Early sowing of rice by 20 June produced significantly the highest grain yield followed by normal (5 July) and late sowings (20 July) and the yield of its stubble crop also followed the similar trend. The combined grain yields of early sown rice-ratoon and the rice equivalent yield (REY) of early sown green gram was significantly higher by 8.64% and 23.74% than normal and late sowings, respectively in rice-ratoon-green gram system. The combined REY in modified system of rice intensification (MSRI)-ratoon-green gram system was 7.33% and 33.22% higher than system of rice intensification (SRI)-ratoon-green gram and best management practice (BMP)-ratoon-green gram system, respectively. The system with hybrid rice Ajay had significantly higher REY than the system with high yielding rice cv. Tapaswini. The system productivity under early sowing of rice and green gram was significantly higher by 8.64% and 23.76% than normal and late sowings of such crops. To get maximum dividend in terms of net return, benefit-cost ratio and system profitability with minimum cost of production, early sowing of hybrid Ajay under MSRI followed by its ratoon and early sown green gram in sequence should be given first priority in east and south east coastal plain zone of Odisha, India having dwindling hybrid rice area.
