Planning polyhouse farming in Nirmal? Nirmal is a town in Nirmal district, Telangana, home to about 88,000 people (Census 2011)[1], about 190 km from Hyderabad. We have used the monthly climate for Nirmal to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.
Climate for polyhouse farming in Nirmal
May is the hottest month in Nirmal, with average daily highs of about 42°C. December has the coolest nights, averaging 14°C.[2] The area gets about 875 mm of rain a year, most of it in June to September, peaking in July at about 229 mm. Average humidity stays at 75% or more in July to October, which raises the risk of leaf disease and slows evaporative cooling.

Advantages of protected cultivation in Nirmal
1
Year-round crops
Under cover, cucumber can be grown for the whole year in Nirmal, 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 229 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 Telangana can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Nirmal?
For polyhouse farming in Nirmal, the structure decides which months you can crop and what it costs to run. The heat in Nirmal comes with dry air. In April to May, average highs reach 42°C while average humidity is only about 28%. 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 July to January and costs less to run.
Plan for heavy rain in July (about 229 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in May at about 6.9 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 Nirmal
Based on Nirmal's climate, the crops with the longest growing windows are cucumber (all year), capsicum (11 months) and chilli pepper (11 months). 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 Nirmal.

190 kmto Hyderabad, the nearest metro (straight line)
The Census counted 75,000 people in Nirmal in 2001 and 88,000 in 2011, a rise of 18%. In 1991 it was 58,000.[1] Urban households in Telangana spent an average of ₹9,131 per person per month in 2023–24, above the all-India urban average of ₹7,078.[5] Local demand in Nirmal may be small for exotic greens, so plan where the rest of the harvest goes. Nizamabad, about 50 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Hyderabad is within a day's delivery, about 190 km away.

Polyhouse farming in Nirmal: FAQs
Can a polyhouse farm run all year in Nirmal?
Yes, with the right structure. For Nirmal 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 Nirmal?
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 Nirmal?
Going by the monthly climate, cucumber, capsicum and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Nirmal?
It can be, if the crop, the structure and the buyers match. In Nirmal, cucumber 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 Nirmal?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 330 km away, and we have built 14 projects in Telangana.
Is there a subsidy for polyhouse or hydroponic farms in Telangana?
Yes. Protected cultivation projects in Telangana 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.
