File:2011-2012 dryland national winter canola at Yellow Jacket, Colorado - DPLA - bb19a291d0163afb74b48d94f1ba44dc (page 3).jpg

This trial was conducted at CSU's Southwestern Colorado Research Center in RCBD with three replications. Plot size: 6 ft x 30 ft. The seedbed at planting was fairly dry. The first significant rainfall (0.33 in.) after planting occurred on 13-Sept. The fall stand averaged 9.0 on a scale of 0 (no stand) to 10 (excellent stand) but some plots had ratings of 6 and 7. The plot area was weed-free at planting but became infested with weeds, mostly shepherdspurse and prickly lettuce in late winter-early spring, which required hand hoeing since no pre-plant herbicide was applied. Precipitation from rain and snow from planting through harvest maturity was 61% of normal. Only October and February had normal precipitation. Total precipitation from March through June was 0.7 in. or 19% of normal, which negatively impacted seed yield. Average seed yield was 945 lb/acre with a low of 607 and a high of 1311 lb/acre. No irrigation water was applied prior to seeding or throughout the growing season. There was very little pod shattering, which was mostly due to bird feeding, and no lodging.
