Advantages of protected cultivation in Adyar
1
ఏడాది పొడవునా పంటలు
Under cover, capsicum can be grown for the whole year in Adyar, 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 July's 972 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 (May to November), so you spray less often.

Which polyhouse suits Adyar?
For polyhouse farming in Adyar, 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 April, with moderate humidity of about 64%. In that dry air, wet pads can bring a 35°C March afternoon down to roughly 30°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 972 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in March at about 6.5 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 April, when it is mild and fairly dry.
Crops for Adyar
Based on Adyar's climate, the crops with the longest growing windows are capsicum (all year), cucumber (all year) and chilli pepper (all year). Capsicum fits all year with Fan & Pad cooling. Lilium and chrysanthemum 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 Adyar.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
290 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 Adyar may be small for exotic greens, so plan where the rest of the harvest goes. Mangaluru, about 10 km away, is the nearest larger market on our list.

Polyhouse farming in Adyar: FAQs
Can a polyhouse farm run all year in Adyar?
Yes, with the right structure. For Adyar 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 March to August, so plan another crop for those months.
Which polyhouse is best for Adyar?
With March highs of about 35°C and 62% 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 Adyar?
Going by the monthly climate, capsicum, cucumber and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Adyar?
It can be, if the crop, the structure and the buyers match. In Adyar, capsicum and cucumber 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 Adyar?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 580 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.
