Advantages of protected cultivation in Sherghati
1
Year-round crops
A polyhouse stretches the season: in Sherghati tomato 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 297 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 October), 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 Sherghati?
For polyhouse farming in Sherghati, the structure decides which months you can crop and what it costs to run. The heat in Sherghati comes with dry air. In April to June, average highs reach 41°C while average humidity is only about 38%. In that dry air, wet pads can bring a 41°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 297 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.7 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 to March and October to November, when it is mild and fairly dry.
Crops for Sherghati
Based on Sherghati's climate, the crops with the longest growing windows are tomato (9 months), cucumber (9 months) and chilli pepper (9 months). Tomato fits February to April and July to December with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Sherghati.

₹5,165Spending per person per month, urban Bihar, 2023–24[6]
430 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 Sherghati may be small for exotic greens, so plan where the rest of the harvest goes. Gaya, about 30 km away, is the nearest larger market on our list.

Polyhouse farming in Sherghati: FAQs
Can a polyhouse farm run all year in Sherghati?
Yes, with the right structure. For Sherghati 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 Sherghati?
With May highs of about 41°C and 34% 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 Sherghati?
Going by the monthly climate, tomato, cucumber and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Sherghati?
It can be, if the crop, the structure and the buyers match. In Sherghati, tomato and cucumber 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 Sherghati?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,100 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.
