Soybeans in parts of Western Canada have started to show visual signs of nitrogen deficiency due to poor nodulation and dry conditions. The symptoms are showing up as nitrogen uptake is about to peak, with the crop heading into the critical pod-filling stage. Nodulation failure appears to be more prevalent in fields where soybeans have… Read More
OMAFRA soybean specialist Horst Bohner is back on his tractor and rolling soybeans for a second year as part of a multi-year research trial. The fundamental idea behind the research is to somehow induce a response that will cause the soybean plant to become more bushy and produce more nodes. At meetings this winter, growers… Read More
On the first day of summer how many soybean plants per acre are required to maintain 100 percent yield potential? The answer is simple – 150,000 plants per acre. But there are many management factors to consider when trying to hit that number. In this episode of the RealAgriculture Soybean School, Ontario Ministry of Agriculture, Food… Read More
Strip tillage in corn is growing in popularity in Ontario, but we don’t often see the tillage strategy employed in soybeans. On this episode of RealAgriculture’s Soybean School, AGRIS Co-operative agronomist Dale Cowan takes us to a strip-tilled field, which features twin row, 7.5-inch soybeans planted on 30-inch centres. In the field, Cowan’s bother, Larry… Read More
Summer has officially arrived, and it’s time to get out and assess soybean plant stands. In this episode of RealAgriculture’s Soybean School, we catch up with Ontario Ministry of Agriculture, Food and Rural Affairs soybean specialist Horst Bohner as he surveys plots at a research site in Bornholm, Ontario. As Bohner surveys a stand planted… Read More
Many Ontario farmers will remember when they routinely sprayed soybean crops to control bean leaf beetle. That changed 10 years ago with the introduction of neonicotinoid insecticide seed treatments, which helped suppress populations of the pest in Ontario and many U.S. states. But the pest is mounting a comeback as neonic use continues to decline and… Read More
The introduction of protein price discounts by at least one soybean buyer in Western Canada this past winter has left soybean growers wondering what can be done to ensure Prairie soybeans are high enough in protein content. Unfortunately, there’s no quick or easy management fix, says Dennis Lange, pulse and soybean production specialist with Manitoba… Read More
Many agronomists talk about the importance of multiple modes of action when planning a weed control program. In this episode of RealAgriculture’s Soybean School, Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike Cowbrough shows you why. We catch up with Cowbrough as he surveys a patch of Canada fleabane that has survived… Read More
What’s your strategy when scouting a newly emerged soybean field? When Agromart Group agronomist Steph Kowalski walks into a soybean field this time of year, the first thing she looks to assess is final emergence and population. “It’s important to know how well we got that seed into the ground,” Kowalski tells RealAgriculture’s Bernard Tobin… Read More
By François Tardif Many master gardeners would tell you that to maximize your vegetable yields, rows need to be oriented in a north-south manner. This is supposed to maximize light interception by the crops, which in turn maximizes photosynthesis. In contrast, east-west rows have more shading and this negatively impacts yields. Is the same true… Read More
There are certainly unknowns and risks that come with planting bin-run soybean seed versus certified seed, but one significant piece of information has been confirmed by crop insurance data in Manitoba: older, off-patent varieties don’t have the same yield potential as newer varieties. As Dennis Lange, pulse specialist with Manitoba Agriculture, points out in this… Read More
As planting decisions are finalized, the risk of iron deficiency chlorosis (IDC) is one of the factors soybean growers in Western Canada and the Northern Plains are keeping in mind after unprecedented yellowing due to IDC in many areas last year. A wet 2016 growing season followed by a dry start to 2017, left elevated… Read More
Are we doing enough to reduce the herbicide-resistance weed seedbank on Ontario farms? That’s a question AGRIS Co-operative agronomist Dale Cowan wants farmers in the province to consider when they’re planning their weed control programs for this year. Cowan recently attended the Commodity Classic in Anaheim, California, where he talked with farmers from Mississippi who… Read More
Soybean growers in Western Canada have not yet had to face a soil-borne pest that has hurt yields in other soybean growing regions, but it’s only a matter of time. Soybean cyst nematode (SCN) has steadily spread north along the Red River and has been found in soils on at least two farms near the… Read More
Soybean cyst nematode (SCN) is the crop’s number one yield-robbing pest, and the problem is only going to get worse as the pest continues to breakdown the defence provided by SCN-resistant soybean varieties. It really is a case of the pest becoming “resistant to the resistance,” says Iowa State nematologist Greg Tylka. About 95 percent… Read More
