Abstract:
The escalating demands of a growing population necessitate not only the sustenance of wheat production but also its further augmentation through high-yielding approaches mainly effective weed management. Two field experiments to evaluate different doses and method of application of Metribuzin on growth and yield of wheat crop under zero and conventional tillage systems was conducted at Agronomy Research Farm of CCS Haryana Agricultural University, RRS, Kaul, during rabi season of 2021-22 and 2022-23. POE metribuzin 350 g ha^-1 urea-mix broadcast at 35 DAS with PDN enhanced the growth and productivity of wheat and registered significantly taller height of plants, no. of tillers mrl^-1 and grain yield (57.35 and 54.10 q ha^-1 in zero tillage; 61.40 and 58.04 q ha^-1 in conventional tillage system during 2021-22 and 2022-23, respectively) and lowest grain yield was observed with pre-emergence application of Metribuzin at a dose of 210 g ha^-1. Additionally, the application of pinoxaden, a post-emergence herbicide, along with different metribuzin treatments led to an increase in wheat grain yield under both tillage systems (51.37 and 48.12 q ha^-1 in zero tillage; 53.62 and 50.26 q ha^-1 in conventional tillage system during 2021-22 and 2022-23, respectively) as compared to no PDN (48.42 and 45.17 q ha^-1 in zero tillage; 50.13 and 46.77 q ha^-1 in conventional tillage during 2021-22 and 2022-23, respectively).
