Advantages of protected cultivation in Kolar
1
ఏడాది పొడవునా పంటలు
Under cover, capsicum can be grown for the whole year in Kolar, so you can supply buyers every week instead of one open-field season.
2
మెరుగైన దిగుబడి మరియు ధర
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
తక్కువ నీరు
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps October's 157 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 (August to December), so you spray less often.

Which polyhouse suits Kolar?
For polyhouse farming in Kolar, 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 54%. In that dry air, wet pads can bring a 35°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 April at about 6.7 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 Kolar
Based on Kolar'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. These are the crops we would plan first for polyhouse farming in Kolar.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
60 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 Kolar may be small for exotic greens, so plan where the rest of the harvest goes. For premium vegetable and flower buyers, Bengaluru is within a day's delivery, about 60 km away.
