Extract

Taking into consideration the whole of this experiment, as reported in this and the two preceding papers, the following are the salient conclusions.

1. Of the various plant criteria tested, the height of plants at about the 45th day after planting, and the weight of all tubers produced, are the two most useful criteria. Eelworm criteria are conveniently analysed in logarithmic transformation.

2. In the first season the presence of numerous eysts of Heterodera rostochiensis had no detectable effects on the growth or yield of the potato plants. Plants grown in the same soil without further treatment in the second year both were shorter and produced a much smaller crop than the uninfected.
