Advantages of protected cultivation in Kodungallur
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Kodungallur, so you can supply buyers every week instead of one open-field season.
2
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.
3
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.
4
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.
5
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.[4]
Which polyhouse suits Kodungallur?
For polyhouse farming in Kodungallur, 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, Kodungallur 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.
A nethouse, the lowest-cost option, can grow hardy crops in December to March, when it is mild and fairly dry.
Crops for Kodungallur
Based on Kodungallur'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 Kodungallur.

Polyhouse farming in Kodungallur: FAQs
Can a polyhouse farm run all year in Kodungallur?
Yes, with the right structure. For Kodungallur we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in March to July and September to October, so plan another crop for those months.
Which polyhouse is best for Kodungallur?
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 Kodungallur?
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 Kodungallur?
It can be, if the crop, the structure and the buyers match. In Kodungallur, 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.
