Planning polyhouse farming in Shahpur? Shahpur is a town in Karnataka, home to about 53,000 people (GeoNames)[1][2], about 190 km from Hyderabad. Below we use the town's monthly temperatures, humidity and rainfall to work out which structure fits, which crops to grow and in which months, before you spend on construction.

Climate for polyhouse farming in Shahpur

April is the hottest month in Shahpur, with average daily highs of about 40°C. December has the coolest nights, averaging 15°C.[3] The area gets about 655 mm of rain a year. The wettest months are July to September, peaking in September at about 149 mm. Average humidity stays at 75% or more in September to October, which raises the risk of leaf disease and slows evaporative cooling. Shahpur sits about 428 m above sea level.[2] On the Köppen–Geiger climate map, Shahpur falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Shahpur

  • Year-round crops

    Under cover, cucumber can be grown for the whole year in Shahpur, so you can supply buyers every week instead of one open-field season.

  • Better yield and price

    Plants grow without rain, hail and wind damage, so yields are higher and more even, and clean, graded produce sells at a better price, especially off-season.

  • Less water

    With only about 655 mm of rain a year here, drip irrigation under cover saves water: less is lost to evaporation and run-off than in the open field.

  • Less pesticides

    Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (September to October), so you spray less often.

  • Subsidy eligible

    Polyhouse, shade net and nethouse projects in Karnataka can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]

Which polyhouse suits Shahpur?

For polyhouse farming in Shahpur, the structure decides which months you can crop and what it costs to run. The heat in Shahpur comes with dry air. In March to May, average highs reach 40°C while average humidity is only about 35%. In that dry air, wet pads can bring a 40°C April afternoon down to roughly 30°C inside a Fan & Pad polyhouse, cool enough for lettuce and other leafy greens. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from September to December and costs less to run.

Protected structures to compare

Sunlight peaks in April at about 6.8 kWh per m² a day, so add a shade screen for leafy greens in the brightest months. A nethouse, the lowest-cost option, can grow hardy crops in October to January and June, when it is mild and fairly dry.

Crops for Shahpur

Based on Shahpur's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (all year) and brinjal (all year). Cucumber fits all year with Fan & Pad cooling. Lilium and broccoli are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in Shahpur.

Polyhouse farming in Shahpur: FAQs

Can a polyhouse farm run all year in Shahpur?

Yes, with the right structure. For Shahpur we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to May, so plan another crop for those months.

Which polyhouse is best for Shahpur?

With April highs of about 40°C and 34% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.

Which crops should I grow in a polyhouse in Shahpur?

Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Is polyhouse farming profitable in Shahpur?

It can be, if the crop, the structure and the buyers match. In Shahpur, cucumber and chilli pepper have the longest seasons under cover. Confirm prices and volumes with buyers first; our Detailed Project Report works out the cost, yield and returns for your plot.

Does Kryzen build polyhouses in Shahpur?

Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 340 km away, and we have built 38 projects in Karnataka.

Is there a subsidy for polyhouse or hydroponic farms in Karnataka?

Yes. Protected cultivation projects in Karnataka can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department. Check the current rate and area limit when you apply.
