Abstract
Abstract An alternative that can be used to reduce the impact of drought stress is the addition of micro-nutrients, one of which is Zn. Zn application on several plants has been done and showed an increase in the ability of plants to deal with drought stress. However, the application of Zn in drought tomatoes has not been well investigated. Therefore, the research aims to study the application of ZnSO 4 on root and shoot growth of drought tomatoes. The study used two factors, namely cultivar (‘Tyrana F 1 ’ and ‘Permata F 1 ’) and ZnSO 4 doses (0, 10, 20, 30 and 40 mg Zn kg -1 soil). The treatments were arranged in factorial based randomized complete block design. Drought conditions are applied by watering through once every eight days. The results showed a different response in a total root length in both cultivars within the ZnSO 4 application. ZnSO 4 application increased root dry weight; however, there is a no different response in the shoot growth of tomato under drought stress. Root dry weight increased 36.8-62.5% on application 20-40 mg kg -1 ZnSO 4 under drought condition.
