YIELD AND YIELD RELATED PERFORMANCE OF COWPEA (Vignia unguiculata L.) VARIETIES TESTED AT DIFFERENT FERTILIZER USE UNDER IRRIGATION, CENTRAL GONDAR ZONE, ETHIOPIA
Inadequate quantity and quality feeds is the major constraints to livestock production in majority of smallholder farmers in Ethiopia. This necessitates the need to follow economically viable forage production. A study was conducted to evaluate the yield and yield related performance of cowpea (Vignia unguiculata L.) varieties under irrigation in 2017 and 2018 years. The experiment was laid down in a split plot design with randomized complete block design (RCBD) arrangement in four replications. There were two main plots of which one was planted with fertilizer and the other one without fertilizer for comparison and the sub plot treatments were eight varieties of Cowpea (Vignia unguiculata) (ILRI 9333, ILRI 9334, ILRI 11114, ILRI 12688, ILRI 12713, Kenkety, Black eye bean and IT92KD258-9).
