Effect of Crop Establishment Methods on Productivity, Energetics and Economics of Rice

摘要

Field experiments were conducted during summer and kharif seasons of 2001 at Agricultural Research Station, Honnavile, University of Agricultural Sciences, Bangalore. Pooled data of two seasons indicated that drum seeding with application of pre-emergence herbicide pretilachlor + safener at 1 L ha~(-1) on 4 DAS followed by one hand weeding at 30 DAS recorded significantly higher grain yield (7061 kg ha~(-1)), net income (Rs. 25208 ha~(-1)) in addition to higher energy output (219610 MJ ha~(-1)) and energy use efficiency (9.93). Days to fifty per cent flowering and maturity in direct seeded rice was 8-9 days early compared to transplanted crop.
