Abstract

The aim was to evaluate the agronomic performance of maize intercropped with Urochloa ruziziensis and Crotalaria spectabilis under different interrow spacings. The treatments were constituted by two maize interrow spacings (0.50 m and 0.90 m) and four maize cropping modalities (sole maize, maize + Urochloa ruziziensis, maize + Crotalaria spectabilis, and maize + U. ruziziensis + C. spectabilis). The reduced interrow spacing increases plant height (4%) and main ear insertion (7%) compared to 0.90 m interrow spacing, and consequently results in a smaller stem diameter (19%) in maize plants. Overall, maize yield was 32% higher at 0.50 m interrow spacing compared to 0.90 m. The maize + U. ruziziensis + C. spectabilis intercropping combined with 0.50 m interrow spacing showed a yield 5% lower than sole maize, mainly caused by the reduction of 100-grain weight.
