Abstract
The study evaluated the effect of the biostimulant VIUSID Agro® on the growth of Coffea arabica L. seedlings under nursery conditions in Santiago de Cuba. The problem lies in the need to improve the quality of coffee seedlings, reducing costs without compromising their development, which is crucial for coffee production in Cuba. The objective was to determine the optimal concentration of VIUSID Agro® to maximize the growth of seedlings. A completely randomized design was used with six concentrations of the product (0.2 to 1.0 mL L⁻¹) and a control, applied monthly from the second to the fifth pair of leaves. Indicators such as height, stem diameter, leaf area, dry mass and quality index were evaluated.
The results showed that concentrations of 0.6 and 0.8 mL L⁻¹ were the most effective, increasing height by 24%, leaf area by 14%, and dry mass by 98%. The 0.8 mL L⁻¹ concentration also increased stem diameter by 19.5%. Application on the third and fifth pair of leaves reduced production costs by 67% compared to monthly applications. It was concluded that VIUSID Agro® significantly improves seedling growth, being a viable alternative to optimize coffee production in nurseries.
