Ensuring global food security is one of the great challenges of mankind for decades. The population increase of the planet by about 2 billion people, a rising trend of the middle class and projections of climate change has been considered as one of the great future challenges for international food security policies. In this sense, research aimed at intensifying agriculture can contribute to the issue of food security. The soybean crop generates more than 60% of all the food protein of plant origin produced worldwide. Brazil is the largest exporter and the largest producer of soybeans (Glycine max) in the world. However, the productive potential of the crop is still unknown in the Brazilian production system. Potential soy production protocols and simulations with process-based models, properly calibrated, already developed in the most famous soybean countries, such as USA and Argentina. Recently, published studies indicate that the productive potential of soybean in a temperate environment is greater than initially spreading, creating doubts and interesting scientific hypotheses about a potential crop production in a tropical environment. There is no literature yet on a potential productivity of soybeans in the tropics, and a principle is understood that even the results of competition trials are still below the potential of production of the crop, even reaching productivities well above national averages. The present study aims to quantify the productive potential of soybeans in Brazil through robust potential production experiments, as well as to evaluate crop efficiency on a national scale based on the Global Yield Gap Atlas (GYGA) project approach, internationally recognized, thus achieving comparable results with other producer countries. No end of this study is expected to identify and describe comparatively the factors determining the productive potential of soybeans under tropical conditions and to generate an atlas of soybean production efficiency for Brazil following international protocols for this type of procedure.
