Benefits of technology

The present invention is about developing a plant growth stimulator that can promote and maintain plant growth. The stimulator is made from a nutrient medium containing black tea and a carbohydrate source, and includes specific microorganisms like Acetobacter xylinum, Candida sp. and Zygosaccharomyces rouxii. The invention also provides a process for preparing the plant growth stimulator and a method for using it to promote and maintain plant growth, even in the face of multiple diseases.

Problems solved by technology

In agriculture / horticulture many chemical materials used for improving plant health and productivity, are proving after many years, to have undesirable side effects.
Leaving toxic chemical residues on vegetables, fruits or in soil are reported to be toxic to soil and to human health.
Many man-made materials do not biodegrade and are proving dangerous to the environment by increasing soil and water pollution.
However, plants take a long time to grow and produce the herbal material for commercial use.
As it is, there is very limited land available for providing food security to increasing population.

Effect test

example 1

[0071] The nutrient medium was prepared by adding 2.5% w / v cane sugar and 0-1.5% w / v of black tea powder, to boiling tap water and immediately removing from the gas-stove, covering with lid and allowing to cool to room temperature, filtering through a muslin cloth, inoculating with fungus and culturing it away from the sun-light or heat. The maximum sugar concentration required for growth of the fungus was 2.5%. In the absence of sugar, color of the medium did not turn to golden yellow or impart acidic smell. Under the sugar stress, the fungus synthesized red color pigment and fermented tea did not show increase in plant productivity, when sprayed on plants.

example 2

[0072] The nutrient medium was prepared by adding black tea powder of any brand in 0.5% w / v concentration. In the absence of black tea, the fermented medium did not show antimicrobial activity and increase in plant productivity. Concentration of tea was not found to be very critical. Minimum tea concentration of 0.5% w / v was found to be adequate to get golden color liquid with acidic smell.

example 3

[0073] The nutrient medium was inoculated with “Tea fungus” and incubated for 8 days. Sugar utilization was complete within 48 hours. However, the fermented material did not show improvement in plant productivity in turns of flowers or fruits. The optimum incubation period was found to be 6 days. (This was found to be inoculum dependent).

[0074] The majority of plants revealed good results with 1:100 dilution. Some varieties of rose, and mango required 1:50 proportion. The fermented tea was filtered through muslin cloth and stored for 8-90 days before application.

[0075] The material remained active up to 90 days.
