Planning polyhouse farming in Perumbavoor? Perumbavoor is a small town in Ernakulam district, Kerala, home to about 28,000 people (GeoNames)[1][2], about 340 km from Bengaluru. We have used the monthly climate for Perumbavoor 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 Perumbavoor

March is the hottest month in Perumbavoor, with average daily highs of about 33°C. January has the coolest nights, averaging 23°C.[3] The area gets about 2,653 mm of rain a year, most of it in April to November, peaking in June at about 494 mm. Average humidity stays at 75% or more in April to November, which raises the risk of leaf disease and slows evaporative cooling.

Advantages of protected cultivation in Perumbavoor

  • Year-round crops

    Under cover, cucumber can be grown for the whole year in Perumbavoor, 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 494 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 (April to November), 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 Perumbavoor?

For polyhouse farming in Perumbavoor, the structure decides which months you can crop and what it costs to run. With average highs between 27°C and 33°C through the year, Perumbavoor 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 June (about 494 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.

Protected structures to compare

A nethouse, the lowest-cost option, can grow hardy crops in December to March, when it is mild and fairly dry.

Crops for Perumbavoor

Based on Perumbavoor's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (all year) and brinjal (all year). Cucumber fits all year in a naturally ventilated polyhouse. Lilium and chrysanthemum 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 Perumbavoor.

Polyhouse farming in Perumbavoor: FAQs

Can a polyhouse farm run all year in Perumbavoor?

Which polyhouse is best for Perumbavoor?

With March highs of about 33°C and 67% average humidity in that month, we would start with a naturally ventilated polyhouse.

Which crops should I grow in a polyhouse in Perumbavoor?

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

Is polyhouse farming profitable in Perumbavoor?

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