Summary: ABSTRACT. The objective of this work was to study the variability of maximum temperature and chlorophyll A in an agroforestry system using the geostatistics technique. This study was carried out in an area of 0.8 hectares with an integrated crop and forestry system managed by Embrapa Agrossilvipastoral in Sinop, MT - Brazil. Results from semivariograms models have shown that maximum temperature had no spatial dependence detected, problaby because of the small size area where this variable seemed constant. Conversely, Chlorophyll A has shown spatial dependence after semivariogram adjustments. It was observed that the highest values of chlorophyll A were located where there were no trees and the lowest maximum temperatures close to the pequi trees, likely due the solar energy availability.
