Agronomic and economic responses of the potato (Solanum tuberosum subsp. andigena) to differential fertilization in four environments in Nariño, Colombia

| description | Due to the importance of potato cultivation in Nariño, Colombia and the high participation of fertilizer in production costs (25%), as well as the great variability of soils in the region, we evaluated three fertilizer levels for six cultivars of Solanum tuberosum subsp. andigena in four homogeneous production environments. We recorded physiology and yield of the potatoes in experimental plots in a randomized complete block design with three replications in each environment. Analysis of variance, comparison of means for yield components, and discriminant analysis of principal components were performed for all variables. For the economic analysis we used the partial budget net benefit methodology. The environments generated differential responses in the cultivars. Between fertilization levels there were significant differences; however, there was no interaction between levels and environments. The cultivars ‘ICA Única’, ‘Pastusa Suprema’, ‘Parda Bilingüe’, and ‘Roja Huila’, showed the highest yields with the application of 262, 600, and 538 kg ha-1 of N, P2O5, and K2O (level L3). ‘Diacol Capiro’ and ‘Superior’ did not show yield differences between levels. Economically, the alternative that would generate the highest return on investment was fertilization with level L2 (N 180, P2O5 400, K2O 358 kg ha-1) in ‘Diacol Capiro’, ‘Superior’, and ‘ICA Única’ cultivars. For ‘Roja Huila’ and ‘Parda Bilingüe’ the highest return was level L1 (N 150, P2O5 200, K2O 100 kg ha-1). In the case of ‘Pastusa Suprema’ the marginal rate of return was 18.5% with the L2 fertilization level. |

Debido a la importancia del cultivo de papa en Nariño, Colombia, la alta participación de fertilizantes en los costos de producción (25%) y la gran variabilidad de suelos en la región, se evaluaron agronómica y económicamente tres niveles de fertilización para seis cultivares de Solanum tuberosum subsp. andigena en cuatro ambientes homogéneos de producción. Variables fisiológicas y de rendimiento fueron registradas en parcelas experimentales con un diseño de bloques completamente al azar con tres repeticiones en cada ambiente. Se realizaron análisis de varianza, comparación de medias para componentes de rendimiento y análisis discriminante de componentes principales con todas las variables. En el análisis económico se usó la metodología de presupuesto parcial de beneficio neto. Los ambientes generaron respuestas diferenciales en los cultivares. Entre niveles de fertilización hubo diferencias significativas, sin embargo, no hubo interacción entre niveles y ambientes. Los cultivares 'ICA Única', 'Pastusa Suprema', 'Parda Bilingüe' y 'Roja Huila' presentaron los mayores rendimientos con la aplicación de 262, 600 y 538 kg ha-1 de N, P2O5 y K2O (nivel L3). 'Diacol Capiro' y 'Superior' no presentaron diferencias de rendimiento entre niveles. Económicamente, la alternativa que generaría mayor retorno por la inversión fue la fertilización con el nivel L2 (N 180, P2O5 400, K2O 358 kg ha-1) en los cultivares 'Diacol Capiro', 'Superior' e 'ICA Única', mientras que para 'Roja Huila' y 'Parda Bilingüe' fue el nivel L1 (N 150, P2O5 200, K2O 100 kg ha-1). En el caso de Pastusa Suprema, la tasa de retorno marginal fue de 18,5% con el nivel L2 de fertilización.
