Advantages of protected cultivation in Chhapra
1
આખું વર્ષ પાક
A polyhouse stretches the season: in Chhapra cucumber can be grown for about 9 months a year under cover, longer than in the open field.
2
વધુ સારું ઉત્પાદન અને ભાવ
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
ઓછું પાણી
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 294 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.

Which polyhouse suits Chhapra?
For polyhouse farming in Chhapra, the structure decides which months you can crop and what it costs to run. The heat in Chhapra comes with dry air. In April to June, average highs reach 41°C while average humidity is only about 38%. 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 294 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank. Sunlight peaks in April at about 6.5 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 Chhapra
Based on Chhapra's climate, the crops with the longest growing windows are cucumber (9 months), chilli pepper (8 months) and capsicum (7 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Chhapra.

Polyhouse farming in Chhapra: FAQs
Can a polyhouse farm run all year in Chhapra?
Yes, with the right structure. For Chhapra 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 Chhapra?
With May highs of about 41°C and 35% 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 Chhapra?
Going by the monthly climate, cucumber, chilli pepper and capsicum have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Chhapra?
It can be, if the crop, the structure and the buyers match. In Chhapra, 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 Chhapra?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,170 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.
