Advantages of protected cultivation in Rohtak
1
Year-round crops
A polyhouse stretches the season: in Rohtak 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
With only about 687 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.
5
Subsidy eligible
Polyhouse, shade net and nethouse projects in Haryana can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]
Which polyhouse suits Rohtak?
For polyhouse farming in Rohtak, the structure decides which months you can crop and what it costs to run. The heat in Rohtak comes with dry air. In April to June, average highs reach 43°C while average humidity is only about 28%. In that dry air, wet pads can bring a 43°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 November and costs less to run.
Sunlight peaks in May at about 6.8 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 Rohtak
Based on Rohtak'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 Rohtak.
