Research Abstract

We tried to grow tomatoes hydroponically with mineralization of the fish extract in bed or outside bucket. Vegetative growth in control is more than those in the fish extract slightly. K and Ca concentrations in top leaves are less and no difference about the occurrences of blossom-end rot fruit between treatments. Normal fruit rate and quality of fruit were not different. Fruits yield in control are 2,56kg, these of the fish extract are 90 from 94% of control. TTC reducing activity of roots was slightly higher values in the fish extract. The growth rates of shoot in control are slightly larger compared to the fish extract groups, but those of root did not differ between treatments.
