Productive response of Glycine max to different doses of organic fertilizers in Cambisol soil

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 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
