Planning polyhouse farming in Imphal? Imphal is a mid-sized city in Manipur, home to about 2.7 lakh people (Census 2011)[1], about 620 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 Imphal
May is the hottest month in Imphal, with average daily highs of about 30°C. January has the coolest nights, averaging 8°C.[2] The area gets about 1,351 mm of rain a year, most of it in April to October, peaking in July at about 233 mm. Average humidity stays at 75% or more in May to November, which raises the risk of leaf disease and slows evaporative cooling. Imphal sits about 786 m above sea level.[1] On the Köppen–Geiger climate map, Imphal falls in the humid subtropical with dry winters zone (Cwa).[3]

Advantages of protected cultivation in Imphal
1
Year-round crops
Under cover, tomato can be grown for 11 months a year in Imphal, 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 233 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 Imphal?
For polyhouse farming in Imphal, 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, Imphal 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 233 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 Imphal
Based on Imphal's climate, the crops with the longest growing windows are tomato (11 months), capsicum (9 months) and cucumber (9 months). Tomato 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 Imphal.
