A research on the determination of water-yield relationship in processing tomato plants

The fresh water resources in the world including Turkey are decreasing day by day. In order to solve the problem, especially in agricultural production, various studies are being carried out to use the water more effectively. This study is conducted on processing tomato, which has a significant production area in terms of our country, is one of them. In this study is carried out during the summer season of 2017 under the conditions of İzmir-Bornova. The aim of the study determinates the water-yield relations plus some fruit quality characteristics, plant growth parameters, water-yield response factor, water use efficiency and irrigation water use efficiency. Kendras F1 industrial tomato type was taken as material and random blocks experiment design was applied in this research. Pan evaporation was used for the determination of the amount of irrigation water and irrigation treatments were applied as I125, I100, I75 and I50 (125%, 100%, 75% and 50%, respectively). In the result of the study was obtained the amount of yield also increased when the irrigation water increased. On the other hand, some fruit quality characteristics such as the titratable acid, the amount of water-soluble dry matter, the fruit dry weight, the fruit hardness, the color of the fruit shell (a*/*b) and pulp EC increased due to the decrease in the amount of irrigation water. According to these results, with changes on the basis of years, it is thought that I75 subject more advantageous for farmers due to it will more income to the farmers with the yield x quality (briks) value.
