Potato and Tuber Crops

Harvest

Berries are ready for harvest after about 6-7 weeks of pollination. After which seeds can be extracted. Das and Subramanyam (1976) reported that kinetin (6-furfury-laminopurine) and gibberellic acid (GA3) injected (0.1 ml of 1000 ppm solution) into fully developed berries help in quick ripening. Seeds from prematurely harvested berries are less dormant and less viable than seeds extracted from fully developed berries. The last formed berries should not be harvested as they contain more ill filled and immature seeds.
