Summary
The results of a 10-year source of potash study indicate: 1) source of potash did not influence yield of potatoes, 2) sulfate and nitrate of potash were equal in their effect on the production of tubers of higher specific gravity than potassium chloride, 3) there was a trend for potatoes fertilized with potassium chloride to produce chips of lighter color than the sulfate and nitrate sources of potash, and 4) the higher rate of potash used resulted in lower specific gravity and a trend toward lighter colored potato chips.
Resumen
Los resultados de los estudios de 10 años, de fuentes de potasio indican 1) Las fuentes de potasio no influyeron en el rendimiento de la papa, 2) El sulfato y el nitrato de potasio, fueron ifuales en su efecto en la producción de tubérculos de más alta gravedad específica, que el cloruro de potasio, 3) Hubo una tendencia de las papas fertilizadas con cloruro de potasio, para producir ojuelas de color más claro, que aquellas en las cuales se aplicó sulfato y nitrato de potasio, y 4) le aplicación del nivel más alto de potasio usado, resutló en ojuelas de papa de menor gravedad especifica y con tendencia a ser de color más claro.
