Nutrient injection: an efficient technique to increase plantain (Musa AAB) crop yield
Introduction. There are alternative fertilization methods such as fertilizer injection to the pseudostem that present greater efficiency than traditional edaphic fertilization. Objective. To evaluate the effect of soil fertilization and nutrient injection on morphological variables and bunch weight of the plantain in soils of variable fertility. Materials and methods. Two experiments were established in the municipalities of Viota and Chaguaní, Cundinamarca, Colombia, in 2018. A completely randomized design in bifactorial arrangement was used. The two experiments were: Experiment A: two locations and two types of fertilization (traditional and soil chemistry) and Experiment B: two locations and four nutritive solutions (one based on amino acids and another one with nutrients, both in two proportions) and a control. The response variables were: bunch weight, days from flowering to harvest, diameter, and external length of the central finger. Results. Organic edaphic fertilization in Chaguaní soil had no effect on bunch weight compared to chemical sources. In Viotá, soil chemistry fertilization increased bunch weight compared to the use of traditional soil fertilization. This differential response is explained by the fact that in Chaguaní the soil had a higher exchange capacity, nutrient content, and organic carbon. The plants planted in Chaguaní produced heavier bunches (21.6 kg) compared to Viotá (19.0 kg), but in the last one the fingers of the bunch were shorter. The nutrient injection in both locations increased the plantain crop yield compared to the control without injection. Conclusions. A low dose of fertilizer in the high fertility soil had a similar effect on plantain production recorded in the low fertility soil that received a high dose of fertilizer. The injection of nutritive solutions should be validated as a complementary alternative to the traditional soil fertilization.

Existen métodos alternativos de fertilización como la inyección de fertilizantes al seudotallo que presenta mayor eficiencia que la fertilización edáfica tradicional. Objetivo. Evaluar el efecto de la fertilización edáfica e inyección de nutrientes sobre variables morfológicas y peso del racimo de plátano en suelos de fertilidad variable. Materiales y métodos. Se establecieron dos experimentos en los municipios de Viotá y Chaguaní, Cundinamarca, Colombia, en 2018. Se usó un diseño completamente aleatorizado en arreglo bifactorial. Los dos experimentos fueron: Experimento A: dos localidades y dos tipos de fertilización (tradicional y química edáfica) y Experimento B: dos localidades y cuatro soluciones nutritivas (una a base de aminoácidos y otra con nutrientes, ambas en dos proporciones) más un testigo. Las variables de respuesta fueron: peso de racimo, días de floración a cosecha, diámetro y longitud externa del dedo central. Resultados. La fertilización edáfica orgánica en el suelo de Chaguaní no tuvo efecto sobre el peso del racimo en comparación con las fuentes químicas. En Viotá, la fertilización edáfica química incrementó el peso del racimo en comparación con la fertilización tradicional. Esta respuesta diferencial se explica porque en Chaguaní el suelo presentó mayor capacidad de intercambio, contenido de nutrientes y carbono orgánico. Las plantas sembradas en Chaguaní produjeron racimos de mayor peso (21,6 kg) en comparación con Viotá (19,0 kg), pero los dedos del racimo fueron más cortos en esta localidad. La inyección de nutrientes en ambas localidades incrementó el rendimiento del cultivo del plátano en comparación con el testigo sin inyección. Conclusiones. Una dosis baja de fertilizante en el suelo de alta fertilidad generó un efecto similar en la producción de plátano registrada en el suelo de baja fertilidad que recibió una dosis alta de fertilizante. La inyección de soluciones nutritivas se debe validar como alternativa complementaria a la fertilización edáfica tradicional.
