​​Improved Herbicide Efficacy through Sole and Sequential Application of Herbicides for Higher Productivity of Urdbean (Vigna mungo) in Indian Semi-arid Tropics

Background: Weeds are major factor that leads to increase crop-weed competition and adversely effects of on growth, quality yield urdbean during kharif season. In the critical period for crop weed was first 25-30 days; yields can be reduced by 50-90%, if weeds were not controlled this period. As a result, successful management strategies achieve increased growth yield. Due ease, lower cost, timeliness success controlling weeds, progressive transformation agriculture involving intensive use herbicides has gained traction in recent years. Methods: During season 2019, field experiment undertaken at Agricultural Research Station Ummedganj, Kota, comprising ten strategies, laid out randomised complete block design with three replications. Result: Two hand weedings 20 40 DAS recorded significantly dry matter, higher control efficacy, ultimately culminating improved attributes yield, compared weedy check.
