YIELD OF MUNGBEAN VARIETIES AS INFLUENCED BY WEED MANAGEMENT PRACTICES

Abstract

A field experiment was conducted at the Agronomy field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period from March 2016 to May 2016 to study the efficacy of different weed control methods on growth and yield response of mungbean varieties under different weed management practices. The experiment consisted of two factors. Factor A: Mungbean variety (2 varieties): V1= BARI Mung 6 and V2= BARI Mung 8; Factor B: Weed management (5 treatments): T1= control (no weeding, no herbicide), T2= hand weeding at 20 and 40 DAS, T3 = Pre emergence herbicide (Panida) at 1-2 DAS, T4 = Pre emergence herbicide (Neon) at 2-3 DAS, and T5 = post emergence herbicide (Neon) at 10-15 DAS+hand weeding. The experiment was laid out in a factorial Randomized Complete Block Design (RCBD) with three replications. Results revealed that, the mungbean variety BARI Mung 6 stands superior than BARI Mung 8 in respect of dry matter content/plant (17.17 g and 17.02 g), pods/plant (15.71 and 15.54), seeds/plant (148.87 and 131.71), seed yield (1.94 t/ha and 1.61 t/ha) and 1000 seed weight (46.68 kg and 30.74 kg) respectively. Among weed management practices, maximum plant height (53.70 cm), dry matter weight/plant (17.96 g), pods/plant (18.31), seeds/plant (171.47) & maximum weed control efficiency (33.78 %) obtained from T3 replication. In intraction, the variety BARI Mung 6 weeded with T3 i.e. Pre emergence herbicide (Panida) at 1-2 DAS produced maximum seed yield (1.79 t/ha) as well as yield attributes. This treatment showed 2.29 % higher seed yield than control.
