A field experiment was carried out at Research Farm, Department of Agronomy, G.H. Raisoni University, Chhindwara, Madhya Pradesh during Rabi season 2019-20, on effect of pre and post emergence herbicides on growth, yield and economics of wheat. Nine herbicide treatments comprised of post emergence application of Pendimethalin @1.0 Kg a.i. ha-1 as pre-emergence 2 DAS, Metsulfuron methyl @ 3 and 4 g a.i. ha-1 POE at 18 DAS, Metribuzin @ 131 and 175 g a.i. ha-1 POE at 18 DAS, 2,4-D @ 563 and 750 g a.i. ha-1 POE at 18 DAS, weed free and weedy check. The experiment was laid out in randomized block design with thrice replication. The experimental results revealed that the growth attributing characters of wheat crop viz., plant height and dry matter accumulation plant-1. Maximum grain yield (47.17 q ha-1), straw yield (69.22 q ha-1), gross monetary returns (95738 Rs. ha-1), net monetary returns (58166 Rs. ha-1) and benefit cost ratio (2.55) were recorded under application of pendimethalin @ 1.0 Kg a.i. ha-1 as pre-emergence at 2 DAS as compared to rest of the treatments.
