Planning polyhouse farming in Rapar? Rapar is a small town in Kutch district, Gujarat, home to about 28,000 people (GeoNames)[1][2], about 210 km from Ahmedabad. 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 Rapar
May is the hottest month in Rapar, with average daily highs of about 42°C. January has the coolest nights, averaging 10°C.[3] The area gets about 525 mm of rain a year, most of it in July to August, peaking in August at about 177 mm.

Advantages of protected cultivation in Rapar
1
Year-round crops
Under cover, chilli pepper can be grown for 11 months a year in Rapar, 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 525 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.[5]
Which polyhouse suits Rapar?
For polyhouse farming in Rapar, the structure decides which months you can crop and what it costs to run. The heat in Rapar comes with dry air. In April to June, average highs reach 42°C while average humidity is only about 48%. In that dry air, wet pads can bring a 42°C May afternoon down to roughly 34°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.
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 November to February, when it is mild and fairly dry.
Crops for Rapar
Based on Rapar's climate, the crops with the longest growing windows are chilli pepper (11 months), cucumber (10 months) and brinjal (10 months). Chilli pepper fits February to December with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Rapar.

210 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.[6] Local demand in Rapar may be small for exotic greens, so plan where the rest of the harvest goes. Gandhidham, about 80 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Ahmedabad is within a day's delivery, about 210 km away.

Polyhouse farming in Rapar: FAQs
Can a polyhouse farm run all year in Rapar?
Yes, with the right structure. For Rapar we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to September, so plan another crop for those months.
Which polyhouse is best for Rapar?
With May highs of about 42°C and 48% 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 Rapar?
Going by the monthly climate, chilli pepper, cucumber and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Rapar?
It can be, if the crop, the structure and the buyers match. In Rapar, chilli pepper 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 Rapar?
Yes. Our nearest site is our Nashik warehouse, about 510 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.
