| Resumo: |
Maize and soybean are the main crops used for crop yield on Brazilian Cerrado biome. The off-season maize intercropped with ruzigrass [Urochloa ruziziensis (R. Germ. & C.M. Evrard) Crins (Syn. Brachiaria ruziziensis Germ. & Evrard)] increases soil cover and yield for crops in succession. However, the benefits on maize yield depend on the distribution and radiation-use efficiency (RUE) and its conversion to biomass. This study aimed to evaluate maize and ruzigrass yield in different cultivation systems. The experiment was carried out at Embrapa Agropecuária Oeste, in Dourados, MS, Brazil. The experiment design was randomized blocks, with seven treatments constituted by the combination of spacing between maize rows, single and intercropped, with ruzigrass in distribution methods. Photosynthetically active radiation, chlorophyll, leaf temperature, morphological characteristics and maize mass yield were evaluated in maize at the flowering stage (R1). Maize and ruzigrass yield were evaluated during maize maturation. The reduced spacing in single maize has a higher yield and lower radiation incidence in the ear. Maize intercropped with ruzigrass sown by broadcasting showed higher leaf temperature, lower plant height and lower maize leaf area. Morphological and physiological characteristics and maize grain yield were more influenced by planting methods than the presence of ruzigrass. The highest yield of dry matter and maize grain occurred in reduced spacing in maize, either alone or intercropped with ruzigrass.
