Currently, problems are reported in the quality of coffee (Coffea arabica L.) seedlings obtained in nurseries, a determining factor in the achievement of future highly productive plantations. A trial was carried out in 2020 at the CCS Juan Ramón Chávez in the municipality of Remedios, province of Villa Clara, with the aim of evaluating the effect of the bioproducts Enerplant, Nitrofix and Viusid agro on the quality of coffee seedlings in the nursery. For this, a completely randomized experimental design was established with five treatments that included the three bioproducts, an absolute control and a control where the provisions of the technical standards for the crop were applied, with three repetitions. The bioproducts were applied prior to the sowing of the seeds and when the seedlings reached the third pair of leaves. The percentages of germination at 50, 60 and 70 days after sowing were determined and the height, stem diameter, number of leaf pairs, leaf area and total dry mass of the seedlings were evaluated at seven months. The results show that the treatment with the bioproducts accelerates the germination of seeds and favorably stimulates the growth of coffee seedlings in the nursery, with increases between 35 and 48% in the leaf area with respect to the control without application, the best results are achieved when applying Nitrofix. The bioproducts applied contribute to raising the quality of the seedlings that are taken to the new coffee plantations.
