Polyhouse farming in Losal: aerial view of a large protected cultivation farm with polyhouses

Planning polyhouse farming in Losal? Losal is a small town in Sikar district, Rajasthan, home to about 29,000 people (GeoNames)[1][2], about 260 km from Delhi. This guide works from Losal's own monthly climate to suggest the protected structure, the crops to start with, and the months each crop is likely to do well.

Climate for polyhouse farming in Losal

May is the hottest month in Losal, with average daily highs of about 41°C. January has the coolest nights, averaging 7°C.[3] Rain is scarce: about 472 mm a year. Water for the farm will come from a borewell, well, tanker or municipal supply, so test its salts (EC) and hardness before choosing the system. Losal sits about 410 m above sea level.[2] On the Köppen–Geiger climate map, Losal falls in the hot desert zone (BWh).[4]

Advantages of protected cultivation in Losal

  • Year-round crops

    A polyhouse stretches the season: in Losal cucumber can be grown for about 9 months a year under cover, longer than in the open field.

  • 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.

  • Less water

    With only about 472 mm of rain a year here, drip irrigation under cover saves water: less is lost to evaporation and run-off than in the open field.

  • Less pesticides

    Insect net on vents and doors keeps out most pests, so you spray less often.

  • Subsidy eligible

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

Which polyhouse suits Losal?

For polyhouse farming in Losal, the structure decides which months you can crop and what it costs to run. The heat in Losal comes with dry air. In May to June, average highs reach 41°C while average humidity is only about 31%. In that dry air, wet pads can bring a 41°C May afternoon down to roughly 29°C inside a Fan & Pad polyhouse, cool enough for lettuce and other leafy greens. For vine crops such as capsicum and cucumber, a naturally ventilated polyhouse with a shade screen works from November and costs less to run.

Protected structures to compare

Sunlight peaks in May at about 7.2 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 Losal

Based on Losal's climate, the crops with the longest growing windows are cucumber (9 months), chilli pepper (8 months) and brinjal (8 months). Cucumber fits March to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Losal.

Urban households in Rajasthan spent an average of ₹6,640 per person per month in 2023–24, below the all-India urban average of ₹7,078.[6] Local demand in Losal may be small for exotic greens, so plan where the rest of the harvest goes. Sikar, about 30 km away, is the nearest larger market on our list.

Polyhouse farming in Losal: FAQs

Can a polyhouse farm run all year in Losal?

Yes, with the right structure. For Losal we would plan a Fan & Pad polyhouse for leafy greens. Even then, lettuce is hard to grow in May to August, so plan another crop for those months.

Which polyhouse is best for Losal?

With May highs of about 41°C and 24% 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 Losal?

Going by the monthly climate, cucumber, chilli pepper and brinjal have the longest growing windows. Confirm prices and volumes with buyers before you plant.

Is polyhouse farming profitable in Losal?

It can be, if the crop, the structure and the buyers match. In Losal, 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 Losal?

Yes. Our nearest site is our Nashik warehouse, about 830 km away, and we have built 6 projects in Rajasthan.

Is there a subsidy for polyhouse or hydroponic farms in Rajasthan?

Yes. Protected cultivation projects in Rajasthan 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.
