Petiole analysis and the nitrogen fertilization of Russet Burbank potatoes

  • B. R. Gardner
  • J. P. Jones


The effect of nitrogen rates on the yield of Russet Burbank potatoes was studied in field experiments in Idaho. Petioles were sampled at the 6-to-8 leaf stage and thereafter at two week intervals until mid August.

Petiole nitrate concentrations were very high early but decreased rapidly as the season progressed and declined to a very low level as the plants matured. The nitrate content of the petioles reflected the amount of N applied to both locations.

Nitrogen applications increased total yield and the quantity of the larger size tubers. A highly significant correlation was found between the early season petiole nitrate concentrations and total yield. Suggested ranges of petiole nitrate concentrations were developed as a guide to efficient N fertilization of Russet Burbank potatoes in Idaho.

El efecto de la dósis de nitrógeno en la cosecha de papas Russet Burbank fue estudiado en experimentas de campo en Idaho. Se muestrearon peciolos desde el estadío de 6–8 hojas y después a interválos de dos semanas hasta mediados de Agosto.

Las concentraciones de nitratos en los peciolos fueron muy altas inicialmente, pero decrecieron rápidamente a medida que progresaba la estación y declinaron hasta un nivel muy bajo, cuando las plantas maduraron. El contenido de nitrato en los peciolos reflejó la cantidad de N aplicado en ambas localidades.

Las aplicaciones de nitrógeno incremetaron la cosecha total y la cantidad de tubérculos grandes. Una correlación altamente significativa se encontró entre las concentraciones de nitrato a comienzos de la estación y la cosecha total. Rangos de concentraciones de nitratos en el peciolo fueron desarrollados como guía para la fertilization eficiente de papas Russet Burbank en Idaho.
