Protected farming is a method by which the natural environment is manipulated and controlled to enhance plant growth. This is one of the best methods of increasing crop production, which is both safe and sustainable. Protected farming or greenhouse farming is a part of hi-tech agricultural development. If a minimum of 3 greenhouses are build in a specific area, the whole state and subsequently, the whole nation will start producing a higher yield.
The greenhouses will also ensure that our younger generations stay strong and focused in the field of farming. We can provide high quality care to the plants this way. Greenhouses promise a high yield every year.
Rain culture technology, hydroponics, fertigation are all the latest developments in protected farming. The use of high yielding genetically modified seeds, controlling sunlight, the length of days and nights and the quantity of carbon dioxide in the atmosphere are all important features of protected farming.
Increasing the harvest during monsoon can prevent the subsequent price rise of vegetables. The advantage of greenhouses are that you can cultivate crops inside the structure without concern for the weather conditions outside. What you need for this is good quality greenhouses. The inside of the greenhouse should be spacious enough for farmers to work in comfortably. You can physically control the atmosphere in which the plants grow. Polythene sheets are a good choice for making greenhouses, but fibreglass and glass are also excellent choices. They are also known as mist house, poly house and shade house.
High capital investment is the one factor discouraging many from following this trend. But now, the help provided by the state horticulture mission has provided a solution to this problem. In spite of this, financially backward farmers can opt for the rain shelter program.
Protected farming is a method that deserves to be promoted. Providing more subsidies will definitely help propagate the movement.
Greenhouses make effect use of the available sunlight while filtering out the harmful UV radiation at the same time. Since the density of carbon dioxide is increased inside the greenhouse, the growth of plants are commendably better. The walls of the greenhouse also prevent pests and insects from harming the plants.
The outside weather variations including rain, blizzards, snow, wind or sunlight does not effect the growth of plants inside the greenhouse. This means, any crop can be grown inside the greenhouse irrespective of the season. But the temperature increase inside the greenhouse during summer is a bit of a problem. So effective ventilation and air conditioning methods should be in place. The greenhouse should be rectangular in shape.
High quality GA pipes should be used for the construction of greenhouses. Although any crops can be cultivated inside the greenhouse, capsicum, tomatoes, salad cucumber, beans are flowering.
