Planning polyhouse farming in Nanjangud? Nanjangud is a town in Mysuru district, Karnataka, home to about 51,000 people (GeoNames)[1][2], about 140 km from Bengaluru. We have used the monthly climate for Nanjangud 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 Nanjangud

March is the hottest month in Nanjangud, with average daily highs of about 35°C. January has the coolest nights, averaging 14°C.[3] The area gets about 887 mm of rain a year, most of it in May to October, peaking in October at about 142 mm. Average humidity stays at 75% or more in June to November, which raises the risk of leaf disease and slows evaporative cooling. Nanjangud sits about 656 m above sea level.[2] On the Köppen–Geiger climate map, Nanjangud falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Nanjangud

  • Year-round crops

    Under cover, cucumber can be grown for 10 months a year in Nanjangud, 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 October's 142 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 (June to November), so you spray less often.

  • Subsidy eligible

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

Which polyhouse suits Nanjangud?

For polyhouse farming in Nanjangud, the structure decides which months you can crop and what it costs to run. With average highs between 27°C and 35°C through the year, Nanjangud 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. Sunlight peaks in March at about 6.6 kWh per m² a day, so add a shade screen for leafy greens in the brightest months.

Protected structures to compare

A nethouse, the lowest-cost option, can grow hardy crops in November to February, when it is mild and fairly dry.

Crops for Nanjangud

Based on Nanjangud's climate, the crops with the longest growing windows are cucumber (10 months), chilli pepper (10 months) and brinjal (10 months). Cucumber fits May to February in a naturally ventilated polyhouse. Lilium and carnation 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 Nanjangud.
