Evaluation of two biostimulants in soybean production

Abstract

The results of a study of soybean (Glycine max, (L.)) are presented, which was developed in areas of the Basic Sugarcane Seed Bank of the province of Cienfuegos, located in areas of the Espartaco community with the variety INIFAT- 70. The study was planted on May 24 and harvested on September 12 with 111 days, the application of biostimulants was carried out on July 19 at 55 days after planting, the randomized block design was used with 3 treatments (Control, FitomasEC and Fitomasplus) and 5 replicates, in plots of 36 m2. The seed used was basic from the bank itself with more than 95% germination and the study area was not fertilized. The treatments used were: Witness and/or control, FitomasEC an application at 2 liters ha-1, Fitomasplus an application 2.0052 liters ha-1 (tank mix 2 liters ha-1 of FitomasEC and 5.2 milliliters ha-1 of enerplant), The variables evaluated were ton ha-1 and the economic valuation. A simple classification analysis of variance (ANOVA) was performed and as there were significant differences between the treatments, the mean comparison test was performed using the multiple range test with Tukey's p<0.05 test. For data analysis, the statistical package Statgraphics Plus 5.0 was used. It was obtained as a result that the application of biostimulants increased soybean production, resulting significant with Fitomasplus, which achieved increases compared to the control of 25% and compared to FitomasEC of 22%, the Benefit/Cost ratio reported a positive effect of 1.02 for the FitomasEC and 1.25 for Fitomasplus with respect to the control.
