Abstract:
In the present study, different levels of inorganic fertilizers, FYM and biofertilizers were used as different treatments to evaluate the performance of gobhi sarson and soil properties. Application of 50% RDF + FYM @ 10 t/ha resulted into significantly higher seed, stover and biological yield over other inorganic fertilizers at different doses. 50% RDF + FYM @ 10 t ha^-1also caused significantly higher organic carbon content in soil than all other treatments. Maximum reduction to soil pH was found in 50% RDF + FYM @ 10 t ha^-1. Available N, P, K and S in soil were also significantly higher in 50% RDF + FYM @ 10 t/ha than all other treatments. Microbial count and enzymatic activity were most favorably affected by 50% RDF + FYM @ 10 t ha^-1. Maximum positive effect on yield and soil properties among different biofertilizer treatments was shown by consortium treatment followed by Azotobacter + PSB, Azotobacter, PSB and no biofertilizer application. Thus application of consortium and integration of FYM affected the gobhi sarson yields most favourably which can be attributed to their significant effect of soil chemical properties.
