What are the 6 factors affecting plant growth

The most important growth factors are:

In practice, all these factors are more or less equally important for plant growth. In consequence, growth rate is determined by the limiting factor! In greenhouses, all growth factors can relatively easily be controlled for optimal plant growth. However, when natural daylight is the limiting factor, the effect of optimizing the other factors is of limited value. By using supplemental growth light, all environmental factors can be optimized, resulting in the maximum benefit to plant growth.

Plants use growth light as an important energy source for plant growth.This is a photochemical process in which light energy is absorbed by pigments in the leaves.This energy is utilised for converting CO2 and water into sugars.This process is called Photosynthesis and can be represented as follows:

Carbon dioxide + water + growth light ➔ sugar + oxygen 6 CO2 + 6 H2O + growth light ➔ C6H12O6 + 6 O2
