Effect of establishment methods and weed management practices on weed control in barnyard millet under irrigated condition

Abstract

A field experiment was conducted during the kharif’2018 at Agricultural College and Research Institute, Madurai to find the suitable weed management practices for barnyard millet under irrigated condition. The results of the experiment revealed that the establishment method of machine transplanting was found to be better in minimizing the weed population followed by manual transplanting. Among the weed management practices, pre emergence application of pendimethalin @0.75kg aiha-1 at 3DAS/T fb one hand weeding at 30 DAS/T recorded lesser weed density, weed dry weight and weed index and higher weed control efficiency. Following this, the pre emergence application of pendimethalin @0.75kg aiha-1 at 3DAS/T fb one mechanical weeding using twin wheel hoe weeder at 30 DAS/T. The higher weed control efficiency(88.2%) and low weed index was registered with the pre emergence application of pendimethalin @0.75kg aiha-1 at 3DAS/T fb one hand weeding at 30 DAS/T under machine transplanted barnyard millet.
