Efecto de concentraciones de Enerplant® en la eficiencia nutricional de posturas de cafetos

Abstract

Establishing the proper use of the inputs that ensure the nutrition of coffee trees is essential to optimize their application. The objective was to investigate the effect of different concentrations of a biostimulant on the absorption and utilization efficiency of NPK by Coffea arabica L. seedlings. The experiment was conducted at the Tercer Frente Agroforestry Experimental Station, province of Santiago de Cuba, from December 2023 to July 2024. Concentrations of 0, 1, 2, 3 and 4 ml ha-1 of Enerplant® applied foliarly were studied. The absorption, utilization efficiency, absorption efficiency and translocation efficiency of nitrogen, phosphorus,and potassium were calculated. Data were processed using one-way analysis of variance, and means were compared using Tukey’s test (α= 0.05). Enerplant® increased leaf contents and nutrient absorption. The biostimulant concentration of 4 ml ha-1 increased nitrogen absorption by 29%, phosphorus absorption by 59%, and potassium absorption by 63% compared to the control. Increasing Enerplant® concentrations increased nutrient utilization efficiency but reduced absorption and translocation efficiencies.
