Advantages of protected cultivation in Sanduru
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Sanduru, 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
With only about 634 mm of rain a year here, drip irrigation under cover saves water: less is lost to evaporation and run-off than in the open field.
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 October), 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 Sanduru?
For polyhouse farming in Sanduru, 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 May, with moderate humidity of about 45%. In that dry air, wet pads can bring a 37°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 October to February and June to August, when it is mild and fairly dry.
Crops for Sanduru
Based on Sanduru'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 Sanduru.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
260 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 Sanduru may be small for exotic greens, so plan where the rest of the harvest goes. Hosapete, about 30 km away, is the nearest larger market on our list.

Polyhouse farming in Sanduru: FAQs
Can a polyhouse farm run all year in Sanduru?
Yes, with the right structure. For Sanduru we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops. Even then, lettuce is hard to grow in May, so plan another crop for those months.
Which polyhouse is best for Sanduru?
With April highs of about 37°C and 45% 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 Sanduru?
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 Sanduru?
It can be, if the crop, the structure and the buyers match. In Sanduru, 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.
Does Kryzen build polyhouses in Sanduru?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 430 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.
