Advantages of protected cultivation in Naihati
1
ఏడాది పొడవునా పంటలు
Under cover, cucumber can be grown for 10 months a year in Naihati, so you can supply buyers every week instead of one open-field season.
2
మెరుగైన దిగుబడి మరియు ధర
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
తక్కువ నీరు
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 316 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.

Which polyhouse suits Naihati?
For polyhouse farming in Naihati, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in March to June, with moderate humidity of about 62%. In that dry air, wet pads can bring a 39°C April afternoon down to roughly 33°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. Capsicum, cucumber and tomato do well in a naturally ventilated polyhouse with a shade screen. If you want one structure, decide by crop: greens all year point to Fan & Pad; vine crops point to a naturally ventilated house.
Plan for heavy rain in July (about 316 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
Crops for Naihati
Based on Naihati's climate, the crops with the longest growing windows are cucumber (10 months), chilli pepper (10 months) and brinjal (10 months). Cucumber fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Naihati.

Which crops should I grow in a polyhouse in Naihati?
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 Naihati?
It can be, if the crop, the structure and the buyers match. In Naihati, 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.
