Influence of different rice establishment methods on yield, labour productivity, economic water productivity and energetics in CO (R) 51

Afield experiment was conducted at wetland farm of Tamil Nadu Agricultural University, Coimbatore during kharif 2017 to study the influence of different rice establishment methods on yield, labour productivity, economic water productivity and energetics in CO (R) 51. The experiment was carried out with five transplanting and four direct sown methods of establishment. The results revealed that crop established through square planting (SRI) with single seedling recorded significantly higher grain yield (6860 kg/ha), straw yield (10195 kg/ha), total output energy (228092 MJ), net energy gain (210452 MJ) and energy use efficiency (12.9%) compared to other establishment methods. Among the different rice establishment methods labour productivity (2.38) and economic water productivity (Rs 93.8/ha mm) were registered higher in drum seeding method under pudddled condition.
