The Development Of Technology To Adapt And Maximise The Drip Irrigation System
Trickle irrigation has found rapid acceptance in fresh tomato production. Tomatoes have shown a marked sensitivity to water stress, with irrigation increasing yields substantially. Trickle irrigation increased tomato yield when compared to sprinkler and/or furrow irrigation. It has also been effective in reducing the total water requirements for tomatoes. Although increased amount of water increase tomato yield, the important quality factors of total soluble solids and acidity, particularly for processing tomatoes, were found to be inversely related to yield increases from irrigation. This project investigated the effects of different irrigation regimes under the trickle irrigation, plastic mulch production system on fresh market tomato yield and fruit quality. Of particular interest was the effect of water restrictions late in the crop on the levels of total soluble solids.
