How does the condition of the pasture in late winter influence the plant and animal responses in the subsequent seasons?

Bioscience Journal, 2022
This study aimed to test the hypotheses: (i) the deferred pasture with lower height in late winter has greater herbage accumulation rate (HAR) and better structure, which facilitates the animal selective grazing during the subsequent spring and summer ...

Intercropping Urochloa brizantha and sorghum inoculated with Azospirillum brasilense for silage

REVISTA CIÊNCIA AGRONÔMICA, 2018
ABSTRACT Livestock performance in the Brazilian Cerrado has been limited by the low availability of good quality fodder, especially during periods of low rainfall. The aim of this study was to evaluate growth and dry matter production in two cultivars of sorghum, inoculated or not with diazotrophic bacteria, and as a monocrop or intercropped with ...
