Advantages of protected cultivation in Davanagere
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Davanagere, 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 July's 324 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 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 Davanagere?
For polyhouse farming in Davanagere, 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 51%. In that dry air, wet pads can bring a 37°C April afternoon down to roughly 31°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. 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.
Plan for heavy rain in July (about 324 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.9 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 January, when it is mild and fairly dry.
Crops for Davanagere
Based on Davanagere'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 Davanagere.

Polyhouse farming in Davanagere: FAQs
Can a polyhouse farm run all year in Davanagere?
Yes, with the right structure. For Davanagere 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 April to May, so plan another crop for those months.
Which polyhouse is best for Davanagere?
With April highs of about 37°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 Davanagere?
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 Davanagere?
It can be, if the crop, the structure and the buyers match. In Davanagere, 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 Davanagere?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 440 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.
