dc.descriptionCrop densification can influence the nutritional quality of cactus pear. However, studies considering harvest timing and cultivation density in high-altitude regions are essential for optimizing management and supporting sustainable livestock farming. Thus, the aim of this study was to evaluate the chemical, mineral composition and mineral accumulation of cactus pear under different planting densities. A randomized block design was used, with four planting densities (30,000; 45,000; 60,000 and 75,000 plants.ha 1) and four replications, evaluated at 120, 240 and 360 days after planting (DAP). Field sample collections occurred every 120 days. The samples were processed for further evaluation of their chemical and mineral composition, as well as mineral accumulation in relation to degree days. Increasing planting densities reduced dry matter, crude protein, neutral and acid detergent fiber contents, while increasing hemicellulose, glucose, sucrose, and starch (p < 0.05). A quadratic effect was observed for ether extract and pectin contents with increasing planting densities (p < 0.05). At 360 DAP, the highest levels of dry matter, organic matter, carbon, ether extract, neutral and acid detergent fiber, hemicellulose, cellulose, lignin, total and non-fibrous carbohydrates, sucrose, starch, and pectin were observed (p < 0.05). The highest mineral matter, sulfur, manganese, and zinc contents occurred at 120 and 240 DAP (p < 0.05). Crude protein and iron levels peaked at 120 DAP, while glucose, potassium, calcium, magnesium, and sodium were highest at 240 DAP (p < 0.05). The highest phosphorus levels were found at 120 and 360 DAP (p < 0.05). Mineral accumulation varied according to planting density and accumulated degree days. Phos- phorus, calcium, and magnesium showed specific peaks, while potassium and zinc followed rainfall patterns. Sodium increased progressively. Higher planting densities (75,000 plants.ha⁻¹) increased carbohydrate reserves without altering mineral composition. The findings contribute to the knowledge of cactus pear agronomic management and reinforce the importance of strategies that promote sustainable production, aiming to ensure greater efficiency in the use of cultivable areas and forage production in semi-arid regions.
