The experiment was conducted in Department of Agronomy, College of Agriculture (RVSKVV), Gwalior (M.P.) during the rabi season of 2017-2018. The trial was laid out in a randomized block design replicated three times with 10 treatments namely T1 [White plastic mulch (50 micron)], T2 [Black plastic mulch (50 micron)], T3 (Straw mulching @ 5 t/ha at 5 DAP), T4 (One HW at 20 DAP + Straw mulching @ 5 t/ha at 25 DAP), T5 (2 HW at 20 & 40 DAP), T6 (One hand hoeing at 20 DAP), T7 (Hoeing at 20 DAP & one HW at 40 DAP), T8 [Recommended herbicide (Metribuzine 0.5 kg /ha as PE)], T9 [Recommended herbicide (metribuzine 0.5 kg /ha as PE)+ 1 HW at 40 DAP] and T10 (Weedy check). All the integrated weed management practices gave more tuber yield than weedy check. Amongst different weed control treatments, Two hand weeding at 20 & 40 DAP was the most effective treatment for reducing weed population and weed dry weight and improving the growth. On the basis of above findings, it may be concluded that the maximum potato yield and net return were obtained from Two H.W. 20 & 40 DAP, followed by One H.W. at 20 DAP + Straw mulching @ 5 t/ha at 25 DAP. In the scarcity of labourer, the farmer may chose the second option i.e., One H.W. at 20 DAP + Straw mulching @ 5 t/ha at 25 DAP or Straw mulching @ 5 t/ha at 5 DAP. B:C ratio was obtained higher in Two H.W. 20 & 40 DAP followed by One H.W. at 20 DAP + Straw mulching @ 5 t/ha at 25 DAP.
