Abstract:
A field trial was conducted on maize during Kharif season 2021 to evaluate the Influence of crop residues and bio- decomposer on soil Physico-chemical properties, growth and yield of Maize (Zea mays L.) var. K-25(Kanchan) in sandy loam soil. The experiment was laid down in randomized block design with different treatments crop residues (Wheat and Mustard) treated with and without Bio-Decomposer replicating thrice. Various treatments doses RDF (N 120 kg ha^-1, P₂O₅ 60 kg ha^-1, K₂O 40 kg ha^-1), Wheat and Mustard crop residue 5 t ha^-1 and bio-decomposer 49.42 g ha^-1. T₉ (Wheat residue and mustard residue treated with bio-decomposer + RDF @ 100%) that showed the highest yield and gave the best results with respect to highest grain yield 37.78 q ha^-1. In post-harvest soil properties, the important parameter on Physico-Chemical properties on maize crop water holding capacity (%) 55.59 in 0-15 cm and 54.60 in 15-30 cm depth, Organic Carbon (%) 0.579 in 0-15 cm and 0.518 in 15-30 cm depth, Available Nitrogen (kg ha^-1) 243.99 in 0-15 cm and 241.89 in 15-30 cm depth, Phosphorus (kg ha^-1) 30.52 in 0-15 cm and 28.90 in 15-30 cm depth, Potassium (kg ha^-1) 128.62 in 0-15 cm and 125.78 in 15-30 cm depth was found Significant.
