Planning polyhouse farming in Manvi? Manvi is a town in Raichur district, Karnataka, home to about 46,000 people (GeoNames)[1][2], about 220 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 Manvi
April is the hottest month in Manvi, with average daily highs of about 40°C. December has the coolest nights, averaging 16°C.[3] The area gets about 612 mm of rain a year. The wettest months are August to September, peaking in September at about 137 mm. Average humidity stays at 75% or more in September to October, which raises the risk of leaf disease and slows evaporative cooling. Manvi sits about 361 m above sea level.[2] On the Köppen–Geiger climate map, Manvi falls in the hot semi-arid zone (BSh).[4]

Advantages of protected cultivation in Manvi
1
Year-round crops
Under cover, capsicum can be grown for the whole year in Manvi, 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 612 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 (September to October), so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Karnataka can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Manvi?
For polyhouse farming in Manvi, the structure decides which months you can crop and what it costs to run. The heat in Manvi comes with dry air. In March to May, average highs reach 40°C while average humidity is only about 37%. In that dry air, wet pads can bring a 40°C April afternoon down to roughly 30°C inside a Fan & Pad polyhouse, cool enough for lettuce and other leafy greens. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from September to December and costs less to run.
Sunlight peaks in April at about 6.8 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 and June to July, when it is mild and fairly dry.
Crops for Manvi
Based on Manvi's climate, the crops with the longest growing windows are capsicum (all year), cucumber (all year) and chilli pepper (all year). Capsicum fits all year with Fan & Pad cooling. Lilium and strawberry are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in Manvi.

₹8,169Spending per person per month, urban Karnataka, 2023–24[6]
220 kmto Hyderabad, the nearest metro (straight line)
Urban households in Karnataka spent an average of ₹8,169 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Manvi may be small for exotic greens, so plan where the rest of the harvest goes. Raichur, about 40 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 220 km away.

Polyhouse farming in Manvi: FAQs
Can a polyhouse farm run all year in Manvi?
Yes, with the right structure. For Manvi we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to May, so plan another crop for those months.
Which polyhouse is best for Manvi?
With April highs of about 40°C and 35% 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 Manvi?
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 Manvi?
It can be, if the crop, the structure and the buyers match. In Manvi, 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 Manvi?
Yes. Our nearest site is our factory and master warehouse at Degaon, Wai (Satara), about 400 km away, and we have built 38 projects in Karnataka.
Is there a subsidy for polyhouse or hydroponic farms in Karnataka?
Yes. Protected cultivation projects in Karnataka 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.
