ABSTRACT
To know the effects of different doses of earthworm humus and bovine manure on the main performance indicators of the soybean crop, Glycine max (L.) Merrill, variety Incasoy-27, an experiment was developed in the spring season (April -July 2012) on a Cambisol soil of the Bayamo municipality. In harvest maturity a sample of 10 plants per plot was taken and were evaluated the following indicators: number of pods per plant, number of grains per plant, weight of 100 seeds (g) and agricultural yield was estimated (t ha-1). The data were processed by analysis of variance of double classification and, in case of significant difference between treatments; the Tukey test was used for p≤0.05 in the comparison of the means. The results showed a positive effect of the different doses of both fertilizers applied, reflected in the yield and its components, highlighting the earthworm humus in the dose of 6 t ha-1 with increases of the yield of 1.77 t ha-1 respect to the control.
