, Description:Field of the invention:

The present invention relates in general to a plant growth regulator which affects the growth characteristics of the plants including crops.

Particularly, the present invention relates to synergistic compositions of plant growth promoter which enhances the growth of the plants including crops simultaneously increasing the yield.

Background of the invention:

In the last few years, Indian agricultural sector is facing lot of problems including but not limited to unexpected climatic conditions as well as various infestations. India stands at the second position in the world after China in global vegetable production. The various important crops are cereals, oilseeds, pulses, vegetables and fruits. Major vegetable crops grown in the country are tomato, onion, brinjal, cabbage, cauliflower, okra and peas. Today, health of the crops is one of the important issues which farmers face most often.

Plant growth regulators play vital role in modifying / improvising the health of the crops. The plant growth regulators are organic compounds other than nutrients that affect the physiological processes of growth and development in plants when applied in low to very low concentrations. These as either natural or synthetic compounds that are applied directly to a target plant to alter its life processes or to its structure to improve quality, increase yield, or facilitate harvesting.

The natural plant growth regulators are produced by the higher plants themselves. These regulators control the growth or other physiological functions at a site that is remote from its place of production. Some examples of the naturally occurring plant growth regulators include auxins, gibberellins, cytokinins, ethylene, tri ocantanol, growth retardants and growth inhibitors. Among these regulators, auxins were first discovered in plants followed by gibberellins and cytokinins.

Presently, the farmers are using the plant growth regulator to control the physiological processes in the crop production, including flowering and fruiting, partitioning of assimilate, germination, growth suppression, and post harvest ripening.

Plant growth regulators like promoters, inhibitors or retardants play a vital role in controlling internal mechanisms of plant by interacting with key metabolic processes such as nucleic acid metabolism and protein synthesis. Thus, use of the plant growth promoters is globally recognised as an important tool to increase the crop production or yield. In view of this, the research and development is focussed to develop synthetic growth promoters similar to auxins, gibberellins, cytokinins and the likes.

Normally, the auxins are responsible for phototropism and apical dominance in growing plants. They also influence abscission of blooms, leaves, and fruits, making them valuable tools in bringing fruits and horticultural products to market. Auxins are widely used in plant propagation and tissue culture. In tissue culture, auxins are balanced with cytokinins for full morphogenesis. Typical examples of natural auxins are 3-indoleacetic acid (IAA) and its salt, indole-3-butyric acid (IBA), phenyl acetic acid while that of synthetic auxins are 1-naphthaleneacetic acid (NAA) and 2-4-dichloro phenoxy acetic acid (2,4-D).

Phenyl acetic acid and its sodium salt are natural auxins and are available in more abundance in nature. It has been found to be an active auxin present predominantly in fruits (Ref. Wightman, F.; Lighty, D. L. (1982). "Identification of phenyl acetic acid as a natural auxin in the shoots of higher plants". Physiologia Plantarum. 55 (1): 17–24). Phenyl acetic acid is available plentiful as a natural auxin. However, it is much weaker than IAA which is the basic auxin molecule. Phenyl acetic acid as well as its sodium salt are weak auxins.

Synthetic auxins are potent and less expensive alternatives to IAA. 2,4-D is very often the auxin of choice in inducing callus and in keeping cells in the dedifferentiated state.

Research has been always carried out to develop new plant growth promoter, which can efficiently increase weight and size of the fruits or seeds, accelerate their harvestability, growth of the crops, increases yield to meet the demand of food grains as well as vegetables due to increase in population, climatic change, soil degradation, etc.

We have attempted to develop the composition comprising the active component selected from substituted phenyl acetic acid; 2-[2-(2,6-dichloroanilino)phenyl]acetic acid; 2-(4-(2-methylpropyl)phenyl)propanoic acid; 2-(6-methoxynaphthalen-2-yl)propanoic acid and /or their salts to synergistically increase its performance as plant growth promoter for the crops like cereals, oilseeds, pulses, vegetables and fruits, particularly vegetable crops such as tomato, onion, brinjal, cabbage, cauliflower, okra, peas, cucumber, capsicum, turmeric, and the likes.

We have carried out the prior art search and have not come across any document which shows / teaches / demonstrates the synergistic compositions of the plant growth promoter comprising phenyl acetic acid; 2-[2-(2,6-dichloroanilino) phenyl]acetic acid; 2-(4-(2-methylpropyl)phenyl)propanoic acid; 2-(6-methoxynaphthalen-2-yl)propanoic acid and / or their salts.

It was also found that yield of the tomatoes, brinjals, capsicums, cucumbers, turmeric, radish, grapes, pomegranate and the likes increased as well. These periods vary from the crop to crop. Since the weight of the fruits is proportional to cube of diameter, this translates to 30 to 70% increase by weight. The number of fruits on the plant also increased by up to 30%.
The synergistic compositions of the present invention are non-toxic and inexpensive. It is observed that they are effectively exhibiting the synergistic properties by increasing the size and weight of the fruits/ seeds as well as increasing the yield of the crops. They do not exhibit adverse effects on the crops. Further, the compositions do not harm the users including the farmers unlike fertilizers. Their use will not deteriorate the quality of the crops as well as that of the soil.
The present invention can be illustrated with the below mentioned examples and comparative examples but not by way of limitations. In other words, exemplary illustrations of the operation of the present invention, the practice of its formulation and rendering of the disclosed process are described in the following examples. In addition to the preferred modes of operation, a practitioner of sufficient skill in the art will appreciate that the meets and bounds of the present invention are not limited by the specific instances described herein, rather are defined by the equivalents provided by the claims of the present invention.

The homogeneous compositions according to examples 1 to 7 were prepared by thorough mixing of all the components in water as illustrated in Table 1.

These formulations were diluted to 0.2 to 0.3 % in water and were used to study the efficacy of the compositions according to examples 1 to 7. The control was without any use of the compositions. The bioassay method used to study efficacy of the compositions vis-a-vis control was studied by Spray Method.

Spray Method:

In spray method, the application of the compositions was monitored for change in the size and weight of the brinjals, tomatoes, turmeric, radish and grapes i.e. growth. The field trial was laid out in Randomized Block Design (RBD) with three replications and sixteen treatments including untreated control. The compositions according to the examples 1 to 7 were evenly sprayed on the crops twice with one week interval. The first spray was applied at the stage of flowering. The size of the five randomly tagged brinjals, five randomly tagged tomatoes, five randomly sized turmeric, five randomly tagged radish and five randomly tagged grapes were measured by Vernier Callipers on 17th day from the day of flowering. The weight of the five randomly tagged brinjals, five randomly tagged tomatoes, five randomly sized turmeric, five randomly tagged radish and five randomly tagged grapes were also measured by weighing scale on 17th day. The yield was measured as well. Observations were noted about the size and weight of the brinjals, tomatoes, turmeric, radish and grapes as well as the yield.
The observations regarding the size and weight of the brinjals, tomatoes, turmeric, radish and grapes as well as yield are illustrated in the Tables 2, 3, 4, 5, and 6 respectively.
