BACKGROUND OF THE INVENTION
[002] As per the data published in the Food and agriculture organization of the United
Nations(http://www.fao.org/faostat/en/#data/EL/visualize,http://www.fao.org/faostat/
en/#data/QV), agriculture is being practiced on more than one-third of the Earth’s land.
The total net production value is around 2.6×109
10 USD. The agriculture sector is of
paramount importance in providing jobs to millions of people around the globe. Apart
from the sustainability provided by the agriculture sector, it also provides many
methods to improve human well-being. Therefore, research is continuously required
for improving agricultural methods and related technology with the help of increasing
15 human knowledge. The integrated approach has been practiced by scientists, breeders,
and policymakers around the globe to provide effective measures to sustain the
agricultural domain. One of the objectives is to increase the agricultural yield that
would ultimately feed millions of people around the globe.
[003] In an effort to eradicate the ugly spot of hunger from the face of the humanity,
20 there is an evident need to significantly increase the production and supply of food by
integrating different elements and strengthening the plant breeding tools for crop
improvements (Beddington et al. (2012). The role for scientists in tackling food
insecurity and climate change. Agric. Food Sec. 1, 10). In pursuit of providing an
increased yield, one of the areas which have shown potential success is the treatment
2
of seed material to show increased resistance to pathogens and enhance survivability.
Seed coating is becoming a popular method of improving the quality, plantability and
ease of handling of seeds, ultimately leading to more efficient farming and improved
yields. Further, it also has reduced major risks compared to other farming practices as
5 it includes direct application of plant protection products on seeds per se, which
eliminates the chances of direct human contact to harsh antimicrobials or insecticides.
Such methods also dramatically reduce dusting-off of plant protection substances to
the environmental surroundings, thereby leading to healthy and effective farming
practices. However, the conventionally available methods for the coating of seeds are
10 generally based on harsh chemical compounds which may either be toxic or nonbiodegradable. The repeated use of synthetic chemical compounds like synthetic
insecticides in the seed coating compositions also elevates the chances of resistance
development in the insects or other target strains.
[004] US20110105333A1 relates to seed treatment compositions comprising active
15 ingredient and hyperbranched polymer, wherein the hyperbranched polymer is used as
a binder to promote adhesion of the active ingredient(s) to the seeds. The application
also relates to methods of treating seed with the said composition.
[005] US4251952A relates to coated plant seed comprising a seed having
a coating thereon comprising of polymeric material in direct contact with the normally
20 exposed seed surface; the improvement comprising employing as such coating an
intimate mixture of sugar and water insoluble polymeric material. The application
further relates to the coating of plant seeds, including compositions and method
therefor.
3
[006] EP2308297A1 relates to an agrochemical composition suitable for seed
treatment comprising herbicide and an adhesive polymer, and method of application
thereof.
[007] Despite of the ongoing extensive research in the present field of art to come up
5 with an effective, harmless and affordable seed coating composition, there still lies a
major gap between the conventionally available seed coat compositions and an ideal
composition which may be help in advancing the aspects including germination,
seedling vigour, nutrient uptake, and growth of the plant developing from the coated
seed. Therefore, there exists a dire need in the present field of art demanding more
10 focused research for the development of non-toxic, economical, and effective seed coat
composition.

[0037] As discussed in the background of the present disclosure, seed treatment or seed
coating is becoming one of the most viable alternatives to the traditional broadcast

coating compositions poses higher risk of development of side effects to both humans
and the environmental conditions. Many of the conventional seed coating methods
include the use of non-biodegradable synthetic compounds which directly or indirectly

need for an effective, safe and biodegradable seed coating composition, the present
disclosure discloses a biosticker composition comprising: (a) at least one polymer
having a weight percentage in a range of 1-10% with respect to the composition; (b) at

seed material, and alongside, the microbial culture provides necessary microbial
presence around the coated seed for the nutritional benefits and optimal growth. Unlike
15 the conventional methods which may only provide protection from disease causing
organisms to the seeds, the biaocoat composition as disclosed herein additionally
provides enhanced germination percentage, nutrient uptake, seedling vigour, growth
and lowered damping off in coated seeds on comparison to non-coated seeds, thereby
exhibiting synergistic effect as compared to the non-coated seeds.
