Planning polyhouse farming in Wadi? Wadi is a small town in Kalaburgi district, Karnataka, home to about 38,000 people (GeoNames)[1][2], about 160 km from Hyderabad. This guide works from Wadi'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 Wadi
May is the hottest month in Wadi, with average daily highs of about 41°C. December has the coolest nights, averaging 15°C.[3] The area gets about 721 mm of rain a year, most of it in June to September, peaking in September at about 164 mm. Average humidity stays at 75% or more in August to October, which raises the risk of leaf disease and slows evaporative cooling. Wadi sits about 411 m above sea level.[2] On the Köppen–Geiger climate map, Wadi falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Wadi
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Wadi, so you can supply buyers every week instead of one open-field season.
2
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.
3
Less water
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps September's 164 mm of rain off the crop and the soil.
4
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.
5
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 Wadi?
For polyhouse farming in Wadi, the structure decides which months you can crop and what it costs to run. The heat in Wadi comes with dry air. In March to May, average highs reach 41°C while average humidity is only about 33%. In that dry air, wet pads can bring a 41°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 August to December and costs less to run.
Sunlight peaks in April at about 6.7 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 Wadi
Based on Wadi'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 carnation 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 Wadi.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
160 kmto Hyderabad, the nearest metro (straight line)
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.[6] Local demand in Wadi may be small for exotic greens, so plan where the rest of the harvest goes. Kalaburagi, about 40 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 160 km away.
Polyhouse farming in Wadi with Kryzen

Polyhouse farming in Wadi: FAQs
Can a polyhouse farm run all year in Wadi?
Yes, with the right structure. For Wadi we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to June, so plan another crop for those months.
Which polyhouse is best for Wadi?
With May highs of about 41°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 Wadi?
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 Wadi?
It can be, if the crop, the structure and the buyers match. In Wadi, 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 Wadi?
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.
