Advantages of protected cultivation in Silchar
1
वर्षभर पिके
Under cover, chilli pepper can be grown for 11 months a year in Silchar, so you can supply buyers every week instead of one open-field season.
2
चांगले उत्पादन आणि भाव
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.

कमी पाणी
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps June's 539 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 (May to December), so you spray less often.

Which polyhouse suits Silchar?
For polyhouse farming in Silchar, the structure decides which months you can crop and what it costs to run. With average highs between 24°C and 33°C through the year, Silchar suits a naturally ventilated polyhouse for most crops. Fan & Pad cooling is rarely needed; spend the budget on good ventilation, insect net and a shade screen. Plan for heavy rain in June (about 539 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 November to March, when it is mild and fairly dry.
Crops for Silchar
Based on Silchar's climate, the crops with the longest growing windows are chilli pepper (11 months), cucumber (9 months) and brinjal (9 months). Chilli pepper fits February to December in a naturally ventilated polyhouse. Lilium and broccoli are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in Silchar.

Polyhouse farming in Silchar: FAQs
Can a polyhouse farm run all year in Silchar?
Yes, with the right structure. For Silchar we would plan a naturally ventilated polyhouse. Even then, lettuce is hard to grow in May to September, so plan another crop for those months.
Which polyhouse is best for Silchar?
With April highs of about 33°C and 72% average humidity in that month, we would start with a naturally ventilated polyhouse.
Which crops should I grow in a polyhouse in Silchar?
Going by the monthly climate, tomato, capsicum and chilli pepper have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Silchar?
It can be, if the crop, the structure and the buyers match. In Silchar, chilli pepper 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.
Does Kryzen build polyhouses in Silchar?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,880 km away, and we have built 2 projects in Assam.
Is there a subsidy for polyhouse or hydroponic farms in Assam?
