Abstract

In a field experiment, conducted during 2018-19 and 2019-20 at the Research Farm, Indian Agricultural Research Institute, New Delhi, factorial combinations of two levels of FYM (0, 10 Mg ha−1) applied to maize; four levels of nitrogen (0, 60, 120, 180 kg N ha-1) and three levels of phosphorus (0, 30, 60 kg P2O5 ha−1) applied to both maize and wheat and subsequent residual effects on green gram were compared. The RGR was at peak in maize at 29oC and in wheat at 12-13 oC. Integral of LAD and incidental solar radiation has significantly improved CGR. The LAD and CGR also shown significant relationship with grain/ seed yield in all three crops. Slightly higher NAR in combination with LAD and SRD can significantly contribute to overall performance of crops. Results indicated that variation in yield across years due to weather fluctuations, irrespective of treatments, was about 16.7 per cent in maize (kharif), 7.93 per cent in wheat (rabi) and 16.8 per cent in green gram (summer).
