Advantages of protected cultivation in Ranaghat
1
ఏడాది పొడవునా పంటలు
Under cover, cucumber can be grown for 10 months a year in Ranaghat, 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 342 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 Ranaghat?
For polyhouse farming in Ranaghat, 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 63%. 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 342 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. A nethouse, the lowest-cost option, can grow hardy crops in November to February, when it is mild and fairly dry.
Crops for Ranaghat
Based on Ranaghat'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 Ranaghat.

Polyhouse farming in Ranaghat: FAQs
Can a polyhouse farm run all year in Ranaghat?
Yes, with the right structure. For Ranaghat we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops. Even then, lettuce is hard to grow in April to September, so plan another crop for those months.
Which polyhouse is best for Ranaghat?
With April highs of about 39°C and 56% average humidity in that month, we would start with Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.
Which crops should I grow in a polyhouse in Ranaghat?
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 Ranaghat?
It can be, if the crop, the structure and the buyers match. In Ranaghat, 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.
