proximate chemical composition, mineral content, amino acid composition and fatty acids profile in the breast meat of farmed young (6weeks) and spent (8months) Japanese quails as well as wild quail to compare the nutritional value of the meat. The results indicated an increment in protein, fat and caloric value by increasing the age of farmed birds. The wild quails meat was higher in protein, Fe, Zn levels compared to the farmed quail meats. The essential amino acids content recorded 37.09,36.05and39.30 g/100g protein for young, spent and wild quail breast meat; respectively. The predominant fatty acids in farmed Japanese quail meat were oleic, linoleic, palmitic and stearic whereas, it were oleic, vaccinic, palmitic and stearic in wild quail meat. Oleic acid, constituted more than one-third of fatty acids content of breast meat of all studied quail meat types. Quail meat should be taken into consideration due to the high oleic acid content which, associated with lowering the risk of cardiovascular disease.

Effect of Osmotic Dehydration as Apre-treatment on some Characteristics of Ventilated Hot Air Drying (VHD) Kiwifruit Slices
تأثیر التجفیف الاسموزى کمعامله مبدئیه على بعض خصائص شرائح فاکهة الکیوى المجففة بفرن التهویة بالهواء الساخن
Food dehydration of fruits is one of the most challenging processes in food technology. In order to optimize the quality of dehydrated fruits novel dry conservation procedures should be developed. Where ventilated hot air dryers’(VHD) produces poor fruit quality. So, different methods were applied to decrease the drawbacks of traditional methods. Kiwifruit slices submitted to steaming and osmotic dehydration (OD) in 60% sucrose solution as pre-treatment followed by VHD was studied. Results revealed that weight reduction (WR), water loss (WL) and solid gain (SG) of kiwifruit were significantly increased as extend of immersion period. Weight reduction (WR) was found to be lower than water loss (WL) during OD. On the other hand, WL was higher than that of SG. Steaming and/or OD as pre-treatment for kiwifruit drying increases the membrane permeability. Moreover, steaming process releases the trapped air from the kiwifruit tissue. Thus increase both water loss (WL) and dehydration efficiency index (DEI). Contrary, decrease moisture content (MC) in the final product. Steaming process is more pronouncing effect than that of OD. Rehydration capacity (RC) of dried kiwifruit slices improves by OD using osmotic solution (60% sucrose) at 40°C for 2 hrsas pre-treatment while steaming process has no remarkable effect

This study was conducted during 2014 and 2015 seasons to test the effect of different concentrations (0.05 & 0.1 & 0.2%) and frequencies of application (twice or thrice) of potassium silicate on fruiting of Navel orange tree s grown under Bani-Suef environmental conditions.
Carrying out two or three sprays of potassium silicate at 0.05 to 0.2% had material promotion on all vegetative growth aspects, leaf pigments and nutrients, fruit setting %, yield and both physical and chemical characteristics of the fruits over the check treatment. The promotion was related to the increase in both concentrations and frequencies of application of potassium silicate. All the investigated characteristics were unaffected by increasing concentrations of potassium silicate from 0.1 to 0.2% and frequencies of application from twice to thrice.
Carrying out two sprays of potassium silicate at 0.1% on the middle of March and April gave the best results with regard to yield and fruit quality of Navel orange trees grown under Bani-Suef conditions.

Effect of GA3 and Lemongrass Oil Spraying on Fruiting of Ruby Seedless Grapevines
تأثیر رش حمض الجبریلیک وزیت حشیشة اللیمون علی إثمار شجیرات العنب الروبی اللابذری
This investigation was conducted during the two successive seasons of 2015 and 2016 at the Experimental Orchard Faculty of Agriculture, Assiut University, Egypt, to compare the effects of GA3 and lemongrass oil spraying on fruiting of Ruby Seedless grapevines.
GA3 spraying was applied twice, once at 5 or 7.5 ppm at full bloom and the second, 30 ppm when the berry size about 5-6 mm, whereas, lemongrass oil spraying was applied at 0.5, 1 or 1.5% at the same previous dates.
The results obtained could be summarized under the following main points: lemongrass oil twice spraying significantly decreased the berry set percentage, cluster weight and yield/vine and consequently significantly decreased the cluster compactness coefficient compared to the unsprayed ones. On other hand, GA3 twice spraying significantly decreased the berry set percentage and insignificantly decreased the cluster weight and yield/vine, as well as significantly decreased the cluster compactness compared to unsprayed ones. No significant differences in these traits due to lemongrass oil spray at 1 or 1.5% as well as GA3 at 5 or 7.5 ppm.
Lemongrass oil significantly improved the berry quality in terms of berry weight, total soluble solids and anthocyanin contents, whereas GA3 significantly increased the berry weight and significantly decreased anthocyanin content.
From this study, it is clear that lemongrass oil twice spray at 1% improve the grapevines production and overcome the adverse effects of GA3 used at high concentration.

This study was carried out at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt, to study the effect of GA3, calcium chloride and vapor guard spraying on fruiting of Manfalouty pomegranate during 2014 and 2015 seasons. The experiment was set up in a complete randomized block design with three replicates, one tree per each.
GA3, calcium chloride and vapor guard spraying significantly increased the yield/tree compared to unsprayed ones. GA3 spraying gave the highest yield followed by calcium chloride. On the other hand, all treatments significantly decreased the fruit cracking percentage compared to unsprayed ones. The least fruit cracking was recorded due to calcium chloride spraying.
All treatments significantly increased fruit weight and fruit dimensions as well as aril percentage and juice contents compared to unsprayed ones. Moreover, calcium chloride and vapor guard significantly improved the fruit chemical constituents, whereas, GA3 spraying decreased the chemical fruit constituents compared to unsprayed ones.
It could be concluded that spraying Manfalouty pomegranate trees with calcium chloride at 40 or 80 ml/L at 1st July was necessary to get high yield, reduce the fruit cracking percentage and improve fruit quality.

تأثیر إستخدام نظم الری المختلفة وتقنیة الری النبضی والسلیکون على النمو الخضری والمحصول والعلاقات المائیة للذرة الشامیة تحت ظروف توشکى المناخیة
Field experiments were carried out at the experimental farm of Water Studies and Research Complex (WSRC) Station, National Water Research Center, Toshka – Abu Simbel city, Egypt during the two summer seasons of 2015 and 2016 to study the effect of three irrigation methods including new types of micro irrigation, pulse irrigation technique and silicon application on water relations of maize (Giza - 358, variety) as well as yield and yield components. The experiments were laid out in split plots design with three replicates and consisted of three treatments. The results indicated that the effect of pulse irrigation technique on water use efficiency were larger than the effect of irrigation system and silicon application, the mean values of water use efficiency were (0.56, 0.52 and 0.52 kg/m3) for pulse irrigation technique, irrigation system and silicon application, respectively. Also the results showed that grains yield (ton/fed) was increased for combined irrigation system and pulse irrigation technique which had been recorded (1.4 ton/fed)while the mean values of silicon application were (1.3 ton/fed). Finally, under the current experimental conditions, it could be concluded that pulse technique and silicon application under combination irrigation system is suitable under Toshka climatic conditionsandcaused significant increases in WUE and grain yield.

سلوک 5 أصناف من البامیا المنزرعة فى مواعید مختلفة تحت ظروف أسیوط
A field experiment was conducted to evaluate the response of okra sowing date and variety on growth and yield at the Experimental Farm of Faculty of Agriculture, Assiut University, Assiut, Egypt, during 2011 and 2012seasons. Two sowing dates i.e. April 15 and May 15 and five varieties i.e. BaladyAssiut, BaladyQena, Emerald, Golden Coast and PusaSawani were studied. From the results it was noticed that the fruit number and fruit yield significantly affected by sowing date and variety. In case of sowing on 15thApril, the heighest fruits yield was (8.577 and 8.146 ton/feddan) in both seasons. However 15th May sowing date produced the lowest fruits yield (4.227 and 4.005ton/ feddan). PusaSawani cv produced the highest yield of okra in two sowing dates (12.341, 6.632 and 11.904, 6.365 ton/feddan) in both seasons, respectively. Determination of optimum sowing date is considered an important to have optimum yields. Results shown that varities, Golden Coast and PusaSawani produced higher fruits yield on 15th May than BaladyQena cv sown on 15th April. The interaction between varieties and sowing date was significant in both seasons for plant height, number and weight of green pods/plant and total green yield/fed.

تأثیر تحمیل الفجل واللفت مع الفول على النمو والمحصول تحت ظروف اسیوط
The current study evaluates the efficiencies of faba bean, turnip and radish grown as sole crops and when radish and turnip intercropped with faba bean on growth, yield and quality characteristics. A field experiment was carried out during 2014- 2015 and 2015-2016 seasons at the Experimental Farm of Faculty of Agriculture, Assiut University, Assiut, Egypt. Intercropping of turnip and radish with faba bean resulted in significantly higher yields of both crops (turnip and radish) as compared with their sole cropping. All other characteristics (plant growth and yield components) of all the two crops which indicate yielding efficiency enhansment as a result of intercropping. Analysis of intercropping treatments revealed that faba bean intercropping with turnip increased the yield of turnip by (50.87- 51.13%)when planting were done in sprinkle and by(18.18-19.35%) when planting were done in hills as compared with sole crops in the first and second seasons respectively. However intercropping radish with faba bean resulted in the highest yield in radish by (66.74- 67.48%) when planting were done in sprinkle and by (75.27-81.55%) when planting were done in hills as compared with sole crops in the first and second season respectively.Yield of faba bean increased when intercropped with radish by(9.82-13.16%) rather than intercropping with turnip or sole cropping. Land equivalent ratio (LER) of faba bean-radish intercropping was, on average,2.7 for both years.With regard to faba bean- turnip intercropping, (LER) was, on average, 2.6 for both years.

An Economic Study of the Summer Sorghum Crop- Assiut Governorate
دراسة إقتصادیة لمحصول الذرة الرفیعة الصیفیة بمحافظة أسیوط
Sorghum is considered one of the most important crops in Egypt, it is considered the third grain summer crop, after rice and corn according to the space of the cultivated area. It is also used in making bread and fodder for animals and poultry. The research is aiming at recognizing the production possibilities of sorghum in Assiut Governorate via estimating the function of production and the cost, also, estimating the effect of Types Technology on the transmitting of the production function of the crop and also estimating the loss from the crop and the consequent effects. The study showed the following results:
By estimating the functions of the crops production of the three productive groups and the total of the research sample, the research shows the stability of the morality statistics of the complete pattern and the provisional pattern at level 0.01.
For the first owners group, the stability of the morality statistics of the independent factors (numbers of labors S2, seeds quality S4, the quantity of fertilizers, number of nitrate fertilizers units S6) and the flexibility of the total productivity reached 1.07 it indicates the increase of the revenue on capacity. The results of the second owners group refers to the stability of the moral effect of the independent factors which is the cultivated land S1. The number of labors hands, number of automatic labor hours (S3) and the quantity of the fertilizers (S5). The total of research sample refers to the stability of the moral effect of the independent factors which are the cultivated land (S1), the number of the labor hands (S2), the quantity of the seed (S4), the number of the nitrate fertilizers (S6); the flexibility of the total production is 1.086 and it refers to the increase in the revenue capacity.
By evaluating the production cost functions of the summer sorghum, the research results indicate to the stability of the statistical morality of the three owners groups, and that the total research sample is at the level of 0.01. According to the first owners group, the optimum volume of the production amounted 17.17 Ardeb/Feddan, the maximum volume of the profit is about 306.77 L.E./Ardeb, and the economical efficiency is about 0.96. Meanwhile, the previous economical derivatives of cost functions of the second owners group amounted 17.83 Ardeb, 18.75 Ardeb, 0.95, 276.04, respectively, and the third owners group amounted 18.28 Ardeb, 19.40 Ardeb, 262.64 L.E./Ardeb, 0.980 respectively. As regards the total research sample, the optimum volume of production amounted 19.56 Ardeb, about 20.68 Ardeb for the maximum volume, about 274.83 L.E. and 0.996 for both of the economical price and efficiency.
The study recommends the following:
* The necessity of replacing Horus products with the other products and generalizing it on the level of the governorate.
* Aiming at reducing the crop loss in the various marketing operations and this is for rationalizing the water consumption and reducing costs.
