What are the causes of poor growth in white radish (daikon)

1. Pithiness: Pithiness is also called hollow heart. The main causes of pithiness during cultivation are high temperature and drought, excessive nitrogen and insufficient potassium, overly rapid growth and delayed harvest. The main cause of hollow heart during storage is dry storage air.

2. Black skin and black heart: The main causes of black skin and black heart in radish during cultivation are hard soil, poor aeration and the application of undecomposed barnyard manure, which causes intense microbial activity and leads to oxygen deficiency in the roots.

3. Cracking: The main cause of cracking in radish roots is uneven water supply during the growth of the fleshy root, first dry and then wet.

4. Branching: The main causes of branching in radish are old seeds, damaged radicle, shallow soil layer, compacted soil, and an abundance of gravel and tile fragments in the soil, as well as inadequately decomposed base fertilizer or improper fertilization.

The above are the causes of poor fleshy root growth that can occur during radish cultivation. If these phenomena are found, corresponding targeted measures should be taken to achieve good quality and high yield.
