Abstract:
A field experiment was carried out during the summer season of 2019 on vertisol soil at Navsari Agricultural University, Navsari to study the integrated efficacy of various herbicides applied as pre and post-emergence in cowpea (Vigna unguiculata L.). Among the different weed management practices, application of Pendimethalin 750 g/ha (PE) fb HW at 30 DAS found superior while weed free (2 HW at 20 and 40 DAS) and Pendimethalin 750 g/ha (PE) fb Imazethapyr 60 g/ha at 30 DAS remained at par and significantly reduced the density and dry weight of weeds. Hence, it resulted in significantly higher seed yield of cowpea. On the basis of results obtained, Pendimethalin 750 g/ha (PE) fb HW at 30 DAS found appropriate. Moreover, in view of the increasing wages and crisis of labour at critical periods, application of Pendimethalin 750 g/ha (PE) fb Imazethapyr 60 g/ha at 30 DAS can be proved equally effective and remunerative weed management option for cowpea.
