Planning polyhouse farming in Puducherry? Puducherry is a large city in Puducherry, home to about 6.6 lakh people (GeoNames)[1][2], about 140 km from Chennai. We have used the monthly climate for Puducherry to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.

Climate for polyhouse farming in Puducherry

May is the hottest month in Puducherry, with average daily highs of about 33°C. January has the coolest nights, averaging 23°C.[3] The area gets about 1,153 mm of rain a year, most of it in August to December, peaking in November at about 273 mm. Average humidity stays at 75% or more in September to February, which raises the risk of leaf disease and slows evaporative cooling. Puducherry sits about 3 m above sea level.[2] On the Köppen–Geiger climate map, Puducherry falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Puducherry

  • Year-round crops

    Under cover, cucumber can be grown for the whole year in Puducherry, so you can supply buyers every week instead of one open-field season.

  • 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 273 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 (September to February), so you spray less often.

  • Subsidy eligible

    Polyhouse, shade net and nethouse projects in Puducherry can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]

Which polyhouse suits Puducherry?

For polyhouse farming in Puducherry, the structure decides which months you can crop and what it costs to run. With average highs between 27°C and 33°C through the year, Puducherry 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 273 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.

Protected structures to compare

Sunlight peaks in April 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 January to July, when it is mild and fairly dry.

Crops for Puducherry

Based on Puducherry's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (11 months) and brinjal (11 months). 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 Puducherry.
