Planning polyhouse farming in Kohima? Kohima is a town in Kohima district, Nagaland, home to about 99,000 people (GeoNames)[1][2], about 680 km from Kolkata. We have used the monthly climate for Kohima to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.

Climate for polyhouse farming in Kohima

June is the hottest month in Kohima, with average daily highs of about 28°C. January has the coolest nights, averaging 5°C.[3] The area gets about 1,242 mm of rain a year, most of it in April to September, peaking in July at about 229 mm. Average humidity stays at 75% or more in June to November, which raises the risk of leaf disease and slows evaporative cooling. Kohima sits about 1,444 m above sea level, so nights run cooler than in the plains around it.[2] On the Köppen–Geiger climate map, Kohima falls in the subtropical highland with dry winters zone (Cwb).[4]

Advantages of protected cultivation in Kohima

  • ఏడాది పొడవునా పంటలు

    Under cover, lettuce can be grown for the whole year in Kohima, 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 229 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 (June to November), so you spray less often.

  • సబ్సిడీకి అర్హం

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

Which polyhouse suits Kohima?

For polyhouse farming in Kohima, the structure decides which months you can crop and what it costs to run. Cold, not heat, sets the limits in Kohima: average lows fall to 5°C in January, and nights stay at 8°C or below in December to February. A naturally ventilated polyhouse with roll-up side curtains traps daytime warmth; close the curtains at night in those months. Summer highs reach about 28°C in June, so roof vents and a shade screen are enough. Fan & Pad cooling is rarely worth its running cost here.

Protected structures to compare

Plan for heavy rain in July (about 229 mm): raise the plinth, size the gutters for that month and keep drains away from the nutrient tank.

Crops for Kohima

Based on Kohima's climate, the crops with the longest growing windows are lettuce (all year), tomato (9 months) and rose (9 months). Lettuce fits all year in a naturally ventilated polyhouse. These are the crops we would plan first for polyhouse farming in Kohima.

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.[6] Local demand in Kohima may be small for exotic greens, so plan where the rest of the harvest goes.

Polyhouse farming in Kohima: FAQs

Can a polyhouse farm run all year in Kohima?

Yes, with the right structure. For Kohima we would plan a naturally ventilated polyhouse with roll-up curtains closed on cold nights.

Which polyhouse is best for Kohima?

With June highs of about 28°C and 80% average humidity in that month, we would start with a naturally ventilated polyhouse with roll-up curtains closed on cold nights.

Which crops should I grow in a polyhouse in Kohima?

Going by the monthly climate, lettuce, tomato and broccoli have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Is polyhouse farming profitable in Kohima?

It can be, if the crop, the structure and the buyers match. In Kohima, lettuce and tomato 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 Kohima?

Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 2,030 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.
