Abstract:

Field experiment was conducted during rabi 2015 at Tamil Nadu agricultural university, AC & RI, Madurai to study yield and economics of irrigated blackgram under lay by method of pre-emergence herbicide application. Results indicated that lay by method were found to superior to individual application with respect to weed control. Among the lay by treatments pre emergence application of pendimethalin at 1.0 kg ha-1 on 3 DAS followed by hand weeding on 20 DAS and sand mix application of pendimethalin at 1.0 kg ha-1 immediately after hand weeding significantly reduced the weed growth and recorded higher seed yield (1087 kg ha-1), net monetary returns (Rs. 40546 ha-1) and B: C ratio 2.86. The results significantly superior over rest of the treatments. Uncontrolled weed growth caused reduction in seed yield of blackgram.
