Polyhouse farming in Araria: aerial view of a large protected cultivation farm with polyhouses

Planning polyhouse farming in Araria? Araria is a town in Araria district, Bihar, home to about 79,000 people (GeoNames)[1][2], about 410 km from Kolkata. This guide works from Araria'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 Araria

May is the hottest month in Araria, with average daily highs of about 38°C. January has the coolest nights, averaging 9°C.[3] The area gets about 1,348 mm of rain a year, most of it in May to September, peaking in July at about 357 mm. Average humidity stays at 75% or more in July to October, which raises the risk of leaf disease and slows evaporative cooling. Araria sits about 47 m above sea level.[2] On the Köppen–Geiger climate map, Araria falls in the humid subtropical with dry winters zone (Cwa).[4]

Advantages of protected cultivation in Araria

  • ఏడాది పొడవునా పంటలు

    Under cover, chilli pepper can be grown for 10 months a year in Araria, so you can supply buyers every week instead of one open-field season.

  • మెరుగైన దిగుబడి మరియు ధర

    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.

  • తక్కువ నీరు

    Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 357 mm of rain off the crop and the soil.

  • 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.

  • సబ్సిడీకి అర్హం

    Polyhouse, shade net and nethouse projects in Bihar can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]

Which polyhouse suits Araria?

For polyhouse farming in Araria, the structure decides which months you can crop and what it costs to run. The heat in Araria comes with dry air. In April to May, average highs reach 38°C while average humidity is only about 44%. In that dry air, wet pads can bring a 38°C May afternoon down to roughly 32°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 September to November and costs less to run.

Protected structures to compare

Plan for heavy rain in July (about 357 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. 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 Araria

Based on Araria's climate, the crops with the longest growing windows are chilli pepper (10 months), capsicum (9 months) and cucumber (9 months). Chilli pepper fits February to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Araria.

Polyhouse farming in Araria: FAQs

Can a polyhouse farm run all year in Araria?

Yes, with the right structure. For Araria we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to September, so plan another crop for those months.

Which polyhouse is best for Araria?

With May highs of about 38°C and 51% 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 Araria?

Going by the monthly climate, chilli pepper, capsicum and cucumber have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Is polyhouse farming profitable in Araria?

It can be, if the crop, the structure and the buyers match. In Araria, chilli pepper 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 Araria?

Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,430 km away, and we have built 2 projects in Bihar.

Is there a subsidy for polyhouse or hydroponic farms in Bihar?

Yes. Protected cultivation projects in Bihar 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.
