Advantages of protected cultivation in Dimapur
1
ఏడాది పొడవునా పంటలు
A polyhouse stretches the season: in Dimapur cucumber can be grown for about 8 months a year under cover, longer than in the open field.
2
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.
3
తక్కువ నీరు
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps July's 249 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 (June to November), so you spray less often.

Which polyhouse suits Dimapur?
For polyhouse farming in Dimapur, the structure decides which months you can crop and what it costs to run. In Dimapur the heat comes with humidity: during April to August average humidity is about 76%. Wet pads cool much less in humid air: on a typical May afternoon they would only bring 34°C down to about 31°C. So we usually start with a tall naturally ventilated polyhouse with wide roof vents, insect net and a shade screen. A Fan & Pad polyhouse still makes sense if buyers need lettuce through the hottest months, but expect a smaller temperature drop than in dry inland towns.
Plan for heavy rain in July (about 249 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 to March and October to December, when it is mild and fairly dry.
Crops for Dimapur
Based on Dimapur's climate, the crops with the longest growing windows are cucumber (8 months), chilli pepper (6 months) and tomato (5 months). Cucumber fits March to April and June to November in a naturally ventilated polyhouse. Lilium and orchids 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 Dimapur.

₹8,136Spending per person per month, urban Nagaland, 2023–24[7]
660 kmto Kolkata, the nearest metro (straight line)
Urban households in Nagaland spent an average of ₹8,136 per person per month in 2023–24, above the all-India urban average of ₹7,078.[7] Local demand in Dimapur may be small for exotic greens, so plan where the rest of the harvest goes.

Polyhouse farming in Dimapur: FAQs
Can a polyhouse farm run all year in Dimapur?
Yes, with the right structure. For Dimapur we would plan a tall naturally ventilated polyhouse with wide vents and insect net. Even then, lettuce is hard to grow in May to September, so plan another crop for those months.
Which polyhouse is best for Dimapur?
With May highs of about 34°C and 72% average humidity in that month, we would start with a tall naturally ventilated polyhouse with wide vents and insect net.
Which crops should I grow in a polyhouse in Dimapur?
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 Dimapur?
It can be, if the crop, the structure and the buyers match. In Dimapur, 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 Dimapur?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 2,000 km away, and we have built one project in Nagaland.
Is there a subsidy for polyhouse or hydroponic farms in Nagaland?
Yes. Protected cultivation projects in Nagaland 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.
