Abstract:
A field experiment was conducted at Experimental farm, Faculty of Agriculture, Annamalai University, Annamalai Nagar during <em>kharif</em> 2013 with an objective to study the effect of weed management practices and crop establishment methods in irrigated redgram. The experiment was laid out in split plot design with three replications. The treatment comprised of two crop establishment methods viz., transplanting and direct sown, were assigned to main plot and in sub plot treatments consist of pre-emergence application of herbicides alachlor and pendimethalin 1.0kg ha<sup>-1</sup> each in combination with one hand weeding on 40 DAS and pre emergence application of alachlor and pendimethalin with post-emergence herbicide Imazethapyr1.0kg ha<sup>-1</sup>on 25 DAS. In addition to this two hand weedingon 20 and 40 DAS and un weeded control. The obtained results revealed that among the weed management practices pre-emergence application of pendimethalin 1.0kg ha<sup>-1</sup> followed by hand weeding on 40 DAS effectively controlled the weed density, dry weight and higher weed control efficiency that favourably increased the yield attributes and yield of redgram. Transplanted redgram increased the he yield attributes of redgramviz., total number of pods plant<sup>-1</sup>, number of seeds plant<sup>-1</sup> and seed yield than direct sown method.
