Planning polyhouse farming in Kharagpur? Kharagpur is a mid-sized city in Paschim Medinipur district, West Bengal, home to about 2.1 lakh people (Census 2011)[1], about 110 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 Kharagpur

April is the hottest month in Kharagpur, with average daily highs of about 38°C. January has the coolest nights, averaging 10°C.[2] The area gets about 1,516 mm of rain a year, most of it in May to October, peaking in July at about 314 mm. Average humidity stays at 75% or more in June to December, which raises the risk of leaf disease and slows evaporative cooling. Kharagpur sits about 61 m above sea level.[1] On the Köppen–Geiger climate map, Kharagpur falls in the tropical savanna (dry winter) zone (Aw).[3]

Advantages of protected cultivation in Kharagpur

  • Year-round crops

    Under cover, cucumber can be grown for 10 months a year in Kharagpur, so you can supply buyers every week instead of one open-field season.

  • 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.

  • Less water

    Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 314 mm of rain off the crop and the soil.

  • 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.

  • Subsidy eligible

    Polyhouse, shade net and nethouse projects in West Bengal can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]

Which polyhouse suits Kharagpur?

For polyhouse farming in Kharagpur, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in March to June, with moderate humidity of about 65%. In that dry air, wet pads can bring a 38°C April afternoon down to roughly 33°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. Capsicum, cucumber and tomato do well in a naturally ventilated polyhouse with a shade screen. If you want one structure, decide by crop: greens all year point to Fan & Pad; vine crops point to a naturally ventilated house.

Protected structures to compare

Plan for heavy rain in July (about 314 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 Kharagpur

Based on Kharagpur's climate, the crops with the longest growing windows are cucumber (10 months), chilli pepper (10 months) and brinjal (10 months). Cucumber fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Kharagpur.

Polyhouse farming in Kharagpur: FAQs

Can a polyhouse farm run all year in Kharagpur?

Yes, with the right structure. For Kharagpur we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops. Even then, lettuce is hard to grow in April to September, so plan another crop for those months.

Which polyhouse is best for Kharagpur?

With April highs of about 38°C and 58% average humidity in that month, we would start with Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.

Which crops should I grow in a polyhouse in Kharagpur?

Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Is polyhouse farming profitable in Kharagpur?

It can be, if the crop, the structure and the buyers match. In Kharagpur, cucumber and chilli pepper 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 Kharagpur?

Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,270 km away, and we have built 2 projects in West Bengal.
