Abstract: A field experiment was conducted during kharif, 2016 at Agronomy Farm, College of Agriculture, Dhule. To evaluate the optimum doses and efficacy of new molecules of herbicides used alone or in combination with cultural methods for better management of weeds in pigeonpea. Ten treatment were replicated thrice in Randomized Block Design (RBD). Significantly higher seed and straw yield of pigeonpea was recorded in the integrated weed management treatment which received application of pendimethalin @ 1.0 kg ha-1as PE + imazethapyr 35 EC + imazamox 35 EC @ 0.075 kg ha-1 (20 DAS) fb HW at 40DAS (2215 and 5610 kg ha-1, respectively). Growth parameters viz., plant height (215.12 cm), number of primary branches (19.10), total dry matter (203.14 g plant-1) and yield parameters like number of pods plant-1(160 plant-1) and 100 seed weight (9.99 g) of pigeonpea were also increased significantly with pendimethalin @ 1.0 kg ha-1as PE + imazethapyr 35 EC + imazamox 35 EC @ 0.075 kg ha-1 (20 DAS) fb HW at 40DAS as compared to weedy check. Combination of pre and post emergence herbicides along with manual method of weed control has resulted in significant increase in growth and yield of pigeonpea.
