Integration systems allow production rational use of natural resources. Studies of the leaf area is an important tool in the analysis of plant growth and development. Thus, the objective of this research was to evaluate the leaf area of Eucalyptus urograndis hybrid (H13) in the crop-livestock-forest integration system (iCLF) considering the planting configuration, the face exposure and stratification of canopy and compare methods of leaf area measurement. Data collection was carried out at EMBRAPA agrosylvopastoral in the integration systems on management of dairy cattle and beef cattle . The measurement of leaf area was held by ÁreaMed and ImageJ software and leaf area integrator. In iCLF-dairy, both in the spatial arrangement as the exposure face influenced jointly, so that the triple axis spatial arrangement presented in greater leaf area. In iCLF-beef, the leaf area in triple planting configuration, the faces exposure did not differ significantly. That system showed stratification decreasing the top to the center of the canopy. The methods did not differ in leaf area measurement with the standard method. The ImageJ software is presented as an alternative method in leaf area measurement in relation to the integrator method. The spatial arrangement, the face of exposure and the collection season relate to the leaf development in the integration system with dairy cattle. In the stratification, the highest values of leaf area are present in the center of the canopy.
