Abstract
A field survey was conducted in 1979 to determine the accuracy of inrow spacing of five models of potato planters. Irregular seedpiece spacing expressed in terms of coefficient of variation (CV), was observed for all planters tested. The CV levels recorded in the survey ranged from 50.1% to 76.5%. The use of seedpieces of an optimum and uniform mass was effective in improving the accuracy of placement by a pick-type planter.
Resumen
En 1979, se hizo un estudio de campo para determinar la precisión de las distancias dentro de la hilera producidas por cinco modelos de sembradoras. En todas las sembradoras probadas, se observó un distanciamiento irregular de los tubérculos-semillas, expresado en los términos de un coeficiente de variación (CV). Los niveles de CV registrados en el estudio iban de 50,1% a 76,5%. La utilización de semilla de masa óptima y uniforme fue efectiva para mejorar la precisión de ubicación de una sembradora con pinches.
