The objective of the present study was evaluation for the effects of maize hybrids (SC 166, SC 176 and TWC 352) all of them are yellow grains, different nitrogen fertilizer sources (ammonium sulphate, ammonium nitrate and urea) and bio-fertilizer levels (0, 250 and 500 gm. Cerealin/ fad.) on growth, yield and its components and yield analysis. To assess the various treatment effects on grain yield and other morphologic traits, two field experiments were conducted in a private farm at one of the villages of Zefta District, Gharbiya Governorate, Egypt during 2014 and 2015 summer seasons.
The experimental design was set up as split-split plot in a randomized complete block with three replications. Maize hybrids and nitrogen sources consider as main and sub plots respectively, under three bio-fertilizer levels as sub sub plots. Maize hybrids had a significant effects (P< 0.01) on the grain yield in both seasons, but not on the number of rows/ear.
While the highest grain yield was obtained from planting SC166, planting SC176 gave the highest ear length, number of grains/row, number of grains/ear , shelling percentage, grain weight/ear and Oil percentage. Nitrogen sources affected significantly (p< 0.01) almost of grain yield and except shelling % its components in both seasons, were ammonium sulphate gave the highest grain yield/fad. compared to the other two forms of nitrogen. Increasing bio-fertilizer levels up to maximum level increased significantly grain yield and all of the yield components, except both shelling percentage and oil percentage, where the differences among bio-fertilizer levels in these traits were not significant.
The combined data across the two growing seasons showed that the ear length, number 0f grains/row, number of grains/ear, shelling percentage, grain weight/ear, 100-grain weight and straw and biological yield/fad. had positive and significant relationships with grain yield/fad. These results imply that most of these traits contribute to increase in grain yield.
Thus, they also form critical traits for maize improvement. Further, oil percentage showed a negative relation with grain yield/fad. path analysis study showed that the direct effect of number of row/ear was 69.11% of maize grain yield variation, while the direct effects of number of grains/row and 100-grain weight were 3.44 and 3.85% of grain yield variation, respectively.
Conclusively, from these results it could be concluded that the maize hybrid S.C.166with the use of nitrogen fertilization ammonium sulphate 20.6%with bio – fertilization500gm/fad in the area of the Nile Delta.

A field experiment was carried out at Sides Agricultural Research Station in Beni-Suif Governorate during 2015 and 2016 seasons to study the effect of some intercropping patterns for basil by100% + maize (25%, 33% or 50%) and three maize cultivars (S.C. 167, T.W.C. 314 and Giza 2) on growth, yield and yield components of basil and maize. A split-plots design with three replications was used. The main plots were devoted to the previous three maize cultivars, whereas, the sub-plots were allocated to the intercropping patterns of maize cultivars with basil. The main obvious results of this study can be summarized as follows. The results revealed that S.C. 167 maize hybrid gave the highest values for yield and yield components characters, while Giza 2 cultivar gave the lowest values in both season. Under interaction, when maize plant density with basil was increased from 25, 33 up to 50 %, grain yield and components of maize recorded gradually increase, as well as maize grain yield had the same trend. The yield of basil and its components as well as essential oil percentage were significantly affected by the intercropping of maize with it, whereas the decrease was evident when intercropped the S.C. 167 followed by T.W.C. 314 and Giza 2. Maximum values of land equivalent ratio (LER) (1.31) when intercropped G. 2 with basil by 100% basil + 50% maize and relative crowding coefficients (10.83 and 15.66) were observed with G. 2 when intercropped by 25% with 100% basil in both seasons, respectively. The data indicated that maize was the dominate and basil was the dominated in all patterns. The return showed that intercropping maize with basil in most treatments was lower compared to solid maize or solid basil planting. The highest net return were LE 14644 when intercropped G. 2 with basil by 100% basil + 25% maize whereas the different between the highest and lower value was LE 6110 in combined data across two seasons.

This work was carried out duringthe two successive seasons of 2015/16 and 2016/17 at the Expt. Farm of South Tahrir, Hort. Res. Station. The experiment aimed to evaluate the effect of three irrigation rates (1200, 1500 and 1800 m3 water/ fadand four potassium fertilization levels (0, 50, 100 and 150 kg K2SO4/ fad) and their interactions on moghat growth and productivity as well as evaluate to what extent these treatments affect soil properties.
Gradual increases in plant height, root length, root diameter, as well as, roots fresh and dry weights/ plant were noticed with increasing irrigation rate from 1200 m3/ fad up to 1800 m3/ fad. This was associated with an improvement in roots quality. Increasing irrigation rate significantly increased percentages of total protein and potassium in moghat root tissues, but decreased mucilage percentage. The highest mucilage percentages in roots were found in plants irrigated with the lowest irrigation rate (1200 m3/fad).
Potassium fertilization enhanced plant growth as plant height, root length and root diameter. This was reflected as increases in root fresh and dry weights/ plant. The highest values represented the abovementioned measurements were found in plants received the highest potassium fertilization level (150 kg K2SO4/ fad). Moghat plants received 150 kg K2SO4/ fad resulted roots contained high percentages of mucilage, protein, potassium and total amino acids.
When, irrigation rates interacted with K fertilization levels, more increases in plant height, root length, root diameter, roots fresh and dry weights/ plant and K percentage in root tissues were found. The highest values of the abovementioned measurements were recorded in plants irrigated with 1800 m3/ fad and fertilized with 150 kg K2SO4/ fad. The same treatment resulted in increases in number of capsule/ plant, number of seeds/ capsule and seed weight/plant. Interaction treatment of 1200 m3 irrigation water/ fad combined with 100 Kg K2SO4/fad resulted in the highest mucilage % in roots comparing to the all other interaction treatments.
Conclusively, the obtained data showed that addition any of the previous treatments led to an improvement in some of the physical and chemical properties of soil, due to increasing organic content. While, bulk density, hydraulic conductivity, EC and pH values were decreased

The effect of using Oat flour to improve the functional properties of cake and biscuit was explored. Oat flour in the cake and biscuit formulation was replaced at four levels, 25, 50, 75 and 100% with whole meal wheat flour(wmwf). Biscuit and cake containing only whole meal wheat flour was used as control. Raw materials, prepared cake and biscuits were analyzed for their proximate composition, baking quality of cake (weight, volume, specific volume) and biscuit(diameter, thickness, spread ratio, weight, volume, specific volume), color, texture, stalling and sensory evaluation. Rheological properties of mixed oat flour with whole meal wheat flour were studied.
Results revealed that, the chemical composition of oat flour and whole meal wheat flour resulted in a significant increase in fibre and ash contents and a decrease in protein and carbohydrate content compared to whole meal wheat flour. Farino graph parameters showed that water absorption, dough weakening and arrival time increased as Oat Flour level increased in the blends. While dough stability and mixing tolerance index were decreased by adding Oat flour to whole meal wheat flour at all levels replacement. The adding of Oat flour to Whole meal wheat flour led to increased of transmission temperature, temperature of peak viscosity and peak viscosity.
Cake weight produced from Whole meal wheat flour with oat flour were lower than compared to control, while, its volume and specific volume of cake produced from Whole meal wheat flour with oat flour was increased as the level of oat flour increased in cake. Cake produced from Whole meal wheat flour withoat flour at different levels (25, 50, 75 and 100%) caused a noticeable decrease in alkaline water retention capacity values compared with control at the same storage period. Results also showed that Hunter color parameters (L*, a*andb*) of biscuits and cakes were lightness were increased as mixing level of oat flour increased. This result was confirmed with the obtained sensorial results. Moreover, sensory evaluation of biscuits and showed that all samples were acceptable, but sample which contained oat flour had superior sensory characteristics, nutritional value and was suitable for Diabetic and Obesity.

ABSTRACT
Studies were carried out at El-Khattara district, Sharkia Governorate during two successive years 2016 and 2017 to study susceptibility of three potato cultivars (Spunta, Cara and Galactica) to infestation with aphids and whitefly.
The results showed that the infestation differs from variety to another, whereas Galactica cultivar was less susceptible followed by Cara cultivar, while Spunta cultivar showed the most susceptibility to infestation by aphids and Bemisia tabaciand associated with the greatest number of insect predators (Coccinella septempunctata L., C. undecimpunctata L, C. 9 puncata , Chrysoperla carnea Steph. and Metasyrphus corollae F.) followed by Cara and Galactica cultivars. The statistical analysis showed that this difference was highly significant among the different cultivars by aphids and whitefly infestation. As regards the effect of mean temperature and atmospheric relative humidity as well as their total combined effect on the numbers of certain investigated insect species and their predators, it is obvious that the effect was clear. The effect of the chemical contents of potato plants on the population density of aphids and whitefly that infest certain potato cultivars, indicated that a negative correlation appeared between population density of (aphids and whitefly), and protein, carbohydrate, phenols, pH, Nitrogen (N) %, Phosphorus (P)% and potassium (K) % percentage in the three potato cultivars.
Conclusively, the obtained results in developing the IPM programs against these pests on potato plants through activation the effect of both temperature and relative humidity on insect numbers and the need to conduct more of these studies.

Two Factorial field experiments on wheat (Var. Msr2) wereconducted during two successive seasons (2015/2016 and2016/2017).The factors involved gypsum application (none, 100%gypsum requirements) × organic fertilizer rate (none, 20 m3 fed-1) ×nitrogen fertilizer rates (none, 100 kg N fed-1) × zinc fertilizer rates(none, 5 kg Zn fed-1) × 4 replicates. The soils of the experimentallocations have been clay loam in texture and the mean values of someproperties were ECe = 6.40 dS.m-1, ESP = 18.11 % , pH = 8.30 whichreveals higher effects with salinity and sodicity.The important results could be summarized as follows:1- The addition of gypsum according to soil gypsum requirements (GR)prior wheat cultivation resulted in higher wheat yields as a result ofits ameliorative role in soil-pH; soil-EC; soil-ESP and subsequentlyincreasing the availability of some nutrients.2- Better wheat yields have been obtained by adding organic manure of20 m3 fed-1 compost, as a result of modifying various soil physicochemicalscharacteristics and subsequently increasing most nutrientsavailability.3- Nitrogen fertilization with the recommended rate of 100 kg N fed-1 (asAmmonium sulfate) led to higher wheat yields as compared to nonefertilizedtreatment.4- Zinc sulfate fertilization at rate of 5 kg Zn fed-1 for wheat led to betteryields; where that response is related to native Zn- unavailability dueto higher values of soil-pH and soil- ESP.5- The significant interaction of those variables on wheat yield and wheatgrains-N and Zn concentrations as well as protein content revealed thattheir use efficiencies have been affected with each other. The coadditionsof (GR)×organic manure × N-fertilizer ×Zn fertilizer were344 GENEDY et al.highly beneficial in improving N and Zn nutrition for wheat yield insuch soils.

The present study were conducted at Privet Farm in Al-Rahmania Island, Behaira Governorate, Egypt, during two successive summer seasons of 2016 and 2017, to identify the interrelationships among fruit yield and its related characters using correlation and improved model of path analysis at both genotypic and phenotypic levels on chilli pepper (Capsicum annuum L.).
The experimental genotypes were grown in randomized complete blocks design (RCBD), with three replicates on open field. Eight tested genotypes namely, i. e. Shata Balady Hot cv, Shata Balady Hot line-1, Shata Balady Sweet cv, Serrano cv, Shata Balady Sweet line-3, Shata Balady Sweet line-4, Anheium cv, and Cayenne Large cv were used in this study. The characteristics were studied i.e., plant height (PH); branches number plant-1 (BN); fruit length (FL); fruit diameter (FD); locales number fruit-1 (LN); average fruit weight fruit-1 (AFW); fruits number plant-1 (FN) and yield plant-1 (Y).
The results revealed that, there are a significant differences among genotypes for all studied characters. Also, significant and positive correlation coefficients were obtained between fruit yield plant-1 and number of fruits plant-1, at the genotypic and phenotypic levels (0.743* and 0.742*), respectively. Moreover, significant and negative correlation coefficients were obtained between yield plant-1 and fruit diameter (- 0.889** and - 0.882**) at the genotypic and phenotypic levels, respectively.
Path analysis (genotypic and phenotypic) coefficient showed that the traits, i.e. branches number plant-1 and fruits number plant-1 and the average of fruit weight gave the maximum influence directly and indirectly upon yield plant-1 in chilli pepper indicating their magnitude as selection criteria to obtain a valuable gain of selection for yield in chilli pepper.
Conclusively, these results may be helpful to plan appropriate selection strategies for improving fruit yield in hot pepper.
