Phosphorus is a chemical element with the symbol P and atomic number 15. Phosphorus is a vital component in reviving the energy of a plant, especially during the photosynthesis process. Phosphorus brings vigor to all plants. Generally, it helps convert other nutrients within the plant and helps in the growth of the plant.
If the plants are not growing, or the flowers are little are non at all with weak root systems, it shows that the plant lacks phosphorus.
Phosphorus in minerals is called phosphates from the earth. Phosphorus can also be found, in the human body.
The main function of phosphorus in a human body is in the formation of bones and teeth, as the body needs phosphorus to make protein for the development and growth of the body, for maintenance and in repairing cells and tissues in a human body.
Some of the food that is rich with phosphorus includes eggs, cottage cheese, milk, hard cheese, sunflower seeds, chicken, pumpkin seeds, and canned sardines in oil.
White phosphorus is used in some explosives, including rockets and poison for rats. The red phosphorus is used in safety matches, tracer bullets, incendiary devices, pesticides, pyrotechnic devices, and fireworks
Nitrogen is a significant component of chlorophyll. Chlorophyll is the compound where plants use sunlight energy to produce sugar out of water and carbon dioxide. The process is called photosynthesis. A good source of nitrogen for plants can be from fertilizer, planting green manure crops such as peas or beans around your plant, or adding coffee grounds to the soil.Plants do not get nitrogen from the air but the soil. Various microorganisms convert ammonia to other types of nitrogen compounds that are simple for plants to use. In other words, plants can get their nitrogen indirectly from the air but via microorganisms in the soil and via the plants’ roots.
Typically the earth atmosphere has 78% nitrogen gas or N2. Though there is nitrogen in the air, not much can be found in the earth’s crust. Some of the rare minerals that have nitrogen are the saltpeter, small living organisms on earth, plants, and animals.
Some of the found use of nitrogen other than agro is in the chemical industry such as nylon, nitric acid, dyes, medicines, and explosives.
Fertilizers are chemical elements supplied to crops to increase their productivity. Typically fertilizers contain nitrogen, potassium, and phosphorus. Fertilizers enhance the retention capacity of the soil and increase its fertility.
The general definition of NPK are as listed:
- Nitrogen – The leaf maker. Symbol as N
- Phosphorus – The root maker/flower inducer. Symbol as P
- Potassium – The flower inducer/fruit maker. Symbol as K
The fertilizer bag is labeled to represent the NPK rate it carries.
What are Hybrid Plants?
A hybrid means a mixture of two or more elements. Hybrid plants mean cross-pollinating plants from different varieties to produce seed and then growing the seed. The plant that results from the seed is known as the hybrid plant.
One of the main reasons why the hybridization of plants is practiced is for commercial use. Hybrid plants can be more disease resistant, have bigger or smaller flowers, tastier fruits or even nicer smelling flowers. The hybridization is done based on the commercial needs of the said plant.
How are Plants Hybridized?
The basis of hybridization is that pollen from a different variety of plants has to be used to pollinate a plant from another variety. As the first step, the stamen (male part of the flower) has to be removed from the plant that is to be pollinated. This is crucial to avoid self-pollination. Next, the pollen from another variety of plant is transferred manually to the pistil (female part of the flower) for pollination to occur.
If the pollination is successful, the fruit formed from the flower will be kept for further plantation to review the result. The plant that grows from the seed is the hybrid plant. If the results meet expectations, the hybridization will be repeated and more seeds will be produced and replanted.
Examples of Hybrid Plants
Some examples of hybrid plants include:
- Tangelo: cross between grapefruit and orange
- Plumcot: cross between plum and apricot
