Abstract

Potato plants of Russet Burbank, Oromonte and Red McClure varieties were studied in the San Luis Valley of Colorado to determine their dry matter and nutrient accumulation. The following observations were made in the 1967 growing season.
  1. 1.

    Growth patterns for the three varieties were similar, but average growth rate of Oromonte and Red McClure was higher than that of Russet Burbank.

     
  2. 2.

    Top growth reached its peak in 61, 55, and 50 days after emergence for Russet Burbank, Oromonte and Red McClure, respectively.

     
  3. 3.

    In the 3 weeks before killing forst, tuber growth equalled 50% of maximum tuber dry weight for Russet Burbank and about 61% for Oromonte and Red McClure.

     
  4. 4.

    Total N uptake with a yield of 300 cwt per acre was about 127 lb for each variety, assuming a linear relationship between tuber yield and nitrogen uptake. The tubers contained about 71% of the total N uptake.

     
  5. 5.

    Total P uptake with a yield of 300 cwt per acre was about 16 1b for each variety, assuming a linear relationship between tuber yield and P uptake. The tubers contained about 83% of total P uptake.

     
  6. 6.

    Total K uptake with a yield of 300 cwt per acre was 132, 187, and 147 lb (not significantly different) for Russet Burbank, Oromonte and Red McClure, respectively, assuming a linear relationship between tuber yield and K uptake. The Russet Burbank tubers contained 63% of the total K uptake and Oromonte and Red McClure about 52%.

     
  7. 7.

    Tuber dry matter per cent increased during the season until 2 weeks before a killing frost (65 to 69 days after emergence). At harvest, the dry matter approximated 21% for the varieties studied.

Resumen

Plantas de papa de las variedades Russet Burbank, Oromonte y Red McClure fueron estudiadas en el Valle de San Luis de Colorado para determinar su materia seca y la acumulación de nutrientes. Durante la estación de crecimiento de 1967 se han hecho las siguientes observaciones.
  1. 1.

    Los modos de crecimiento de las tres variedades fueron similares, pero la tasa pramedia de crecimiento de Oromonte y Red McClure fué más alta que la de Russet Burbank.

     
  2. 2.

    El crecimiento de la parte vegetativa alcanzó su máximo en 61, 55, y 50 días después del brote para Russet Burbank, Oromonte y Red McClure respectivamente.

     
  3. 3.

    Durante las tres semanas antes de la helada, el crecimiento de tubérculos era igual a 50% del peso máximo seco del tubérculo para Russet Burbank y 61% para Oromonte y Red McClure.

     
  4. 4.

    La absorción total de N para un rendimiento de 300 cwt por acre fué de más o menos 127 lb para cada variedad suponiendo una relación linear entre el rendimiento de tubérculos y la absorción de N. Los tubárculos contenían acerca de 71% del total N absorbido.

     
  5. 5.

    La absorción total de P para un rendimiento de 300 cwt por acre fué acerca de 16 lb para cada variedad suponiendo una relación linear entre el rendimiento de tubérculos y la absorción de P. Los tubérculos contenían acerca de 83% del total P absorbido.

     
  6. 6.

    La absorción total de K para un rendimiento de 300 cwt por acre fué de 132, 187, y 147 lb (sin diferencia significante) para Russet Burbank, Oromonte, y Red McClure respectivamente, suponiendo una relación linear entre el rendimiento de tubérculos y la absorción de K. Russet Burbank contenía 63% del total K absorbido y Oromonte y Red McClure acreca de 52%.

     
  7. 7.

    El porcentaje de la materia seca de los tubérculos incrementó durante la estación hasta dos semanas antes de la helada (65 a 69 días después de la germinación). Al tiempo de la cosecha la materia seca era más o menos 21% en las variedades estudiadas.
