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. |
| 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. |
| Zinc (Zn) | Auxins synthesis. |
| Copper (Cu) | Influences in the metabolism of nitrogen and carbohydrates. |
| Molybdenum (Mo) | Component of nitrate-reductase and nitrogenase enzymes. |
- Endoplasmic Reticulum
Endoplasmic ReticulumThe endoplasmic reticulum is a network of sacs in the cytosol of eukaryotic cells that manufactures, processes, transports, and stores chemical compounds for use inside and outside of the cell. The endoplasmic reticulum (ER) is an...

- Vegetables Nutrient Requirement For Specific Yields
Plant Nutrition is the study of the chemical elements and compounds that are necessary for plant growth, and also of their external supply and internal metabolism. In 1972, E. Epstein defined two criteria for an element to be essential for plant growth:In...
- Role Of Potassium In Crop Yield
Potassium is vital to many plant processes. A review of its role involves under-standing the basic biochemical and physiological systems of plants. While K does not become a part of the chemical structure of plants, it plays many important regulatory...
