Abstract
A field experiment was conducted at a farmer field in Tiruchchirappalli District of Dharmanathapuram village, Tamilnadu during kharif 2016, to study the weed management practices in redgram based intercropping system. The experiment was laid out in split plot design with three replications. The treatments included five cropping systems viz., redgram + blackgram (1:1), redgram + blackgram (1:2), redgram + sesamum (1:1), redgram + sesamum (1:2) and sole redgram in the main plot. Five weed management practices were assigned to sub plot viz., unweeded control, two hand weeding on 15 and 30 DAS, pre-emergence application of pendimethalin 1.0 kg ha-1 followed by one hand weeding on 30 DAS, pre-emergence application of pendimethalin 1.0 kg ha-1 followed by post-emergence application of imazethapyr 0.75 kg ha-1 and post-emergence application of imazethapyr 0.75 kg ha-1 on 15 DAS followed one hand weeding on 30 DAS. Among the intercropping system redgram + blackgram (1:2) intercropping system checked growth of weed density, weed dry weight and higher weed control efficiency was higher in redgram + blackgram (1:2) intercropping system. Sole cropping of redgram increased its growth parameters and yield attributes of redgram Among the weed management practices, pre-emergence application of pendimethalin @ 1.0 kg + hand weeding on 30 DAS effectively control the weed count, weed dry matter production and there by favorably influenced the growth attributes, yield attributes and yield of redgram. Adoption of redgram + blackgram intercropping system raised as 1:1 ratio under additive series with pre-emergence application of pendimethalin @ 1.0 kg + hand weeding on 30 DAS fetched higher revenue.
