1999 STEEP III Final Report

RESEARCH PROJECT TITLE:

Developing agronomic practices for direct drilling winter Canola into cereal stubble.

INVESTIGATORS:

Jack Brown, Plant Breeder, University of Idaho, Moscow, Idaho
Don Wysocki, Extension Soil Scientist, Oregon State Univ. CBARC, Pendleton, Oregon
Brown will coordinate trails in Idaho and Wysocki will coordinate trials in Oregon.
Other Team members that will cooperate on this project are Bill Payne, Research Agronomist CBARC, Pendleton, Oregon and Dale Wilkins, Agricultural Engineer and Research Leader, ARS Pendleton.

INTERIM REPORT:

Project started fall of 1999

OBJECTIVES:

1. Compare the performance of disk and shank type drill openers for direct seeding winter canola.
2. Determine the influence of stubble mowing on stand establishment and crop performance.
3. Investigate the effect of placement and rate of starter fertilizer on emergence and performance of winter canola.
4. Screen advanced breeding material with late-planting ability under direct-seeding conditions.

KEY WORDS:

Winter canola, Brassica napus L., Direct seed, Stand establishment

STATEMENT OF PROBLEM:

Agronomic practices for winter canola have been developed for planting on summer fallow. These practices have focused on stand establishment in late August to mid September. This planting option is not possible when planting Canola immediately after a cereal crop. The seedbed usually is too dry at this time. New agronomic recommendations are needed to successfully seed winter Canola into cereal residues.

AGRONOMIC ZONE OF INTEREST:

This research will apply to all agronomic zones where recropping of winter Canola is feasible. We expect that it will be most applicable in agronomic zones 1, 2, 3, and 4.

ABSTRACT OF RESEARCH RESULTS:

This project was just initiated and plots have just been sown this fall. Large-plot experiments were planted on September 1, October 1, and November 1 of 1999 at the Columbia Basin Agricultural Research Center, Pendleton, Oregon. Winter canola was directed drilled into cereal stubble, using two drills (Great Plains, disk drill, and Conserva-Pak shank drill), two fertilizer treatments, and two stubble treatments. Small-plot yield trials of 50 advanced breeding lines and 10 control checks were planted on summer-fallow ground, using double disc drills, and direct-drilled into cereal straw, using a Flexi-coil drill, at locations in Idaho, Washington and Oregon.

RESULTS AND INTERPRETATION:

This project was just initiated and plots have just been sown this fall. Ericka winter Canola was sown in experiments on September 1, October 1 and November 1 of 1999 at the Columbia Basin Agricultural Research Center, Pendleton, Oregon. A randomized complete block experiment (4 reps) of winter Canola will be directed drilled into cereal stubble, using two drills (Great Plains, disk drill, and Conserva-Pak shank drill), two fertilizer treatments no starter and 100 lb/acre 16-20-0-14 two stubble treatments (flail mow and standing). Fifty advanced breeding lines and 10 control checks were planted on summer-fallow ground, using double disc drills, at locations in Idaho, Washington and Oregon between late August to early September. These genotypes were planted in adjacent direct seed trials using a Flexi-coil small-plot direct-seed drill. The summer fallow trials all showed good emergence and plants are already well established. Dry fall weather resulted in very late fall emergence of the direct-seed trials. However, all direct-seed trials planted have good emergence but poor establishment going into the winter. There are no performance or comparative results available at this time.

INTERATION WITH OTHER SCIENTISTS CONDUCTION RELATED ACTIVITY:

This project is complimentary to other cropping system projects currently funded by STEEP. There is communication and interaction with researchers Stephen Guy, Dan Ball, Bill Payne and Bill Schillinger, and growers Bert Hendrickson and Del and Steve Teade. In addition, the PI's on this project are in constant communication
