What is Polyhouse?

Polyhouse farming is a new and widely accepted method of farming in present days. However, there are many doubts asked by farmers regarding Polyhouse and its benefits. The Polyhouse is a tunnel used with polyethylene in semicircular shape. Polyethylene sheets stabilize the ultraviolet rays and helps in proper photosynthesis in crops. We can make it in other shapes also but the semicircular shape is most commonly adopted shape in Polyhouse. Mostly it is constructed in east to west direction to allow proper entry of sunlight. I have been introduced to Polyhouse by my uncle who set a Polyhouse in his field and I was very confused about its productivity. But my doubts got clarified when I saw the crops harvested from his Polyhouse. It was large in amount and best in quality. The colour of the crops also was not faded and it was very attractive.

Importance and advantages of Polyhouse farming:

In Polyhouse farming, we can protect our crops from any adverse environment such as high humidity or high temperature. There is a facility in Polyhouse to control temperature or humidity. There will be an increase in the production of vegetables, fruits or flowers in Polyhouse farming without losing their color and quality. Polyhouse can protect the crops by preventing the entry of animals and birds into the farm. When we cultivate in normal farm, nearly 1/3rd of the crops may be lost due to the attack of insects and worms, whereas in Polyhouse farming, we can harvest the crops about 3 to 5 times more without much damage or loss. We can farm any crop in Polyhouse regardless of season or place which grows like tulips, strawberries, alpines etc. One of the main reasons for the decrease in agriculture in India now-a-days is non availability of enough agricultural lands. But the invention of Polyhouse is a solution for lack of agricultural lands. We can get more crops from less space in Polyhouse farming. The Polyhouse is made in such a way that it can provide water and fertilizers in required amounts in a controlled manner which can result in high yields.

Types of Polyhouse:

Depending on the control system using Polyhouse can be with semi automatic control system or with fully automatic control system. In semi automatic control system, manual adjustments are needed to maintain the Polyhouse in good condition whereas in automatic system, pre-settings are enough for the maintenance of Polyhouse. Proper alertness and technical skills should be needed while managing semi automatic Polyhouse. Any deviation from this may result in damage of crop and may lead to loss. In an automatic system of Polyhouse less attention is enough for maintenance, but it is very costlier compared to semi automatic type.

Cost to set a Polyhouse:

To set a Polyhouse it costs around Rs.750 to Rs.1000 per square meter. The range of cost depends on some factors like quality of the material, place, size, shape and structure. We can use bamboo, metal pipes, wood etc., as supporting material. The steel and other metal pipes have longer durability compared to other materials. Though it is costly to set and maintain a Polyhouse, we can get the profit in large scale if we use it in a proper way. Government is encouraging Polyhouse farming by giving 25 to 50% of subsidy to set up a Polyhouse.
