Abstract


In the high rainfall areas of Western Ghats, Direct Seeded Rice (DSR) is an important rice cultivation method subjected to vagaries of rainfall. Resource Conservation Technologies (RCT’s) that conserve top soil, improve water holding capacity and nutrients cycling hold the key in improving productivity. Intervention isincorporating these technologies were adopted in 55 farmers’ fields during kharif of 2006-07, 2007-08 and 2008-09 in Khanapur taluk of Belgaum district in North Karnataka. A substantial improvement in the number of tillers, in spite of lower plant population and grains per panicle etc., were recorded due to adoption of resource conservation practices. Besides, there was a significant reduction in weed population and biomass. Rice yields were 15 per cent higher at much lower cost of cultivation. Zero Till practices reduced significantly seed rate, weed biomass etc. The profit under zero till was 28 per cent higher than that under farmers’ practices. However, when untimely and torrential rains affect timely sowing, dry sowing remained as an alternative option. Cultivation on sloppy land and terraces with small holdings, without heavy machine (tractor) drawn still provide scope for zero till practices and require lower energy for farmers with smaller holdings
