Polyhouse Agriculture

What is Polyhouse Agriculture?

Polyhouse agriculture is the cultivation of crops under complete control of environmental conditions like temperature, humidity with an automated system. Every crop has a specific set of climatic conditions in which it is cultivated. Therefore, the crops are divided based on climatic constraints. But, keeping note of today’s unseasonal climatic occurrences, growing crops under a stabilized condition is becoming harder. Polyhouse Agriculture is used to treat the crops under a stabilized and controlled temperature, humidity, and climate of the crop’s surroundings.

Benefits of Polyhouse Agriculture

As the climate and the environmental constraints are reduced in the case of a polyhouse Cultivation, crops can be grown at any time or any point of the year without any fear of damage. 

Vegetables and flowers, which are mostly grown in Polyhouse give a good yield and it was found that there were a smaller number of instances where the plant was subjected to a transplant shock, which happens due to the uneven condition of the environment.

Transplanting becomes less risky when it is done under a greenhouse/ polyhouse and all the plants will grow uniformly.

It happens that the UV rays, excessive rains, and frost cause degradation of the crop by any means. UV rays deteriorate the plant’s ability to photosynthesize and cause reduced stomatal-conductance, Leaf area and wholly decrease the rate of maturation and yield.

Polyhouse Cultivation and Irrigation System

In the  Polyhouse cultivation, the natural light is blocked by the usage of the cover with a UV filter and shade nets. This helps in the obstruction of excessive light which can minimize the yield. These also help in shading the crops from frosting on them and the water supply can be controlled.

The Irrigation used in the Polyhouse is mostly drip or sprinkler techniques. The former the transport the water directly to the roots and the latter sprays the water onto the plants/crops uniformly. 

As every condition of the crop is controlled, the fertilization becomes very easy and there is very little chance of pests as the crops are mostly in an isolated condition.

Types of polyhouse

The construction and the scale of polyhouse depend upon the scale of the crops and the cost type one wants to invest in and can be differentiated as

  1. Naturally Ventilated Polyhouse: It is an easy option for those who cannot invest more into the polyhouse. The crops can grow without having any heavy climatic constraints. It may have a UV Filter but may not have other Control options. Which are used in controlling the other environmental factors. These generally fall under low-cost polyhouses.
  2. A climate-controlled polyhouse: It is an extension of the previous type. It costs more than the former, but its foundation is structured better than the naturally ventilated polyhouse. This is a thermal control system and it is equipped with a pad and fan system in some cases and an automatic control system in the high-end polyhouse. These are used for the crops which grow for a long time. These polyhouses use passive ventilation to provide highly strained light.

Return on Investment with Polyhouse agriculture

Profit-making is the most important aspect of the farming industry. Many farmers sell their crops at a very marginal profit or sometimes even at a deficit rate. Even though the quality of the product isn’t the whole, if the crop is harvested to its full potential, a farmer can profit off from his crop. Polyhouse construction can take a lot of investment but has the potential to surely pay off in multiples by the end. Farmers can grow the most demanded crop irrespective of the year and harvest it and sell it whenever a farmer wants. This helps them bring a greater annual profit and a polyhouse has already helped many farmers in the country with seeing profits while it can help many more in the long run. It is possible with the help of the best polyhouse manufacturers.

Difference between Greenhouse and Polyhouse Agriculture

The basic appearance of the polyhouse model is similar to Greenhouse where HDPE net/cover is used to cover the crops from the outside environment and let them isolate in controlled surroundings. The cover is supported by an extensive foundation made of Galvanized Iron pipers, curtaining the whole area. The screened filters help stop the UV rays from falling on the crops which could potentially damage them. Even though Polyhouse is a category of a greenhouse, it is a smaller or a miniature version of a greenhouse that is used for small-scale commercial crops. Polyhouse needs skilled labor, who are familiar with controlling the whole system. Many farmers in India don’t have the necessary skilled labor. But, with the ongoing trends, many farmers are switching to the modern age farming techniques where the cropping is done using advanced techniques and well-equipped machines.
