Advantages of protected cultivation in Muzaffarpur
1
Year-round crops
A polyhouse stretches the season: in Muzaffarpur cucumber can be grown for about 9 months a year under cover, longer than in the open field.
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 295 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 Bihar can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Muzaffarpur?
For polyhouse farming in Muzaffarpur, the structure decides which months you can crop and what it costs to run. The heat in Muzaffarpur comes with dry air. In April to June, average highs reach 41°C while average humidity is only about 40%. In that dry air, wet pads can bring a 41°C May afternoon down to roughly 31°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 October to November and costs less to run.
Plan for heavy rain in July (about 295 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.3 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 Muzaffarpur
Based on Muzaffarpur's climate, the crops with the longest growing windows are cucumber (9 months), chilli pepper (9 months) and brinjal (8 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Muzaffarpur.

Polyhouse farming in Muzaffarpur: FAQs
Can a polyhouse farm run all year in Muzaffarpur?
Yes, with the right structure. For Muzaffarpur 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 Muzaffarpur?
With May highs of about 41°C and 38% 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 Muzaffarpur?
Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Muzaffarpur?
It can be, if the crop, the structure and the buyers match. In Muzaffarpur, cucumber and chilli pepper 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 Muzaffarpur?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,240 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.
