Abstract
Earlier experiments showed that development and yield of a glasshouse grown tomato crop mainly depend on the 24 hour average temperature.
This temperature integrating concept was used to make more efficient use of base load heating.
In the control algorithm temperature integrating was not limited to a 24 hour-period.
This temperature integrating concept was used to make more efficient use of base load heating.
In the control algorithm temperature integrating was not limited to a 24 hour-period.
Temperatures were allowed to vary between 14 and 26 C. Plant response was compared with a control treatment with the same mean temperature but a fixed temperature regime.
Development, growth and yield of December sown tomatoes in the temperature integrating treatment were not different from the control.
Compared to the control, energy input by the base load heating system was higher at the expense of the energy input by the peak load system.
Total energy consumption seemed to be a little higher for the temperature integrating treatment.
