A field experiment was conducted at Research Institute of Organic Farming field unit, University of Agricultural Sciences, Gandhi Krishi Vignan Kendra, Bengaluru during Kharif (rainy season) of 2021 to evaluate different organic weed management methods in kodo millet (Paspalum scrobiculatum L.). The experiment was laid out in randomized complete block design with 12 treatments, replicated thrice. Hand weeding at 20 and 40 DAS was significantly superior in reducing the weed density (34.7 and 22 no./m2) and dry weight (4.8 and 5.3 g/m2) at 30 DAS and at harvest, respectively. Hand weeding at 20 and 40 DAS, stale seed bed technique fb inter cultivation twice at 25 and 45 DAS, inter cultivation at 25 DAS fb one hand weeding at 45 DAS, two mechanicals (cycle weeder) weeding at 20 and 40 DAS and kodo millet + fodder cowpea as intercrop with in-situ mulching on 35 DAS fb one intercultivation at 40 DAS registered 0.93, 0.76, 0.73, 0.68 and 0.67 t/ha grain yield, respectively as against the grain yield of 0.22 t/ha in weedy check. Among the weed control treatments, highest net returns of 34452/ha was recorded under weed free treatment while the highest B: C ratio (2.34) was recorded with both hand weeding at 20 and 40 DAS and stale seed bed technique fb inter cultivation twice at 25 and 45 DAS followed by two mechanicals (cycle weeder) weeding at 20 and 40 DAS (2.13).
