Planning polyhouse farming in Nagaon? Nagaon is a mid-sized city in Assam, home to about 1.5 lakh people (Census 2011)[1], about 610 km from Kolkata. We have used the monthly climate for Nagaon 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 Nagaon
May is the hottest month in Nagaon, with average daily highs of about 33°C. January has the coolest nights, averaging 10°C.[2] The area gets about 1,630 mm of rain a year, most of it in April to September, peaking in July at about 290 mm. Average humidity stays at 75% or more in June to December, which raises the risk of leaf disease and slows evaporative cooling. Nagaon sits about 54 m above sea level.[1] On the Köppen–Geiger climate map, Nagaon falls in the tropical savanna (dry winter) zone (Aw).[3]

Advantages of protected cultivation in Nagaon
1
Year-round crops
Under cover, chilli pepper can be grown for 11 months a year in Nagaon, 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 290 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 Nagaon?
For polyhouse farming in Nagaon, the structure decides which months you can crop and what it costs to run. With average highs between 22°C and 33°C through the year, Nagaon 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 290 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 October to November, when it is mild and fairly dry.
Crops for Nagaon
Based on Nagaon's climate, the crops with the longest growing windows are chilli pepper (11 months), cucumber (9 months) and brinjal (9 months). Chilli pepper fits February to December in a naturally ventilated polyhouse. Lilium and orchids 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 Nagaon.

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] Local demand in Nagaon may be small for exotic greens, so plan where the rest of the harvest goes.

Polyhouse farming in Nagaon: FAQs
Can a polyhouse farm run all year in Nagaon?
Yes, with the right structure. For Nagaon 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 Nagaon?
With May highs of about 33°C and 72% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Nagaon?
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 Nagaon?
It can be, if the crop, the structure and the buyers match. In Nagaon, 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 Nagaon?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,910 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.
