In many instances, trellises for viny vegetables are constructed standing erect. This one used for French beans Ayoka at the Simon Groot Research Center (SGRC) in Chiang Mai, Thailand, is slanting.
It has its own advantages. The leaves have a wider exposure to sunlight, and the fruits hang for easy harvesting at the underside of the trellis.
Ayoka is a particularly prolific variety developed by East-West Seed company. It was showcased during the International Field Day at the SGRC on February 4, 2013.
