Enhancing Profitability and Yield Potential of Weed Controlling in Green Gram (Vigna radiata L.) under Central Plains of Punjab

Abstract

Background: The first 30 DAS are crucial for the green gram crop while competing with crop weeds. Weed competition with light, water, nutrients and space has an impact on the development and growth of crops. Green gram yield loss is reduced by weed by about 50–80%. The switch of unwanted plant throughout the early stages of crop development is crucial. Methods: The methodology was lead in the two successive years of Kharif, 2021 and 2022 eight weed-controlling treatments were used in an RBD. The weed count of each plot remained measured in field using two quadrates measuring 25 cm x 25 cm. The weight of seeds, straw and dry biomass of weeds were measured by weighing balance. The collected samples of green gram were determined by yield attributes, yield and net monetary returns. Result: The consequences of finding are minimum weed population (6.01 m-2) and weed dry biomass (0.37 g m-2), maximum weed control effectiveness (87.51%), achieve yield characteristics for instance number of pods per plant (21.26), number of grains per pod (11.99), test weight (32.86 g), straw yields (24.48 q ha-1) were noted with Pendimethalin (1000 g ha-1) 2 DAS (PE) combined with Imazethapyr (50 g ha-1) 30 DAS (PoE). It can be used for extremely active weed control to upper seed yield (7.25 q ha-1) and maximum net profits (₹ 36738 ha-1) besides higher benefit cost ratio (1:96 respectively) of green gram.
