Off‐season crops as a strategy for renovating degraded pastures and improving maize yield in a low‐altitude tropical region

Agronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Brazil can expand cultivated areas without deforestation by restoring degraded pastures and optimizing grain production through off‐season crops. This study evaluated eight off‐season treatments, including fallow, monocrops, and intercropping combinations, and their effects on maize (Zea mays L.) intercropped with guinea grass (Megathyrsus ...
