Planning polyhouse farming in Deoghar? Deoghar is a mid-sized city in Deoghar district, Jharkhand, home to about 2 lakh people (Census 2011)[1], about 270 km from Kolkata. 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 Deoghar
April is the hottest month in Deoghar, with average daily highs of about 39°C.

Advantages of protected cultivation in Deoghar
1
Year-round crops
Under cover, capsicum can be grown for 10 months a year in Deoghar, 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 298 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 Jharkhand can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Deoghar?
For polyhouse farming in Deoghar, the structure decides which months you can crop and what it costs to run. The heat in Deoghar comes with dry air. In April to May, average highs reach 39°C while average humidity is only about 44%. In that dry air, wet pads can bring a 39°C April afternoon down to roughly 29°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 February and August to November and costs less to run.
Plan for heavy rain in July (about 298 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.4 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 November, when it is mild and fairly dry.
Crops for Deoghar
Based on Deoghar'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 Deoghar.

Polyhouse farming in Deoghar: FAQs
Can a polyhouse farm run all year in Deoghar?
Yes, with the right structure. For Deoghar we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to August, so plan another crop for those months.
Which polyhouse is best for Deoghar?
With April highs of about 39°C and 36% 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 Deoghar?
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 Deoghar?
It can be, if the crop, the structure and the buyers match. In Deoghar, 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 Deoghar?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,280 km away, and we have built 2 projects in Jharkhand.
Is there a subsidy for polyhouse or hydroponic farms in Jharkhand?
Yes. Protected cultivation projects in Jharkhand 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.
