Planning polyhouse farming in Malappuram? Malappuram is a mid-sized city in Malappuram district, Kerala, home to about 1 lakh people (GeoNames)[1][2], about 270 km from Bengaluru. This guide works from Malappuram'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 Malappuram

March is the hottest month in Malappuram, with average daily highs of about 37°C. January has the coolest nights, averaging 20°C.[3] The area gets about 1,986 mm of rain a year, most of it in May to November, peaking in June at about 393 mm. Average humidity stays at 75% or more in May to December, which raises the risk of leaf disease and slows evaporative cooling. Malappuram sits about 39 m above sea level.[2] On the Köppen–Geiger climate map, Malappuram falls in the tropical monsoon zone (Am).[4]

Advantages of protected cultivation in Malappuram

  • Year-round crops

    Under cover, capsicum can be grown for the whole year in Malappuram, 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 June's 393 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 (May to December), so you spray less often.

  • Subsidy eligible

    Polyhouse, shade net and nethouse projects in Kerala can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[6]

Which polyhouse suits Malappuram?

For polyhouse farming in Malappuram, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in January to April, with moderate humidity of about 64%. In that dry air, wet pads can bring a 37°C March afternoon down to roughly 32°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 June (about 393 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in March at about 6.4 kWh per m² a day, so add a shade screen for leafy greens in the brightest months.

Crops for Malappuram

Based on Malappuram's climate, the crops with the longest growing windows are capsicum (all year), tomato (all year) and cucumber (all year). Capsicum fits all year with Fan & Pad cooling. Lilium and carnation 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 Malappuram.

Polyhouse farming in Malappuram: FAQs

Can a polyhouse farm run all year in Malappuram?

Yes, with the right structure. For Malappuram 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 February to May, so plan another crop for those months.

Which polyhouse is best for Malappuram?

With March highs of about 37°C and 61% 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 Malappuram?

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

Is polyhouse farming profitable in Malappuram?

It can be, if the crop, the structure and the buyers match. In Malappuram, capsicum and tomato 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 Malappuram?

Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 800 km away.

Is there a subsidy for polyhouse or hydroponic farms in Kerala?

Yes. Protected cultivation projects in Kerala 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.
