Advantages of protected cultivation in Rasra
1
ವರ್ಷವಿಡೀ ಬೆಳೆಗಳು
A polyhouse stretches the season: in Rasra cucumber can be grown for about 8 months a year under cover, longer than in the open field.
2
ಉತ್ತಮ ಇಳುವರಿ ಮತ್ತು ಬೆಲೆ
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
ಕಡಿಮೆ ನೀರು
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 285 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.

Polyhouse, shade net and nethouse projects in Uttar Pradesh can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Rasra?
For polyhouse farming in Rasra, the structure decides which months you can crop and what it costs to run. The heat in Rasra comes with dry air. In April to June, average highs reach 42°C while average humidity is only about 34%. In that dry air, wet pads can bring a 42°C May afternoon down to roughly 30°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 October to November and costs less to run.
Plan for heavy rain in July (about 285 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 Rasra
Based on Rasra's climate, the crops with the longest growing windows are cucumber (8 months), chilli pepper (7 months) and brinjal (7 months). Cucumber fits March to May and July to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Rasra.

₹5,474Spending per person per month, urban Uttar Pradesh, 2023–24[6]
580 kmto Kolkata, the nearest metro (straight line)
Urban households in Uttar Pradesh spent an average of ₹5,474 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Local demand in Rasra may be small for exotic greens, so plan where the rest of the harvest goes. Mau, about 30 km away, is the nearest larger market on our list.

Polyhouse farming in Rasra: FAQs
Can a polyhouse farm run all year in Rasra?
Yes, with the right structure. For Rasra we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to September, so plan another crop for those months.
Which polyhouse is best for Rasra?
With May highs of about 42°C and 30% 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 Rasra?
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 Rasra?
It can be, if the crop, the structure and the buyers match. In Rasra, 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 Rasra?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,100 km away, and we have built 6 projects in Uttar Pradesh.
Is there a subsidy for polyhouse or hydroponic farms in Uttar Pradesh?
Yes. Protected cultivation projects in Uttar Pradesh 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.
