The yield variability of sweet orange groves located in Luiz Antonio country, Sao Paulo State, Brazil, was evaluated using geostatistics. Through the kriging maps, areas with higher and lower yields in the groves were determinated. A great variability of yield and fruit size on irrigated and non-irrigated groves was verified. Thus, the geostatistic showed to be an extremely useful tool to enhance Precision Agriculture Programs.
