Planning polyhouse farming in Kailasahar? Kailasahar is a small town in Unakoti district, Tripura, home to about 22,000 people (GeoNames)[1][2], about 420 km from Kolkata. We have used the monthly climate for Kailasahar to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.
Climate for polyhouse farming in Kailasahar
April is the hottest month in Kailasahar, with average daily highs of about 34°C. January has the coolest nights, averaging 10°C.[3] The area gets about 3,025 mm of rain a year, most of it in April to October, peaking in June at about 574 mm. Average humidity stays at 75% or more in May to December, which raises the risk of leaf disease and slows evaporative cooling. Kailasahar sits about 21 m above sea level.[2] On the Köppen–Geiger climate map, Kailasahar falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Kailasahar
1
Year-round crops
Under cover, chilli pepper can be grown for 10 months a year in Kailasahar, 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 June's 574 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 (May to December), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Tripura can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Kailasahar?
For polyhouse farming in Kailasahar, the structure decides which months you can crop and what it costs to run. With average highs between 24°C and 34°C through the year, Kailasahar suits a naturally ventilated polyhouse for most crops. Fan & Pad cooling is rarely needed; spend the budget on good ventilation, insect net and a shade screen. Plan for heavy rain in June (about 574 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
A nethouse, the lowest-cost option, can grow hardy crops in November to March, when it is mild and fairly dry.
Crops for Kailasahar
Based on Kailasahar's climate, the crops with the longest growing windows are chilli pepper (10 months), cucumber (9 months) and brinjal (8 months). Chilli pepper fits February to March and May to December in a naturally ventilated polyhouse. 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 Kailasahar.

Urban households in Tripura spent an average of ₹8,118 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Kailasahar may be small for exotic greens, so plan where the rest of the harvest goes.

Polyhouse farming in Kailasahar: FAQs
Can a polyhouse farm run all year in Kailasahar?
Yes, with the right structure. For Kailasahar we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in April to September, so plan another crop for those months.
Which polyhouse is best for Kailasahar?
With April highs of about 34°C and 69% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Kailasahar?
Going by the monthly climate, tomato, capsicum and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Kailasahar?
It can be, if the crop, the structure and the buyers match. In Kailasahar, chilli pepper and cucumber 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 Kailasahar?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,780 km away, and we have built one project in Tripura.
Is there a subsidy for polyhouse or hydroponic farms in Tripura?
Yes. Protected cultivation projects in Tripura 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.
