Planning polyhouse farming in Jorhat? Jorhat is a mid-sized city in Jorhat district, Assam, home to about 1.5 lakh people (Census 2011)[1], about 750 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 Jorhat
June is the hottest month in Jorhat, with average daily highs of about 32°C. January has the coolest nights, averaging 11°C.[2] The area gets about 2,133 mm of rain a year, most of it in April to October, peaking in July at about 419 mm. Average humidity stays at 75% or more in June to December, which raises the risk of leaf disease and slows evaporative cooling. Jorhat sits about 116 m above sea level.[1] On the Köppen–Geiger climate map, Jorhat falls in the humid subtropical with dry winters zone (Cwa).[3]

Advantages of protected cultivation in Jorhat
1
Year-round crops
Under cover, chilli pepper can be grown for 11 months a year in Jorhat, 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 July's 419 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 (June to December), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Assam can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Jorhat?
For polyhouse farming in Jorhat, the structure decides which months you can crop and what it costs to run. With average highs between 21°C and 32°C through the year, Jorhat 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 July (about 419 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 February to March and November, when it is mild and fairly dry.
Crops for Jorhat
Based on Jorhat's climate, the crops with the longest growing windows are chilli pepper (11 months), cucumber (10 months) and brinjal (10 months). Chilli pepper fits February 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 Jorhat.

Urban households in Assam spent an average of ₹6,913 per person per month in 2023–24, close to the all-India urban average of ₹7,078.[5] Jorhat 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 Jorhat: FAQs
Can a polyhouse farm run all year in Jorhat?
Yes, with the right structure. For Jorhat we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in June to September, so plan another crop for those months.
Which polyhouse is best for Jorhat?
With June highs of about 32°C and 78% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Jorhat?
Going by the monthly climate, capsicum, chilli pepper and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Jorhat?
It can be, if the crop, the structure and the buyers match. In Jorhat, 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 Jorhat?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 2,070 km away, and we have built 2 projects in Assam.
Is there a subsidy for polyhouse or hydroponic farms in Assam?
Yes. Protected cultivation projects in Assam 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.
