Bioestimulantes en el crecimiento y rendimiento de soya (Glycine max (L.) Merrill)

Taking into account the importance of soybeans culture in the world and particularly in Cuba, as well as the need to validate bioproducts which can increase their yields and preserve our environment, this work was developed. The aim was to evaluate the effect of the application of three biostimulants (Azofert-S ® , EcoMic ® and QuitoMax ® ) in the growth and yield of soybean cultivation cv. Incasoy-27. The experiment was conducted in experimental areas of the National Institute of Agricultural Sciences, in an agrogenic leachate Red Ferralitic soil. A randomized block design with eight treatments and four replicates was used, which consisted of sowing seeds without the application of biostimulant, as control, with the application of each biostimulant or their combination. A treatment with mineral fertilization was used. The biofertilizers were applied by seed coating and QuitoMax ® by its imbibition during 15 min. In flowering phase, growth and symbiosis variables were determined and at harvest time, the crop agricultural performance and its components were also determined. The results showed that the application of Azofert ® , EcoMic ® and QuitoMax ® stimulated nodulation, mycorrhizal colonization, growing and soybean yield.
