Abstract
A field experiment was conducted during rabi 2020-21 at Main Agricultural Research Station, Dharwad to study the effect of integrated weed management practices on growth and yield of buckwheat. Experiment consisted of 15 treatments where three herbicides viz., pretilachlor, atrazine and pendimethalin were applied as pre-emergent in first six treatments and next six treatments included application of herbicides as pre-emergent along with one hand weeding + one intercultivation at 25-30 DAS, weedy check and weed free check with three replications. Weed free check recorded significantly higher seed (728 kg/ha) and straw (1247 kg/ha) yield of buckwheat and it was at par with (T13) one hand weeding + one intercultivation at 25-30 DAS (674 kg/ha). All the growth and yield parameters followed the similar trend. Higher net returns (Rs.24583/ha) and B:C ratio (2.59) was recorded with treatment pretilachlor 50 EC @ 1.0 kg a.i. ha-1fb one intercultivation at 25-30 DAS (T10) and it was on par with, one hand weeding + one intercultivation at 25-30 DAS (Rs.23974/ha) and weed free check (Rs.23035/ha).
The weed control efficiency was highest with atrazine and pendimethalin sprayed treatments the growth and yield parameters, yield, net returns, B:C Ratio were lowest because of the severe phytotoxic effect of atrazine and pendimethalin on buckwheat which affected growth and plants remained stunted.
