Abstract
Cowpea also known as 'black eye beans' (Vigna ungiculata L.) is an important leguminous and hay crop in tropical and subtropical regions. In recent years root rot caused by Macrophomina phaseolina causes significant losses in cowpea. Hence, the present study was undertaken to assess the bio-potential of neem cake with Pseudomonas fluorescens on the management of cowpea root rot disease. In this study, P. fluorescens as seed and soil application (@ 10 gm/kg and 2.5 kg/ha) with neem oil cake as soil application @ 0.25 t/ha (T6) significantly reduced the root rot disease incidence with a maximum per cent disease reduction and increased the biometrics of cowpea plant under both pot and field trials. Keywords: Macrophomina phaseolina, cowpea, neem, in-vivo.
