What happens due to sugarcane K deficiency?

Sugarcane K ( potassium ) results in formation of slender stalks as a result of slowed growth, yellowing, and marginal drying of older leaves. The elder lower leaves take on an orange, yellow hue as they acquire multiple chlorotic patches that eventually turn brown with a dead centre. The epidermal cells of the upper surfaces and midribs of the leaves have a crimson colour. The juvenile leaves appear to have formed from a single point, creating the impression of a “bunched top.” Root development is poor, with fewer root hairs.
