Abstract:
A method is described which can be used to estimate the most economical night-time greenhouse temperature for a particular crop. The method requires growth data, engineering data and economic data to produce a solution. Most critical are the growth data, which probably limit the usefulness of the method at the present time. An example is presented to illustrate the method. Growth-chamber data for tomato seedlings are used to obtain the sensitivity of that crop to deviations from the physiologically optimal night temperature. The available data seem to indicate that a 12 K deviation from that optimum results in a yield decrease of 20%. The recommended night temperature in the example is about half-way between the physiological optimum and the outside temperature. © 1984.

Optimal night temperatures for greenhouse seedlings
A method is described which can be used to estimate the most economical night-time greenhouse temperature for a particular crop. The method requires growth data, engineering data and economic data to produce a solution. Most critical are the growth data, which probably limit the usefulness of the method at the present time.

Growth-chamber data for tomato seedlings are used to obtain the sensitivity of that crop to deviations from the physiologically optimal night temperature.
