Water and plant growthScience project video


The objective of this experiment is to determine the effect of different amount of water on plant growth. The experiment will be carried out by watering radish seeds with different amount of water daily and observing the rate of growth.


Plants require sufficient water for a healthy growth rate, but over--watering plants will result in slower growth

Water and plant growth

The amount of water required by a plant depends on the type of soil used, the size of the pot, the species of the plant and the age of the plant. The type and condition of soil determines its water retention properties . Soil that has good water retention properties will require less frequent watering. The size of the pot determines the amount of water that can be added to the soil in order to maintain a reasonable level of moisture.

The size of the leaves and stem of the plant determines the amount of water that the plant needs. The age of a plant is also important, as younger plants tend to require more frequent watering to maintain the moisture on the soil surface since their roots have not grown deep enough. On the other hand, older plants can be watered with more water and less frequently because their roots would usually have grown deep into the soil.
