In addition to the increase in crop productivity, it also brings greater accumulation of dry matter in the aerial part of wheat, highlighting the importance of the nutrient for the production of residual straw and, therefore, greater soil cover.
This fact can provide greater resistance for the crop to lodging and thus reduce the loss of productivity and quality of wheat. It can optimize the use of other nutrients, such as nitrogen for example.
Another important contribution of potassium is in terms of increasing the diameter of the wheat stalk. The increase in potassium doses can confer greater thickness of the wheat stalk.
Deficiency – Older leaves show yellowing and weakening at the tips and margins.
