Abstract
Studies on solution heating and intermittent solution circulation in nutrient film culture have established suitable regimes for producing high yields of good quality tomatoes.
It is recommended that solution temperature should be maintained at 15–18°C before picking starts to ensure high fruit quality and raised to 25°C subsequently to increase root and shoot growth and fruit yield.
The greatest benefit from intermittent solution circulation is a marked improvement in the quality of fruit picked early in the season.
Fifteen minutes of circulation for every 0.6 MJ of total radiation received within the glasshouse in winter gave the best results.
