Planning polyhouse farming in Kota? Kota is a city of about 10 lakh people (GeoNames) in Kota district, Rajasthan[1][2], about 410 km from Delhi. We have used the monthly climate for Kota to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.
Climate for polyhouse farming in Kota
May is the hottest month in Kota, with average daily highs of about 43°C. January has the coolest nights, averaging 8°C.[3] The area gets about 761 mm of rain a year, most of it in July to September, peaking in August at about 262 mm. Average humidity stays at 75% or more in August to September, which raises the risk of leaf disease and slows evaporative cooling. Kota sits about 271 m above sea level.[2] On the Köppen–Geiger climate map, Kota falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Kota
1
Year-round crops
A polyhouse stretches the season: in Kota tomato 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
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps August's 262 mm of rain off the crop and the soil.
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 to September), 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 Kota?
For polyhouse farming in Kota, the structure decides which months you can crop and what it costs to run. The heat in Kota comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 29%. In that dry air, wet pads can bring a 43°C May afternoon down to roughly 30°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 August and November and costs less to run.
Plan for heavy rain in August (about 262 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 and October to November, when it is mild and fairly dry.
Crops for Kota
Based on Kota's climate, the crops with the longest growing windows are tomato (9 months), cucumber (9 months) and lettuce (9 months). Tomato fits February to April and July to December with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Kota.

₹6,640Spending per person per month, urban Rajasthan, 2023–24[6]
410 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] A city of this size has hotels, restaurants, modern retail and quick-commerce stores within its own limits, so most harvests can be sold locally. Line up two or three buyers before planting and agree on grade and delivery days.

Polyhouse farming in Kota: FAQs
Can a polyhouse farm run all year in Kota?
Yes, with the right structure. For Kota 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 Kota?
With May highs of about 43°C and 23% 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 Kota?
Going by the monthly climate, tomato, cucumber and lettuce have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Kota?
It can be, if the crop, the structure and the buyers match. In Kota, tomato and cucumber 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 Kota?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 590 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.
