Planning polyhouse farming in Tonk? Tonk is a mid-sized city in Tonk district, Rajasthan, home to about 1.7 lakh people (Census 2011)[1], about 310 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 Tonk
May is the hottest month in Tonk, with average daily highs of about 43°C. January has the coolest nights, averaging 7°C.[2] The area gets about 611 mm of rain a year, most of it in July to August, peaking in August at about 204 mm. Average humidity stays at 75% or more in August, which raises the risk of leaf disease and slows evaporative cooling. Tonk sits about 289 m above sea level.[1] On the Köppen–Geiger climate map, Tonk falls in the hot semi-arid zone (BSh).[3]

Advantages of protected cultivation in Tonk
1
Year-round crops
A polyhouse stretches the season: in Tonk 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 611 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.[4]
Which polyhouse suits Tonk?
For polyhouse farming in Tonk, the structure decides which months you can crop and what it costs to run. The heat in Tonk comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 27%. 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.
Plan for heavy rain in August (about 204 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. 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 February to March and September to November, when it is mild and fairly dry.
Crops for Tonk
Based on Tonk's climate, the crops with the longest growing windows are cucumber (9 months), capsicum (7 months) and tomato (7 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Tonk.

₹6,640Spending per person per month, urban Rajasthan, 2023–24[5]
310 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.[5] Tonk 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 Tonk: FAQs
Can a polyhouse farm run all year in Tonk?
Yes, with the right structure. For Tonk 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 Tonk?
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 Tonk?
Going by the monthly climate, cucumber, capsicum and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Tonk?
It can be, if the crop, the structure and the buyers match. In Tonk, 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 Tonk?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 700 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.
