What will happen to yield in case of K deficiency
A lack of K can lead to a reduction in the number of grains in the panicle and in their mass, as well as to the development of feeble grain.
K deficiency can cause plants to have wilting leaves and, in the worst case, to die.
K deficiency leads to weakened stems and, consequently, to lodging of the crop.
A lack of K leads to the formation of small maize cobs with pointed tips. Stems are prone to lodging.
Older sugar cane leaves subject to K deficiency, can develop chlorosis and rotting of the tips and edges of leaves.
Following K deficiency, sunflower plant stems become weak and thin, while the fat and fatty acids content in the seeds decreases.
One of the most obvious signs of a K deficiency in potatoes is slowing growth, disturbance of flowering and a bluish-green colour of leaves. Plants shorten, their leaves droop, turn yellow and become blotchy.
