Planning polyhouse farming in Puttur? Puttur is a town in Dakshina Kannada district, Karnataka, home to about 53,000 people (GeoNames)[1][2], about 260 km from Bengaluru. This guide works from Puttur'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 Puttur
March is the hottest month in Puttur, with average daily highs of about 34°C.

Average humidity stays at 75% or more in May to November, which raises the risk of leaf disease and slows evaporative cooling. Puttur sits about 87 m above sea level.[2] On the Köppen–Geiger climate map, Puttur falls in the tropical monsoon zone (Am).[4]

Advantages of protected cultivation in Puttur
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Puttur, 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 July's 972 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 (May to November), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Karnataka can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Puttur?
For polyhouse farming in Puttur, the structure decides which months you can crop and what it costs to run. With average highs between 27°C and 34°C through the year, Puttur 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 July (about 972 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. A nethouse, the lowest-cost option, can grow hardy crops in November to April, when it is mild and fairly dry.
Crops for Puttur
Based on Puttur's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (11 months) and brinjal (11 months). 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 Puttur.

Urban households in Karnataka spent an average of ₹8,169 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Puttur may be small for exotic greens, so plan where the rest of the harvest goes. Mangaluru, about 40 km away, is the nearest larger market on our list.

Polyhouse farming in Puttur: FAQs
Can a polyhouse farm run all year in Puttur?
Yes, with the right structure. For Puttur we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in April to June, so plan another crop for those months.
Which polyhouse is best for Puttur?
With March highs of about 34°C and 62% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Puttur?
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 Puttur?
It can be, if the crop, the structure and the buyers match. In Puttur, 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.
Does Kryzen build polyhouses in Puttur?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 590 km away, and we have built 38 projects in Karnataka.
Is there a subsidy for polyhouse or hydroponic farms in Karnataka?
Yes. Protected cultivation projects in Karnataka 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.
