Abstract: field experiment was conducted at Birsa Agricultural University, Ranchi during kharif season of 2012 and 2013 to study the efficacy of different weed control methods on weed dynamics and productivity of turmeric. The treatments comprised of integrated application of herbicides along with hoeing and straw mulch including weed free and weedy control. The results of pooled data revealed that application of metribuzin 0.7 kg ha-1 fb. by two hoeing being similar to weed free recorded reduced grassy and sedges weed at 30 DAP whereas, application of pendimethalin 1.0 kg ha-1 fb. two hoeing and application of pendimethalin 1.0 kg ha-1 fb. straw mulch 10 t ha-1 fb. one hand weeding were similar with weed free at 60 DAP. Application of pendimethalin 1.0 kg ha-1 fb. two hoeing similar to weed free recorded reduced total weed density and weed dry matter accumulation at 30 and 60 DAS. Application of metribuzin 0.7 kg ha-1 fb. by two hoeing recorded maximum yield (24.66 t ha-1) consequently higher gross return (616519 RS. ha-1) similar to metribuzin 0.7 kg ha-1 fb. straw mulch 10 t ha-1 fb. one HW, pendimethalin 1.0 kg ha-1 fb. two hoeing, pendimethalin 1.0 kg ha-1 fb. straw mulch 10 t ha-1 fb. one HW, atrazine 0.75 kg ha-1 fb. straw mulch 10 t ha-1 fb. one HW. Application of metribuzin 0.7 kg ha-1 fb. by two hoeing recorded 44.89 % and 134.86% higher yield than weed free and weedy check, respectively. Significantly maximum net return (504319 RS. ha-1) and B:C ratio (4.45) was recorded with application of Metribuzin 0.7 kg ha-1 fb. by two hoeing..
