Exacerbated by climate change, drought is a significant abiotic stress in the crop production sector that profoundly affects food security worldwide. White cabbage is classified as a moderately drought-sensitive crop. The role of folic acid (FA) or its derivatives (folates) in plant sensitivity to drought stress remains unclear. The study aimed to evaluate the potential of folic acid in enhancing specific growth parameters and physiological attributes of drought tolerance in cabbage seedlings. In this investigation, the effects of FA as a foliar application at 0, 100, and 200 µM (FA0, FA1, and FA2, respectively) were examined on white cabbage seedlings grown under full-irrigation (I0) and restricted irrigation (I1) treatment, which was adjusted to 50% of the I0 treatment. Drought stress adversely affected the plant growth properties of cabbage seedlings, whereas FA treatments mitigated the adverse effects of drought stress on the plant growth properties of cabbage seedlings. Under restricted irrigation, plants treated with 100 µM FA (FA1) had higher plant height, stem diameter and leaf area, while plants treated with 200 µM FA (FA2) had higher plant dry weight and plant dry matter content. Plant fresh weight increased with FA treatments under restricted irrigation, but no significant difference was observed between doses. On the other hand, leaf relative water content (LRWC), which decreased under restricted irrigation conditions, increased with FA applications regardless of the dose, while electrical conductivity (EC), which increased under the same conditions, decreased with 100 µM FA (FA1) application. Leaf number, root fresh weight, root fresh weight, root dry weight, root dry matter content and chlorophyll value (SPAD) were not affected by FA treatments under both restricted and full irrigation conditions. In conclusion, foliar spray of folic acid in cabbage can be recommended as a potential application to alleviate drought stress.
