Canola and Dry Edible Bean Seasonal Summary
Canola Seasonal Summary
It was a great season for growing canola in many areas of the province as the weather cooperated from planting through to harvest. Canola acreage in 2015 was about 25,000 acres, which is a small increase from about 22,000 acres in 2014. Acreage in northern parts of the province remained low because of the threat of swede midge.
Timely planting and fast growth early in the season reduced the opportunity for insect damage by flea beetle and swede midge. Both insects could be found in the crop but appeared later than in past years. Swede midge damage was the cause of low yields in the Timiskaming area but the damage was not as severe as in recent years.
Moderate temperatures through the flowering period contributed to high yields, and some farmers had very high yields this season. County yield averages across the province were fairly consistent, ranging from 2100 to 2700 lbs/ac with the exception of Sudbury and Timiskaming areas having an average yield around 1900 lbs/ac. The reported Ontario yield average is at 2341 lbs/ac, an increase of about 7% over last year and about 20% over the 10 year average.
Edible Bean Seasonal Summary
The number of acres planted to white beans was 63,000, similar to 2014. Acres of coloured beans were also relatively high at around 72,000 acres in 2015. Many were able to plant into good soil conditions in late May and early June, but heavy rains during the first week of June left some fields under water. Emergence and final plant stands were a major problem this year. As much as 25% of the edible crop had to be replanted leading to issues with seed availability Frequent showers with heavy downpours made planting a real challenge this year.
Root rot occurred in fields that had standing water, but some farmers reported surprisingly low amounts of root rot given the rains in June. White mould was a problem in specific fields. There were some hot spots attributed to variety, history of white mould and management practices but the environmental conditions this year were not as favourable for white mould as they were in 2014. Bacterial brown spot in adzuki was also more prominent in 2014, and only showed up this season in a few fields in the Lake Scugog area. The damage was not widespread and occurred mostly on later planted beans.
Western Bean Cutworm populations have become established in areas with sandy soils. It is likely that damaged beans are being blown out the back of the combine, so it is difficult to estimate the level of damage.
In general, edible beans planted after the June rain events were higher quality and had higher yields than those planted early. This was partly due to hot and dry conditions during flowering for earlier planted beans but more favourable conditions later on. Poor plant stands also contributed to lower yields in fields hit with hard rains. For most farmers conditions were dry at harvest which made combining relatively easy. Although for some it was overly dry and dew was absent during pulling, causing shattering losses and seed coat quality issues.
Yield results across the province range from disappointing to very high, and even within counties there was a large spread from field to field. Yields reported to date appear to be very comparable to the 10 year average for white and black beans at about 2100 lbs/ac for both. Yields are below average for coloured beans, particularly cranberry and kidney at about 1600 lbs/ac for both. For adzuki and otebo beans the combined yield is around 1450 lbs/ac. The yield results are based on what has been reported to date, and account for about a third of the acreage in each class.
