Abstract

Dry weight of tops of LaRouge potatoes varied considerably among years. In turn this affected tuber growth and total plant dry matter accumulation. Maximum plant top dry matter accumulation occurred between 54 and 69 days after planting (DAP) with a maximum of 2.5 dry mt/ha. In all years tuber initiation was first observed 47–48 DAP. By 100 DAP, additional tuber growth was minimal. Among years, the highest tuber dry matter recorded was at 7.9 mt/ha. Of the variables that were evaluated for their effect on final yield and tuber growth rate (kg/ha/day), plant age in terms of DAP explained over 87% of yield variability. For most of the yield variables, the quadratic and cubic terms for DAP were significant in explaining variability. An additional 1 to 5% was explained by temperature variation. Between 95 and 99% of the variability in harvest index, the ratio of dry tuber to whole plant dry weight, was explained by DAP.

Resumen

El peso seco de papas de la variedad LaRouge fue variable durante cada año. En consecuencia, el desarrollo del tubérculo y la acumulación total de materia seca en la planta fue también variable. Acumulación máxima de materia seca (2.5 materia seca%ha) en la parte aérea de la planta ocurrió a los 54 y 69 días DDS después de la siembra. Durante todos los años la iniciación de los tubérculos fue observada a los 47–48 DDS. Crecimiento adicional de los tubérculos fue mÍnimo a los 100 DDS. La más alta acumulación de materia seca en el tubérculo fue de 7.9 mt/ha. La edad de la planta en términos de DDS causó el 87% de variabilidad en la producción final y en la rata de crecimiento del tubérculo (kg/ha/day). Para la mayorÍa de la variables de crecimiento, las formas cuadráticas y cúbicas de DDS fueron significativas. Un porcentaje del 1 al 5% adicional se explica por la variación de temperatura. Entre el 95% al 99% de la variabilidad observada en el Índice de cosecha, y en la proporción de materia seca entre el tubérculo el y peso seco de la planta, fueron explicadas por DDS.
