Abstract
The field experiment was laid out at Sorghum Research Station, VNMKV, Parbhani. Dist. Parbhani during kharif season of 2015 to study the “Integrated Nutrient Management in Kharif Sorghum (Sorghum bicolor L.)”. The experiment was laid out in randomized block design with three replications and variety CSH -16 as test crop along with nine (09) treatment combinations. The quantity of organic and inorganic fertilizer dose was calculated and applied in the plots as per the treatments. Sowing was done on 21th June 2015 by seeds are dibbling and distance between 45cm x 15 cm. The crop was harvested at physiological maturity and data on yield attributes and yield were recorded. The study revealed that the application of 75% RDN through inorganic fertilizer + 25% RDN through vermicompost + seed treatment with PSB + Azospirillum (T8) gave significantly higher GMR (76,068 ha-1), NMR (37,999 ha-1) and B:C ratio (2.07) over rest of the treatments, however it was at par with application of 75 % RDN through inorganic fertilizer + 25% RDN through FYM + seed treatment with PSB + Azospirillum (T7).
