Trial garden

The leading trial garden in Europe, according to English horticulturist Noel Kingsbury, is Sichtungsgarten Weihenstephan.

Kingsbury describes it as "a unique institution, with no real equivalent in the English-speaking world".

[1] The Muck Crops Research Station, near Kettleby and Ansnorveldt, in Ontario, Canada, operated by the University of Guelph, tests new species and houses a plant pathology laboratory.

Most trials programs are very formal, with scientific designs including random replicated plots to minimise any risk of bias due to placement of plants.

Vegetables are judged looking for such traits as speed to harvest, total yield, fruit taste, fruit quality, ease of harvest, plant habit, disease, and pest resistance.
