Row spacing, seeding depth, seeding rate and trinexapac‐ethyl effects on oat yield and lodging

Lodging can reduce the yield and quality of oats (Avena sativa L.). Root lodging, as opposed to stem is predominant form lodging in oats. Therefore, identifying management practices that enhance root resistance should be prioritized. The objective this study was investigate effect four on oat grain yield, components, quality, observed plant traits contribute resistance. Row spacing seeding depth were tested three cultivars across two environments Ontario, Canada. Seeding rate application growth regulator trinexapac-ethyl (TE) at different nitrogen (N) fertilizer rates two-to-three environments. occurred naturally all environments, with always occurring, sometimes combination lodging. Under high pressure, shallow increased Similarly, greater when pressure high. Reducing row had no but only practice consistently increase yield. TE reduced some especially N increased. plate spread, depth, safety factor minimally affected by studied complex interactions genotype environment. Among measured crop traits, height strongest most consistent relationship
