Polyhouse farming in Malda: aerial view of a large protected cultivation farm with polyhouses

Planning polyhouse farming in Malda? Malda is a mid-sized city in Malda district, West Bengal, home to about 2.1 lakh people (Census 2011)[1], about 270 km from Kolkata. This guide works from Malda'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 Malda

April is the hottest month in Malda, with average daily highs of about 38°C. January has the coolest nights, averaging 9°C.[2] The area gets about 1,317 mm of rain a year, most of it in May to October, peaking in July at about 282 mm. Average humidity stays at 75% or more in July to November, which raises the risk of leaf disease and slows evaporative cooling. Malda sits about 17 m above sea level.[1] On the Köppen–Geiger climate map, Malda falls in the tropical savanna (dry winter) zone (Aw).[3]

Advantages of protected cultivation in Malda

  • Year-round crops

    Under cover, chilli pepper can be grown for 10 months a year in Malda, 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 282 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 (July to November), 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 Malda?

For polyhouse farming in Malda, 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 52%. In that dry air, wet pads can bring a 38°C April afternoon down to roughly 30°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 282 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.

Crops for Malda

Based on Malda's climate, the crops with the longest growing windows are chilli pepper (10 months), capsicum (9 months) and cucumber (9 months). Chilli pepper fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Malda.

Polyhouse farming in Malda: FAQs

Can a polyhouse farm run all year in Malda?

Yes, with the right structure. For Malda 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 Malda?

With April highs of about 38°C and 43% 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 Malda?

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

Is polyhouse farming profitable in Malda?

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

Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,430 km away, and we have built 2 projects in West Bengal.

Is there a subsidy for polyhouse or hydroponic farms in West Bengal?

Yes. Protected cultivation projects in West Bengal 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.
