Maximum potential potato yield in the Columbia Basin, USA: Model and measured values

Abstract

Maximum yields of potato tubers for growing conditions in the Columbia Basin, Washington, USA were estimated using two methods. The first was based on experimental data from a large number of experiments conducted each year from 1959 through 1973 with Russet Burbank potatoes. The highest yielding plots each year were selected, and boundary analysis was used to determine the relationship between growing season length and maximum yield. Maximum yield was found to be related to growing season length by Y = D - 36 where Y is tuber yield in t/ha and D is days since planting. The second method was based on a model which assumes that dry matter production of a crop is proportional to intercepted radiation. This model has been validated for Scottish growing conditions. The solar radiation conversion efficiency for Russet Burbank potatoes under Columbia Basin conditions was found to be 1.35 g/MJ, using boundary analysis. The model gave better agreement between predicted and measured boundary values than did the simpler model based only on growing season length. Agreement was better, particularly at the end of the growing season when days were shorter and cooler than in the summer. Maximum measured yield was 124 t/ha. The simple model predicted maximum yields around 160 t/ha, while the MW model predicted maximum values around 140 t/ha.

Compendio

Los rendimientos máximos de tubérculos de papa las condiciones de cultivo en la cuenca del Columbia, Washington, USA, fueron estimados utilizando dos métodos. El primero se basaba en datos experimentales obtenidos de un gran número de experimentos conducidos cada año desde 1959 hasta 1973, con papas de la variedad Russet Burbank. Cada año se seleccionaron las parcelas que habían tenido los más altos rendimientos, y se utilizó el análisis de límite para determinar la relación entre la longitud de la temporada de cultivo y el máximo rendimiento. Se encontró que el máximo rendimiento estaba relacionada a la longitud de la temporada de cultivo de acuerdo a Y = D-36, donde Y es el rendimiento en tubérculos en t/ha y D es el número de días a partir de la siembra.

El segundo método se basaba en un modelo que asume que las producción de materia seca de un cultivo es proporcional a la radiación interceptada. Este método ha sido reconocido como válido para las condiciones de cultivo escocesas. La eficiencia de conversión de la radiación solar para las papas Russet Burbank bajo las condiciones de la cuenca del Columbia fue de 1,35 g/MJ, utilizando el análisis de límite. El modelo dió una mayor concordancia entre los valores pronosticados y aquellos obtenidos utilizando límite en comparación con los valores obtenidos utilizando el modelo sencillo basado sólamente en el longitud de la temporada de cultivo. La concordancia fue mayor particularmente al final de la temporada, cuando los días fueron cortos y más fríos que en el verano. El rendimiento máximo medido fue 124 t/ha. El modelo sencillo permitió pronosticar rendimientos máximos cercanos a 160 t/ha, mientras que el modelo MW arrojó un pronóstico con valores próximos a las 140 t/ha.
