Natural fertilizer - Plant growth promoter and regulator

Super Power Gold

Growth promoter is a natural/herbal fertilizer, especially designed for the overall growth of the plants. These growth promoters are intended to accelerate the rate of growth and maturation of crops or plants, without disturbing their natural physiological actions. These premium quality plant growth promoters increase the yield as well as control the pests & pathogens. A highly effective and safe biological tonics, these growth promoters boost an all round development of the crops by regulating their metabolic activities from root to the leaves. The product is available in different packaging specifications, which can be tailored to specific needs. This is the best natural fertiliser for plants and gardens and flowers. crop booster, plant booster, growth booster fertiliser

Plant Growth Promoters and Regulators

Plant growth often occurs under a range of stressful conditions, including soil acidity and alkalinity. Hydrogen ion concentration, which determines pH of the soil, regulates the entire chemistry of plant nutrient colloidal solutions. Beyond certain levels of pH, multiple stresses such as hydrogen ion toxicity, and nutrient imbalance, toxicities and deficiencies are induced in plants. Breeding for stress coupled with suitable agronomic practices has been a way to deal with this situation in agriculture. However, plant growth promoting microbes (PGPM) have shown potential as sustainable plant growth enhancers and have potential to help with a range of stresses in their environment. Considering the long-term evolutionary relationships between plants and microbes, it is probably that much remains unknown about potential benefits of microbes that could be harnessed from PGPM.

This article reviews the current understanding of acidity and alkalinity stress effects on plants and various approaches have or could address these stresses. This review provides a detailed account of the current understanding regarding the role of PGPM in acidity and alkalinity stress management, including when agronomic practices and plant breeding are combined. Approaches already evaluated have shown limitations because acidity and alkalinity in soils are gradual and progressive conditions. Greater exploitation of PGPM in this regard, would be interesting to explore as they have the potential to address multiple stresses in a more sustainable fashion. Future crop production will require further breeding for pH stress resistance, but also implementation of microbial technologies that provide enhanced tolerance to pH stress.

Plant growth regulators are the chemical substances which govern all the factors of development and growth within plants. Some other names used to refer to it are phytohormones and plant growth hormones.

Phytohormones are organic compounds which are either synthesized in laboratories or produced naturally within the plants.  They profoundly control and modify the physiological processes like the growth, development, and movement of plants.

Based on their actions, plant growth regulators are broadly classified into two major groups:

  • Plant growth promoters
  • Plant growth inhibitors.


Auxins, Gibberellins, and Cytokinins are grouped into Plant growth promoters while Abscisic acid and Ethylene are grouped into Plant growth inhibitors.

Ethylene can be grouped either into the promoters or into the plant inhibitors.

Let us have a detailed look on the plant growth and development before studying plant hormones or plant growth regulators.

Characteristics of Plant Growth Regulators

As the plants require oxygen, water, sunlight, and nutrition to develop and grow, they do require certain chemical substances to manage their growth and development. These chemical substances are known as Plant Growth Regulators and are naturally produced by the plants itself.

These are simple organic molecules having several chemical compositions. They are also described as phytohormones, plant growth substances, or plant growth hormones.

They can accelerate as well as retard the rate of growth in plants.

Plants growth hormones or plant growth regulators exhibit the following characteristics:

  1. Differentiation and elongation of cells.
  2. Formation of leaves, flowers, and stems.
  3. Wilting of leaves.
  4. Ripening of fruit.
  5. Seed dormancy, etc.


Generally, there are five types of plant hormones, namely, auxin, gibberellins (GAs), cytokinins, abscisic acid (ABA) and ethylene. In addition to these, there are more derivative compounds, both natural and synthetic, which also act as plant growth regulators.


  • Improve absorption through the roots
  • Increase crop resistance to adverse condition ( drought, frost, salinity, hail, disease)
  • Improve flavor, color, firmness and preservation of fruit
  • Help the plant to produce its own protein easier, saving energy required to produce amino acids to benefit formation of the proteins and plant cells.
  • Improve the soil structure, promote fertilizer efficiency.
  • Increase capacities of water holding and cation exchange.  
  • Prevent soil from contamination of heavy metallic ions, reduce pesticide residue.
  • Enhance soil ability of Anti-hard water.
  • Stimulate plants growth and seed germination.
  • Promote root development.
  • Improve nutrient uptake through the leaves and roots.
  • Improve the effectiveness of pesticides.
  • Increase yield and improves quality of plants.
