Abstract

DROUGHT is the most important limiting factor for plant growth and crop production. In this study, resistance of 2 olive cultivars including MAHALI BAGHMALEK and ZARD to the DROUGHT was investigated by using different irrigation treatment (I1: watering when 0-3% of the plants available water was used. I2: watering when 33-66 % of the plants available water was used. I3: watering when 66-100 % of the plants available water was used), three potassium levels (0, 50 and 100g POTASSIUM SULPHATE for each plant at planting time in pot). The experiment was carried out in a completely randomized design with factorial arrangements with four replications. Measured parameters included crop WATER POTENTIAL, leaf RELATIVE WATER CONTENT and accumulation N, P and K elements in leaf and root. The results showed that crop WATER POTENTIAL in cv. MAHALI BAGHMALEK was lower than cv. ZARD, but its RELATIVE WATER CONTENT was higher. In both cultivars, WATER POTENTIAL and RELATIVE WATER CONTENT were reduced with decreasing of irrigation. The best RWC and WATER POTENTIAL was related to I3 water treatment As well as N, P and K elements in leaf were lower in I3 treatment. Use of potassium led to the increase of the RELATIVE WATER CONTENT and decrease of the plant WATER POTENTIAL. The best RWC and the lowest WATER POTENTIAL were related to K1 potassium treatment (100 g POTASSIUM SULPHATE). Potassium fertilization led to increasing potassium of the root and leaves in each cultivar, but did not show significant effect on N and P in the leaf and root.
