Effect of Herbicidal Weed Management on Yield Attributes, and Yield of Kodo (Paspalum scrobiculatum L.)

Abstract

The present experiment was carried out at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Kharif seasons 2021 and 2022. The field experiment was laid out with Indira Kodo 1 variety as test crop in Randomized block design (RBD) with 10 treatment and 3 replications. Results of the experiment revealed that, different weed management practices affected all the yield attributes and yield viz., Number of Ear Head, Length of Ear Head (cm), Number of Seeds Ear Head, Ear Head Weight (g), Test Weight (g), Harvest Index (%) and were significantly higher under Pyrazosulfuron ethyl 10 % 20 g/ha (PE) fb Chlorimuron ethyl 10 % + Metsulfuron methyl 10 % 4 g/ha (PoE) which was followed by Hand weeding twice at 20 and 40 DAS. All the yield attributes and seed yield were equally highest in both the kharif seasons i.e. seed and straw yield of kodo (Mean viz., 2044 and 4073 kg ha-1) were also found maximum under the treatment Pyrazosulfuron ethyl 10 % 20 g/ha (PE) fb Chlorimuron ethyl 10 % + Metsulfuron methyl 10 % 4 g/ha (PoE) which was significantly highest in comparison to the different weed managements treatments.
