Planning polyhouse farming in Ajmer? Ajmer is a large city in Ajmer district, Rajasthan, home to about 5.4 lakh people (Census 2011)[1], about 350 km from Delhi. This guide works from Ajmer's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.

May is the hottest month in Ajmer, with average daily highs of about 41°C. January has the coolest nights, averaging 7°C.[2] Rain is scarce: about 462 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. Ajmer sits about 486 m above sea level.[1] On the Köppen–Geiger climate map, Ajmer falls in the hot desert zone (BWh).[3]

Advantages of protected cultivation in Ajmer
1
Year-round crops
A polyhouse stretches the season: in Ajmer 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 462 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.[4]
Which polyhouse suits Ajmer?
For polyhouse farming in Ajmer, the structure decides which months you can crop and what it costs to run. The heat in Ajmer comes with dry air. In April to June, average highs reach 41°C while average humidity is only about 30%. 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 7.3 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 Ajmer
Based on Ajmer's climate, the crops with the longest growing windows are cucumber (9 months), capsicum (8 months) and chilli pepper (8 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Ajmer.

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.[5] Ajmer is large enough for steady local sales to restaurants, hotels and fruit-and-vegetable retailers. Start with a farm size that matches the orders you can confirm.

Polyhouse farming in Ajmer: FAQs
Can a polyhouse farm run all year in Ajmer?
Yes, with the right structure. For Ajmer 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 Ajmer?
With May highs of about 41°C and 26% 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 Ajmer?
Going by the monthly climate, cucumber, capsicum and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Ajmer?
It can be, if the crop, the structure and the buyers match. In Ajmer, cucumber and capsicum 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 Ajmer?
Yes. Our nearest site is our Nashik warehouse, about 720 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.
