Tomatoes crack their fruit in the late stages of growth and can be caused by several reasons:
Improper water management: If tomatoes encounter rapid water changes during fruit development, especially during the rapid fruit expansion period, heavy rain or excessive irrigation, it is easy to cause the peel tension to exceed the limit and crack. Conversely, sudden and heavy watering after a prolonged drought can also lead to fruit cracking.
Improper use of fertilizers: Excessive application of nitrogen fertilizer can encourage the plant to grow vigorously, resulting in faster cell division in the fruit, and if the water supply is insufficient at this time, uneven fruit growth may also cause fruit cracking. Potassium fertilizer plays an important role in improving the quality and stress resistance of tomatoes, and potassium deficiency can also lead to fruit cracking.
In order to avoid the occurrence of fruit cracking, reasonable water and fertilizer management measures should be taken, suitable varieties should be selected, and appropriate shading and cooling measures should be taken in the high temperature season, and the prevention and control of pests and diseases should be strengthened.
