Fertilización potásica de papa (Solanum tuberosum L.) en cultivo bajo riego
The objective of this research was to study the effect of potassium fertilization on potato. During October 1979 — March 1980 measurements of yield, tuber quality and starch content were made in a field experiment on irrigated soils of the Lower Valley of the Colorado River (Province of Buenos Air...

El objetivo de esta investigación fue estudiar el efecto de la fertilización potásica sobre la papa. Durante octubre de 1979 - marzo de 1980 se realizaron mediciones de rendimiento, calidad del tubérculo y contenido de almidón en un experimento de campo en suelos irrigados del Valle Inferior del Río Colorado (Provincia de Buenos Aires, Argentina). Los tratamientos consistieron en: (0) testigo; (1) 100, (2) 1,50 y (3) 200 kg K2 Olha y los resultados obtenidos mostraron. 1) La respuesta del rendimiento a la aplicación de potasa fue estadísticamente significativa. 2) La fertilización con 200 kg 1(20/ha dio el mayor rendimiento. 3) El rendimiento total en cada tratamiento se correlacionó con la dosis de potasio aplicada; el coeficiente de correlación fue r = 0.77 4) Al aumentar las dosis de potasio hubo un incremento en la producción de los tubérculos de mayor tamaño (grupo A) y hubo una disminución en la producción de los tubérculos de menor tamaño (grupos C, y 5). El coeficiente de correlación entre el rendimiento de los tubérculos del grupo A de mayor calidad comercial y el potasio aplicado fue significativo (r = 0,75).5) El contenido de almidón en los tubérculos no fue significativamente diferente a lo largo de los distintos tratamientos aunque fue ligeramente superior en los tratamientos control al igual que su contenido de materia seca. 2022-09-06T17:23:41Z 2022-09-06T17:23:41Z 1983-01 Artículo https://repositorio.catie.ac.cr/handle/11554/11970 openAccess es Turrialba; Vol. 33, no. 1 8 páginas application/pdf Instituto Interamericano de Cooperación para la Agricultura (IICA) |
