Nutritional balance and recovery rate of macronutrients by ‘Gigante’ cactus pear under different fertilizations

ABSTRACT The objective of this study was to evaluate nutrient export, nutritional balance and macronutrient recovery rate in ‘Gigante cactus pear under different fertilization doses, spacings configurations during three production cycles. 72 treatments were arranged a randomized block design with repetitions, two the plots (triple quadruple row), subplots (3.00 x 1.00 0.25 m; 3.00 0.16 m 0.125 m); 12 types sub-subplots (with organic, organomineral mineral sources). Exports nutrients are higher fertilizers supplies, regardless source. order export K > Ca N Mg S P for fertilization, organic 30 ha-1 year-1 60 plus NPK PK, it changed 90 K. after cycles positive N, S, negative all fertilizations, 600 kg K2O 30, K2O. highest rates lowest occur fertilization.
