Abstract

A field experiment was carried out during kharif, 2012 to summer, 2013 under rainfed condition in the organic block of Assam Agricultural University, Jorhat to find out the effect of different green manuring practices and other organic sources of nutrient on productivity of scented (joha) rice and their residual effect on linseed crop. Results revealed that though green manuring practice had no significant effect on yield and yield attributes of both scented (joha) rice and succeeding relayed linseed crop but higher values were recorded with the incorporation of dhaincha as in-situ green manuring in respect of all the yield attributes and yield of both the main and succeeding crops. Among various organic sources of nutrient, application of enriched compost produced the highest yield in both scented rice as well as linseed crop. The increase in grain yield of scented rice with enriched compost over the other sources of organic nutrient and control treatment ranged from 7.33 to 30.04 per cent. The corresponding increase in case of linseed crop ranged from 29.1 to 39.8 per cent which reflected better residual effects of both the sources of nutrient on linseed crop. The residual available nutrient contents in soil after harvest of linseed crop showed similar trends and increased all the major nutrients over their initial status.
