Effects of row spacing and plant populations on yields and tuber-size of potatoes

Summary

Field studies were conducted over a period of three years to compare effects of two row spacings and two plant populations on yields, tuber size, and quality of Norland, Red Pontiac and Kennebec potatoes. The two row spacings were the standard 38 inch rows and a “bed system” where three rows spaced 19 inches apart occupy a relatively flat topped bed that is straddled by tractors and implements. Distance between beds was 38 inches. The two plant populations were planted at 12,900 and 19,300 hills per acre.

Results did not indicate any advantage of the bed system of planting over the conventional spacing. The higher population generally resulted in slightly higher total yields and a greater number of small tubers.

Resumen

Estudios fueron conducidos en el campo durante un periodo de tres años para comparar los efectos de dos distancias entre surcos y dos poblaciones de plantas sobre el rendimiento, el tamaño de los tubérculos y la calidad de las variedades de papa Norland, Red Pontiac y Kennebec. Las distancias entre surcos fueron la normal de 38 pulgadas y un sistema de “lomo o cama” en el cual tres surcos espaciados a 19 pulgadas ocupan una cama relativamente plana en la parte superior, la cual se adapta al paso de tractores e implementos. La distancia entre camas fue de 38 pulgadas. Las dos poblaciones de plantas se sembraron a densidades de 12,900 y 19,300 tubérculos por acre.

Los resultatos no indicaron ninguna ventaja del sistema de cama sobre el de espaciamiento normal. La población más alta resultó con rendimientos logeramente más altos y un mayor número de tubérculos pequeños.
