The researchers studied how controlling soil moisture with irrigation and mulching affects the yield of maize and cucumber grown together during the dry season in Nigeria. They tested different levels of irrigation and mulching, along with fertilizer, for eleven weeks. The plants' growth was similar, but the yield of maize and cucumber varied significantly. Cucumber yield was highest with mulching alone. The study shows that combining irrigation and mulching can help farmers get the best yields for maize and cucumber intercrop during the dry season.
