Soil water dynamics and yield in maize and Brachiaria ruziziensis intercropping [PDF]

Pesquisa Agropecuária Tropical, 2020
ABSTRACT In intercropping systems, a high plant density can delay the biomass accumulation and affect the water availability to plants. This study aimed to evaluate the soil water dynamics and the crop yield performance in maize and Brachiaria ruziziensis intercropping under different sowing densities of the forage grass.

Phenotypic characteristics for discrimination between advanced genotypes of Brachiaria ruziziensis

Genetics and Molecular Research, 2016
The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications.
