Planning polyhouse farming in Sirohi? Sirohi is a small town in Sirohi district, Rajasthan, home to about 39,000 people (GeoNames)[1][2], about 210 km from Ahmedabad. This guide works from Sirohi's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.
Climate for polyhouse farming in Sirohi
May is the hottest month in Sirohi, with average daily highs of about 41°C. January has the coolest nights, averaging 9°C.[3] The area gets about 573 mm of rain a year, most of it in July to August, peaking in August at about 199 mm. Average humidity stays at 75% or more in August, which raises the risk of leaf disease and slows evaporative cooling. Sirohi sits about 321 m above sea level.[2] On the Köppen–Geiger climate map, Sirohi falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Sirohi
1
Year-round crops
Under cover, capsicum can be grown for 10 months a year in Sirohi, so you can supply buyers every week instead of one open-field season.
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 573 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 Sirohi?
For polyhouse farming in Sirohi, the structure decides which months you can crop and what it costs to run. The heat in Sirohi comes with dry air. In April to June, average highs reach 41°C while average humidity is only about 34%. 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 February and November and costs less to run.
Sunlight peaks in May at about 7.5 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 December, when it is mild and fairly dry.
Crops for Sirohi
Based on Sirohi's climate, the crops with the longest growing windows are capsicum (10 months), tomato (10 months) and chilli pepper (10 months). Capsicum fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Sirohi.

₹6,640Spending per person per month, urban Rajasthan, 2023–24[6]
210 kmto Ahmedabad, 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 Sirohi may be small for exotic greens, so plan where the rest of the harvest goes. For premium vegetable and flower buyers, Ahmedabad is within a day's delivery, about 210 km away.

Polyhouse farming in Sirohi: FAQs
Can a polyhouse farm run all year in Sirohi?
Yes, with the right structure. For Sirohi we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to July, so plan another crop for those months.
Which polyhouse is best for Sirohi?
With May highs of about 41°C and 31% 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 Sirohi?
Going by the monthly climate, capsicum, tomato and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Sirohi?
It can be, if the crop, the structure and the buyers match. In Sirohi, capsicum and tomato 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 Sirohi?
Yes. Our nearest site is our Nashik warehouse, about 550 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.
