| ABSTRACT The objective of this study was to evaluate the levels of macronutrients in cladodes and yield of cactus pear, cv. ‘Gigante’, cultivated with different cattle manure doses and plant spacings. The experimental design was randomized blocks in 4 x 3 factorial, with three replicates. The treatments consisted of the combination of four doses of cattle manure (0, 30, 60 and 90 Mg ha-1 year-1) with three spacings (1.00 x 0.50, 2.00 x 0.25 and 3.00 x 1.00 x 0.25 m). The contents of macronutrients and dry matter production of cladodes were assessed 600 days after planting. The plant spacings influenced the contents of nitrogen, potassium, calcium and sulfur in the cladodes of ‘Gigante’ cactus pear and there was interaction between spacing and manure dose... |

| ABSTRACT This study aimed to evaluate the extraction/exportation of macronutrients by cladodes of ‘Gigante’ cactos pear, grown under diferente spacings and doses of cattle manure applied to the soil 600 days after planting. Twelve treatments were used, three spacing (1.00 x 0.50; 2.00 x 0.25 and 3.00 x 1.00 x 0.25 m) and four doses of cattle manure (0, 30, 60 and 90 Mg ha-1 year-1), arranged in a 3 x 4 factorial scheme in randomized blocks, with three replicates. The extraction/exportation of N, P, K, S, Ca and Mg was determined, whose respective values for maximum dry matter production (21.8 Mg ha-1), with a cattle manure dose of 71.8 Mg ha-1 year-1 were: 287.9, 46.2, 924.2, 40.7, 609.7 and 249.1 kg ha-1, 600 days after planting. The amounts... |
