Planning polyhouse farming in Rajula? Rajula is a small town in Amreli district, Gujarat, home to about 38,000 people (GeoNames)[1][2], about 250 km from Ahmedabad. This guide works from Rajula'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 Rajula
April is the hottest month in Rajula, with average daily highs of about 38°C. January has the coolest nights, averaging 15°C.[3] The area gets about 850 mm of rain a year, most of it in June to September, peaking in July at about 295 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling. Rajula sits about 41 m above sea level.[2] On the Köppen–Geiger climate map, Rajula falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Rajula
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Rajula, 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
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 295 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 (July to September), 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 Rajula?
For polyhouse farming in Rajula, the structure decides which months you can crop and what it costs to run. Average highs stay at 33°C or more in March to June, with moderate humidity of about 55%. In that dry air, wet pads can bring a 38°C April 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. Capsicum, cucumber and tomato do well in a naturally ventilated polyhouse with a shade screen. If you want one structure, decide by crop: greens all year point to Fan & Pad; vine crops point to a naturally ventilated house.
Plan for heavy rain in July (about 295 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 7.3 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 October to February, when it is mild and fairly dry.
Crops for Rajula
Based on Rajula's climate, the crops with the longest growing windows are cucumber (all year), chilli pepper (all year) and brinjal (all year). Cucumber fits all year with Fan & Pad cooling. Strawberry is hard to time here, so we would leave it out of the first season. These are the crops we would plan first for polyhouse farming in Rajula.

₹7,198Spending per person per month, urban Gujarat, 2023–24[6]
250 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 Rajula 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 250 km away.

Polyhouse farming in Rajula: FAQs
Can a polyhouse farm run all year in Rajula?
Yes, with the right structure. For Rajula we would plan Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops. Even then, lettuce is hard to grow in April to August, so plan another crop for those months.
Which polyhouse is best for Rajula?
With April highs of about 38°C and 48% average humidity in that month, we would start with Fan & Pad cooling for leafy greens and a naturally ventilated polyhouse for vine crops.
Which crops should I grow in a polyhouse in Rajula?
Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Rajula?
It can be, if the crop, the structure and the buyers match. In Rajula, cucumber and chilli pepper 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 Rajula?
Yes. Our nearest site is our Nashik warehouse, about 270 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.
