Calcium plays a major role in plant resistance to disease. Calcium is part of a necessary group of macroelements that regulate and they maintain the structure and physiological stability of plant tissue, as well as cell division and growth. In fruits and vegetables, calcium is extremely important because it affects the firmness of the fruits and their quality in terms of preservation, storage and transport. Lack of calcium can negatively affect the development and quality of fruits, which can lead to various deformations, especially in vegetables. Calcium (Ca) stimulates the development of root hairs and the growth of the entire root system, and is also necessary for normal leaf growth. Calcium plays a major role in plant resistance to disease. After nitrogen (N), calcium has the greatest influence on the occurrence and development of the disease. The application of calcium can reduce the development of diseases in vegetables, besides affecting the yield and quality of fruits. Lack of calcium can cause indentation of the epidermis on the fruits of peppers, tomatoes, watermelon and cucumbers. Fruity vegetables include pumpkin, melon, cucumber, watermelon, pepper, tomato, blue tomato (eggplant) and squash.
Symptoms of calcium deficiency often appear quickly. First brown spots they usually become visible on older leaves within one to two weeks. The spots start as small, light brown dots that spread over time. After two weeks, the spots become larger on older leaves and often appear on the leaf edges, similar to symptoms of potassium deficiency or overfeeding. Calcium is poorly mobile or almost immobile in plants, and is transported very slowly, which often leads to a lack of this element. In order to eliminate the lack of calcium, it is recommended to apply nutrition through the leaves, that is, foliar nutrition. Foliar application is recommended when the lack of calcium is clearly visible in the plants, when the leaf mass is sufficiently developed and is carried out in the evening, in dry and calmer weather conditions.
Application of Calcium in fruitful vegetables
Wuxal Calcium is a liquid nutrient that is applied through the leaves and contains a high concentration of calcium, an increased amount of nitrogen and microelements. This nutrient is used in fruiting vegetables such as tomatoes, peppers, cucumbers and watermelons during the intensive period of fruit growth. One of the advantages of this preparation is that it can be mixed with many pesticides. Adding calcium to plants through foliar treatment in the phase of fruit development enables their normal growth, improves their structure, firmness and color. It also enables longer storage of fruit in warehouses and cold storage, as well as easier transportation.
