Diagnostico nutricional del cultivo de la lima ácida Tahití [Citrus latifolia (Yu Tanaka) Tanaka] en el departamento del Tolima (Colombia)

In Colombia, the diversity of agroecosystems gives the coffee characteristic flavors and aromas. In the coffee crops of the Union Nariño municipality, located at 1º 36’ 06” ‘North latitude and 77º 00’ 15’’ West longitude, the coffee activity takes place in heterogeneous farms in terms of extension, distances of sowing, applied technology, organization, family structure and fundamentally in the use and management of shade; which is why it is important to typify them by integrating the social, economic and environmental dimension and establish the differences between them, know their dynamics and determine the potential and limitations to contribute to the planning, research and organization of the coffee sector. A semi-structured survey was applied to 104 coffee producers located between 1400 and 1800 meters above sea level. This information was complemented with information from institutions linked to the coffee sector. A multivariate analysis from a cluster analysis (Ward method and principal components) was applied to the variables with high correlation. Four typologies of production systems were established: coffee with shade of woody (S1), coffee semi-shade (S2), coffee-banana (S3) and the coffee without shade (S4). Within each typology, different dynamics were found in crop management practices, leading to differences in production, quality and economic yields. El departamento del Tolima es el principal productor de lima ácida [Citrus latifolia (Yu Tanaka) Tanaka] en Colombia. Se calcula que entre el Tolima y el Huila existen cerca de dos mil hectáreas cultivadas. El sistema productivo presenta diferencias importantes entre los productores en el manejo tecnológico con relación al riego y a la nutrición mineral, ambos relacionados significativamente con los rendimientos y calidad de la fruta. El objetivo de este estudio fue comparar la precisión, versatilidad y confiabilidad de tres métodos de interpretación de los análisis nutrimentales en el cultivo de lima Tahití. Para ello se realizaron análisis de suelo y foliares a dos plantas adultas en 20 fincas de siete municipios del departamento del Tolima cuyos resultados se interpretaron bajo el Sistema Integrado de Diagnóstico y Recomendación (DRIS), el método de Desviación del óptimo Porcentual (DOP) y el método convencional o de Rangos de Suficiencia (RS).La información se comparó con rangos de suficiencia y se calculó la desviación del óptimo porcentual (DOP). La técnica DOP permitió diagnosticar con m
