Abstract
A field experiment was carried out in the farmers’s field at Sivapuri village, Chidambaram Taluk, Cuddalore district to study the effect of cultural and chemical weed management practices on growth and yield parameters of irrigated cowpea. The cowpea variety Co (CP) 7 was used for this study. There were altogether nine treatments including the pre-emergence herbicide Pendimethalin and post-emergence herbicide Quizalofop-ethyl in combination with intercultivation at 20 DAS. In addition, two hand weeding at 20 and 40 DAS were also compared with Unweeded control. The growth and yield parameters of cowpea were significantly influenced by all the treatments. Among the treatments, Application of Pendimethalin @ 0.5 kg ha-1 as pre-emergence + intercultivation by star weeder at 20 DAS significantly and regarded as the best treatment. It is followed by two hand weeding at 20 and 40 DAS.
