Abstract
Background: Bioproducts represent a promising alternative for sustainable agriculture, notable for their ability to stimulate plant growth and development, which positions them as valuable tools in current production systems. Objective: To evaluate the effect of complementary application of EcoMic®, QuitoMax® and CBFERT bioproducts on the productivity and seed quality of cowpea (Vigna unguiculata cv. INIFAT-93). Methodology: The research was conducted in experimental plots at the University of Pinar del Río (Cuba), using a randomized complete block design with four replications. Four treatments were evaluated: 1) 100% chemical fertilization (control); 2) 50% chemical fertilization plus EcoMic®; 3) 50% chemical fertilization plus QuitoMax® + CBFERT; and 4) 50% chemical fertilization plus the combination of all three bioproducts. Atharvest, biological productivity variables, agricultural yield components, and seed quality parameters (biomass and dimensions) were measured. Results: Analyses revealed that bioproduct treatments showed significant results: they enabled a 50% reduction in chemical fertilizer use, increased dry biomass production by 24%, and achieved agricultural yields exceeding 1.2 t ha-1. Regarding seed quality, biomass increased by 20-32% while maintaining dimensional variations below 6% compared to the control treatment. Implications: It is feasible to substantially reduce chemical fertilizer use in cowpea cultivation through complementary application of bioproducts, while maintaining or even improving crop production and quality parameters. Conclusions: Application of 50% chemical fertilization in combination with either EcoMic® or QuitoMax® + CBFERT significantly increased the biological and agricultural productivity of cowpea, ensuring seed quality comparable to that obtained with complete chemical fertilization. These results demonstrate the remarkable potential of these bioproducts for implementing more sustainable and efficient agricultural production systems.
