Potato Research Aims and scope Submit manuscript

Summary

A simple method was required for estimating the proportion (H) of total dry matter production which is found in the tubers of a potato crop. The ratio (F) of tuber fresh weight to total fresh weight has been found to be a suitable estimator. The relationship is described by the equation: H=0.962 F+14.1. This single equation served to describe the relationship over a range of cultivars, crop maturity and crop water supply.
