The aim of the study was to examine the response of wheat cultivar Sakha-93 to 3 weed control treatments and two sowing methods.The experiment included 6 treatments which were the combinations of two sowing methods 1-in ridges 2-rows and response of wheat cultivar Sakha-93 to 3 weed control treatments 1-Unweeded (control) ; 2-Hand weeding twice at 30 and 60 DAS 3-Chemical weed control by Panther 55% Sc at post emergence. The treatments were arranged in split plot design in four replicates, sowing methods in main plots and weed control treatments in subplots. Combined analysis used for the two seasons. Data indicated that sowing wheat c.v Sakha-93 in ridges surpassed in rows for no. of tillers ; spikes/m 2 ; spike length ; spike weight ; grains weight/spike ; grain; straw; biological yields as kg/fed.; harvest index % ; protein ; phosphorus and K yields as kg/fed. On the other hand, sowing in rows produced taller plants, heavier 1000 grains weight. . Results showed that chemical weeded had superiority in total, broad leaved ,grassy weeds either fresh or dry/m 2 at both samples 75 and 105 DAS ,also, in no. of tillers/m 2 ; no. of spikes/m 2 ; spike length ; spike weight ; grains weight/spike ; 1000-grains weight ; grain yield/fed. ; harvest index% ; protein ,P,K yields (kg/fed.) whereas hand weeding produced tallest plants , highest protein ,P,K% in grains. Interaction of sowing method in ridges and chemical weeded significantly surpassed other treatments in no. of tillers/m 2 ; no. of spikes/m 2 ; spike weight ; straw and biological yield as kg/fed. Interaction of sowing method in ridges and hand weeding gave the highest content of protein ; phosphorus and potassium in wheat grains as kg/fed.

Two field experiments were conducted during two successive winter seasons of 2008/2009 and 2009/2010 to investigate the potentialities of mixing Egyptian clover with ryegrass under bio, organic and mineral fertilization treatments and their combination to increase forage yield and quality grown under sandy soil conditions. The experiment included the combination of five mixing ratios (Egyptian clover alone, ryegrass alone, 75% Egyptian clover: 25% ryegrass, 50% Egyptian clover: 50% ryegrass and 25% Egyptian clover: 75% ryegrass) and eight fertilizer sources, which include control, organic fertilization, bio fertilization, chemical fertilizer, organic + bio fertilizer, organic + chemical fertilizer, bio + chemical fertilizer and combination of organic and chemical and bio fertilizers. The obtained results indicate the superiority of 75% E. clover: 25% ryegrass mixture fertilized by Bio + O + N in fresh and dry forage production. On the other hand, it reported the lowest dry weight of weeds g/m 2. Chemical analysis of forage plants showed that the mixture of 75% E. clover: 25% ryegrass surpassed that of other treatments yield for crude protein, ether extract and ash. The results also revealed that the highest record of DCP, crude fiber and TDNY was obtained by forage mixture of 75% E. clover: 25% ryegrass fertilized with Bio + O + N. Such higher yield of these characters has secured a balanced ratio which is really needed for ruminants ration.

A pot trial was carried out in the greenhouse of the National Research Centre during the summer season of 1999 to investigate the combined impact of Bradyrhizobium sp. (vigna) and Azotobacter vinelandii in the presence of various doses of chemical fertilizers, i.e. 25%, 50% and 100% of the recommended dose of NPK, on nodulation, growth parameters, seed yield and its components, and seed contents of protein, phosphorus and potassium of a local (Kawmy-1) and three exotic (VC-4, VC-9 and King) varieties of mungbean. The results indicated that there were no significant differences between the different varieties for nodule number per plant, while significant variations were obtained between both varieties and biofertilization treatments.The plants of the Kawmy-1 variety gave the shortest period of growth, the highest number of pods per plant and the highest values of harvest index and seed protein content. The King variety had the longest period of growth and the highest values for number of branches, seed yield, biological yield, seed index and seed phosphorus content. The inclusion of Azotobacter vinelandii significantly augmented various tested parameters, with the exception of seed yield, biological yield and potassium content, in comparison with Bradyrhizobium. Insignificant differences were found owing to the interaction between varieties, various levels of mineral fertilizers and types of biofertilizers with the exception of harvest index and seed phosphorus content.
