To study the effects of foliar application with micronutrients on yield and yield components of faba bean (c.v. Misr 1), an experimental research was conducted in complete randomized block design by three replications during the two growing seasons of 2009/2010 and 2010/2011 in Etay El-Baroud Agricultural Research Station, El-Behera Governorate. Results shwoed that, spraying with Fe+Zn+Mn increased plant height, number of pods/plant, number of seeds/pod, number of seeds/plant, 100 seed weight and seed yield /faddan in the combined data. Also, chemical constituent, chlorophyll A, chlorophyll B, reducing sugars and the non reducing sugars significantly increased in all treatments spray with micronutrients compared with non-treated (control). Meanwhile, Altermaria leaf spot incidence on treated plants significantly decreased 18.2%-60.5% compared with non-treated control plants.

Two field experiments were conducted at Gemmeiza Agric. Res. Stat. during 2011/12 and 2012/13 growing seasons, to study the influence of different irrigation regimes i.e. irrigation at tillering stage (I1), at tillering and heading stage (I2) and at tillering , heading and grain filling stage (I3) with three methods of sowing i.e. broadcasting, drilling and beds sowing on yield and its components of four wheat cultivars namely Gemmeiza-11, Misr-1, Shandaweel-1 and Sids-12.A significant reductions in grain and straw yields in both seasons was obtained as a result to subjecting wheat plants to drought-stress. Results showed that three irrigations increased significantly number of spikes/m 2 , number of grains/spike, 1000-grain weight, grain weight/spike, biological yield and harvest index except protein content. It could be noticed beds sowing method gave highest yield components. Gemmeiza-11 wheat cultivar surpassed the other tested cultivars concerning with the above mentioned traits, except number of spikes/m 2 and straw yield. While, Misr-1 surpassed in no. of spikes in both seasons and harvest index in the second season, however, Shandaweel-1 produced the highest protein content. A significant interactions between the effect of irrigation (I), sowing methods (M) and wheat cultivars (V) were found in increasing the yield and its components, except between irrigation and sowing methods (I x M) concerning with grain weight/spike (g), grain yield (ardab/fad), straw yield (ton/fad) and biological yield (ton/ fad) in the second season only. Correlation positive and significant relationships between grain yield/fad and all yield components. It could be concluded that to get highest productivity of wheat under middle delta region conditions it must cultivate Gemmeiza-11 cultivar with addition of three irrigations with using the beds sowing method.

In order to investigate the influence of different irrigation regimes i.e. irrigation at tillering stage (I1), at tillering and heading stage (I2) at tillering , heading and grain filling stage (I3) of the available soil moisture depletion with three methods of sowing i.e. broadcasting, drilling and beds sowing on some and characters of growth attributes, relative water content, water use efficiency and drought susceptibility index for four wheat cultivars namely; Gemmeiza-11,Misr-1, Shandaweel-1 and Sids-12. So, two field trials was carried out during 2011/12 and 2012/13 seasons, at El-Gemmeiza Agric. Res. Stat. The results can be summarized as follows: Subjecting wheat plants to drought-stress resulted in a significant reduction in plant height, number of days to heading, number of days to maturity, grain filling period, flag leaf area and relative water content. Water use efficiency and total chlorophyll content tends significantly increased as irrigation regime decreased. Moreover, number of days to heading, number of days to maturity, grain filling period and flag leaf area were insignificant differed due to the tested sowing methods. However, beds sowing method was significantly differed total chlorophyll content, relative water content and water use efficiency. Gemmeiza-11 cultivar surpassed others tested cultivars with respect the abovementioned traits, except number of days to maturity since Shandaweel-1 cultivar was the earliest. Wheat plants grown under severe water deficit were more sensitive to drought. This was clear from drought sensitivity based on drought susceptibility index. Sids-12 and Misr-1 cultivars was proved to be the most drought-tolerant cultivar compared to the other tested ones.

Two field experiments were carried out at El-Gemmeiza Agricultural Research Station, El-Gharbia Governorate during two successive seasons of 2012 and 2013. These experiments were conducted to study the probability of using clean agriculture to produce organic cotton and reduce environmental pollution. A randomized complete block design with 4 replicates was used in both seasons, where the following twelve patterns were evaluated with regard to growth and its attributes of the Egyptian cotton (Gossypium barbadense, L.), cultivar Giza 86:-Patterns 1, 2, 3 and 4 included two rates of mineral NPK fertilizers (45 kg N: 22.5kg P2O5 :24 kg K2O /fed (the recommended rate) and 60 kg N :30 kg P2O5 : 36 kg K2O /fed) in combination with chemical or bio-control, respectively.
