A field experiment was conducted at Alduba, Southern Ethiopia to determine the effect of moisture conservation practices and varieties on yield and yield components of cowpea (Vigna unguiculata L.) under rain fed condition in 2013. The experiment was conducted with two levels of moisture conservation practices (farmers practice and tied ridge), eight cowpea varieties (Black-eye bean, Bole, Maze-1, Asrat, Bekur, Assebot, IT-99k-1122 and White-wonder-trail).
