Advantages of protected cultivation in Rajampet
1
ఏడాది పొడవునా పంటలు
Under cover, capsicum can be grown for the whole year in Rajampet, so you can supply buyers every week instead of one open-field season.
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
Drip irrigation under cover uses less water than flood irrigation, and the roof keeps October's 193 mm of rain off the crop and the soil.
4
Less pesticides
Insect net on vents and doors keeps out most pests, and controlled ventilation helps with leaf disease in the humid months (September to January), so you spray less often.

Which polyhouse suits Rajampet?
For polyhouse farming in Rajampet, the structure decides which months you can crop and what it costs to run. The heat in Rajampet comes with dry air. In April to May, average highs reach 39°C while average humidity is only about 52%. In that dry air, wet pads can bring a 39°C April afternoon down to roughly 33°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 October to January and costs less to run.
Sunlight peaks in April 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 December to February and July, when it is mild and fairly dry.
Crops for Rajampet
Based on Rajampet's climate, the crops with the longest growing windows are capsicum (all year), cucumber (all year) and chilli pepper (all year). Capsicum fits all year with Fan & Pad cooling. Strawberry and lilium are hard to time here, so we would leave them out of the first season. These are the crops we would plan first for polyhouse farming in Rajampet.
