Other claims from this paper (10)
- Intervention effect Pre-planting 24°C day and 17°C night temperature produced plants taller, heavier and leafier than 21°C day and 19°C night.
- Association In the first 12 weeks of harvesting, larger plants produced significantly more fruit than their smaller counterparts.
- Association In the first 12 weeks of harvesting, larger plants had higher gross monetary returns than their smaller counterparts.
- Association After 20 weeks of harvesting, plants from the two pre-planting temperature treatments produced similar weights of marketable fruit.
- Intervention effect Raising the 24-h mean air temperature by 1°C in the early post-planting stage increased total (20 week) yield by 1.17 kg m-2.
- Association Earliness and total fruit weight after four weeks of harvesting were linearly related to mean post-planting temperature.
- Association In the early post-planting period, total leaf area and stem length increased with 24-h mean temperature.
- Association After 20 weeks of harvest, gross monetary returns and profitability were highest when the early post-planting mean temperature was high.
- Intervention effect Restricting stem fruits to one per leaf node produced no significant difference in yield or quality of fruit.
- Association Day and night temperature amplitude had no effect on cucumber.
