Evaluación de Diferentes Niveles de Vinaza Aplicados Basalmente en la Producción Forrajera del Medicago Sativa( ALFALFA)

Abstract

At the Experimental Station Tunshi, belonging to the Chimborazo Higher Education Polytechnic School, the productive behavior of alfalfa was evaluated during the pre-flourishing stage with the use of three poor thin wine levels (4000, 5000 and 6000 l/ha) applied basally , compared to a control treatment (without the poor thin wine application), using 12 experimental plots of 20 m², distributed under an DBCA. The experimental results were subjected to variance analysis and mean separation with the Tukey's test. It was determined that the application of 4000 l/ha statistically improved the botanical alfalfa behavior as there were plant heights of 69.02 cm, 30.94 stems/plant and 29.37% aerial coverage, while the productive parameters were not statistically different, however, numerically, with the application of 5000 l/ha higher responses were obtained with 74.65 and 17.57t/ha/year green forage and dry matter respectively. The poor thin wine application did not affect statistically the forage chemical composition presenting from 23.25 and 23.90% dry matter 17.24 to 18.10% protein, 5.20 to 5.70% fiber and from 2.33 to 2.40% ash. In the physical and chemical soil characteristics the poor thin wine application tends to neutralize the soil pH (7.0 to 7.2), reduces the organic matter content but increases NH4 and P2O5 content, while the poor thin wine use reduces the economic profitability; this is why it is recommended to evaluate the poor thin wine use measuring its effect on various cuttings after its application.
