Conventional Weed Management Practice in Potato (Solanum tuberosum L.) with Optimum Time of Application

摘要

Field experiment was conducted during Rabi season of 2013-14 to evaluate the effect of weed management in potato with conventional method. There were five treatments viz. - Hand weeding @ 30 DAP, 40 DAP and 50 DAP, Weed free and weedy check. Among all treatments maximum tuber yield, plant height and nutrient uptake by potato haulm and tuber were recorded with weed free treatment followed by hand weeding at 30 DAP. While minimum tubers yield, plant height and nutrient uptake were recorded with weedy check treatment. Maximum numbers of weeds were recorded with weedy check treatment. Fumaria parviflora Lam. (dicot weed) and Chenopodium album L. (monocot weed) were found most prominent weed among different type of weed flora observed in experimental field.
