Canola needs to move back up to 20% moisture and temperatures need to be 15 C or warmer before enzymes to reduce chlorophyll will restart and function effectively. Growers with high green canola in the swath have time to wait, if they choose, to see if these necessary rains come along…

Swath at the best time for the majority of the plants in the field with the least negative impact possible on the rest — the biggest yield with the least losses. Note that waiting, if the calendar allows, is often positive for yield. If late season hail damages pods, then these pods have a higher potential for shattering as they…

Rather than focus on how many blank pods may be present, concentrate on yield assessment by examining the components that contribute to yield (ie. number of plants in a given area, number of pods per plant, number of seeds within the pods). The following equation can be used to estimate yield when seed size has a thousand kernel weight of…

Parts of central Alberta have canola fields that have been written off due to severe hail. However, a fair amount of plant growth remains. Canola silage may be one option. Canola silage (on a dry matter basis) averages 12 to 14% crude protein but can be as high as 16% or more. Total Digestible Nutrients TDN (energy) averages 55% to…

When crops are maturing rapidly in hot conditions, swathing before 50-60% seed color change on the main stem may not give chlorophyll time to clear from immature seed. Some fields may require additional moisture — rain — in order to re-hydrate the seed so chlorophyll can clear. If growers feel they must swath at less than 50-60% seed color change…

The Canadian Grain Commission has a colour guide for elevator graders to follow. Distinctly green is a dark green throughout the whole seed. Light green or greenish yellow seeds – sometimes called 'limes' – are not distinctly green and are not included in the green total…
