Yield of maize and cowpea under variable seasonal rainfall, land form, tillage and weed management on the vertisols of Ghana

The effects of variable seasonal rainfa11, predicted supplementary irrigation, cultural practices (landforms, tillage and weed management) and their interactions on the yields ef maize and cowpea grown on the Vertisols in the Accra plains are examined.Based on long-term (27-years) seasonal daily rainfa11 data and the test crops maize and cowpea, transformation factors of 1.61 and 1.24 are obtained for the major and minor seasons, respectively.These are subsequently employed to obtain potential yields ofthe creps under supplementary irrigation. The potential yields of maize and cewpea given supplementary irrigation arc significantly (p
