At the coffee nursery of Puriales Business Basic Unit, San Antonio del Sur municipality, Guantánamo province, were developed three experiments during three campaigns of seedlings production (April-September/2012, October/2012-March/ 2013, April-September/2013). The objective was evaluating the FitoMas-E and EcoMic^® application for reduction of mineral fertilizer consumption in coffee tree seedlings production with adequate agricultural quality. The treatments by stage were: dose among 0,5 and 2,0 L ha^-1 of FitoMas-E; two organic substrate with the best FitoMas-E dose and simple and combined mycorrhizal; proportional reductions of the mineral fertilizer from 100 % to 25 % with mycorrhizal and FitoMas-E combination. A completely randomized design in parcels of 1,44 m2, and samples of ten plants for treatments was used. Simple ANOVA for experiments 1 and 3 and double ANOVA for experiment 2 were applied. The results showed the phytostimulant effect of FitoMas-E in the growth and development of coffee tree seedlings. The application of 1 L ha^-1 of FitoMas-E is the best-suitable for the evaluated growth variables (dry matter and foliar area). In the nursery final phase, the best behaviour was in the plants with combined application of mycorrhizal and FitoMas-E in all experiments, in coffee pulp as substrate. This combination allows the reduction until a 25 % the mineral fertilizer, with higher results compared to the application of 100 % of this fertilizer
