This study was conducted at El-Ghorieb Exp. Farm, Assiut University, Assiut,Egypt, during 2010/2011 and 2011/2012 seasons to investigate the effect ofpotassium fertilization (48 and 72 kg K2O fed.-1) and the foliar spray with threezinc chelate levels zero, 75, and 150 mg l-1 as Zn-EDTA (15% Zn) on yield andquality as well as Fe, Mn and Zn contents of sugar beet plants grown on a calcareoussandy soil.- All plant characteristics and quality traits of sugar beet i.e., top and rootfresh and dry weights, sucrose content, sugar recovery, recoverable sugar yield,as well as Fe, Mn and Zn contents were significantly increased by increasing theK level from 48 to 72 kg K2O fed.-1 in both seasons.- Increasing the potassium level caused an increase in the sucrose percentage.Moreover, a remarkable increase in the recoverable sugar percentage wasobserved as K level increased. Potassium fertilization showed a significantly increaseon sugar beet yields at 48 kg N fed.-1 level as well as 72 kg K2O fed.-1 fortop yield and recoverable sugar yield.- With regard to zinc foliar application, significant decreases on impuritiesand increases on sugar loss to molasses and sucrose percentage were observed. Italso had an insignificant effect on the recoverable sugar percentage. In mostcases, increasing Zn level up to 150 mg l-1 significantly increased the sugar beetyields fed.-1- Potassium fertilization x zinc foliar application interaction had a significanteffect on Na content in beet roots in both seasons. Moreover, significant effectswere observed only on K content in beet roots and sugar losses to molassesin the first season as well as top yield fed.-1 in the second season. It could be concludedthat application of the K fertilization at 72 kg K2O fed.-1 along with thefoliar application of zinc had a positive effect in increasing all growth traits ofsugar beet

Experimental work was done in Al-Wady El-Assiuty, Expt. Farm of AssiutUniversity, Assiut, Egypt during 2010/2011 and 2011/2012 seasons to investigatethe effect of boron concentration (zero, 50 and 100 ppm) and different applicationtime (35, 70 and 105 days after planting, DAP) on yield and quality traits ofsugar beet plant grown in newly reclaimed soil conditions. Randomized completeblock design (RCBD) using split-plot with three replications was used. The obtainedresults revealed that:-Yield and quality traits of sugar beet i.e., top and root fresh and dryweights, sucrose %, sugar recovery % and K concentration in root were significantlyincreased by high boron concentration compared with control in both seasons.-Boron spraying time had a significantly positive effect on yield and qualitytraits of sugar beet, however it's had any considerable effect on tops dry weight(ton fed.-1), sugar loss %, sugar loss yield (ton fed.-1) and some impurities componentsconcentration in both seasons.-There were significantly effects due to the interaction between concentrationand spray time of boron on yield and quality traits of sugar beet crop exceptfor sugar loss %, sugar loss yield (ton fed.-1), α-amino-N and Na concentration ofroot in both seasons.It could be concluded that the highest sugar yield and the best technologicalquality of sugar beet were obtaining by using 100 ppm boron concentration andspraying after 70 days after planting under newly reclaimed soil conditions

Effect of Spondias mombin on Intake and Digestibility in West African Dwarf Sheep Fed Graded Level of Whole Cassava Root Meal Based Diet
Effect of Spondias mombin on Intake and Digestibility in West African Dwarf Sheep Fed Graded Level of Whole Cassava Root Meal Based Diet
The supplementing of Spondias mombin instead of concentrate mixture dietsand its effect on feed intake body weight change and digestibility was investigatedusing sixteen West African Dwarf Sheep in a completely randomized designexperiment. The diets used were 100% concentrate (Diet 1; control), 75%concentrate plus 25% Spondias mombin (Diet 2), 50% concentrate plus 50%Spondias mombin (Diet 3) and 25% concentrate plus 75% Spondias mombin(Diet 4). Dry matter intake was significantly (P < 0.05) higher in sheep fed concentratediet plus Spondias mombin (Diets 2, 3 and 4) than those fed concentratealone (Diet 1, control). The highest dry matter intake was exhibited by sheep fed50% concentrate plus 50% Spondias mombin. Sheep fed concentrates plusSpondias mombin exhibited a superior daily weight gain to those fed concentratesonly. Live weight gain was not significantly (P > 0.05) different between diets 3and 4. However, a significant (P < 0.05) difference existed among diets 3 and 4,and the other two dietary treatments. Feed conversion (feed/gain ratio) was significantlyhigher (P > 0.05) in animals fed diets 3 and 4 than those diets 1 and 2.Nutrient digestibility was not significantly (P > 0.05) influenced by dietarytreatments. In conclusion, the intake and digestibility of nutrients by West AfricanDwarf were best when up to 50% and above of Spondias mombin was includedin the diet. Therefore an indication that Spondias mombin could providethe needed nutrients for sheep especially during the dry season when feed resourcesare scarce

Chemical Composition and Variation in Mean Values of Selected Crop Residues Fermented with Local Alkali Sources and Rumen Filtrate
Chemical Composition and Variation in Mean Values of Selected Crop
Residues Fermented with Local Alkali Sources and Rumen Filtrate
A twenty-one (21) day fermentation trial was conducted to determine thechemical composition of four crop residues separately fermented with each oflocal alkali agents (cocoa pod ash, palm bunch ash lye solution and rumen filtrate).Results showed that Dry Matter DM contents of cocoa pod husk ash, fermentedcom cob and corn husk decreased significantly (P<0.05) while those ofrice bran, rice husk were either similar (P>0.05) to or significantly lower(P<0.05) when compared with the control. Meanwhile fermentation with cocoapod ash and palm bunch ash decreased (P<0.05) both the CP and fibre contentsof all crop residues listed. Fermentation with rumen filtrate increased the CP contentsby more than two (2) folds but decreased the fibre, contents compared to thecontrol by 19.31 and 13.57; 11.28 and 820; 29.58 and 12.52; 1533 and 16.99 forcorn cob, corn husk, rice bran and rice husk respectively. Also Fermentation withcocoa pod ash, palm bunch ash and rumen filtrate increased (P<0.05) the ashcontents substantially in all crop residues. In conclusion, fermentation has beenconfirmed to enhance nutritional value of feedstuffs. However, due to microbialdigestion effects, fermentation with rumen filtrate seemed to be superior overthese of cocoa pod husk ash and palm bunch ash.

Phosphorus applications (0.6, 1.2 and 1.8 gm/kg soil) were applied to sixleguminous tree species; Acacia laeta, Acacia abida, Acacia nilotica, Acacia farnesiana,Tamarindus indica and Haematoxylum campechianum to define thesuitable P rate for favorable growth. The heaviest roots in average of bothseasons; fresh and dry were obtained from T. indica. The thickest and heaviestshoot were resulted from A. laeta. The longest roots recorded by A. nilotica andA. farnesiana. The maximum N and P contents were obtained by T. indica. Theother species achieved intermediate levels of N and P. In relation to P application,a rate of 1.2 gm/kg of phosphorus was the best for shoot diameter and rootlength, meanwhile, 1.8 gm/kg increased fresh and dry weight of both shoots androots. Leaf content of N was increased with increasing P from 0.6 to 1.8 gm/kg.Phosphorus addition at 1.2 gm/kg was more effective in accumulation of P concentration

The present study carried out during 2011 and 2012 seasons on “Zaghloul”and “Samany” date palm cultivars grown on new reclaimed sandy soil, at NewAsuit City. Egypt, to investigate the effect of spraying with two sources of micronutrientSilicon (KSi 10 % (A1) and K2O 10%+ SiO2 25 % (A2) on fruit retention,bunch weight , total yield as well as some physical and chemical fruitproperties. The two Silicon materials sprayed once, twice and thrice one weekafter pollination and 60 and 120 days later, respectively.In general, inflorescences spraying with A1 and A2 sources at 0.8% onetime (one week after pollination) caused a significant increase in fruit retentionpercentages as compared with control treatment in the two studied cultivars duringboth seasons. Also, extending and repeating spraying times after pollinationcaused a significant increase in fruit retention, bunch weight, total yield, fruitweight, fruit dimensions and fruit content of TSS, total and reducing sugars inboth studied cultivars.Palms that have been sprayed three times with K2O 10%+ SiO2 25 % (A2)produced the highest yield components (fruit retention, bunch weight and totalyield), fruit weight and dimensions as compared with other treatments on bothcultivars during both seasons. The chemical fruit properties (TSS % as well astotal and reducing sugars %) under such treatments were higher than those underKSi 10 % (A1) treatments in “Zaghgloul” fruits while the opposite trend observedin “Samany” fruits treated with KSi 10 % (A1) where it was more effectiveon improving chemical fruit properties than K2O 10%+ SiO2 25 % treatments.No significant differences were found between all silicon treatments andcontrol on seed weight and fruit content of tannins.Generally, the obtained results concluded that spraying “Zaghloul” and“Samany” inflorescences three times with K2O 10%+ SiO2 25 % (A2) as asource of potassium silicate was useful to gave a high yield /palm with high fruitquality and could be consider as a recommended treatment under conditions ofthis experiment.

Effect of Silver Nanoparticles on Salt Tolerancy of Tomato Trans-plants (Solanum lycopersicom, Mill.)
تأثیر جزیئات الفضة النانومتریة على تحمل الملحیة فى شتلات الطماطم
A pot experiment was conducted at the Experimental Farm, Faculty of Agriculture, Assiut University, Assiut, during the summer seasons of 2014 and 2015 to study the effect of Silver Nanoparticles (SNP) on salt tolerance in tomato. The experimental soil type was clay. Split plot arrangement in Randomized Complete Blocks Design (RCBD) with four replicates was used. The salt solution (sodium chloride) concentrations [(0 %( control plots were irrigated with deionized water), 30, 60, 90, 120 mM/L)] were distributed in main plots, while the Silver Nanoparticles concentrations [(0 %( control plots were soaked in distilled water), 10, 20, 40 ppm)] were arranged in sub plots. The obtained results indicated that soaking tomato transplants in Silver nanoparticles for 24 hours had no significant effect on increasing tomato tolerance to sodium chloride salt within the used levels. This was reflected in negative effects on fruit number per plant, fruit diameter, average fruit weight, number of branches per plant and plant height. The control treatment (soaked in distilled water) of SNP was consistently superior for all studied traits. SNP treatments reduced the fruit number per plant, fruit diameter, average fruit weight, number of branches per plant and plant height

An Economic Study of the Determinants for the Supply Response of the Cotton Crop in Egypt
دراسة اقتصادیة لمحددات استجابة العرض لمحصول القطن فى مصر
Farm prices are one of the key economic variables affecting the productiondecisions of farmers through their response to cotton prices or to competitivecrops price in the same season, as well as some other economic variables thatspecify the cultivated areas and quantities produced from cotton. So that thestudy aims to assess the Egyptian cotton crop supply response functions in orderto identify the degree of response of farmers to price and some importanteconomic variables affecting the area under cotton In addition to estimatingelasticity respond to these variables during (1997-2013).According to the results of instability coefficient estimated in the study,there is a lack of stability in all the years of study in the area under cultivation,production and farm price for cotton crop , where it came from all of them isequal to zero during the study period.There was a statistically significant response in the current area of cotton tochanges in the feddan productive variables, farm price and net income ,and thetotal cost of feddan with a delay of one year, the longest response was for netreturn, followed by both productivity, farm price and production costs perFeddan. The results of estimating supply response functions to cotton crop byusing multiple regression nerlov model with explanatory variables of thecompeting crops for the cotton such as net income for maize and rice to give atotal elasticity response about -3.17.The current cotton area response to change in both the farm price for cotton,corn and rice in the previous year, with total elasticity of respond about-0.23.alsothere is a Response in the current cotton area to the change in all of theproduction costs of cotton and corn and rice production costs in the previous yearwith elasticity of response about -0.57.Some recommendations can be drawn from the study: Need to find somesort of price stability for the cotton crop, which leads to the stability of cultivatedareas and production of cotton, as well as the need to provide control over theprices of inputs to ensure that the high production costs of cotton crop and thereluctance of farmers growing the crop. You must provide information to farmersabout the competing crops for cotton

Animal tissue is the only source of animal protein, a vital food necessaryfor a person, so it is not seen to livestock production as a kind of productive activityis a character Da'amy in the national economy in various image, but alsoconsidered products of the important nutrients and the necessary equipment forbody composition configuration sound natural For the production of animal itdoes not obtain sufficient attention within the province where noted that the ratioof the number of animals is very little to maintain the number of animals for theRepublic, where the figure is estimated at 6.65% in 2014.Where the number ofanimals and the province and the republic was estimated at 1325,19937thousandheads respectively.The problem of the study: Red meat production inability to maintain tomeet the growing needs of red meat as a result of the continuing increase in thenumber of population. Alternative products high red meat prices. Which leads toresort to import from foreign markets. In the form of meat and live animals tocover the deficit between production and consumption.The study aims: Analysis of the productive efficiency of cattle bred traditionalsystem of education through the various stages of the farms sample differentstrains. Evolution of the number of animals produced for meat and red meatquantities produced from them.The development of green fodder quantities producedand manufactured in the governorate.The study found the following results:1- Proved a significant change in the number of live animals from cattle,sheep and goats.It did not prove a significant change in the number of buffaloand BeautyDuring the period (2000-2014).2- A surplus in the amount of green fodder producing estimated at 511 tons,While there is a deficit in the amount of feed manufacturers and feed coarse estimatedat 2006 tons, 1449.317 tons.3- When estimating the consumption function; When increasing the price ofred meat and fish prices rose 10% resulted in an increase in the amount of consumptionof red meat by 2.6%, 2.7%, respectively. increase the population by10% resulting in a lack of quantities consumed by 15.7%.Moral effect of thechange has not been proven in the prices of poultry. Combination of factors isresponsible for the change in the quantities consumed by 87%.4- In estimating production functions for different strains in different fatteningstage:Proven efficiency fattening process and the mixture of buffalo in variousstages of production (three).While proved the efficiency of the process of fatteningcattle farmyard in the first and second phases., While foreign efficiencyfattening process proved to strain during the first and third phases.5-There were many problems facing educators which was the most prominent:The spread of foot and mouth disease, The increase of prices of veterinarymedicines, Higher interest on loans for educators prices, Not to feed on the marketsupport, Higher feed prices.The most important proposals submitted by educators were are: Establishmentof a special hand to support educators, Improving veterinary service,Adjust feed Exchange, The establishment of private livestock insurance points.

She is responsible for raising responsible future generations. She is the wife who manages home. She is the mother, sister, daughter and wife. in spite of that woman is exposed to all kinds of violence from man (husband, father, brother, etc.). This violence takes various forms, including physical, psychological, sexual, economic. circumcision. early marriage. denial of education, denial of inheritance and inequality between the boy and the girl in Education.
Violence against woman, in almost all societies, is a very complicated issue. It is a worldly problem that exceeds cultural and geographical boundaries. The rural society is greatly influenced by this problem. The woman in Assiut governorate (place of study), like woman allover Egypt, is expised to all forms of violence. Through real statistics taken from family court in Assiut governorate it is clear that the problem of violence is in continuous growth. As a result it was important to have a study about all forms of violence against rural woman in the governorate, know the reasons and the circumstances of this violence, woman`s reaction, what the results of this on her and her children, and try to find solutions to limit violence against her.
Data have been collected from rural ladies who have problems in the family court. The result shows us a relevant physical, psychological, sexual, economic violence.
Results showed a variety of reasons pushing man to treat her violently like : customs and traditions, religious conceptions misunderstanding, bad behaviors, nervous, avarice, Parental involvement, husband character weakness, work stress, Lack of employment opportunities, poverty, and illiteracy.
Woman's known reactions are crying, and leaving husband's home and going to her familiy's home and as a result she becomes sad, lack of self confidence and hatred to all men.
Women saied that children is the victim of this violence whether the couple divorced or not. The children become in a ver bad mode, lack of self confidence , always Vulnerable to disease, failure in school and fear from others.
As the results show, Woman is exposed to violence from her own family members; from her father, brother, and mother like: discrimination between boy and girl in treatment, early marriage, obligatory marriage, and circumcision.
Results also showed that Women are harassed in the streets, transportation, hospitals, and governmental offices in Assiut governorate.
Of the most important solutions to address violence against women are good education, the right religious education for children, men in the family have to know their role, the existence of strict laws to punish the husband or the harasser and the female literacy.
