How Potassium plays a crucial role in castor crop?
It plays a crucial role in activating numerous enzymes that produce and transfer photosynthesis to storage organs and provide resistance to pests, diseases, and environmental stressors. It also helps in increasing the quality of the crop. The most widely used source of potassium is Muriate of Potash, as it is soluble in water and less expensive.
The recommended doses of potassium for both rain and irrigation are 20 and 40 kg K20 /hectare, respectively. In the case of rain-fed Castor beans, whole potash should be added to the basil. In the case of irrigation of Castor, half of the potassium is basal and the other half as top dressing with nitrogen.
