Abstract
It is possible to restrict the vegetative growth of early protected tomato crops, growing in the nutrient film technique (NFT) water culture, by supplying the nutrient solution intermittently instead of continuous flow.
Intermittent flow regime given up to anthesis of the fourth truss, increased early yield but did not increase the final total yield.
There was a highly significant decrease in root fresh weight.
Also, a reduction in all intermittent treatment of water consumption 22%, was noticed under the intermittent flow.
The water use efficiency calculated on the basis of fresh and dry weights increased under intermittent treatments.
