EFFECT OF HARVEST DATE ON YIELD OF PROCESS TOMATOES

A.P. Julian, K.J. Fisher, M.A. Nichols
Few trials with process tomatoes for machine harvesting consider the effect of harvest date on red-ripe fruit yield. Usually an arbitrary decision is made to harvest the trial on the basis that the crop "appears" to be fully mature.

It is suggested that results based on such decisions could be misleading and that to accurately determine treatment effects it may be necessary to take a number of sequential destructive harvests. Such information would also provide data on the field storage ability.

In one study in which destructive harvesting was carried out at weekly intervals the yield of ripe fruit was found to follow a normal distribution. (Fig 1 & Fig 2).
