The development of successful no-till crop production systems has led to th
e practice of applying all the seed and fertilizer in a single field operat
ion. This study was initiated to assist producers in the selection of comme
rcially available bolt-on side banding openers. Field trials were conducted
at 10 locations in Saskatchewan over a 2-yr period (1995 and 1996) to eval
uate the performance of five bolt-on side band openers on the establishment
and yield of spring wheat (Triticum aestivum L.) and canola (Brasica rapa
L.). Trial locations were selected to provide a range of soil and environme
ntal conditions. The openers tested included the Flexi-coil Stealth (TM), D
utch-Vern Eaglebuster (TM) Swede SW470 (TM), GEN 200 and Morris Edge-On (TM
). Fertilizer nitrogen (N) as urea was applied in the side band at rates of
0, 40, 80 and 120 kg N ha(-1) with a side banded starter fertilizer blend
of phosphorus, potassium and sulphur. When properly adjusted for individual
site soil conditions at seeding, no difference was recorded between the si
de band openers tested in the establishment and grain yield of spring wheat
. Averaged across all N rates, three of the five openers showed poor canola
seedling emergence, indicating inadequate seed-fertilizer separation. Howe
ver, the ability of the canola crop to branch and compensate for poor crop
establishment prevented any significant grain yield loss in this study. In
cases where differences between openers were observed, the Flexi-Coil Steal
th (TM) and GEN 200 (TM) openers provided the best crop establishment. Give
n the importance of crop establishment to achieving optimum grain yields, t
he bolt-on side band openers that provided good crop establishment should b
e recommended to producers.
