Abstract:
Cowpea farming has been concentrated to the north India, and is usually cultivated with low level of technology. However, in recent years there has been an increase in the area planted with the crop in the central west using technology. Therefore, now need to study among other factors the chemical control of weeds. Two experiments were carried out with the aim of making a preliminary study during the vegetative phase of the cowpea, using the post-emergent herbicides in a field condition at the Rani Lakshmi Bai Central Agricultural University, Jhansi, India. The experimental design was completely randomized with four replications. The Relative Chlorophyll Content (SPAD index) was evaluated together with a visual evaluation of phytotoxicity. Promising results for selectivity in the cowpea were seen in relation to the herbicides under evaluation, whether applied prior to or after emergence of the crop. For weed control imazethapyr should be noted as potential post-emergent herbicides.
