Are there any additional benefits of applying calcium to potatoes?
Calcium also mitigates the adverse effects of heat stress on potatoes. Under heat conditions, calcium supplemented crops produce a much higher yield than those which did not receive any calcium applications. Palta suggests that during heat stress, for the normal function of the stomata and cell expansion (growth), a certain level of calcium must be maintained. As opposed to many other minerals needed by the plant, calcium is considered non-toxic even at a high concentration.
