Spatial distribution of physiological quality of Arábica coffee seeds to cultivate Catuai

Brazil stands as the largest coffee producer in the world. However one of the factors capable of undermining the potential of this species is the poor quality of seeds. One tool that is being proposed for use in agriculture is the Geostatistics analysis to verify the existence and quantify the degre...
