| Summary: | The use of cover crops in the no-tillage system can provide better conditions for the development of maize plants, with positive effects on grain yield. By using the growth analysis technique, this study aimed at characterizing the agronomic performance of maize on common bean, Brachiaria brizantha and millet straw. The experiment was carried out in a Brazilian Savannah soil, in Santo Antônio de Goiás, Goiás State, Brazil. The experimental design was randomized complete blocks, with three treatments (cover crops) and five replications. The common bean straw decomposition rate was higher than the B. Brizantha and millet ones. The highest values for the dry matter accumulation of leaves, stems, cobs and total, as well as leaf area index and maize grain yield, were observed when cultivated on common bean straw.
