Abstract:
A field experiment was conducted during 2020 at Agricultural College Farm, Bapatla to study the effect of organics and biofertilizers on soil biological properties by rabi sorghum. Significantly highest enzyme activity (dehydrogenase and urease) and microbial population (bacteria, fungi and actinomycetes) were recorded in the treatment received 100% RDF + FYM @ 10 t ha^-1 + Azospirillum @ 5 kg ha^-1 + PSB @ 5 kg ha^-1 (T₂) at blooming and harvest stage and it was on par with treatments 100% RDF + Vermicompost @ 3 t ha^-1+ Azospirillum @ 5 kg ha^-1 + PSB @ 5 kg ha^-1 (T₃) and 100% RDF + Neem cake @ 500 kg ha^-1+ Azospirillum @ 5 kg ha^-1 + PSB @ 5 kg ha^-1 (T₄). The lowest was observed with the treatment receiving 100% RDF (T₁) at blooming and harvest stage in soil.
