Response of Seed Yield and Its Components of Bread Wheat to Different Level of Combination Chemical and Biological Fertilizer and Several Type of Application Fertilizer

Application of bio-fertilizers, especially the plant growth promoting bacteria, is most important strategy for the integrated management of the plant nutrition in the sustainable agriculture system with sufficient input.
Current study was conducted to investigation the effect of different rate of combination fertilizer and biological fertilizer and type of application biofertilizer on crop production of Wheat.
This research was carried out via factorial experiment based on randomized complete blocks design with three replications along 2020-2021 year. The treatments included different rate of combination Nitrogen fertilizer and Biofertilizer (Fla Wheat) (a1: 100% nitrogen with nonuse of Fla Wheat as control or N100/F0, a2: 70% Nitrogen with Fla Wheat or N70/F1, a3: 40% Nitrogen with Fla Wheat or N40/F1) and several methods of applying biofertilizer (Fla Wheat) (b1: 100% Seed treatment, b2: 100% by irrigation, b3: 50% seed treatment with 50% by irrigation).
According result of analysis of variance effect of different level of fertilizer combination, method of application fertilizer (instead number of spikelet per spike) and interaction effect of treatments (instead number of spike per m2 and number of spikelet per spike) on all measured traits was significant.
Mean comparison result of different level of fertilizer combination showed that maximum amount of seed yield (7032.1 kg.ha-1), biologic yield (15315 kg.ha-1), Harvest index (45.89%) number of spike per m2 (384.84), number of spikelet per spike, number of seed per spikelet (18.02), number of seed per spike (2.23) and 1000-seed weight (40.26 gr) was noted for N100/F0 and minimum of those belonged to N40/F2 treatment.
As for Duncan classification made with respect to different level of Method of application fertilizer the highest and lowest amount of measured traits was for M3 and M2 treatment.
Generally result of this study revealed to save energy and produce economic yield application 70% Nitrogen with biofertilizer (Fla Wheat) at 50% seed treatment with 50% by irrigation recommended.
