Productivity and economics of direct seeded rice (Oryza sativa L.)
Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 1
Abstract
A field study was conducted during Kharif season of 2011 and 2012, to evaluate direct seeded rice options as compared to transplanted rice with an objective to improve farm productivity and efficiency. Labour and cost saving of 97% and 80% were observed in direct seeded rice (DSR) as compared to manual puddled transplanted rice in sowing/transplanting. Tillage and crop establishment methods had a significant effect on rice yields. Yield of manual puddled transplanted rice was significantly higher (10-12%) than DSR during both the years. DSR consumed 12-17 percent less water as compared to puddled transplanted rice during 2011, whereas, it consumed 5-9 per cent more water as compared to puddled transplanted rice during 2012. When compared to manual puddled transplanted rice, a labour saving of 7-8 percent (overall) was observed in DSR during both the years. The B: C ratio was highest in DSR in zero till condition (1.74) as compared to manual puddled transplanted rice (1.62). The study showed that the conventional practice of puddled transplanting could be replaced with zero till DSR to save water and labour.
