Abstract:
A field experiment was carried out at research farm of I.G.K.V., Krishi Vigyan Kendra, Ajirma, Ambikapur (C.G.) during kharif season of 2022. The field experiment was laid out in a randomised block design with nine treatments in three replications. With the exception of pendimethalin at a dose of 1 kg a.i./ha, all herbicide treatments were effective in suppressing weeds, but pendimethalin had a phytotoxic effect on crop emergence relative to other treatments. Among herbicide weed control treatments, the lowest weed density and dry matter, higher growth characters and yield attributes and seed yield was recorded with two hand weeding at 15 and 30 DAS. It was at par with, sodium acifluorfen 16.5%(165g/ha) + clodinafop propargyl 8% (80 g/ha) (POE) at 20 DAS + one hand weeding, propaquizafop 2.5% + imazathapyr 3.75% 50+75 g/ha (POE) at 15 DAS + one HW at 30 DAS followed by quizalofop-p-ethyl @ 50 g/ha (POE) at 20 DAS + one HW at 40 DAS, imazathapyr 75 g/ha (POE) at 20 DAS + one HW at 40 DAS. In comparison to the other treatments, two HW recorded the greatest net income and B:C (34281 and 0.84, respectively).
