The importance of phosphorus (P): it stimulates the development of roots, increases the protein content in the grains and acts on photosynthesis and respiration.
Phosphorus (P) deficiency begins with a darker green color on the edges of old leaves, evolving to purplish tones at the edges.
In addition to the leaves, the culms can also present these same symptoms. Phosphorus (P) deficiency affects corn pollination, resulting in small, failed and twisted ears.
