Site Information: The site is located in East Chilliwack. The site has a Fairfield series soil, described as gleyed eluviated melanic brunisol, imperfectly drained and derived from medium and some moderately fine-textured, stone-free, Fraser Valley floodplain deposits.
Design: Randomized complete block design with four replicates.
Plot Size: 4′ by 20′
Harvest Area: 2′ by 20′
Seeding: Broadcast seeded
Fertilizer: Fertilizer was applied to plots prior to cuts 1, 2, 3 and 4, at 100, 75, 50 and 50 kg N ha-1 respectively.
Weed Control: Dyvel was applied to the plots in July.
Irrigation: The plots received no irrigation.
NOTE: In September, weeds had overtaken the Tetrylyte II and PSGG-9-04 plots. The hot, dry conditions of the late summer seemed to particularly negatively affect on these cultivars.
