Climate for polyhouse farming in Rourkela

Area averages (a grid cell of about 50 km) for 2001–2025, from NASA POWER, centred on Rourkela, adjusted for the town's elevation[4]. Rainfall and night temperatures at your plot can differ, especially near hills and the coast.[2]
Advantages of protected cultivation in Rourkela
1
Year-round crops
Under cover, tomato can be grown for 10 months a year in Rourkela, 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 367 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 Odisha can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Rourkela?
For polyhouse farming in Rourkela, the structure decides which months you can crop and what it costs to run. The heat in Rourkela comes with dry air. In April to May, average highs reach 42°C while average humidity is only about 41%. In that dry air, wet pads can bring a 42°C May afternoon down to roughly 34°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 November and costs less to run.
Plan for heavy rain in July (about 367 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.7 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 Rourkela
Based on Rourkela's climate, the crops with the longest growing windows are tomato (10 months), cucumber (10 months) and chilli pepper (10 months). Tomato fits July to April with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Rourkela.

Polyhouse farming in Rourkela: FAQs
Can a polyhouse farm run all year in Rourkela?
Yes, with the right structure. For Rourkela we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in April to July, so plan another crop for those months.
Which polyhouse is best for Rourkela?
With May highs of about 42°C and 45% 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 Rourkela?
Going by the monthly climate, tomato, cucumber and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Rourkela?
It can be, if the crop, the structure and the buyers match. In Rourkela, tomato 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.
