Abstract:

Field experiments was conducted to study the effect of weed control methods on wheat (Triticum aestivum L.) during Rabi seasons of 2014-15 and 15-16 at Agronomy Research Farm of NDUAT, Kumarganj, Ayodhya (U.P.). Pre-emergence application of pendimethalin + metribuzin (1.0 + 0.175 kg/ha) being at par with weed free and pendimethalin (1.0 kg/ha) followed by sulfosulfuron (0.025 kg/ha) significantly reduced the density of weeds as compared to other treatments. Pre-emergence application of pendimethalin +  metribuzin (1.0 + 0.175 kg/ha) significantly increased all growth and yield contributing characters, viz. plant height, dry matter accumulation, spikelength, grains/spike obtained with weed free. Among different herbicidal treatments, maximum grain and straw yields were recorded under pendimethalin + metribuzin (1.0 + 0.175 kg/ha) (4.22 and 5.70 t/ha, respectively). However, the highest benefit: cost ratio was recorded in weed free (1.97) followed by pendimethalin + metribuzin (1.0 + 0.175 kg/ha) (1.91).
