Planning polyhouse farming in Ramanagaram? Ramanagaram is a town in Karnataka, home to about 95,000 people (GeoNames)[1][2], about 40 km from Bengaluru. This guide works from Ramanagaram'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 Ramanagaram
April is the hottest month in Ramanagaram, with average daily highs of about 36°C. January has the coolest nights, averaging 14°C.[3] The area gets about 834 mm of rain a year, most of it in May and August to October, peaking in October at about 145 mm. Average humidity stays at 75% or more in July to December, which raises the risk of leaf disease and slows evaporative cooling. Ramanagaram sits about 747 m above sea level.[2] On the Köppen–Geiger climate map, Ramanagaram falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Ramanagaram
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Ramanagaram, 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 October's 145 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 (July to December), 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 Ramanagaram?
For polyhouse farming in Ramanagaram, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in March to May, with moderate humidity of about 53%. In that dry air, wet pads can bring a 36°C April afternoon down to roughly 30°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 to July, when it is mild and fairly dry.
Crops for Ramanagaram
Based on Ramanagaram'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. Strawberry is hard to time here, so we would leave it out of the first season. These are the crops we would plan first for polyhouse farming in Ramanagaram.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
40 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 Ramanagaram may be small for exotic greens, so plan where the rest of the harvest goes. Bengaluru, about 40 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Bengaluru is within a day's delivery, about 40 km away.

Polyhouse farming in Ramanagaram: FAQs
Can a polyhouse farm run all year in Ramanagaram?
Yes, with the right structure. For Ramanagaram we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.
Which polyhouse is best for Ramanagaram?
With April highs of about 36°C and 50% 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 Ramanagaram?
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 Ramanagaram?
It can be, if the crop, the structure and the buyers match. In Ramanagaram, 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.
