Polyhouse farming in Sedam: aerial view of a large protected cultivation farm with polyhouses

Planning polyhouse farming in Sedam? Sedam is a small town in Kalaburgi district, Karnataka, home to about 39,000 people (Census 2011)[1], about 130 km from Hyderabad. This guide works from Sedam's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.

Climate for polyhouse farming in Sedam

May is the hottest month in Sedam, with average daily highs of about 40°C. December has the coolest nights, averaging 15°C.[2] The area gets about 779 mm of rain a year, most of it in June to September, peaking in August at about 166 mm. Average humidity stays at 75% or more in August to October, which raises the risk of leaf disease and slows evaporative cooling. Sedam sits about 407 m above sea level.[1] On the Köppen–Geiger climate map, Sedam falls in the hot semi-arid zone (BSh).[3]

Advantages of protected cultivation in Sedam

  • Year-round crops

    Under cover, cucumber can be grown for the whole year in Sedam, 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

    Drip irrigation under cover uses less water than flood irrigation, and the roof keeps August's 166 mm of rain off the crop and the soil.

  • Less pesticides

    Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (August 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.[4]

Which polyhouse suits Sedam?

For polyhouse farming in Sedam, the structure decides which months you can crop and what it costs to run. The heat in Sedam comes with dry air. In April to May, average highs reach 40°C while average humidity is only about 37%. In that dry air, wet pads can bring a 40°C May afternoon down to roughly 31°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from July to December and costs less to run.

Protected structures to compare

Sunlight peaks in April at about 6.6 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, when it is mild and fairly dry.

Crops for Sedam

Based on Sedam'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 strawberry 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 Sedam.

Urban households in Karnataka spent an average of ₹8,169 per person per month in 2023–24, above the all-India urban average of ₹7,078.[5] Local demand in Sedam may be small for exotic greens, so plan where the rest of the harvest goes. Kalaburagi, about 50 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 130 km away.

Polyhouse farming in Sedam: FAQs

Can a polyhouse farm run all year in Sedam?

Yes, with the right structure. For Sedam 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 Sedam?

With May highs of about 40°C and 38% 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 Sedam?

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 Sedam?

It can be, if the crop, the structure and the buyers match. In Sedam, 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 Sedam?

Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 360 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.
