Planning polyhouse farming in Dewas? Dewas is a mid-sized city in Madhya Pradesh, home to about 2.9 lakh people (GeoNames)[1][2], about 360 km from Ahmedabad. This guide works from Dewas'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 Dewas
May is the hottest month in Dewas, with average daily highs of about 42°C. January has the coolest nights, averaging 9°C.[3] The area gets about 1,014 mm of rain a year, most of it in June to September, peaking in July at about 333 mm. Average humidity stays at 75% or more in July to September, which raises the risk of leaf disease and slows evaporative cooling. Dewas sits about 535 m above sea level.[2] On the Köppen–Geiger climate map, Dewas falls in the tropical savanna (dry summer) zone (As).[4]

Advantages of protected cultivation in Dewas
1
Year-round crops
Under cover, capsicum can be grown for 10 months a year in Dewas, 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 333 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 Madhya Pradesh can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Dewas?
For polyhouse farming in Dewas, the structure decides which months you can crop and what it costs to run. The heat in Dewas comes with dry air. In April to May, average highs reach 42°C while average humidity is only about 23%. 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 February and July to November and costs less to run.
Plan for heavy rain in July (about 333 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 7.2 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 February and October to December, when it is mild and fairly dry.
Crops for Dewas
Based on Dewas's climate, the crops with the longest growing windows are capsicum (10 months), tomato (10 months) and chilli pepper (10 months). Capsicum fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Dewas.

₹5,589Spending per person per month, urban Madhya Pradesh, 2023–24[6]
360 kmto Ahmedabad, the nearest metro (straight line)
Urban households in Madhya Pradesh spent an average of ₹5,589 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Dewas is large enough for steady local sales to restaurants, hotels and fruit-and-vegetable retailers. Start with a farm size that matches the orders you can confirm. Indore, about 40 km away, is the nearest larger market on our list.

Polyhouse farming in Dewas: FAQs
Can a polyhouse farm run all year in Dewas?
Yes, with the right structure. For Dewas we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to June, so plan another crop for those months.
Which polyhouse is best for Dewas?
With May highs of about 42°C and 26% 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 Dewas?
Going by the monthly climate, capsicum, tomato and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Dewas?
It can be, if the crop, the structure and the buyers match. In Dewas, capsicum and tomato 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 Dewas?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 350 km away, and we have built 8 projects in Madhya Pradesh.
Is there a subsidy for polyhouse or hydroponic farms in Madhya Pradesh?
Yes. Protected cultivation projects in Madhya Pradesh 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.
