Abstract:
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. All the integrated weed management practices gave more tuber yield than weedy check. Amongst different weed control treatments, two hand weeding (HW) at 20 and 40 DAP was the most effective treatment for reducing weed population along with dry weight of weeds so consequently improving the growth. The findings revealed that the maximum potato yield (22.38 q/ha) and net return (Rs 245677) were obtained from one HW at 20 and 40 DAP, followed by one at 20 DAP + straw mulching 5 t/ha at 25 DAP. In the scarcity of labours, the farmer may go for the second option i.e., HW at 20 DAP + straw mulching 5 t/ha at 25 DAP or straw mulching 5 t/ha at 5 DAP. The B:C was obtained higher (2.51) in HW at 20 and 40 DAP followed by HW at 20 DAP + straw mulching 5 t/ha at 25 DAP.
