| POLLINATION | The transfer of pollen from the male part of a flower (stamen) to the female part of a flower (the style and stigma). |
| POTASSIUM (K) | Potassium promotes disease resistance and good development of carbohydrates, starches and sugars, and it increases fruit production. Potassium is a macronutrient. |
