Planning polyhouse farming in Palakkad? Palakkad is a mid-sized city in Palakkad district, Kerala, home to about 1.3 lakh people (Census 2011)[1], about 270 km from Bengaluru. We have used the monthly climate for Palakkad to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.

Climate for polyhouse farming in Palakkad

March is the hottest month in Palakkad, with average daily highs of about 38°C. January has the coolest nights, averaging 18°C.[2] The area gets about 1,142 mm of rain a year, most of it in May to November, peaking in October at about 192 mm. Average humidity stays at 75% or more in May to December, which raises the risk of leaf disease and slows evaporative cooling. Palakkad sits about 89 m above sea level.[1] On the Köppen–Geiger climate map, Palakkad falls in the tropical savanna (dry winter) zone (Aw).[3]

Area averages (a grid cell of about 50 km) for 2001–2025, from NASA POWER, centred on Palakkad, adjusted for the town's elevation[4]. Rainfall and night temperatures at your plot can differ, especially near hills and the coast.[2]

Advantages of protected cultivation in Palakkad

  • Year-round crops

    Under cover, capsicum can be grown for the whole year in Palakkad, 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 October's 192 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.[5]

Which polyhouse suits Palakkad?

For polyhouse farming in Palakkad, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in February to May, with moderate humidity of about 62%. In that dry air, wet pads can bring a 38°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

Crops for Palakkad

Based on Palakkad'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 Palakkad.

Polyhouse farming in Palakkad: FAQs

Can a polyhouse farm run all year in Palakkad?

Yes, with the right structure. For Palakkad 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 Palakkad?

With March highs of about 38°C and 53% 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 Palakkad?

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 Palakkad?

It can be, if the crop, the structure and the buyers match. In Palakkad, 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.
