Effectiveness of cowpea (Vigna unguiculata L.) living mulch on weed suppression and yield of maize (Zea mays L.)

Weed control plays a vital role in achieving higher maize yield. We tested the hypothesis that interseeding cowpea as living mulch with maize will reduce biomass and diversity of weeds, and improve soil physical properties and maize yield. In 2017/2018 cropping seasons, a 2 × 4 factorial experiment...
