Abstract

The experiment was performed in a randomized block design in two blocks of Hamirpur district of Himachal Pradesh with five treatments during both kharif and rabi seasons 2022 and 2023 to study the effect of post-emergence herbicides on growth and productivity of maize and wheat. The post-emergence application of herbicides tembotrione 120 g/ha and topramezone 25.2 g/ha were compared with the farmers' practice during kharif while the herbicides applied in kharif were rotated with two herbicides in wheat viz., clodinafop propargyl + metsulfuron methyl and metribuzin during rabi season. Both herbicides (tembotrione and topramezone) significantly reduced total weed count and dry weight than farmers' practices across years and locations besides significantly enhanced plant height, dry matter accumulation and crop growth rate. In both the blocks, significantly higher grain yield was recorded with tembotrione, which was at par with topramezone irrespective of different herbicides used in previous crop.
