Effect of Scheduling Irrigation Water and Adding Organic Matter and Bio-Fertilizer on the Concentration of some Nutrients in Wheat Plant (Triticum aestivum L.)

Abstract A field experiment was applied during the agricultural season 2021-2022 in one of farms located Al-Muthanna Governorate. In order to study effect scheduling irrigation water and adding organic matter bio-bacterial fertilizer on concentration some nutrients wheat plant ( Triticum aestivum L.), carried out by distributing split plates using a randomized complete block design R.C.B.D. With three replications, included factors, as coefficients periods for first factor were set main panels at two levels (50 75%) capacity, factors biological fertilization secondary panels, treatments use The are (0 40 80 tons ha -1 ), while biofertilization levels, namely (adding bacterial vaccine not it). results indicated that treatment third level, O 2 , significantly superior rest treatments, highest values recorded nitrogen phosphorous potassium vegetative total, achieving an increase (12.05% 81.08 % 23.74%) sequentially, grains (86.11%), there no significant affecting content grains. Also, showed these, both with (5.51% 13.68%), (29.86% 17.11%) sequentially but regarding total grains, it affected it. While only adjective
