Abstract: A field experiment was conducted during rabi season of 2016-17 at Research cum Instructional Farm of IGKV, Raipur, Chhattisgarh to study the effect of weed management practices on growth Weeds, yield and economics on linseed (Linum usitatissimum L). Experiment was laid out in Randomized Block Design with three replications. The treatments comprised of ten weed management practices viz, metribuzin + oxyflurofen @ 250 g + 125 g ha-1 as pre-emergence 1 DAS (T1), oxyflurofen @ 125 g ha-1 as pre-emergence at 1 DAS (T2), oxadiargyl @ 80 g ha-1 as pre-emergence at 1 DAS (T3), imazethapyr 10 EC @ 75 g ha-1 as post-emergence at 22 DAS (T4), metsulfuron-methyl @ 4 g ha-1 as post-emergence at 22 DAS (T5), isoproturon @ 1 kg ha-1 as post-emergence at 22 DAS (T6), isoproturon + metsulfuron-methyl @ 1 kg + 4 g ha-1 as post-emergence at 22 DAS (T7), pendimethalin + fb metsulfuron-methyl @ 1 kg + fb 4 g ha-1 as pre + post-emergence at 1 and 22 DAS (T8), and hand weeding twice at 21 and 45 DAS (T9), weedy check (T10). Hand weeding twice 21 and 45 DAS (T9) followed by isoproturon + metsulfuron-methyl @ 1 kg + 4 g ha-1 as post-emergence (T7), metsulfuron-methyl @ 4 g ha-1 as post-emergence (T5), were most appropriate for reducing weed density, weed dry matter production, lowest weed growth rate. Whereas weed index recorded minimum in hand weeding twice at 21 and 45 DAS (T9). The economic returns in terms B: C ratio was maximum under metsulfuron-methyl @ 4 g ha-1 as post-mergence (T5).
