RESUMO  -   A variabilidade e os baixos rendimentos da melancia no Nordeste brasileiro estão atrelados à falta de pesquisas sobre o manejo de adubação da cultura. Objetivou-se com esse trabalho avaliar a produção de melancia em solo submetido a doses de esterco bovino e potássio. Os tratamentos foram distribuídos em blocos ao acaso, com três repetições e 21 plantas por parcela em arranjo fatorial 3 × 5 + 1, referente à três doses de esterco bovino (0,0; 1,10 e 2,52 kg cova-1), cinco doses de potássio (0,0; 7,5; 15; 22,5 e 30 kg ha-1), e um tratamento adicional (sem adubação orgânica e mineral). Exceto o tratamento adicional, os demais tratamentos receberam nitrogênio, na forma de ureia (120 kg ha-1 de N). Foram avaliados: o número de frutos por planta, massa média dos frutos, produtividade e tamanho dos frutos (diâmetro longitudinal dos frutos-DLF e diâmetro equatorial dos frutos-DEF). As doses de K2O fornecidas não foram suficientes para elevar a massa média dos frutos de melancia a valores satisfatórios. A dose 1,10 kg cova-1 de esterco bovino foi a que promoveu maiores valores de produtividade. O incremento na dose de esterco bovino reduziu a necessidade de fertilizante potássico para elevar a produtividade das plantas de melancia.

ABSTRACT  -   The variability and low Watermelon yields in northeastern Brazil are linked to the lack of research on the fertilization management of culture. This experiment aimed to evaluate the watermelon production at soil under the levels cattle manure and potassium. The treatments were distributed in randomized block design with three replications and 21 plants per plot in factorial scheme 3 × 5 + 1, referring to three cattle manure levels (0.0 1.10 and 2.52 kg hole-1), five K2O levels (0.0; 7.5; 15; 22.5 and 30 kg ha-1), and one additional treatment (without organic and mineral fertilizers). Except additional treatment, the other treatments received nitrogen, in the form of urea (120 kg ha-1 N). Were evaluated: number of fruits per plant, average fruit weight, productivity and fruit size (longitudinal diameter fruit-LDF and equatorial diameter fruit-EDF). The K2O levels supplied were not sufficient to raise the average mass of watermelon fruits to satisfactory values. The 1.10 kg dose of bovine manure was the one that promoted higher values of productivity. The increase in the dose of manure reduced the need for potassic fertilizer to increase the productivity of watermelon plants.
