Abstract. The objective of this study was to evaluate the long-term effects of piling secondary forest residue (after 3 decades) on soil chemical properties, growth, and nutrition of Pinus taeda and weeds at three locations. After secondary forest removal and residue piling, areas were cultivated with P. taeda (22 years), followed by eucalyptus (7 years), and returned to P. taeda. At 2 years of age, tree height and needle-nutrient levels of ongoing P. taeda from areas influenced by residue piling and areas outside the piling zone were evaluated. Biomass and nutrient levels of herbaceous and shrub weeds, NDVI indices (via a drone), and soil chemistry were also evaluated. Residue-piled areas displayed a decrease in soil pH and an increase in available soil P and K. Although herbaceous and shrub-weed biomass increased 2.5 to 10 times in residue-piling areas, this did not compromise pine growth. While residue piling had little impact on the nutritional status of pine and weeds, NDVI values indicated greater plant growth in piling areas. In general, the long-term effect of residue piling was an important factor associated with the large variation in tree growth and weed incidence after 3 decades. |

ABSTRACT - The objective of this work was to evaluate the bromatological composition, bioactive compounds, antioxidant activities, and color of the leaves of olive cultivars Arbosana, Arbequina, Frantoio, Manzanilla, and Koroneiki in northwestern Paraná, Brazil. Leaves of each cultivar were collected for the experiment, which was carried out in a completely randomized design. The dry matter (DM) of olive leaves contains mostly carbohydrates (56.15 to 59.42 g 100 g-¹ DM) and fibers (17.37 to 19.73 g 100 g-¹ DM) in its bromatological composition. The total polyphenol content ranges from 13.27 to 22.81 mg GAE g-¹, with cultivar Manzanilla standing out, and the flavonoid content from 6.50 to 7.65 mg QE g-¹. Manzanilla shows the highest antioxidant activity of 93.56 and 78.15% in the DPPH and ABTS assays, respectively. When compared with the other cultivars, Manzanilla and Koroneiki have leaves with a higher green intensity and total chlorophyll content of 0.958 and 0.833 mg 100 mL-¹, respectively. In the ABTS assay, there is a correlation both between total polyphenol content and antioxidant activity and between chlorophyll content and antioxidant activity. Olive leaves have characteristics that allow their application as an additive or ingredient for the development of food products with satisfactory antioxidant activity. RESUMO - O objetivo deste trabalho foi avaliar a composição bromatológica, os compostos bioativos, as atividades antioxidantes e a cor das folhas das cultivares de oliveira Arbosana, Arbequina, Frantoio, Manzanilla e Koroneiki no noroeste do Paraná, Brasil. Folhas de cada cultivar foram coletadas para o experimento, realizado em delineamento inteiramente casualizado. A matéria seca (MS) das folhas de oliveiras contém majoritariamente carboidratos (56,15 a 59,42 g 100 g-¹ de MS) e fibras (17,37 a 19,73 g 100 g-¹ de MS) em sua composição bromatológica. O teor de polifenóis totais varia de 13,27 a 22,81 mg EAG g-¹, com destaque para a cultivar Manzanilla, e o conteúdo de flavonoides de 6,50 a 7,65 mg EQ g-¹. Manzanilla apresenta a maior atividade antioxidante de 93,56 e 78,15% nos ensaios DPPH e ABTS, respectivamente. Em comparação às demais cultivares, Manzanilla e Koroneiki apresentam folhas com maior intensidade de verde e teor de clorofila total de 0,958 e 0,833 mg 100 mL-¹, respectivamente. No ensaio ABTS, há correlação tanto entre o teor de polifenóis totais e a atividade antioxidante quanto entre o teor de clorofila e a atividade antioxidante. As folhas de oliveira apresentam características que permitem sua aplicação como aditivo ou ingrediente para o desenvolvimento de produtos alimentícios com atividade antioxidante satisfatória.
