Planning polyhouse farming in Rawatsar? Rawatsar is a small town in Hanumangarh district, Rajasthan, home to about 35,000 people (GeoNames)[1][2], about 280 km from Delhi. 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 Rawatsar
May is the hottest month in Rawatsar, with average daily highs of about 43°C. January has the coolest nights, averaging 6°C.[3] Rain is scarce: about 364 mm a year. Water for the farm will come from a borewell, well, tanker or municipal supply, so test its salts (EC) and hardness before choosing the system. The air is dry for most of the year (average humidity peaks at 52%), which helps evaporative cooling but raises water use per plant. Rawatsar sits about 176 m above sea level.[2] On the Köppen–Geiger climate map, Rawatsar falls in the hot desert zone (BWh).[4]

Advantages of protected cultivation in Rawatsar
1
Year-round crops
A polyhouse stretches the season: in Rawatsar cucumber can be grown for about 7 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 364 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 Rawatsar?
For polyhouse farming in Rawatsar, the structure decides which months you can crop and what it costs to run. The heat in Rawatsar comes with dry air. In April to August, average highs reach 43°C while average humidity is only about 36%. 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 November and costs less to run.
Sunlight peaks in May at about 6.8 kWh per m² a day, so add a shade screen for leafy greens in the brightest months.
Crops for Rawatsar
Based on Rawatsar's climate, the crops with the longest growing windows are cucumber (7 months), lettuce (7 months) and capsicum (5 months). Cucumber fits March to May and August to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Rawatsar.

₹6,640Spending per person per month, urban Rajasthan, 2023–24[6]
280 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 Rawatsar may be small for exotic greens, so plan where the rest of the harvest goes. Sirsa, about 70 km away, is the nearest larger market on our list.

Polyhouse farming in Rawatsar: FAQs
Can a polyhouse farm run all year in Rawatsar?
Yes, with the right structure. For Rawatsar 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 Rawatsar?
With May highs of about 43°C and 22% 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 Rawatsar?
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 Rawatsar?
It can be, if the crop, the structure and the buyers match. In Rawatsar, 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 Rawatsar?
Yes. Our nearest site is our Nashik warehouse, about 1,030 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.
