A COMPOSITION FOR HORTICULTURE FIELD

The present disclosure relates to a composition for horticulture.

DEFINITIONS:

As used in the present disclosure, the following terms are generally intended to have the meaning as set forth below, except to the extent that the context in which it is used indicates otherwise.

Horticulture: The term“Horticulture” refers to the branch of agriculture dealing with the art, science, technology, and business of growing plants. It includes the cultivation of medicinal plants, fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants. These plants are grown in a common private gardening environment or in nurseries. The difference between these plants and plants in agriculture is that the need of individual plant is taken care off. Wherein in agriculture the mass need of one crop variety is attended to without use of soil or little soil.

Hydroponics: The term“Hydroponics” refers to the branch of hydroculture, which is a method of growing plants without use of soil by using solutions containing minerals and nutrients in a water.

Aeroponics: The term“Aeroponics” refers to the process for growing plants in an air or moist environment without the use of soil or an aggregate medium. Sometimes it is termed as hydroponics as it uses water for transmitting nutrients. Potting Mixture: is a medium to grow plants, herbs and vegetables in a pot or other durable container. Potting mixture is also referred to as a growing medium.

Coco peat: is a multi-purpose growing medium made out of coconut husk. The fibrous coconut husk is pre-washed, machine dried, sieved and made free from sand and other contaminations such as animal and plant residue.

Peat: is an accumulation of partially decayed vegetation or organic matter.

Moss: taxonomic division Bryophyta are small, non-vascular flowerless plants that typically form dense green clumps or mats, often in damp or shady locations.

Manure: is an organic matter that is used as organic fertilizer in agriculture. Most manure consists of animal feces, other sources include compost and green manure.

Gravel: is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments.

Composted bark: contains very little in the way of nutrients but is a good long-lasting mulch which will help to retain moisture and keep weeds down.

Perlite: is the name of a naturally occurring mineral. In nature, it exists as a type of volcanic glass, created when the volcanic obsidian glass gets saturated with water over a long time.

Vermiculite: is a type of naturally occurring mineral that expands into long, worm-like strands when heat is applied through a process called exfoliation. When in its expanded form, the material has a low density and thermal conductivity.

Vermicompost: is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. Verm i cast is the end-product of the breakdown of organic matter by earthworms. BACKGROUND

The background information herein below relates to the present disclosure but is not necessarily prior art.

All special plants producing fruits, flowers and vegetables cannot grow successfully in all types of environmental conditions and soil. They differ in their tolerance of adaptation to the conditions. Such plants can be cultivated in a controlled environment suitable for their growth using different techniques such as horticulture, hydroponics and aeroponics. These techniques use optimized sensitive cultivation conditions for plants suitable for their growth. The cultivation conditions can include external factors such as environment, insects, pests and diseases as well as nutrition and internal factors are such as factors associated with plant such as sex distribution, heterostyle, dichogamy, aborted organs, non-viable pollen, genetic incompatibility and nutritive conditions. Plants cultivated through horticulture, hydroponics and aeroponics also suffer from common issues such as nutrient deficiency, algae growth, pests and pathogens. For growth of plants, the nutrients play important role in the cultivation techniques.

A number of commercial compositions for horticulture for improving nutrient contents and promote growth of plant through cultivation of plants using these techniques are available in the market. However, these compositions have limited activity and effectivity.

Therefore, there is felt a need for a composition for horticulture that mitigates the aforestated drawbacks.

OBJECTS

Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows: An object of the present disclosure is to ameliorate one or more problems of the prior art or to at least provide a useful alternative.

Another object of the present disclosure is to provide a composition for horticulture.

Still another object of the present disclosure is to provide a composition capable of promoting plant growth and improving product characteristics in horticulture.

Yet another object of the present disclosure is to provide a composition capable of promoting plant growth in hydroponics and aeroponics.

Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure. SUMMARY

Experiment 7: Composition for horticulture/hvdroponics (Orchids^') in accordance to the present disclosure: Experiment 7 was carried out in a similar manner as that of experiment 1, except no sorbitan monooleate was used, Orchid flower plant was used instead of Rose, and the potting mixture consisted of equal quantities of charcoal, and waste of coconut bark as shown in figure 5. The composition used in experiment 7 was having 60 wt.% of the potting mixture, 30 wt.% of the additive, and 10 wt% of the mixture of plant growth regulator. Three variety of forty days healthy and uniform tissue cultured Orchid plants which had white, light Purple and dark purple shade were procured from Thailand, as shown in figure 3, and used for this experiment. The experiment 7 was conducted in net house of Orchid flower as shown in figure 4, at Kudadra village near Hansot.

Shade net house was covered with green plastics net. It was used for growing Orchid plants provided that partially controlled atmosphere and environment was maintained by reducing light intensity and providing effective heat during the daytime to the orchid crop. Growing medium for Orchid was kept moist but never be soggy.

During this experiment, the composition of 75% additive and 25% plant growth regulator and recommended dose of fertilizer (RDF) 0.2 % of NPK (20:10:10) was were administered at fortnightly intervals. 1.25 ml/Liter of the composition for plant growth in hydroponic in accordance with the present disclosure was administered per every 15 days. The quantity of water required for fertigation was roughly about quarter liter per plant and it was applied by sprinkler. The irrigation was done twice a day for the plants during hot months and once a day during cool months, besides water was also sprinkled once a day to the floor for maintaining the temperature and humidity inside the greenhouse. As shown in figure 6, growth parameters were recorded viz., plant height, leaf length, leaf width, root length of randomly selected plants of different treatments and were recorded at 30, 60, 90 and 120 days after planting (DAP). The results after the treatment are shown below in table 3. Table 2: Periodic analysis of the growth of the plants during experiment 7:

*DAP: Days After Planting

Table 2 shows that, the plant growth was better when the composition for the plant growth in hydroponics in accordance with the present disclosure was administered along with the recommended dose of fertilizer. When the flower harvesting was carried out after start of the experiment 7, the number of flowers were increase by about 12% compared to the previous harvesting and then the number of flowers at the time of average harvest counting was increased to about 23.91% after four months. The figure 5 demonstrates that the plant height, leaf length & width, root growth of the plant was significantly enhanced over previous harvest. As demonstrated in figure 7, the quality of the flowers was also enhanced after treatment with the composition for plant growth in accordance with the present disclosure.
