Interaction Effect of Biological and Organic Fertilizers on Yield and Yield Components of Two Wheat Cultivars

TWO FIELD experiments were carried out during winter seasons 2006/2007 and 2007/2008 in the farm at Faculty of Agriculture (Saba Basha). Alexandria University, Egypt. The local unit area was utilized feddan (fed ) 4200 m2 . The aim of the study was to examine the effect of 3 bio-fertilizers (Cerealine- commercial product contain Azospirillum spp.. yeast, control) and 4 rates (zero. 10. 20. 30 m3/fed) of sheep manure on yield and its components of 2 wheat cultivars (Gemiza-7 and Sakha- 93). The experiment consisted of 24 treatments which were the combinations between three factors : two cultivars. three bio-fertilizers and four organic fertilizer rates in four replicates. Data indicated that Gciniza-7 surpassed Sakha-93 in spike length, number of grains/spike, grain, straw, biological yields/fed and harvest index %. while Sakha-93 surpassed Gemiza-7 in number of spikes /m2 , spike weight and weight of 1000-grains. The bio-lertilizer (yeast) hpd the superiority in number of spikes /m2 . The organic fertilizer (30 m2/fed) in the form of sheep manure gave the best results for all studied characters. The interaction between Sakha-93 and yeast gave the best results for all other studied characters. The interaction between Sakha-93 and 30 m3 / fed sheep manure gave the best yield and yield attributes. The interaction between yeast and 30 m /fed sheep manure surpassed the other interactions for all studied characters. The interactions of the three factors indicated that interaction of Sakha-93 x yeast x 30 m3 / fed sheep manure gave the best results for all studied characters
