Abstract

The effect of thermal screens on the energy budget, is the mutual effect of physical and biological factors.
There is partly the direct effect of reduced heat loss but also the effect on the time rate to produce an equivalent amount of plant mass.

The preliminary analyses of the results after one season, shows that those aspects may be taken into account in the interpretation of the final results of the treatments.
