Planning polyhouse farming in Raghunathganj? Raghunathganj is a town in Murshidabad district, West Bengal[1], about 210 km from Kolkata. Below we use the town's monthly temperatures, humidity and rainfall to work out which structure fits, which crops to grow and in which months, before you spend on construction.
Climate for polyhouse farming in Raghunathganj
April is the hottest month in Raghunathganj, with average daily highs of about 39°C.

Advantages of protected cultivation in Raghunathganj
1
Year-round crops
Under cover, cucumber can be grown for 10 months a year in Raghunathganj, 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 July's 267 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 (July to November), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in West Bengal can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Raghunathganj?
For polyhouse farming in Raghunathganj, the structure decides which months you can crop and what it costs to run. The heat in Raghunathganj comes with dry air. In April to May, average highs reach 39°C while average humidity is only about 51%. In that dry air, wet pads can bring a 39°C April afternoon down to roughly 31°C inside a Fan & Pad polyhouse, which keeps herbs and vine crops going; lettuce will still struggle in the hottest weeks. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from February and September to November and costs less to run.
Plan for heavy rain in July (about 267 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.
Crops for Raghunathganj
Based on Raghunathganj'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 Raghunathganj.

Polyhouse farming in Raghunathganj: FAQs
Can a polyhouse farm run all year in Raghunathganj?
Yes, with the right structure. For Raghunathganj we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to September, so plan another crop for those months.
Which polyhouse is best for Raghunathganj?
With April highs of about 39°C and 44% average humidity in that month, we would start with a Fan & Pad polyhouse for leafy greens.
Which crops should I grow in a polyhouse in Raghunathganj?
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 Raghunathganj?
It can be, if the crop, the structure and the buyers match. In Raghunathganj, 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.
Does Kryzen build polyhouses in Raghunathganj?
