Planning polyhouse farming in Tiruchendur? Tiruchendur is a small town in Thoothukudi district, Tamil Nadu, home to about 32,000 people (GeoNames)[1][2], about 500 km from Bengaluru. This guide works from Tiruchendur'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 Tiruchendur
April is the hottest month in Tiruchendur, with average daily highs of about 32°C. January has the coolest nights, averaging 23°C.[3] The area gets about 1,051 mm of rain a year. The wettest months are October to November, peaking in November at about 236 mm. Average humidity stays at 75% or more in May to January, which raises the risk of leaf disease and slows evaporative cooling.

Advantages of protected cultivation in Tiruchendur
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Tiruchendur, 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 November's 236 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 January), 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.[5]
Which polyhouse suits Tiruchendur?
For polyhouse farming in Tiruchendur, the structure decides which months you can crop and what it costs to run. With average highs between 28°C and 32°C through the year, Tiruchendur suits a naturally ventilated polyhouse for most crops. Fan & Pad cooling is rarely needed; spend the budget on good ventilation, insect net and a shade screen. Plan for heavy rain in November (about 236 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
Sunlight peaks in March at about 6.4 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 September, when it is mild and fairly dry.
Crops for Tiruchendur
Based on Tiruchendur's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (all year) and brinjal (all year). Cucumber fits all year 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 Tiruchendur.

Urban households in Tamil Nadu spent an average of ₹8,325 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Tiruchendur may be small for exotic greens, so plan where the rest of the harvest goes. Thoothukudi, about 30 km away, is the nearest larger market on our list.

Polyhouse farming in Tiruchendur: FAQs
Can a polyhouse farm run all year in Tiruchendur?
Yes, with the right structure. For Tiruchendur we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in March to November, so plan another crop for those months.
Which polyhouse is best for Tiruchendur?
With April highs of about 32°C and 72% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Tiruchendur?
Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Tiruchendur?
It can be, if the crop, the structure and the buyers match. In Tiruchendur, cucumber and chilli pepper 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.
