Evaluation of four doses of liquid biofertilizer enriched with mineral salts

The research was carried out at the Experimental Station of the Faculty of Agronomic Sciences University of El Salvador. The variables evaluated were Independent variable: dose of supermagro liquid biofertilizer and a control. Dependent variable: Tomato crop yield: indicators: stem diameter height and number of flowers per plant number diameter and weight of fruit per plant. The analysis of results was carried out with the INFOSTAT statistical software in which an analysis of variance was applied with a comparison of groups using the Tukey and kruskal Wallis test. Tukey''s test for parametric variables with a behavior of normality and equality and kruskal Wallis test for non-parametric variables with a significance level of 5%. In order to determine the dose that gave the best results in terms of production and economic benefit.
