Polyhouse Subsidy, Cost, Profit and Project Report

Introduction to Polyhouse Cultivation and Polyhouse Subsidy

What is polyhouse cultivation? Why most people are showing interest in polyhouse cultivation? Well, since the centuries cultivation of rops is changing with different farming methods and the polyhouse is one of  modern farming methods using controlled environment. Growing crops under controlled environment such as temperature, humidity, and fertilizers with the help of automated systems is called polyhouse cultivation. People are tending towards polyhouse cultivation is due to more profits and one can grow crops throughout the year without depending on environmental factors and also farmers have very few problems with crop pests and diseases in polyhouse growing. Traditional cultivation in open fields has been always risky due to unpredictable climatic conditions and exposing of insect pests and diseases. To satisfy the growing population food and other needs, it is mandatory to grow the crops throughout the year without depending on external weather conditions. One can avail government schemes for polyhouse subsidy in most states of India. As one can expect up to 80% of polyhouse subsidy, you may end up paying only some amount from your pocket. Even some rural banks may offer polyhouse subsidy and loan. Polyhouse horticulture is picking up every year in India as due to the polyhouse subsidy and high profits throughout the year. Apart from this, growing vegetables,  and flowers is very easy when compared to open field cultivation.

Benefits of Polyhouse Cultivation

There are many advantages of growing crops in polyhouse.

  • Plants are grown in a controlled environment.
  • Crops can be grown throughout the year without depending on the season.
  • Insect pests and diseases are less in polyhouse cultivation.
  • External climate does not have any impact on plant growth.
  • Quality of produce is high when compared to open field cultivation.
  • You can expect growth throughout its life-cycle with less transplanting shock.
  • Polyhouse can be maintained with good sanitation.
  • Cropping period is less, hence one expects increased production capacity.
  • Polyhouse has always good drainage and aeration system for better plant growth.
  • Fertilizer application is very easy and controlled automatically.
  • Handling of harvest, grading of products is easy with polyhouse cultivation.
  • The overall yearly crop yield is high.
Types of Polyhouse Cultivation Systems

There are 2 categories of polyhouses can be constructed based on environmental control factors.

Natural Ventilation Polyhouse:

This type of polyhouse will have natural ventilation and Fogger system to prevent pests and diseases. The purpose of naturally ventilated polyhouse is to protect the plants from adverse climatic conditions. They will not have any special environmental control system. These types of polyhouses costs less.

Environmental Control Polyhouse:

In this type of polyhouse system, crops are grown round the year by providing controlled environment factors such as temperature, humidity, fertilizer automation, Co2, and rooting medium. These factors can extend the off-season crop production.

Low tech Polyhouse System:

This polyhouse system can be built with low-cost material and maintaining this system is very easy. Usually, the construction of polyhouse is carried out with local material such as wood and bamboo. Generally, Ultra Violet (UV) film is being used as a cladding material. This type is suitable for cold climatic conditions. Temperature and humidity can be controlled by using shade nets. There won’t be any other controlled devices are used in this type of polyhouses.

Medium tech Polyhouse Sytem:

In this system, the construction of polyhouse is carried out by G. I (galvanized iron) pipes. To prevent any damage from the wind flow, the entire polyhouse structure is fixed to the ground and screws are attached to the structure of the house of the canopy cover. In this system, humidity and temperature are controlled by arranging cooling pads, mist controllers along with Thermostats and exhaust fans. One can adopt these kind of polyhouses in dry and composite weather conditions. This is pretty useful where the plants require good care throughout their life cycle.

Hi-tech Polyhouse System:

Hi-tech polyhouse includes an automatic control system for temperatures, humidity, fertilizers, irrigation and other complete environmental parameters for growing crops all the time.

Benefits of Polyhouse Farming

  • Your plants are grown under controlled temperature thus there is less chances of crop loss or damage.

  • You can grow crops throughout the year and will not have to wait for any particular season.

  • There are less pests and insects in a polyhouse.

  • External climate will not have any impact of the growth of crops.

  • Quality of produce is obviously higher in polyhouse.

  • Good drainage and aeration

  • Propagation of Ornamental Crops can also be done effortlessly in a polyhouse.

  • Poly House gives the right environmental facilities to your plants in any season.

  • It also increases yield for about 5 to 10 times.

  • Less cropping period

  • Fertilizer application is easier and is controlled automatically with the help of drip irrigation.

Polyhouse Cost, Polyhouse Profit, and Polyhouse Subsidy

Polyhouse cost depends on the type system you choose and the construction area. Here are some details of  the construction cost of polyhouse. These figures may change time to time and region to region. Consider this as a ballpark estimate for polyhouse construction.

Cost involved in Polyhouse construction depends on the type of polyhouse:

  • For low cost/low tech polyhouse without exhaust fan systems and cooling pads = Rs.400 to Rs.500/square meter.
  • Medium cost/medium tech polyhouse with cooling pads and exhaust fan systems (without automation) = Rs.900 to Rs.1200/square meter.
  • Hi-tech polyhouse with fully automatic control system = Rs.2500 to Rs.4000/square meter.

There are 2 types polyhouse costs, we can consider.

  • 1. Fixed cost: Land, office room, labor rooms, packing room, cold storage rooms, and other fixed items like drip and sprinkler systems.
  • 2. Variable/Recurring cost: Manures, fertilizers, pest and disease control chemicals, planting materials, electricity, and transportation charges come under recurring expenses.

Polyhouse Cultivation Profits

Polyhouse Project Report and Polyhouse Subsidy for 1 Hectare Rose Cut Flowers

Just to calculate the polyhouse profit, let us take a Rose cut flower cultivation for the project of above mentioned 1 Hectare /2.5 acres polyhouse.

  • Rose plant seedlings/hectare of polyhouse = 60,000
  • Rose flower yield /plant = 100 to 150
  • Quality rose flowers for export purpose/plant = 90 to 100
  • Rose flower cost in the international market = Rs. 8 to 12 per flower.
  • Total exportable rose flowers/ha at the rate of 125 rose flower/plant = 60,000 (total no. of. Rose plants) x 100 Rs (per flower) = Rs.6, 00,000
  • Gross income through exports at the rate of 55 flowers/plant = 6,00,000 x 55 = Rs.3, 30,00,000 (minimum).

Net profit for first year = Gross income – Total cost (fixed plus recurring) = Rs.3, 30,00,000 – Rs.2, 45,75,000  = Rs.84, 25,000 (eighty four lakes and twenty five thousand).

Here are some polyhouse profits / income details for different crops.

  • Gerbera flowers: 42 to 45 lakhs/acre.
  • Ginger: 15 to16 lakhs/acre.
  • Turmeric: 14 to 15 lakhs/acre.
  • Colored Capsicum: 13 to 15 lakhs/acre.
  • Tomato: 12-13 lakhs/acre.
  • Dutch Rose: 34 to 35 lakhs/acre.
  • Cucumber: 9 lakhs/acre.

Note: The above said figures subject to change depending flower quality/ export market demand. However, you can obtain 5 to 7 times of  yield and profits in polyhouse cultivation than traditional open field farming.

Polyhouse Subsidy

There are many states in India encouraging polyhouse cultivation practices. Each state has different subsidy percentages. You can get up to 80% of subsidy.

From above mentioned project (1 hectare cut flowers) 80% of total cost =  0.8 x 2,45,75,000 = 1,96,60,000 (is your subsidy amount) remaining 48 lakh 40 thousand should be spent from your pocket.

Your horticulture department or any NABARD branch  or National Horticulture board is the point of contact to inquire about the exact percentage for polyhouse subsidy for different states in India.
