Effect of bio-organic fertilization and some weed control treatments on yield and yield components of wheat.

摘要: Two field experiments were carried out during winter seasons 2004/2005 and 2005/2006 in the Experimental Station of National Research Centre, Shalakan District, Kalubia Governorate, Egypt. The investigation aimed to study response wheat cultivar Sakha-93 three weed control treatments 1-Unweeded (control),2-Hand weeding twice at 30 60 DAS 3-Chemical by Panther 55% Sc post emergence five bio-organic fertilization which 1-Recommended dose fertilizer 10m /fed. chicken manure + cerealine (bio-fert.) commercial product contain Azospirillum sp. 2-75% 3 rec. organic fert.+cerealine +25% NPK 3-50% fert.+cerealine+50% 4-25% fert.+cerealine+75% 5-100% recommended (NPK 75:31:48 kg/fed.). Results showed that chemical weeded had superiority total, broad leaved,grassy weeds,also, no. tillers/m , spikes/m spike 2 length, weight, grains weight/spike, 1000-grains grain yield/fed., harvest index %, protein,P,K yields (kg/fed.).Hand produced tallest plants, highest % grains. Treatment 25% bioorganic+75% gave best reduce fresh dry leaved, grassy total weeds 75 105 DAS,also, yield components, (kg/fed.) except for plant height straw yield. On other hand, 100% %.
