This work focuses on the study of the effect of lanthanum application on Rangpur lime (Citrus limonia Osbeck). The experiment was carried out in a greenhouse. Four different doses of lanthanum chloride heptahydrate (50 mg, 100 mg, 200 mg, 400 mg) per citrus plants were applied ninety-eight days after the sowing. The plants were collected three weeks following the application of the lanthanum chloride the plants. The optimal dose was 50 mg. The results showed that the citrus plant physiology changed with the application of lanthanum, i.e., depending on the dose, there is a beneficial or a harmful effect on the growth.
