Resumen
El presente trabajo se realizó durante los meses de agosto a diciembre del 2015, en los terrenos de la Sra. Briones Mantuano Elvira. Los predios están ubicados en el Recinto “La Rinconada” del cantón Daule, provincia del Guayas.
Los objetivos de este experimento fueron: 1) Generar alternativas tecnológicas sobre el fosfito potasio en el cultivo de soya, para mejorar el rendimiento, calidad y rentabilidad del cultivo. 2) Determinar agronómicamente el efecto del fosfito potasio y su mejor dosis de aplicación en soya. 3) Realizar un análisis beneficio costo de los tratamientos utilizando los presupuestos parciales.
Como conclusión se consideró: a). Agronómicamente el efecto del fosfato de potasio en los tratamientos no difirieron estadísticamente entre sí, es decir presentaron características agronómicas similares. En la variable calidad de grano no se presentaron problemas, dentro de la escala se encontraron en los menores rangos y su mejor dosis de aplicación en los dos cultivares de soya estadísticamente, los mejores rendimientos de grano se los observó con dos aplicaciones al follaje de 1,5 L/ha de Foska.
b). El beneficio costo de los tratamientos económicamente el tratamiento más rentable correspondió para el tratamiento 3 (1.5 L/ha de Foska) aplicados foliarmente a los 15 y 30 días después del trasplante.
Se recomienda: a.) En el cultivo de Soya se recomienda la aplicación del fertilizante Foska vía foliar se recomienda aplicar 1.5 L / ha, en el recinto “La Rinconada” del cantón Daule. b) Realizar otros experimentos en otras localidades con el fin de corroborar los datos de la presente investigación. c) Validar estos resultados a nivel de finca de productores.
This work was carried out during the months of August to December 2015, on the grounds of Ms. Elvira Briones Mantovano. The properties are located in the campus "La Rinconada" Daule canton, Guayas province. The objectives of this experiment were: 1) To generate technological alternatives on potassium phosphite in the soybean crop, to improve performance, quality and profitability of the crop. 2) Determine agronomically the effect of potassium phosphite and best application rate in soybeans. 3) Conduct a cost benefit analysis of treatments using partial budgets. In conclusion it was considered: a). Agronomically the effect of potassium phosphate treatments did not differ statistically from each other, ie they had similar agronomic characteristics. In the variable quality grain no problems were presented, within the scale were found in the lower ranks and their best application rate in both cultivars statistically soybeans, the best grain yields are watched with two applications to the foliage of 1 , 5 L / ha Foska. b). The cost of treatment benefit economically more profitable treatment corresponded to treatment 3 (1.5 L / ha Foska) foliarly applied at 15 and 30 days after transplantation. It is recommended: a.) In the cultivation of Soya application of foliar fertilizer Foska is recommended is recommended to apply 1.5 L / ha, in the exhibition "La Rinconada" canton Daule. b) Carry out other experiments in other locations in order to corroborate the data from this investigation. c) To validate these results at the farm level producers.
