Effect of paddy straw incorporation along with nitrogen and phosphorus levels on yield and yield attributes in Rabi maize

A field experiment was conducted at the Regional Agricultural Research Station, Warangal, during the Rabi season of 2024-25, to study the effect of Paddy Straw with nitrogen and phosphorus levels on yield and yield attributes in maize. The experimental design was executed in a Factorial RBD comprised of 12 treatments replicated thrice. The results obtained that grain yield and Stover yield were significantly affected by both nitrogen and phosphorus management options, with the highest being found in the incorporation of crop residue along with 125% Recommended dosage of Nitrogen (30% basal, 30%15DAS, 35%Knee high stage, 30% taselling stage) and 100% RDP (Basal). Yield attributes like number of cobs per plant, number of rows per kernel, cob girth, cob length, Test weight (gms) were also highest in incorporation of crop residue along 125% recommended dosage of Nitrogen (30% basal, 30%15DAS, 35% Knee high stage, 30% taselling stage) and 100% RDP (Basal).
