Abstract:
A field experiment was conducted to study the, “Effect of zero budget natural farming on organic carbon and microbial population of wheat”. The study was accomplished during rabi season of 2019-20 and 2020-21 at Research Farm, College of Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M. P.). The experiment was laid out in a Randomized Block Design; comprising of fifteen treatments. The results indicated that significantly higher microbial population viz., Bacteria (x10⁵ cfu g^-1 soil), actinomycetes (x10³ cfu g^-1 soil) and fungi (x10⁴ cfu g^-1 soil) were found with the treatment T₁₂: Beejamrutha + Jeevamrutha + Panchgavya (1000 ml + 500 l + 15 lit. ha^-1) and T₁₃: Beejamrutha + Panchgavya + Ghanajeevamrutha (1000 ml + 15 lit. + 25 kg ha^-1) at par with T₁₄: Ghanajeevamrutha + Jeevamrutha + Beejamrutha (25 kg + 500 l + 1000 ml ha^-1). No significant effect of T₁₄: Ghanajeevamrutha + Jeevamrutha + Beejamrutha (25 kg + 500 l + 1000 ml ha^-1) were observed on organic carbon content in soil. The lowest values for bacteria (x10⁵ cfu g^-1 soil), actinomycetes (x10³ cfu g^-1 soil), fungi (x10⁴ cfu g^-1 soil) and organic carbon content were recorded under treatment of T₁₅: 100% RDF (N:P:K 120:60:40 kg ha^-1). Application of liquid organic manure failed to generate any significant effect on soil physico-chemical properties.
