Browning in Cauliflower is due to deficiency/excess of:

✅Explanation:
Browning in cauliflower, often referred to as "hollow heart" or "brown rot", is primarily caused by a deficiency of the micronutrient Boron. Boron plays a crucial role in cell wall formation and sugar transport within the plant. Its deficiency leads to the breakdown of tissues, resulting in the characteristic browning.
