Advantages of protected cultivation in Alwar
1
ఏడాది పొడవునా పంటలు
A polyhouse stretches the season: in Alwar 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
With only about 580 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.
4
Less pesticides
Insect net on vents and doors keeps out most pests, so you spray less often.

Which polyhouse suits Alwar?
For polyhouse farming in Alwar, the structure decides which months you can crop and what it costs to run. The heat in Alwar comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 27%. In that dry air, wet pads can bring a 43°C May afternoon down to roughly 31°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 November and costs less to run.
Sunlight peaks in May at about 6.7 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 Alwar
Based on Alwar's climate, the crops with the longest growing windows are cucumber (8 months), lettuce (7 months) and capsicum (6 months). Cucumber fits March to May and July to November with Fan & Pad cooling. These are the crops we would plan first for polyhouse farming in Alwar.

Which crops should I grow in a polyhouse in Alwar?
Going by the monthly climate, cucumber, lettuce and capsicum have the longest growing windows. Confirm prices and volumes with buyers before you plant.
Is polyhouse farming profitable in Alwar?
It can be, if the crop, the structure and the buyers match. In Alwar, cucumber and lettuce 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.
