Precision Agriculture (PA) allows the use of different tools in obtaining information, and they optimize decision making by producers having a positive impact on the final recipe. The objective was to verify the behavior of the production variables (PROD), canopy (CV) and stem diameter (SD) variety Maxi Gala with the use of the cokriging technique. The experiment was conducted in an area of ??0.90 hectares of commercial production of the variety Maxi Gala at Fazenda São Paulino RASIP Company in Vacaria - RS presenting as geographical coordinates 28º31’17” south latitude and 50º49’17” west longitude during 2010/11 and 2011/12 crops. It was collected 75 samples for each variable in a loop of 12m between line and 10 m on the line. The variables evaluated were yield per plant, canopy volume and diameter. Descriptive statistical analysis and spatial analysis through the semivariogram were made. By having the adjusted models, it was held the interpolation by the kriging method. After it was performed a simple correlation of the parameters, prepared the crossed semivariogram for the interpolation by the cokriging technique. The PROD versus SD parameters showed an average correlation in the Maxi Gala cultivar in 2011 harvest. In 2011 and 2012 harvests the CV versus SD parameters also showed an average correlation. The cokriging technique can be a PA tool to be used by apple culture in gathering information. It was found that there was response and reduction in collecting samples of the most difficult variables, in the 2011 harvest 15 samples of PROD were reduced and in the 2012 harvest 20 samples of the CV were reduced.
