Abstract
A pot experiment was conducted in the kharif season in 2024 and 2025 under controlled conditions to assess the combined effect of phosphorus levels and different irrigation regimes on yield and yield attributes. The 24 treatment combinations are - three irrigation level I1 (20 DAS), I2 (20+35 DAS) and I3 20+35+45 DAS) of crop water requirement, two rates of phosphorus P1 (low dose of P) and P2 (Sufficient P) and four verities IPM205-7, IPM 410-3, IPM2-3, IPM 512-1 were laid CRD (Completely Randomise Design) and replicated thrice. The highest seed yield per plant was obtained from the interaction P2Ã I3 and the lowest seed yield was in P1Ã I1. The interaction (P Ã I) effect showed that varieties receiving sufficient Phosphorus along with I3 irrigation exhibited superior performance, whereas low phosphorus levels with I1 were the limiting factor for yield and yield attributes. The findings highlight the importance of integrated phosphorus management and optimum irrigation scheduling for sustaining mung bean production under combined stress conditions.
