Area averages (a grid cell of about 50 km) for 2001–2025, from NASA POWER, centred on Srivilliputhur, adjusted for the town's elevation[5]. Rainfall and night temperatures at your plot can differ, especially near hills and the coast.[3]
Advantages of protected cultivation in Srivilliputhur
1
Year-round crops
Under cover, cucumber can be grown for 10 months a year in Srivilliputhur, 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 October's 252 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 December), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Tamil Nadu can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[6]
Which polyhouse suits Srivilliputhur?
For polyhouse farming in Srivilliputhur, the structure decides which months you can crop and what it costs to run. In Srivilliputhur the heat comes with humidity: during February to May average humidity is about 66%. Wet pads cool much less in humid air: on a typical March afternoon they would only bring 36°C down to about 31°C. So we usually start with a tall naturally ventilated polyhouse with wide roof vents, insect net and a shade screen. A Fan & Pad polyhouse still makes sense if buyers need lettuce through the hottest months, but expect a smaller temperature drop than in dry inland towns.
Plan for heavy rain in October (about 252 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in March at about 6.3 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 December to February, when it is mild and fairly dry.
Crops for Srivilliputhur
Based on Srivilliputhur's climate, the crops with the longest growing windows are cucumber (10 months), capsicum (8 months) and tomato (8 months). Cucumber fits May to February in a naturally ventilated polyhouse. 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 Srivilliputhur.

Polyhouse farming in Srivilliputhur: FAQs
Can a polyhouse farm run all year in Srivilliputhur?
Yes, with the right structure. For Srivilliputhur we would plan a tall naturally ventilated polyhouse with wide vents and insect net. Even then, lettuce is hard to grow in March to May, so plan another crop for those months.
Which polyhouse is best for Srivilliputhur?
With March highs of about 36°C and 58% average humidity in that month, we would start with a tall naturally ventilated polyhouse with wide vents and insect net.
Which crops should I grow in a polyhouse in Srivilliputhur?
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 Srivilliputhur?
It can be, if the crop, the structure and the buyers match. In Srivilliputhur, cucumber and capsicum 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.
