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 micronutrients in rice growing 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 micronutrients status in rice growing Alfisol. Lower micronutrients status of soil were noticed by 50%, 75% and 100% NPK than conjoint use of organic residue and fertilizer in soil. Significantly higher micronutrients content in soil 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 soil micronutrients status. 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.
