Ensuring adequate nodulation starts with choosing the correct inoculant, keeping it alive prior to seeding and getting good coverage or placement. But what happens if, for any number of reasons, your pulse crop ends up with less than great nodules? What if you’ve got nodules that never pink up or seem to die off? In… Read More
The pea leaf weevil can cause devastating economic losses to both peas and faba beans. Though the adult beetles feed on these crops after overwintering in perennial legumes, it is actually the larvae that cause the greatest damage. Larval feeding occurs on Rhizobium nodules for roughly six weeks. This may limit or completely inhibit nitrogen-fixation… Read More
Results from a seed test could shape several management decisions made at seeding — from fine-tuning the seeding rate to determining the viability of the seed lot for seed at all. Though damaged seeds and vigour issues can be assessed, arguably the biggest factor for consideration in seed test results is the type and level… Read More
Let’s say the planning stages go like this: crop rotation, variety selection, seed testing, determine seeding rate and so on. If you’re a farmer who doesn’t typically test seed or who may be thinking of skipping this step in an effort to save on costs, this episode of the Pulse School is for you. In… Read More
With good lodging resistance, early seeding and marketing flexibility, it’s no wonder faba bean acres continue to rise in Alberta. And with harvest nearing completion, those faba bean stalks are starting to fall, leaving many a smiling farmer in their wake. “By now a lot of the faba beans have started to come off,” said… Read More
Pulse crops are prime targets for harvest dry-down applications, if only because of their indeterminate growth. Add in some less-than-stellar weed control at times, and a desiccant or pre-harvest application of glyphosate can be a great harvest management tool. There are a few things to keep in mind, however, in order to maintain top yield… Read More
A visual assessment of pulse crops isn’t enough to know how well or poorly your inoculation program worked this year. What’s more, it’s important to track nodulation to ensure enough time to go in with a rescue nitrogen application, if warranted. So how do you know if your pulse crop is fixing enough N? Time… Read More
Which input do you think is the most critical to a pea crop’s success — starter N, inoculant type, fungicide seed treatment or seeding rate? If you guessed seeding rate, you get a gold star, but by how much and what impact, if any, do these other inputs have on maximizing pea yields? Those answers… Read More
Thriving in wet, soggy soils (and thus seldom acknowledged as a problem-pathogen in Canada), aphanomyces is difficult to differentiate from other root rot microorganisms based on symptomology alone. Molecular techniques and identification of spores in the lab are the best means of identification, and as of right now, there is no commercial test available for… Read More
Plant health is affected by a multitude of factors, making identifying problems in a field a daunting task. Nobody is capable of identifying every nutrient deficiency, disease symptom, insect species or weed present. But, anyone involved in production should clearly understand the ins and outs of scouting, and what you’ll need in order to ask… Read More
Ascochyta blight is a disease caused by three species of fungi, which are very difficult, if not impossible, to differentiate in the field. Fortunately, diagnosis of a specific pathogen causing ascochyta symptoms is not usually necessary, as control measures are very often the same. Out scouting? Look for purple-brown lesions on the stem, tendrils and… Read More
Applying fungicides to pulses early is crucial, particularly with polycyclic diseases which can spread through the canopy quickly. Downy mildew is one of these polycyclic diseases, but it’s trickier than most to control due to a few factors, says Kan-Fa Chang, research scientist with Alberta Agriculture and Rural Development. Chang says limited fungicide options makes in-crop… Read More
Farmers who had included pulses in their initial crop rotations for 2013 are likely to rewarded for sticking with the crop thanks to continued big demand and lofty prices for most crop types. That’s according to Chuck Penner, owner of LeftField Commodity Research, who spoke with RealAgriculture.com’s Shaun Haney in this episode of the Pulse… Read More
Does your farm have the cleavers? In this episode of the Pulse School, Ken Sapsford, research assistant at the University of Saskatchewan, explains issues surrounding the abundance of cleavers across the prairies. With the shift towards no-till farming practices, cleavers, which were once considered a summer annual, are now overwintering, particularly in the presence of… Read More
We all know that pulling a roller behind the tractor in wet conditions is akin to rolling dough without flour, with one key difference: you likely never have to park your embarrassing, dough-covered rolling pin beside the highway for all to see. Conversely, in dry conditions, a roller can actually pulverize the soil, increasing the… Read More
