Planning polyhouse farming in Bhabua? Bhabua is a town in Bihar, home to about 50,000 people (GeoNames)[1][2], about 560 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 Bhabua
May is the hottest month in Bhabua, with average daily highs of about 43°C. January has the coolest nights, averaging 9°C.[3] The area gets about 912 mm of rain a year, most of it in June to September, peaking in July at about 265 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling. Bhabua sits about 75 m above sea level.[2] On the Köppen–Geiger climate map, Bhabua falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Bhabua
1
Year-round crops
A polyhouse stretches the season: in Bhabua cucumber can be grown for about 9 months a year under cover, longer than in the open field.
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 265 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 September), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Bihar can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Bhabua?
For polyhouse farming in Bhabua, the structure decides which months you can crop and what it costs to run. The heat in Bhabua comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 33%. In that dry air, wet pads can bring a 43°C May 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 265 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May 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 February and October to November, when it is mild and fairly dry.
Crops for Bhabua
Based on Bhabua's climate, the crops with the longest growing windows are cucumber (9 months), capsicum (8 months) and tomato (8 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Bhabua.

₹5,165Spending per person per month, urban Bihar, 2023–24[6]
560 kmto Kolkata, the nearest metro (straight line)
Urban households in Bihar spent an average of ₹5,165 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Local demand in Bhabua may be small for exotic greens, so plan where the rest of the harvest goes. Varanasi, about 70 km away, is the nearest larger market on our list.

Polyhouse farming in Bhabua: FAQs
Can a polyhouse farm run all year in Bhabua?
Yes, with the right structure. For Bhabua we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to August, so plan another crop for those months.
Which polyhouse is best for Bhabua?
With May highs of about 43°C and 28% 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 Bhabua?
Going by the monthly climate, cucumber, capsicum and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Bhabua?
It can be, if the crop, the structure and the buyers match. In Bhabua, cucumber and capsicum 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 Bhabua?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,020 km away, and we have built 2 projects in Bihar.
Is there a subsidy for polyhouse or hydroponic farms in Bihar?
Yes. Protected cultivation projects in Bihar can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department. Check the current rate and area limit when you apply.
