Conteúdo: | The objective of the study was to evaluate the productive efficiency of yerba mate regarding growth parameters, subjected to different conditions of cultivation, luminosity, and fertilization. The arboreal component entered to produce shade, corresponding to 60%, 45% and 30% of the light intensity. The luminosity levels were combined with different forms of fertilization: conventional fertilization (CF), controlled- release fertilization (CRF), and unfertilized (UF). The CF and CRF resulted in increase leaf area at 45% and 30% levels of luminosity. The dry weight of the leaves was 9.40% higher using CF, when compared to the unfertilized. Canopy diameter was less sensitive to variations in fertilization but significant in shading, in which the competition limit was described when submitted to 45% luminosity. The height of the yerba mate was homogeneous, and leaf biomass productivity displayed greater efficiency in 60% luminosity, without the use of fertilizer. CF promoted an increment of 8.67% in biomass productivity when under 45% apparent luminosity.
