Zero till planting an important component of conservation agriculture is found to be a potential alternative to conventional full tillage cultivation of mustard in north eastern coastal plain zone of Odisha. Farmers' participatory field trials were conducted to evaluate zero till cultivation along with different weed management practices against farmers’ practices during 2014-15 and 2015-16 in mustard crop in rice-mustard cropping system. Maximum net return of ?12750 per ha was obtained from ZT+Post herbicides significantly more than all other treatments. Grain yield and yield attributes of mustard were better under conventional tillage with line planting (T3) over other practices. ZT treatments, ZT+Post and NS+ZT produced similar grain yield as obtained by farmers’ practice of CT+BS (T5). Even though CT+LS+BS (T3) registered better grain yield, the net income (?11289) was found to be lesser than that under ZT+Post (?12750). Greater save in cost of cultivation and energy were observed under zero till planting with use of herbicide as post emergence or pre-plant application associated with higher profits. No till planting without herbicide application was found to be unprofitable during the experimentation period
