Effect of different herbicidal weed management on yield and economic of kodo (Paspalum scrobiculatum L.)

The present experiment was carried on the performance of kodo at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Kharif seasons 2021 and 2022 The field experiment was laid out of kodo (Indira kodo 1) was growing variety for test crop in Randomized block design (RBD) with 10 treatment and 3 replications. The crop was sown manually on seedcum fertilizers 1 July 2021and 2 July 2022 after the onset of monsoon. The result of the experiment revealed that, different weed management practices on seed yield, straw yield, harvest index (%), economics of different herbicide application of kodo reveals that T₉: Green manuring up to 40 DAS required highest cost of cultivation than hand weeding twice 20 and 40 DAS and lowest cost of cultivation in control. Seed yield, straw yield, harvest index (%) (Mean viz., 2044 and 4073 kg ha^-1 and 33.41), gross return (Mean viz., 61060Rsha^-1), net return (Mean viz., 36354Rs ha^-1) and B: C ratio (Mean viz., 2:46) was significantly higher under(T₅) Pyrazosulfuron ethyl 10% 20 g/ha (PE) fb Chlorimuronethyl 10% + Metsulfuron methyl 10% 4 g/ha (PoE) while minimum was recorded under T₁₀: control during both years and on mean value.
