Planning polyhouse farming in Korba? Korba is a large city in Korba district, Chhattisgarh, home to about 4.2 lakh people (GeoNames)[1][2], about 580 km from Kolkata. 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 Korba
May is the hottest month in Korba, with average daily highs of about 43°C.

Advantages of protected cultivation in Korba
1
ఏడాది పొడవునా పంటలు
Under cover, chilli pepper can be grown for 10 months a year in Korba, so you can supply buyers every week instead of one open-field season.
2
మెరుగైన దిగుబడి మరియు ధర
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
తక్కువ నీరు
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps August's 343 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 (July to October), so you spray less often.

Which polyhouse suits Korba?
For polyhouse farming in Korba, the structure decides which months you can crop and what it costs to run. The heat in Korba comes with dry air. In April to May, average highs reach 43°C while average humidity is only about 28%. In that dry air, wet pads can bring a 43°C May 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 February and July to November and costs less to run.
Plan for heavy rain in August (about 343 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May 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 February and October to December, when it is mild and fairly dry.
Crops for Korba
Based on Korba's climate, the crops with the longest growing windows are chilli pepper (10 months), lettuce (10 months) and tomato (9 months). Chilli pepper fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Korba.

₹5,114Spending per person per month, urban Chhattisgarh, 2023–24[6]
580 kmto Kolkata, the nearest metro (straight line)
Urban households in Chhattisgarh spent an average of ₹5,114 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Korba 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.

Polyhouse farming in Korba: FAQs
Can a polyhouse farm run all year in Korba?
Yes, with the right structure. For Korba we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to June, so plan another crop for those months.
Which polyhouse is best for Korba?
With May highs of about 43°C and 29% 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 Korba?
Going by the monthly climate, chilli pepper, lettuce and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Korba?
It can be, if the crop, the structure and the buyers match. In Korba, chilli pepper and lettuce 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 Korba?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 810 km away, and we have built 3 projects in Chhattisgarh.
Is there a subsidy for polyhouse or hydroponic farms in Chhattisgarh?
Yes. Protected cultivation projects in Chhattisgarh 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.
