| Abstract | ||||
| Two field experiments were carried out in the Experimental Farm , of the Faculty of Agriculture , Fayoum University on Sandy Loam soil during 2011 / 2012 and 2012 / 2013 seasons to study the effects of two organic manure levels i.e. (15 and 30 m3 / fed.), biofertilizer (Azotobacter who was inoculation the seeds) and three levels of nitrogen fertilizer .[100% (75 kg N / fed. ) & 50 % (37.5 kg N / fed.) and 25 % (18.75 kg N / fed.) ] of Urea ( 46 % N) and their combinations on productivity of two wheat cultivars i.e. (Sakha 93 (V1) &Sakha 94 (v2)).The treatments were set in Randomized Complete Block Design (RCBD) in factorial arrangement with three replications . Significant effect for wheat varieties were obtained on plant height (cm) , in the 1st season and on total protein percentage in both seasons but was insignificantly on other traits .The superiority was for Sakha 94 in most characters . Fertilizer treatments was significantly effect on all traits in both season except plant height , number of spike / plant ,1000-grain weight in second season and harvest index% in first season .F3 ( 30 m 3 / fed. organic manure + bio – fertilizer + 50 % ( 37.5 kg N / fed.) treatment gave the highest values followed by F4 (30 m 3 / fed. organic manure + bio – fertilizer + 25 % (18.75 kg N / fed.)) or F5 (30 m3 / fed. organic manure + 50 % (37.5 kg N / fed.)) treatments . Interaction between varieties and fertilizer treatments was significantly effect on number of spike / plant and weight of grains / spike in both seasons and on grain yield (ton / fed.) and total protein (%) in 1st and number of grains / spike in second season only but was insignificantly on plant height (cm) , 1000-grain weight, and harvest index (%) in both seasons . Results of stepwise regression revealed that both the harvest index, 1000 grains weight, number of grains/ spike and plant height were causes high grains yield genotypes in wheat programs. By using organic fertilizer and / or bio-fertilizer with half dose of mineral fertilizer it could be increased in plant growth and yield . Besides, using bio-fertilizers that contain different microbial strains had led to decrease in the use of chemical fertilizers and had provided height products free of harmful agrochemicals for human safety. | ||||
