Planning polyhouse farming in Malur? Malur is a town in Kolar district, Karnataka, home to about 40,000 people (GeoNames)[1][2], about 40 km from Bengaluru. This guide works from Malur'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 Malur
April is the hottest month in Malur, with average daily highs of about 35°C. January has the coolest nights, averaging 14°C.[3] The area gets about 877 mm of rain a year. The wettest months are May and August to October, peaking in October at about 157 mm. Average humidity stays at 75% or more in August to December, which raises the risk of leaf disease and slows evaporative cooling. Malur sits about 909 m above sea level, so nights run cooler than in the plains around it.[2] On the Köppen–Geiger climate map, Malur falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Malur
1
ஆண்டு முழுவதும் பயிர்கள்
Under cover, capsicum can be grown for the whole year in Malur, so you can supply buyers every week instead of one open-field season.
2
சிறந்த விளைச்சலும் விலையும்
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
குறைந்த நீர்
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.

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 Malur?
For polyhouse farming in Malur, 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 6.8 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 Malur
Based on Malur'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 Malur.

₹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 Malur may be small for exotic greens, so plan where the rest of the harvest goes. Hosur, about 30 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.

Yes, with the right structure. For Malur we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.
Which polyhouse is best for Malur?
With April highs of about 35°C and 52% 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 Malur?
Going by the monthly climate, capsicum, tomato and cucumber have the longest growing windows. Confirm prices and volumes with buyers before you plant.
