The effect of pre and post-emergence herbicide application on the growth and yield of late-sown wheat (Triticum aestivum L.)

Abstract

During the Rabi season of 2022-2023, a field experiment was undertaken at the Department of Agriculture's Research Farm at Maharishi Markandeshwar University in Mullana, Ambala Haryana during Rabi season 2022-2023. The current study was aimed to evaluate effect of pre and post-emergence herbicide application on the growth and yield of late-sown wheat (Triticum aestivum L.). The experiment was designed in a Randomized Block Design (RBD) with eight treatments. Different pre and post herbicides such as T1: Pendimethalin 1000 ml/ha, T2: Clodinafop Propargyl 60 g/ha, T3: 24, D (Amine salt) 750 ml/ha, T4: Pendimethalin 1000 ml/hafb Metribuzin 50 g/ha, T5: Pyroxasulfone 127g/ hafbsulfosulfurone 25 g/ha, T6: Metasulfone 4g/ha+ Metribuzin 50 g/ha, T7: Two hand weeding (20 and 40 DAS) and T8: Weedy check. All herbicidal treatments considerably decreased weed population, however the magnitude of effectiveness varied amongst herbicides. T4: Pendimethalin 1000 ml/ha fb Metribuzin 50 g/ha emerged as most effective herbicide treatment showing highest weed control efficiency.
