“…The reduction of the weed population and biomass accumulation during crop growth period with stale seedbed technique which reduces the early seed flushes, in combination with mechanical weeding was found as effective as chemical control (Rie et al, 2007). Similar result was also observed by Verma et al, (2017) observed that among non -chemical methods of weed control, Sesbania co-culture followed by conoweeder (25 DAS) followed by 1 HW resulted lower weed density, lower weed dry matter accumulation, highest WCE, higher grain yield in aerobic rice. Effect of different weed management practices on weed dry matter accumulation (g/m 2 ) of different weed species at 60 days of crop growth is given in Table 2.…”
