Planning polyhouse farming in Thoubal? Thoubal is a town in Thoubal district, Manipur, home to about 46,000 people (GeoNames)[1][2], about 620 km from Kolkata. This guide works from Thoubal's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.
Climate for polyhouse farming in Thoubal
April is the hottest month in Thoubal, with average daily highs of about 30°C. January has the coolest nights, averaging 7°C.[3] The area gets about 1,267 mm of rain a year, most of it in April to October, peaking in July at about 218 mm. Average humidity stays at 75% or more in May to November, which raises the risk of leaf disease and slows evaporative cooling. Thoubal sits about 765 m above sea level.[2] On the Köppen–Geiger climate map, Thoubal falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Thoubal
1
Year-round crops
Under cover, tomato can be grown for 10 months a year in Thoubal, 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 218 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 November), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Manipur can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Thoubal?
For polyhouse farming in Thoubal, the structure decides which months you can crop and what it costs to run. With average highs between 22°C and 30°C through the year, Thoubal 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 218 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
Based on Thoubal's climate, the crops with the longest growing windows are tomato (10 months), capsicum (9 months) and chilli pepper (9 months). Tomato fits February to November 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 Thoubal.

Urban households in Manipur spent an average of ₹6,005 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Local demand in Thoubal may be small for exotic greens, so plan where the rest of the harvest goes. Imphal, about 20 km away, is the nearest larger market on our list.
