The main sources of energy for the plant are:
Heat (12% of total)
Water (7% of total)
Light (8% of total)
Water used for irrigation and other purposes, e.g. as fertilizer.
To feed the plants, the crop is grown in “vegetative” forms (like cucurbits and potatoes) on the plants’ leaves. In this state, it is easy to measure the amount of energy that is released into the atmosphere.
The intensity of plants on light and water is more than what we can get from a regular light. Plants in the vegetative stage require 20% the amount of water that the plants on the light can use. They grow much faster than the light-dependent plants and need much more energy. So this is in the range of 30-50% more energy than in the light-dependent plants.
To feed the plant, it is growing in a “cultivated” form.
There are some plants other than cucurbits and potatoes whose photosynthesis process uses their own water and sun to power the photosynthesis.
The photosynthesis process of these plants are quite different.
They are called “phytoplankton” (they are about 7-18 mm across) because they are plants themselves.
They have to use the full amount of solar energy they receive for the photosynthesis process. This means they require about 3-5 times the amount of water water can hold. They do grow on land, but they can grow in rivers and lakes.
For this reason, they use all the water available for them as fertilizer.
The photosynthesis process of a chlorophyte (like most plants) also uses the entire surface of the plants as photoperiod. It is called the “green” part of the photosynthesis process.
So that is why you see plants of a certain size grown in a certain area. But these plants have to use even more water.
In the case of potatoes, the energy that the tuber’s photosynthesis uses makes up 20% of what it can use. Because of the large amounts of energy required, and of the need for soil moisture, most of the energy (20% of total input) is lost as heat.
The final percentage of energy needed is:
30% for plants in the vegetative stage
50% for plants in the vegetative stage with
