maize. The treatments combinations are listed below in Table 2. The experimental plot size was
be 5 m x 4 m (20 m 2 ).The experiment was laid out in factorial randomized complete block design
(RCBD) with three replications.

Maize was planted at a spacing of 80 x 25 cm while cowpea varieties, which had been planted
three weeks later after maize at 1:2 maize-cowpea spatial arrangement, was planted with intra-row
spacing of 20 cm, 30 cm and 40 cm based on the treatments which represented 100%, 75% and
50% of the recommended cowpea planting density, respectively. Moreover, the three varieties of
cowpea
were planted at a spacing of 40 x 20 cm.
3.4. Experimental Procedure and Field Management
The experimental land was mechanically prepared by ploughing and harrowing. The plots were
laid out and treatments were randomly assigned onto the plots.
