Planning polyhouse farming in Raichur? Raichur is a mid-sized city in Raichur district, Karnataka, home to about 2.3 lakh people (GeoNames)[1][2], about 180 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 Raichur
April is the hottest month in Raichur, with average daily highs of about 40°C. December has the coolest nights, averaging 16°C.[3] The area gets about 680 mm of rain a year. The wettest months are July to September, peaking in September at about 151 mm. Average humidity stays at 75% or more in September to October, which raises the risk of leaf disease and slows evaporative cooling. Raichur sits about 407 m above sea level.[2] On the Köppen–Geiger climate map, Raichur falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Raichur
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Raichur, 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
With only about 680 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.
4
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.
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 Raichur?
For polyhouse farming in Raichur, the structure decides which months you can crop and what it costs to run. The heat in Raichur comes with dry air. In March to May, average highs reach 40°C while average humidity is only about 38%. In that dry air, wet pads can bring a 40°C April afternoon down to roughly 30°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 September to December and costs less to run.
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 Raichur
Based on Raichur'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 Raichur.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
180 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] Raichur is large enough for steady local sales to restaurants, hotels and fruit-and-vegetable retailers. Start with a farm size that matches the orders you can confirm. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 180 km away.

Polyhouse farming in Raichur: FAQs
Can a polyhouse farm run all year in Raichur?
Yes, with the right structure. For Raichur 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 Raichur?
With April highs of about 40°C and 36% 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 Raichur?
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 Raichur?
It can be, if the crop, the structure and the buyers match. In Raichur, 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 Raichur?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 420 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.
