摘要

豇豆(Vigna unguiculata L. Walp.)在尼日利亚的生产受到限制，主要是由于杂草和昆虫的侵害。在2020年早、晚两季分别评价了不同杀虫剂喷洒制度和杂草防治对豇豆产量的影响。两种杀虫剂喷雾在种植季后期都提高了生长和产量。然而，在早期种植季节，四种杀虫剂喷雾对豇豆的生长和产量都是最佳的。无论种植季节如何，苗期前施用异丙甲草胺或丙苯醚加人工除草可使豇豆的杂草密度和生物量减少71-80%，其生长和产量与无杂草控制相似。在季末，两个MWs使豇豆的生长和产量与无杂草对照相似。然而，在季初处理中，2 MWs导致产量比无草对照低51%。结果表明，早茬4次或晚茬2次杀虫与异丙甲草胺或丙苯醚配合施用MW可提高豇豆的产量。

Influence of insecticide spray regime and weed management methods on growth and yield of cowpea

ABSTRACT Cowpea (Vigna unguiculata L. Walp.) production in Nigeria is limited mainly due to weed and insect infestations. The effects of insecticide spray regime and weed control on the productivity of cowpea were evaluated in the early and late seasons of 2020. Two insecticide sprays produced increased growth and yield in the late cropping season. However, in the early cropping season, optimum growth and yield of cowpea were obtained with four insecticide sprays. Regardless of the cropping season, preemergence (PRE) application of metolachlor or propaben plus manual weeding (MW) provided 71–80% reduction in weed density and biomass and resulted in cowpea growth and yields similar to the weed-free control. In the late season, two MWs resulted in cowpea growth and yield similar to the weed-free control. However, in the early season treatment, two MWs resulted in 51% lower yield than the weed-free control. The results showed that four insecticide sprays in the early cropping season or two insecticidal sprays in the late cropping season integrated with metolachlor or propaben application plus MW improved the productivity of cowpea.
