Abstract

Sowing dates, maturity group and climate conditions associated with plant density can lead to different effects on soybean (Battisti et al., 2017). Light interception explains responses to plant density among different maturity groups and environments (Edwards et al., 2005). Decisions concerning sowing density need to take into account two main factors: the lowest possible sowing density to reduce seed costs, and the optimum possible interception of solar radiation. Crop models can help to evaluate the interaction between these factors, but studies about plant density are very scarce, especially for soybean. In order to better explore this knowledge gap, this study aims to evaluate the CSM-DSSAT-CROPGRO-Soybean regarding plant development and yield in response to plant density for two distinct soybean maturity groups (7.7 and 8.8) in low latitudes, Brazil.
