Abstract:
The aim of the research was to determine the effect of irrigation interval on chlorophyll fluorescence of tomato (Lycopersicon esculentum Mill) under sprinkler irrigation using Compact Violet Laser-Induced Fluorosensor (CVLIF) to measure leaf photosynthetic performance. Four irrigation intervals; one day (T1), three days (T2), five days (T3) and seven days (T4) were used. Parameters measured were: Soil moisture content before and after irrigation, T1 (4.7), T2 (4.5), T3 (5.4), T4 (4.2) and T1 (15.1), T2 (15.1), T3 (13.6) and T4 (11.7), respectively; Fluorescence decrease ratio (Rfd) at F690 and F740, T1(2.465), T2(1.690), T3(1.998), T4(1.702) and T1 (1.929), T2 (1.205), T3 (1.241), T4 (1.101), respectively and adaptability (AP), T1 (0.155), T2 (0.180), T3 (0.253), T4 (0.222). Irrigation interval of five days, using the same amount of irrigation water was physiologically (in terms of adaptability) better than 1, 3 and 7 and adaptability could be used as an effective parameter to estimate the water status of tomatoes under various environmental stress conditions.
