Abstract:
Rainfed rice in eastern India suffers from frequent moisture stress leading to severe yield reduction due to uncertainty of rainfall coupled with inadequate field level rainwater conservation structures. Construction of RRIP (Runoff Recycling Irrigation Pond) is an alternative for the storage of excess rainwater during monsoon and reuse it as supplemental irrigation to the rice in the same season and pre-sowing irrigation to green gram crop in winter season. Simulation study revealed that RRIP of 17, 14 and 12% of total cultivated area were optimal for rice-green gram cropping system for 5, 10 and 15 cm ponding condition (PC), respectively. The above-mentioned optimal sizes of RRIP provides the benefit cost ratio (BCR), internal rate of return (IRR) and payback period (PBP) as 1.83, 20.23%, 13.19 years for 5 cm PC, 1.85, 22.96%, 11.04 years for 10 cm PC and 1.84, 21.45%, 10.99 years for 15 cm ponding condition.
