Planning polyhouse farming in Pattukkottai? Pattukkottai is a town in Thanjavur district, Tamil Nadu, home to about 73,000 people (GeoNames)[1][2], about 310 km from Chennai. This guide works from Pattukkottai'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 Pattukkottai

April is the hottest month in Pattukkottai, with average daily highs of about 35°C. January has the coolest nights, averaging 21°C.[3] The area gets about 1,019 mm of rain a year, most of it in September to December, peaking in November at about 253 mm. Average humidity stays at 75% or more in October to January, which raises the risk of leaf disease and slows evaporative cooling. Pattukkottai sits about 5 m above sea level.[2] On the Köppen–Geiger climate map, Pattukkottai falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Pattukkottai

  • Year-round crops

    A polyhouse stretches the season: in Pattukkottai cucumber can be grown for about 8 months a year under cover, longer than in the open field.

  • 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.

  • Less water

    Drip irrigation under cover uses less water than flood irrigation, and the roof keeps November's 253 mm of rain off the crop and the soil.

  • Less pesticides

    Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (October to January), so you spray less often.

  • 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 Pattukkottai?

For polyhouse farming in Pattukkottai, the structure decides which months you can crop and what it costs to run. In Pattukkottai the heat comes with humidity: during March to August average humidity is about 66%. Wet pads cool much less in humid air: on a typical April afternoon they would only bring 35°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.

Protected structures to compare

Plan for heavy rain in November (about 253 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 January to March and August, when it is mild and fairly dry.

Crops for Pattukkottai

Based on Pattukkottai's climate, the crops with the longest growing windows are cucumber (8 months), chilli pepper (6 months) and brinjal (6 months). Cucumber fits August to March 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 Pattukkottai.

Polyhouse farming in Pattukkottai: FAQs

Can a polyhouse farm run all year in Pattukkottai?

Yes, with the right structure. For Pattukkottai we would plan a tall naturally ventilated polyhouse with wide vents and insect net. Even then, lettuce is hard to grow in March to October, so plan another crop for those months.

Which polyhouse is best for Pattukkottai?

With April highs of about 35°C and 66% 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 Pattukkottai?

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 Pattukkottai?

It can be, if the crop, the structure and the buyers match. In Pattukkottai, 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.
