Greenhouse Effect is a pretty well heard term on the news,
but do you know the origination of the term?
The concept of a greenhouse dates back to the Roman times, with the
first Greenhouse built in the 13th Century, then known as “giardini botanici
“to preserve exotic plants that the explorers brought back from the tropics.
The concept is simple; a structure where the walls and roof
are made of transparent materials. Sun rays pass through the transparent walls
and roof warming up the air and contents inside the greenhouse which on getting
warmer re-emit the heat but this re-radiated heat from them cannot pass through
glass again since they are of a longer wavelength, hence the temperature inside
rises.
The need to protect the crops against unfavorable natural
conditions prompted the advancement of protective cultivation. Greenhouses have
got the extravagant of farmers, with their yields being safe from the evil
impacts of climate, for example, untimely rain, hail, temperature fluctuations,
etc. Under the National Horticulture Mission, farmers are being given subsidies
to use greenhouses. Greenhouse development has turned into an essential
approach of Indian Agriculture. Progressive farmers have achieved manifold
increase in their yield and income by switching over to unconventional
agricultural techniques like organic and poly house farming. A greenhouse set up on one acre costs about
36 lakhs, out of which 65 per cent is granted as subsidy by Horticulture
Department of Central and State Governments and a farmer has to bear an
expenditure of about 12 lakhs.
The total production of vegetables in India is next to China,
but per capita availability of vegetables is much lower than required,
therefore, it is utmost necessary to improve the productivity of crops including
vegetables. Steaming is just a fleeting solution; it loses its effectiveness
every year. Pests and pathogens recuperate more rapidly every time. Steaming
results in exhaustion, the increasing costs of fossil fuel, and the effects on
the environment make it necessary to find a different approach. Steaming

With all the other climatic issues secured, the only door left
to close is the one belonging to pests and pathogens, where Silver Hydrogen
Peroxide emerges as the most effective gate keeper. Due to intensive soil
management practices, soils in greenhouses are exhausted and very conducive to
soil borne pathogens. The most prominent
fungal pathogens are Sclerotinia sp., Rhizoctonia solani, Botrytis cinerea and
Pythium sp. The first three are able to produce sclerotia, by which they can
survive in soil for many years requiring their timely disinfection. Effective beforehand
soil disinfection with Silver Hydrogen Peroxide proves advantageous in many
ways. Initial soil fumigation with silver hydrogen peroxide before plantation,
moreover treatment by drip method is more effective in greenhouses.
