Abstract :

The purpose of this study was to evaluate the effect of bacterial chemical integrated feeding system on yield and yield components of wheat phonological growth stages. Treatments included: Two levels of bio fertilizers B1: Seed inoculation with bio fertilizer, B2: Sterile inoculated seed, three levels of N fertilizer N1: Nitrogen fertilizer application 20% less than recommended, N2: Nitrogen fertilizer equal to recommended, N3: Nitrogen fertilizer application was 20% more than recommended in 4 replications in a completely randomized block design. The results showed that using B2N2 treatment, grain yield was 16.14% and 16.36% higher than B2N1 and B2N3, respectively. By applying B2N2 treatment, 1000-grain weight was higher than B2N1 and B2N3 as 11.05% and 6.92%, respectively. Grain yield was increased with simple nitrogen fertilizer treatment by fertilizer application 20% less than recommended at 12.20% and by application of fertilizer by 20% higher than recommended by 16.67% which was significant. The effect of bio fertilizer and nitrogen fertilizer treatments on bio farm inoculation and nitrogen application on sterile inoculation was quite noticeable. Therefore, bio farm fertilizer application and nitrogen fertilizer application are based on fertilizer recommendation to improve yield of wheat and its components. This highlights the importance of the bacterial chemical fusion system at different stages of wheat growth.
