Abstract:
An investigation conducted on “Effect of weed management practices on weeds, growth and yield of potato (Solanum tuberosum L.) under organic farming ”. The field experiment was conducted at the Directorate of weed science Research (DWSR) Centre, College of Agriculture, (RVSKVV) Gwalior (M.P.) during the rabi season of 2016-2017.The experiment was laid out in randomized block design with 10 treatments replicated three times. The data pertaining to weed count recorded at 25, 40 DAP and harvest stage were subjected to square root transformation ,, Log x, and Log x+1 for statistical analysis. The dominant weeds flora observed in the experimental field were Chenopodium album, Anagallis arvensis, Spergula arvensis and Medicago hispida. Among treatments of organic weed control, Treatment T₆ (Two hand weeding at 20 and 40 DAP) observed most effective in controlling both broad and narrow leaf weeds, as well as total dry weight (g/m²) and these were significantly reduced weed population.
