BUSTAMANTE-GONZALEZ, Carlos Alberto. Effect of FitoMas-E application on the production of Coffea canephora Pierre ex Froehner. cultrop [online]. 2023, vol.44, n.2  Epub 01-Jun-2023. ISSN 1819-4087.

During October 2013 to March 2017, in areas of the Agro-Forestry Research Institute at the Tercer Frente Experimental Station, Santiago de Cuba province, the biostimulatory effect of FitoMas-E was studied on the yield of Coffea canephora Pierre ex Froehner grown at 3 mx 1.5 m on brown soil under the shade of Samanea saman and Gliricidia sepium. The treatments were FitoMas-E (FM); FM + N18.85 P12.5 K20 (25 % of the control); FM + N37.5 P25 K40 (control 50 %); FM + N56.3 P37.5 K60 (control 75 %) and N75 P50 K80 - Control. The biostimulant was applied at a dose of 1.0 L ha-1 and was fractionated in the phenological phases of flowering, fruit filling and harvest. 60 % of nitrogen and potassium as well as phosphorus 100 % was applied in the months of April-May while in the second application 40 % of the dose of nitrogen and potassium. The production of cherry coffee per plant was evaluated and it was extrapolated to a ton of coffee gold per hectare. FitoMas-E application stimulated the yield of the coffee tree. Significant differences were found between treatments in all the experimental years and in the accumulated harvest. The FitoMas-E application to Coffea canephora in the first three years after low pruning in a Brown soil provided high and stable productions of this species with yield accumulated higher than inorganic fertilization and the best benefit/cost ratio, which constitutes an alternative to mineral fertilization with national inputs.
