Efecto de la fertilización mineral, orgánica y foliar en la fenología del cultivo de café (Coffea arabica L.) En vivero y con diferentes variedades

Abstract

The objective of this study was to evaluate the percentage of germination and after that analyze the effect of mineral, organic and foliar fertilization on three varieties of coffee in nursery in the canton Calvas, Cango Bajo neighborhood. To improve the phenological development in the initial phase (height, number of leaves, stem diameter and root length). An experimental design of complete blocks was proposed. A survey of the main coffee cultivars in the neighborhood was carried out and the three main varieties were evaluated. To evaluate the physiological development, six measurements were performed every 21 days. The final results indicate that the typical variety had the highest percentage of germination and that the treatment MIN-Sol (Solid Mineral) responded better in the Caturra variety; While ORG (Organic) treatment gave better results in the varieties Típica and Caturra by improving the studied variables, both mineral and organic fertilizers produced good results with significant statistical differences. Indicating that in low doses, contribute to a better development of the seedlings, as opposed to not applying fertilizer.
