3.3. Treatment and Experimental Design
Three cowpea varieties and three cow pea population densities were intercropped with a maize
variety Melkasa 4. The cowpea varieties were Kenketi, Black eye bean and Bole. Cowpea
population densities were 100% (recommended seed rate), 75% and 50% in additive series for
