Abstract
- Agricultural production drill and broadcast seeding are established methods for planting cereals. Broadcast seeding has higher risk due to several factors including poor seed to soil contact, poor fertilizer incorporation, poorly incorporated seed exposed to the elements, and lower yields. The University of Idaho conducted a study in 2016 and 2017 using irrigated winter wheat to determine if broadcasting winter wheat seed with fertilizer was as effective as drilling wheat seed. Results showed there was no statistical difference in yield found between the treatments in 2016 (P=0.49) or 2017 (P=0.15). Greater variability between replications was found within the broadcast treatment versus the drilled treatment for both years. Results do not warrant changing established drill seeding recommendations.
