Advantages of protected cultivation in Nabha
1
Year-round crops
A polyhouse stretches the season: in Nabha cucumber can be grown for about 8 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 183 mm of rain off the crop and the soil.
4
Less pesticides
Insect net on vents and doors keeps out most pests, so you spray less often.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Punjab can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[5]
Which polyhouse suits Nabha?
For polyhouse farming in Nabha, the structure decides which months you can crop and what it costs to run. The heat in Nabha comes with dry air. In May to June, average highs reach 42°C while average humidity is only about 29%. In that dry air, wet pads can bring a 42°C May afternoon down to roughly 30°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 March and November and costs less to run.
Sunlight peaks in May at about 7.3 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 March and October to November, when it is mild and fairly dry.
Crops for Nabha
Based on Nabha's climate, the crops with the longest growing windows are cucumber (8 months), chilli pepper (7 months) and lettuce (7 months). Cucumber fits March to October with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Nabha.

₹7,383Spending per person per month, urban Punjab, 2023–24[6]
220 kmto Delhi, the nearest metro (straight line)
Urban households in Punjab spent an average of ₹7,383 per person per month in 2023–24, above the all-India urban average of ₹7,078.[6] Local demand in Nabha may be small for exotic greens, so plan where the rest of the harvest goes. Patiala, about 20 km away, is the nearest larger market on our list. For premium vegetable and flower buyers, Delhi is within a day's delivery, about 220 km away.

Polyhouse farming in Nabha: FAQs
Can a polyhouse farm run all year in Nabha?
Yes, with the right structure. For Nabha 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 Nabha?
With May highs of about 42°C and 23% 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 Nabha?
Going by the monthly climate, cucumber, chilli pepper and lettuce have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Nabha?
It can be, if the crop, the structure and the buyers match. In Nabha, 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 Nabha?
Yes. Our nearest site is our Chhatrapati Sambhajinagar warehouse, about 1,170 km away, and we have built 4 projects in Punjab.
Is there a subsidy for polyhouse or hydroponic farms in Punjab?
Yes. Protected cultivation projects in Punjab 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.
