Straight combining: environment and timeliness matter more than variety

November 13, 2015

KEY PRACTICE: This study found that most hybrids could be straight combined successfully with minimal harvest losses when harvested in a timely manner under reasonably average environmental conditions. When making a seed decision, balance pod shatter resistance with other selection factors including yield potential, herbicide system, days to maturity and other agronomic factors.

PROJECT TITLE, LEAD RESEARCHER: “Quantifying genetic difference in seed losses due to pod drop and pod shattering in canola,” 2011-15, Chris Holzapfel, Indian Head Agricultural Research Foundation (IHARF) 

GROWER ORGANIZATION FUNDER: SaskCanola


Some varieties are better suited to straight combining than others, but success largely depends on environmental factors and timeliness of harvest.

This four-year, multi-site study aimed to evaluate the resistance of various varieties to environmental pod shatter and pod drop losses. More specifically, it intended to: quantify the frequency and amount of seed losses in straight combined canola across a range of environmental conditions; determine relative resistance to pod shatter and pod drop of varieties recommended for straight combining; and evaluate the environmental seed losses from pod drop versus pod shatter.
