Abstract

The present study evaluated the effect of organic amendments (poultry manure and manure), applied individually and in combination with conventional fertilization, on the agronomic performance and profitability of cabbage (Brassica oleracea var. capitata) to optimize its nutritional management. Four treatments were compared: T1 (poultry manure + conventional fertilization), T2 (only poultry manure, 173.38 kg/ha), T3 (cuyaza + conventional fertilization) and T4 (only cuyaza, 173.39 kg/ha). The experiment was conducted under a Randomized Complete Block Design with five replications per treatment. The variables evaluated were plant height, cabbage diameter and weight, and yield, analyzed by ANOVA and Tukey's test (α = 0.05). The results revealed significant differences only in cabbage diameter, where the combined treatments (T1: 10.92 cm and T3: 10.98 cm) were statistically superior to the exclusively organic treatments (T2 and T4). The economic analysis indicated that none of the treatments reached acceptable profitability levels, with T1 being the best economic performer (B/C = 0.03), although insufficient to be considered viable. These results highlight the need to optimize doses and explore more cost-effective nutritional strategies to improve the sustainability of the production system.
