Know Your Colours: Understand Distinctly Green and Heated Grading Factors

Tags:
Canola

DISTINCTLY GREEN AND HEATED SEEDS ARE TWO OF THE MOST COMMON DOWNGRADING FACTORS FOR CANOLA.

Understanding the tools and process used to assess distinctly green and heated seeds can help with harvest timing and storage. With the grading process largely visual, the guides are the appropriate tools to consistently assess these grading factors.

Meeting grade tolerances is key to ensuring canola oil’s high quality. High levels of green seed impact the colour and taste and cause the oil to go rancid faster. Distinctly green is the close proxy for chlorophyll content. Heated seed has a similar effect reducing the seed’s usability…

Rates of seeding and fertilizer effects on Canola and Barley

Barley,Canola

Seeding and nitrogen rates can influence crop establishment, seed yield and seed protein level. Optimizing these factors had also demonstrated enhanced crop competitiveness to weeds.

For barley, a plant population of 22 plants/ft² is generally considered the optimum for weed management and yield. The change in grain protein content of barley seeds influences malt quality. The optimum level of protein for malting barley is between 9.5 and 11.5 per cent.

For canola, plant population in a range of 7 to 17 plants/ft² normally had very little effect on the final yield. Also, over this wide range the crop competes very well with weeds. However, differences in days to maturity may be negatively affected and the effect on maturity may be more pronounced in the weather conditions of northern Peace region.

Agronomic value of canola seed quality in northern Peace region

Tags:
Canola

The Peace River region of Alberta offers most challenging conditions for canola stand establishment in Western Canada. Only 20 to 40% of B. rapa (polish canola) and 25 to 30% of B. napus (Argentine canola) seeds can be expected to produce plants in the Peace region compared to 40 to 60% in most areas of western Canada (Canola Growers Manual). Low organic matter soils of the Peace region are prone to crusting and short growing season forces producers to seed canola in cold soils. Therefore, this area offers ideal conditions for assessing the effects of differences in seed quality on the establishment and yield of canola under field conditions.
