Abstract

Purpose: The purpose of this study was to determine the effect of spacing on grain yield and above ground biomass of cowpea.

Methodology: A randomized complete block design was used. Field experiments were conducted. The study was conducted at Agriculture demonstration farm (Dakabaricha) and Yayo's farm(Nagayo) and a private farm Demo farm. There were 18 treatment combinations consisting of three water harvesting techniques and two intra-row spacing.

Results:Tied ridges with cross bars at 2.5m interval with the spacing of 60 x 20cm (W3 /S1) and open ridges with a spacing of 60 x 20cm (W3/S1) recorded the highest grain yield of 1408 kg/ha and 1296 kg/ha respectively.

Unique  Contribution to Theory, Practice and Policy:An assessment of adaptation of more cowpea genotypes at different environments across years is recommended. The investigation provided sufficiently evidence to continue with further studies.
