The experiments here recorded deal with the comparison of longitudinally cut seed tubers with whole ones. The results have confirmed those already obtained on the same subject in prior trials, namely, that whole seed tubers yield better than cut ones: a) When whole or cut seed tubers were mois tened before planting, a small, though not statistically significant increase in harvest was observed, possibly, due to fewer failures of germination. b) The cutting of seed tubers on the day of planting gave the lowest production, c) Whole tubers with weight equal to that of the cut halves produced the highest yields and are recommended for use in our conditions.
