Climatic indicators and soybean yield in Rio Grande do Sul
Abstract The main of this work was to identify teleconnection patterns that influence soybean yield variability in Rio Grande do Sul in order to find potential predictors of agricultural yield in the State. Soybean yield data from 87 municipalities provided by the Brazilian Institute of Geography an...

These indices also showed a high correlation with the precipitation between December and March for each homogeneous group evidencing the importance of their monitoring for the planning of the soybean farming in Rio Grande do Sul.
