The phenological observations during the growth period showed that the use of heat treated potato seed will lead to the more rapid plant emergence and flowering. The patterns of leaf and tuber development showed that no significant differences in tuber development but foliage development with the ones in two seed lots showed the difference. The potato crop produces a good leaf canopy once the foliage has met between the rows. This happened faster, if we used physiologically older seed. In practice it meant, that we missed one weed control cultivation. The yield and starch content with both lots where quite similar, but we met differences between varieties what was one of targets of the experiment. The climatic conditions in Estonia are favourable to produce satisfactory yield and high starch content ware crop. Non aged crops grown from normal seed crops as a late maincrop, senescing naturally in late September when harvest take place in cooler wetter conditions with an increased likelihood of tuber damage, disease infection and subsequent poor storage. The results with processed potato seed by thermal treatment showed that physiologically older seed produced a similar yield for harvest in early September and this can be done by growing crops which either senescing naturally or are defoliated by that time
