Swathing the lentil plot at proper preharvest timing consistently produced a
more desired green lentil sample compared to desiccation with diquat (Table 5.6),
although there was some genotype crossover effect between desiccation and
swathing. There were significant differences among locations for 2005 and 2006.
For both treatments Goodale (later seeding) produced the more desired green
samples than SPG in 2005 while SPG (later seeding) produced the more desirable
samples in 2006 (Table 5.6).
