Abstract
Fluoride is present naturally in the environment and may reach levels that impair the bio-physiological processes in plants. The aim of the present study was to examine the effect of sodium fluoride (NaF) stress on the yield of Solanum melongena L., (aubergine, brinjal, eggplant), a member of the Solanaceae family with edible properties. In a pot experiment, lasting from August to October 2017, NaF was applied twice weekly as a soil drench and a foliar spray in concentrations of 100, 200, 300, 400, 500, and 600 ppm. The yield of S. melongena was severely affected by the NaF in a dose-related manner with the maximum yield reduction observed at 600 ppm NaF. The soil drench affected the plants more than the foliar spray application. The results showed that S. melongena is a salt sensitive crop.
