Pepper crop guide: Main functions of plant nutrients

Table 3: Summary of main functions of plant nutrients.

Nutrient Functions
Nitrogen (N) Synthesis of proteins (growth and yield).
Phosphorus (P) Cellular division and formation of energetic structures.
Potassium (K) Transport of sugars, stomata control, cofactor of many enzymes, reduces susceptibility to plant diseases and a-biotic stresses, counteracts salinity
Calcium (Ca) A major building block in cell walls, and reduces susceptibility to diseases.
Sulphur (S) Synthesis of essential amino acids cystin and methionine.
Magnesium (Mg) Central part of chlorophyll molecule.
Iron (Fe) Chlorophyll synthesis.
Manganese (Mn) Necessary in the photosynthesis process.
Boron (B) Formation of cell wall. Germination and elongation of pollen tube.
Participates in the metabolism and transport of sugars.
Zinc (Zn) Auxins synthesis.
Copper (Cu) Influences in the metabolism of nitrogen and carbohydrates.
Molybdenum (Mo) Component of nitrate-reductase and nitrogenase enzymes.
