Advantages of protected cultivation in Nanjangud
1
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.
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 142 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 (June to November), so you spray less often.
5
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.
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.
