| description | The objective of this study was to evaluate the effects of nitrogen, phosphorus and potassium doses on tree tomato (Solanum betaceum Cav.) growth in the vegetative phase. This research was conducted under greenhouse conditions at the National University of Colombia, Bogotá. A randomized block design was employed to evaluate eight treatments with three replicates as follows: i) CC: commercial control, ii) CS: control without fertilization, iii) Low N: 10% of the recommended dose (DR); iv) Low P: 10% DR; v) Low K: 10% DR, vi) High N: 200% DR; vii) High P: 200% DR, and viii) High K: 200% DR. The fertilizer plan was adjusted according to the soil analysis and doses reported for the species. To determine plant growth, growth rate indexes were used based on the functional logistic model. The treatment without fertilization CS and High P reduced the leaf area, number of leaves, stem length, and dry mass of leaves of the tree tomatoes by about 50%, unlike the commercial control (CC). The Low K treatment increased the same variables by 70%, as well as the total dry mass. For growth rates, the Low K treatment resulted in the highest leaf area index and relative growth rate, and the High K treatment presented the highest crop growth rate. |

El presente trabajo tuvo como objetivo evaluar el efecto de dosis de nitrógeno, fósforo y potasio sobre el crecimiento del tomate de árbol en etapa vegetativa. Se realizó bajo condiciones de invernadero en la Universidad Nacional de Colombia (sede Bogotá) y se empleó un diseño de bloques aleatorizado, donde se evaluaron ocho tratamientos, con tres réplicas, así: CC, control comercial o dosis recomendada; CS, control suelo sin ninguna fertilización; Bajo N, 10% de la dosis recomendada (DR); Bajo P, 10% DR; Bajo K, 10% DR; Alto N, 200% DR; Alto P, 200% DR y Alto K, 200% DR. El plan de fertilización se ajustó según análisis físico-químico del suelo y dosis reportadas para el cultivo. Para determinar el crecimiento de las plantas se emplearon algunos parámetros e índices de crecimiento utilizando un modelo logístico de enfoque funcional. Los resultados evidenciaron que el tratamiento CS y Alto P redujeron cerca de un 50% el área foliar, número de hojas, longitud total de la planta y masa seca de las hojas a diferencia del control comercial (CC). El tratamiento Bajo K aumentó en un 70% las variables mencionadas, así como la masa seca total. Para las tasas de crecimiento el tratamiento Bajo K presentó el mayor índice de área foliar y tasa relativa de crecimiento, y el tratamiento Alto K presentó la mayor tasa de crecimiento del cultivo.
