Advantages of protected cultivation in Rajakhera
1
Year-round crops
A polyhouse stretches the season: in Rajakhera cucumber can be grown for about 8 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
With only about 627 mm of rain a year here, drip irrigation under cover saves water: less is lost to evaporation and run-off than in the open field.
4
Less pesticides
Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (August), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Rajasthan can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Rajakhera?
For polyhouse farming in Rajakhera, the structure decides which months you can crop and what it costs to run. The heat in Rajakhera comes with dry air. In April to June, average highs reach 44°C while average humidity is only about 26%. In that dry air, wet pads can bring a 44°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 November and costs less to run.
Sunlight peaks in May at about 6.9 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 September to November, when it is mild and fairly dry.
Crops for Rajakhera
Based on Rajakhera's climate, the crops with the longest growing windows are cucumber (8 months), lettuce (7 months) and capsicum (6 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 Rajakhera.

₹6,640Spending per person per month, urban Rajasthan, 2023–24[6]
210 kmto Delhi, the nearest metro (straight line)
Urban households in Rajasthan spent an average of ₹6,640 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Local demand in Rajakhera may be small for exotic greens, so plan where the rest of the harvest goes. Agra, about 30 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Delhi is within a day's delivery, about 210 km away.

Polyhouse farming in Rajakhera: FAQs
Can a polyhouse farm run all year in Rajakhera?
Yes, with the right structure. For Rajakhera 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 Rajakhera?
With May highs of about 44°C and 21% 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 Rajakhera?
Going by the monthly climate, cucumber, lettuce and capsicum have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Rajakhera?
It can be, if the crop, the structure and the buyers match. In Rajakhera, cucumber and lettuce 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 Rajakhera?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 830 km away, and we have built 6 projects in Rajasthan.
Is there a subsidy for polyhouse or hydroponic farms in Rajasthan?
Yes. Protected cultivation projects in Rajasthan 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.
