Planning polyhouse farming in Malavalli? Malavalli is a small town in Mandya district, Karnataka, home to about 38,000 people (GeoNames)[1][2], about 90 km from Bengaluru. Below we use the town's monthly temperatures, humidity and rainfall to work out which structure fits, which crops to grow and in which months, before you spend on construction.
Climate for polyhouse farming in Malavalli
March is the hottest month in Malavalli, with average daily highs of about 36°C. January has the coolest nights, averaging 15°C.[3] The area gets about 884 mm of rain a year, most of it in May and July to October, peaking in September at about 138 mm. Average humidity stays at 75% or more in June to November, which raises the risk of leaf disease and slows evaporative cooling. Malavalli sits about 610 m above sea level.[2] On the Köppen–Geiger climate map, Malavalli falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Malavalli
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Malavalli, 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 September's 138 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 (June 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 Malavalli?
For polyhouse farming in Malavalli, 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 April, with moderate humidity of about 46%. In that dry air, wet pads can bring a 36°C March afternoon down to roughly 28°C inside a Fan & Pad polyhouse, cool enough for lettuce and other leafy greens. 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.
Sunlight peaks in March at about 6.6 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 February and June, when it is mild and fairly dry.
Crops for Malavalli
Based on Malavalli'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 strawberry 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 Malavalli.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
90 kmto Bengaluru, the nearest metro (straight line)
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 Malavalli may be small for exotic greens, so plan where the rest of the harvest goes. Mysore, about 50 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Bengaluru is within a day's delivery, about 90 km away.

Polyhouse farming in Malavalli: FAQs
Can a polyhouse farm run all year in Malavalli?
Yes, with the right structure. For Malavalli we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.
Which polyhouse is best for Malavalli?
With March highs of about 36°C and 41% 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 Malavalli?
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 Malavalli?
It can be, if the crop, the structure and the buyers match. In Malavalli, 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.
