Planning polyhouse farming in Sambhar? Sambhar is a small town in Jaipur district, Rajasthan, home to about 23,000 people (GeoNames)[1][2], about 270 km from Delhi. This guide works from Sambhar's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.

Advantages of protected cultivation in Sambhar
1
Year-round crops
A polyhouse stretches the season: in Sambhar 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
With only about 487 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, 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 Sambhar?
For polyhouse farming in Sambhar, the structure decides which months you can crop and what it costs to run. The heat in Sambhar comes with dry air. In April to June, average highs reach 41°C while average humidity is only about 28%. In that dry air, wet pads can bring a 41°C May afternoon down to roughly 30°C inside a Fan & Pad polyhouse, cool enough for lettuce and other leafy greens. 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 7.2 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 March and October to November, when it is mild and fairly dry.
Crops for Sambhar
Based on Sambhar's climate, the crops with the longest growing windows are cucumber (9 months), chilli pepper (8 months) and brinjal (8 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Sambhar.

₹6,640Spending per person per month, urban Rajasthan, 2023–24[6]
270 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 Sambhar may be small for exotic greens, so plan where the rest of the harvest goes. Jaipur, about 60 km away, is the nearest larger market on our list.

Polyhouse farming in Sambhar: FAQs
Can a polyhouse farm run all year in Sambhar?
Yes, with the right structure. For Sambhar 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 Sambhar?
With May highs of about 41°C and 24% 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 Sambhar?
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 Sambhar?
It can be, if the crop, the structure and the buyers match. In Sambhar, 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 Sambhar?
Yes. Our nearest site is our Nashik warehouse, about 780 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.
