Other claims from this paper (10)
- Observation Effects of seed tuber weight were similar for different seed crop planting dates.
- Intervention effect Plants from small seed produced a smaller crop canopy than those from larger seed.
- Mechanism The later emergence from the smallest seed resulted from slower sprout elongation.
- Intervention effect Seed weight above 15 g did not affect stem emergence.
- Intervention effect Seed weight above 15 g did not affect canopy growth.
- Observation After severe frost, complete emergence returned within two weeks for all seed weights except 1–5 g.
- Intervention effect Tuber yields were little affected by seed weight above 5 or 10 g.
- Intervention effect Seed rates from 0·59 to 5·4 t/ha gave similar yields.
- Recommendation The authors suggest economic benefits from smaller seed tubers.
- Recommendation Small seed tubers from late-planted crops may reduce production costs and disease in seed tubers.
