Planning polyhouse farming in Rajampet? Rajampet is a town in YSR Kadapa district, Andhra Pradesh, home to about 54,000 people (Census 2011)[1], about 170 km from Chennai. We have used the monthly climate for Rajampet to plan a structure, a growing system and a crop calendar, so you can compare them with your own plot and buyers.

Climate for polyhouse farming in Rajampet

April is the hottest month in Rajampet, with average daily highs of about 39°C. January has the coolest nights, averaging 16°C.[2] The area gets about 910 mm of rain a year, most of it in August to November, peaking in October at about 193 mm. Average humidity stays at 75% or more in September to January, which raises the risk of leaf disease and slows evaporative cooling. Rajampet sits about 144 m above sea level.[1] On the Köppen–Geiger climate map, Rajampet falls in the tropical savanna (dry winter) zone (Aw).[3]

Advantages of protected cultivation in Rajampet

  • Year-round crops

    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.

  • 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

    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.

  • 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.

  • Subsidy eligible

    Polyhouse, shade net and nethouse projects in Andhra Pradesh can apply for Mission for Integrated Development of Horticulture (MIDH) assistance through the state horticulture department.[4]

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.

Protected structures to compare

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.

Polyhouse farming in Rajampet: FAQs

Can a polyhouse farm run all year in Rajampet?

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

Which polyhouse is best for Rajampet?

With April highs of about 39°C and 51% 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 Rajampet?

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

Is polyhouse farming profitable in Rajampet?

It can be, if the crop, the structure and the buyers match. In Rajampet, capsicum and cucumber 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.
