Planning polyhouse farming in Purna? Purna is a small town in Parbhani district, Maharashtra, home to about 36,000 people (GeoNames)[1][2], about 250 km from Hyderabad. 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 Purna
May is the hottest month in Purna, with average daily highs of about 42°C. December has the coolest nights, averaging 13°C.[3] The area gets about 806 mm of rain a year, most of it in June to September, peaking in July at about 188 mm. Average humidity stays at 75% or more in July to October, which raises the risk of leaf disease and slows evaporative cooling. Purna sits about 384 m above sea level.[2] On the Köppen–Geiger climate map, Purna falls in the tropical savanna (dry winter) zone (Aw).[4]

Advantages of protected cultivation in Purna
1
Year-round crops
Under cover, chilli pepper can be grown for the whole year in Purna, 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 188 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 October), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Maharashtra can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Purna?
For polyhouse farming in Purna, the structure decides which months you can crop and what it costs to run. The heat in Purna comes with dry air. In April to May, average highs reach 42°C while average humidity is only about 27%. In that dry air, wet pads can bring a 42°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 to January and costs less to run.
Sunlight peaks in May at about 7.0 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 January, when it is mild and fairly dry.
Crops for Purna
Based on Purna's climate, the crops with the longest growing windows are chilli pepper (all year), capsicum (11 months) and tomato (11 months). Chilli pepper fits all year with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Purna.

₹7,415Spending per person per month, urban Maharashtra, 2023–24[6]
250 kmto Hyderabad, the nearest metro (straight line)
Urban households in Maharashtra spent an average of ₹7,415 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Purna may be small for exotic greens, so plan where the rest of the harvest goes. Parbhani, about 30 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 250 km away.

Polyhouse farming in Purna: FAQs
Can a polyhouse farm run all year in Purna?
Yes, with the right structure. For Purna we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to June, so plan another crop for those months.
Which polyhouse is best for Purna?
With May highs of about 42°C and 29% 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 Purna?
Going by the monthly climate, chilli pepper, capsicum and tomato have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Purna?
It can be, if the crop, the structure and the buyers match. In Purna, chilli pepper 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 Purna?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 190 km away, and we have built 95 projects in Maharashtra.
Is there a subsidy for polyhouse or hydroponic farms in Maharashtra?
Yes. Protected cultivation projects in Maharashtra 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.
