Abstract
In a continuing experiment, at two locations in Ontario, continuous Norchip and Kennebec potatoes are being compared for profitability with rotations including potatoes followed by malting barley or grain corn or soybeans. At the end of the first seven-year cycle Kennebec may have started to decline in yield in continuous production, but continuous potatoes remains the most profitable cropping sequence.
Resumen
En un experimento que aún continúa en dos localidades de Ontario, se está comparando el cultivo continuo de papa de las variedades Norchip y Kennebec en cuanto a rentabilidad, con rotaciones que incluyen papa, seguida de cebada para malta o maíz, para grano o frijol soya. Al término del primer ciclo de siete años, la variedad Kennebec puede haber comenzado a declinar en rendimiento en el régimen de cultivo continuo, pero sin embargo, el cultivo continuo de papas sigue siendo la más rentable secuencia de cultivo.
