Abstract:
The field experiment was carried out at Potato Research Station, Mainpat, IGKV (C.G.) during rabi 2019-20 and 2020-21.An experiment entitled “Influence of weed management practices on growth and yield of rabi potato under Northern Hill Zone of Chhattisgarh” was laid out in Randomized Block Design having eight weed management practices viz. W₁-Metribuzin 70% WP @ 0.75 kg ha^-1, PE, W₂-Pendimethalin 38.7% CS 1.0 kg ha^-1, PE,W₂-Oxyflourfen 23.5% EC @ 0.1 kg ha^-1, PE, W₄-Atrazine 50% WP @ 1.0 kg ha^-1, PE, W₅-Paraquat 24% SL @ 0.5 kg ha^-1 early POE after 10% germination of potato, W₆-Mechanical weeding 40 DAP, W₇-Hand weeding 20 and 40 DAP and W₈-Unweeded check. The result of the experiment revealed that, all the growth parameters i.e. emergence, plant height, number of shoots plant^-1, shoot fresh and shoot dry weight plant^-1, quality parameter and yield attributes and yield were maximum under hand weeding (20 and 40 DAP). Total tuber yield was increased 71% over the unweeded check.
