Importancia de los micronutrientes edáficos: zinc, manganeso y boro, para una buena producción en el cultivo perenne de guanábana (Anona muricata).

The field of exotic fruits is currently growing due to its great potential, however, it requires care to ensure quality production. Soursop is one of the best known tropical fruits in the country, is widely consumed for its medicinal benefits, high nutritional value and the amount of food obtained from its use. The main production sectors are located in the Peninsula of Santa Elena and Guayas, however, there are several areas of the country where it grows endemically, giving it the popularity attributed to it. The present research work was carried out with the objective of optimizing the production of soursop through the application of micronutrients (Zinc, Manganese and Boron) important for the nutrition of the plantations. The evidence of the improvement of the crop by the nutritional contribution is determined by the size of the fruit, quantity of aborted flowers and time of fruit formation. It is clear from the research literature that the use of micronutrients: Zinc, manganese and boron in the cultivation of soursop plants result in positive effects on it, since these micronutrients either separately or together contribute to photosynthesis, flowering, plant development and fruit production, in turn perform an adequate control of nutrition that is being carried out in the plant from its initial stage, it is necessary since the deficiency or excess of these micronutrients would have a detrimental effect on the development of plants and therefore the fruit.

El ámbito de frutas exóticas, actualmente se encuentra en crecimiento debido asu gran potencial, sin embargo, requiere de cuidados para garantizar unaproducción de calidad. La guanábana es una de las frutas tropicales másconocidas en el país, es muy consumida por sus beneficios medicinales, altovalor nutritivo y la cantidad de alimentos que se obtienen de su uso. Losprincipales sectores de producción se encuentran en la Península de SantaElena y Guayas, sin embargo, existen varias zonas del país donde crecen deforma endémica, dándole la popularidad que se le atribuye. El presente trabajoinvestigativo se realizó con el objetivo de optimizar la producción de guanábanaa través de la aplicación de micronutrientes (Zinc, Manganeso y Boro)importantes para la nutrición de las plantaciones. Las evidencias de la mejoríadel cultivo por el aporte nutritivo se determinan por el tamaño del fruto, cantidadde flores abortadas y tiempo de formación del fruto. Lo expuesto en la literatura de la investigación realizada deja claro que el uso de los micronutrientes: zinc, manganeso y boro en el cultivo de las plantas de guanábana dan como resultado efectos positivos en la misma, dado que estos micronutrientes ya sea por separado o juntos contribuyen en la fotosíntesis, floración, desarrollo de la planta y producción de los frutos, a su vez realizar un control adecuado de la nutrición que se está llevando a cabo en la planta desde su etapa inicial, es necesario ya que la deficiencia o exceso de estos micronutrientes tendrían un efecto perjudicial en el desarrollo de las plantas y por ende del fruto.
