Abstract
The application and use of local bioproducts for the benefit of agriculture is expanding very strongly in Cuba. It represents a necessary practice, aimed at improving crop efficiency, substituting imports and achieving food sovereignty. Tomato (Solanum lycopersicum L.) is one of the vegetables in greatest demand; its production with national bioproducts such as Fitomas EC and Gluticid constitutes an alternative to the lack of financing that limits its production. In this sense, an experiment was designed with the objective of evaluating the effect of the combined application of Fitomás-EC® and Gluticid®, as stimulators of tomato yield. The study was carried out on an Agrogenic Red Ferralitic soil under field conditions, in the experimental areas of the National Institute of Agricultural Sciences (INCA). Four treatments were studied under a randomized block design with four replications. Both bioproducts were applied by foliar spray at a rate of 6 g L-1 and 2.8 ml L-1 respectively. The results obtained showed a positive response on performance and its components. Fitomas-EC® and Fitoglu treatments achieved a statistically superior performance than the control. Both stimulated the number of clusters and flowers, as well as crop productivity by 44 and 49 % respectively with respect to the control. The variables evaluated in each of the phenological stages showed positive results between both bioproducts, which is why their combined application is proposed.
