Summary
The comparative influence of GA and of plant population on distributión of tuber size was evaluated for 3 years. Both closer seed spacing and treating seed with GA resulted in a reduction in tuber size without marked changes in total yield. However, with a growing season of 97 days, yield of U. S. No. 1 tubers from GA-treated seed was lower than from nontreated seed. Cost of seed required to achieve a denser plant population compared to cost of treating seed with GA was approximately $69 versus $1 per acre.
Resumen
La influencia comparativa de ácido jiberélico y de la populatión de plantas sobre la distributión del tamaño de tubérculos fué evaluada durante 3 años. Ya sembrando la semilla a distancias menores como tratando la semilla con ácido jiberélico tuvo como resultado la reduction en tamaño de tubérculos sin cambios mercados en el rendimiento total de tubérculos. Sinembargo, con una estación de crecimiento de 97 días, el rendimiento de tubérculos de U.S. No. 1, obtenidos de semilla tratada con ácido jiberélico, fué menor que el rendimiento obtenido de semilla no tratada. El costo de semilla requerida para obtener una populatión más densa, comparado al costo de tratar la semilla con ácido jiberélico fué $69 (US) contra $1 (US) por acre.
