Planning polyhouse farming in Patan? Patan is a mid-sized city in Patan district, Gujarat, home to about 1.3 lakh people (Census 2011)[1], about 100 km from Ahmedabad. This guide works from Patan'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 Patan
May is the hottest month in Patan, with average daily highs of about 43°C. January has the coolest nights, averaging 11°C.[2] The area gets about 598 mm of rain a year, most of it in July to August, peaking in July at about 206 mm. Average humidity stays at 75% or more in August, which raises the risk of leaf disease and slows evaporative cooling. Patan sits about 76 m above sea level.[1] On the Köppen–Geiger climate map, Patan falls in the hot semi-arid zone (BSh).[3]

Advantages of protected cultivation in Patan
1
Year-round crops
Under cover, capsicum can be grown for 10 months a year in Patan, 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 598 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 Gujarat can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Patan?
For polyhouse farming in Patan, the structure decides which months you can crop and what it costs to run. The heat in Patan comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 38%. In that dry air, wet pads can bring a 43°C May afternoon down to roughly 33°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 December and costs less to run.
Plan for heavy rain in July (about 206 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 7.5 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 November to February and September, when it is mild and fairly dry.
Crops for Patan
Based on Patan's climate, the crops with the longest growing windows are capsicum (10 months), cucumber (10 months) and chilli pepper (10 months). Capsicum fits February to May and July to December with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Patan.

₹7,198Spending per person per month, urban Gujarat, 2023–24[5]
100 kmto Ahmedabad, the nearest metro (straight line)
Urban households in Gujarat spent an average of ₹7,198 per person per month in 2023–24, close to the all-India urban average of ₹7,078.[5] Local demand in Patan 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 100 km away.

Polyhouse farming in Patan: FAQs
Can a polyhouse farm run all year in Patan?
Yes, with the right structure. For Patan 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 Patan?
With May highs of about 43°C and 37% 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 Patan?
Going by the monthly climate, capsicum, cucumber and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Patan?
It can be, if the crop, the structure and the buyers match. In Patan, capsicum 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 Patan?
Yes. Our nearest site is our Nashik warehouse, about 460 km away, and we have built 12 projects in Gujarat.
Is there a subsidy for polyhouse or hydroponic farms in Gujarat?
Yes. Protected cultivation projects in Gujarat 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.
