A two-year study was conducted in a smallholder farming area in northeast Zimbabwe to determine the rotational effects ofpigeonpea (Cajanus cajan L. Millsp.) of different maturity genotypes on maize (Zea mays L.) yields. Researcher and farmer-managed on-farm rotation experiments were established on ten sites in farmers’ fields, with a long history of maize monocropping. A maize crop receiving different rates of mineral N fertilizer followed long, medium and short duration pigeonpea genotypes plus control maize. Relationships between N management factors and nutrient uptake by maize under the three pigeonpea genotypes were examined in light of the current soil fertility management practices by the farmers.
