Resumo: | ABSTRACT The present study evaluated the accumulation and export of nutrients in cactus pear (Opuntia ficus-indica) cv. Gigante, fertilized with combinations of nitrogen (10, 70, 100, 130, and 190 kg ha−1 year−1 N) and phosphorus (10, 70, 100, 130, and 190 kg ha−1 year−1 P2O5) under annual and biennial harvests, in Quixadá and Tejuçuoca, using a split-plot randomized block design with four replications. In Quixadá, under annual and biennial harvests, the following orders of accumulation of macronutrients (in kg ha−1 year−1) were found, respectively: K (98.8) &gt; Ca (87.2) &gt; N (46.7) &gt; Mg (26.8) &gt; S (18.4) &gt; P (2.04) and Ca (33.5) &gt; K (31.1) &gt; S (18.6) &gt; N (12.9) &gt; Mg (10.5) &gt; P (0.81). In Tejuçuoca, under annual and biennial harvests, the orders of accumulation of macronutrients were, respectively: K (146.5) &gt; Ca (204.6) &gt; N (128.1) &gt; Mg (75.8) &gt; S (50.3) &gt; P (3.7) and K (397.2) &gt; N (191.3) &gt; S (241.2) &gt; Ca (167.8) &gt; Mg (131.0) &gt; P (14.1). The maintenance/production fertilization in cactus pear should be planned according to productive potential, fertilization and harvest managements, and cultivation region, based on nutritional requirement and considering the nutrient recovery efficiency.
