Occurrence, Distribution And Evaluation Of Some Cowpea (Vigna Unguiculata (L.) Walp) Varieties For Their Reactions To Stem Rot In North - West Nigeria

📄 Project Abstract

Report of damage due to stem roton cowpea in some parts of Kaduna and Katsina States calls for urgent attention in finding possible ways of managing the disease.Knowing the status of the disease will help in employing necessary management strategy as it is a prerequisite to any pest management decision. This research was therefore conducted to determine the incidence, severity and causal organism(s) of cowpea stem rot in North - West Nigeria and evaluate some cowpea varieties for their reactions to the causal organism(s). The incidence and severity of cowpea stem rot in farmers fields were assessed in three Local Government Areas each in four cowpea producing states of North - West Nigeria, Kano, Kaduna, Katsina and Zamfara during 2013 and 2014 rainy seasons. The results showed that cowpea fields in Kaduna State had significantly higher incidence (29.09 %) and severity (21.14 %) than those in Kano, Katsina and Zamfara States for the two seasons. Katsina State had the lowest incidence (...
