abstract
A field experiment was conducted at the Research farm of the Department of Agriculture, Maharishi Markandeshwar University, Mullana, Ambala during Rabi season of 2022. The present investigation entitled "Effect of various herbicides for weed control in late sown wheat (Triticum aestivum L.)". Experiment was laid out in randomized block design with three replications. The experiment consisted of eight treatments viz Pendimethalin 1000 ml ha^-1, Pendimethalin 1000 ml ha^-1 fb Metribuzin 250g ha^-1, Clodinafop propargyl 400g ha^-1, 2,4-D (amine salt) 750 ml ha^-1, Metribuzin 250g ha^-1, Sulfosulfuron 35g ha^-1, Two Hand weeding (20 and 40 DAS) and weedy check. Result revealed that Pendimethalin 1000 ml ha^-1 fb Metribuzin 250g ha^-1 was found effective to control weed populations and recorded (47.30 q/ha) the highest grain yield. The highest test weight (40.26g) was recorded in Pendimethalin 1000 ml ha^-1 fb Metribuzin 250g ha^-1. The highest weed control efficiency (75.10%), lowest weed dry weight (4.60 g) and minimum weed density (3.53 m^-2) at tillering stage was recorded in Pendimethalin 1000 ml ha^-1 fb Metribuzin 250g ha^-1 among all the treatments.
