Planning polyhouse farming in Mangaluru? Mangaluru is a large city in Dakshina Kannada district, Karnataka, home to about 5 lakh people (GeoNames)[1][2], about 300 km from Bengaluru. We have used the monthly climate for Mangaluru 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 Mangaluru
March is the hottest month in Mangaluru, with average daily highs of about 34°C. January has the coolest nights, averaging 21°C.[3] The area gets about 3,615 mm of rain a year, most of it in May to October, peaking in July at about 972 mm. Average humidity stays at 75% or more in May to November, which raises the risk of leaf disease and slows evaporative cooling. Mangaluru sits about 22 m above sea level.[2] On the Köppen–Geiger climate map, Mangaluru falls in the tropical monsoon zone (Am).[4]

Advantages of protected cultivation in Mangaluru
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Mangaluru, 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 Mangaluru?
For polyhouse farming in Mangaluru, 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, Mangaluru 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 6.5 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 Mangaluru
Based on Mangaluru'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 Mangaluru.

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] Mangaluru is large enough for steady local sales to restaurants, hotels and fruit-and-vegetable retailers. Start with a farm size that matches the orders you can confirm.

Polyhouse farming in Mangaluru: FAQs
Can a polyhouse farm run all year in Mangaluru?
Yes, with the right structure. For Mangaluru 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 Mangaluru?
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 Mangaluru?
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 Mangaluru?
It can be, if the crop, the structure and the buyers match. In Mangaluru, 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 Mangaluru?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 570 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.
