Effect of Different Herbicidal Weed Management on Yield and Economic of Ragi

Abstract

The present experiment was carried on the performance of ragi 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 ragi (Indira ragi 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 2021 and 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 % and economics of different herbicide application of ragi reveals that T9: Green manuring up to 40 DAS required highest cost of cultivation (Mean viz., 39676Rs. ha-1) than hand weeding twice 20 and 40 DAS (Mean viz., 34876Rs. ha-1) and lowest cost of cultivation in control (Mean viz., 22876Rs. ha-1). Gross return, net return and B: C ratio was significantly higher under (T5) Pyrazosulfuron ethyl 10 % 20 g/ha (PE) fb Chlorimuronethyl 10 % + Metsulfuron methyl 10 % 4 g/ha (PoE). Seed and straw yield of finger millet (Mean viz., 2719 and 8167 kg ha-1   and 24.98%), Gross return, net return and B: C ratio (Mean viz., 94573, 68950Rs. ha-1 and 3.69) while minimum was recorded under T10: control during both years and on mean value.
