摘要

采用随机区组设计、8个杂草管理处理和3个重复，于2022年秋季在印度旁遮普省帕格瓦拉Lovely专业大学农学系进行了田间试验。探讨豇豆(Vigna unguiculata, L.)杂草防治措施的经济性和有效性。杂草控制技术对杂草限制有很大影响。苗期前施用0.70 kg/ha喷施对二甲甲烷配合手除草，在作物生长的不同阶段，杂草密度和生物量均较低，防杂草效果较好。这证实了出苗期前施用除草剂可以有效调控早出苗期杂草，实际控制杂草可以提高产量和B: C比。

Effect of herbicides on weed control efficiency and Yield Response of Kharif Cowpea (Vigna unguiculata L.) in sandy loam soils of Punjab

A field experiment using a randomized block design, eight weed management treatments, and three replications was carried out in the kharif of 2022 at the Division of Agriculture, Lovely Professional University, Phagwara, Punjab, India. To determine the economics and effectiveness of weed control measures for managing weeds in cowpea [Vigna unguiculata (L.). The weed control techniques had a big impact on the weed restrictions.With pre-emergence application (PE) of pendimethalin 0.70 kg/ha combined with hand weeding, the weed density and biomass and greater weed control efficiency were consistently inferior at different stages of crop growth. This confirmed that pre-emergence herbicide application could effectively regulate the weeds emerging early in the season, and the actual controlling of weeds by it led to higher yield and B: C ratio.
