Abstract:
An experiment was conducted during Kharif, 2019-20 at the Research Farm of Department of Agronomy, Dr. BSKKV., Dapoli, Maharashtra, to study the “Effect of crop residues and fertilizer on soil properties and yield of rice in Alfisol”. The study was taken on ex-situ incorporation of crop residue along with fertilizers in soil for development of soil fertility and crop productivity. The results emerged out indicated that the application of rice straw @ 2.5 t ha-1 + ain leaf residue @ 2.5 t ha-1 along with 100% NPK was found to be significantly beneficial for improving soil properties and yield of rice in Alfisol. Lower soil properties and yield were noticed by 50%, 75% and 100% NPK than conjoint use of organic residue and fertilizer in soil. Significantly higher yield and yield attributes were also observed by the application of rice straw @ 2.5 t ha-1 + ain leaf residue @ 2.5 t ha-1 along with 100% NPK over 50%, 75% and 100% NPK alone. Use of crop residue in conjunction with chemical fertilizers can improve yield and yield attributes. Thus, integrated use of rice straw @ 2.5 t ha-1 + ain leaf residue @ 2.5 t ha-1 and 100% NPK was found to be feasible and proved overall superior impact on rice crop in Alfisols.
