New Inoculant Can Boost Yields Up To Eight Per Cent

Prairie field pea and lentil growers will be watching the results of field-scale trials across Western Canada this year, as Becker Underwood introduces a new high-performance inoculant.

Research is showing that Nodulator XL, with a new “highly active” strain of rhizobia, can increase yields in these two crops by up to eight per cent.

Nodulator XL, has received full registration and will be available to farmers this fall, says Ralph deVries, Becker Underwood’s director of marketing.

The new inoculant, which works equally well on both peas and lentils, will be available in self-sticking peat, liquid, and granular formulations. It is a new strain – Strain 1435 – of the Rhizobium leguminosarum biovar viecae, which is the rhizobia found in Nodulator. The original Nodulator is still recommended as an effective product for inoculating chickpeas and dry beans.

“Nodulator XL is a new strain that does a much better job of fixing nitrogen in both peas and lentils,” says deVries. “We have done extensive research trials across Western Canada in support of product registration. Looking at the results on the conservative side, on average it has been shown to increase yields by three to eight per cent over other leading inoculants. It has consistently shown a six per cent yield increase in peas, and a nine per cent yield improvement in lentils.”

Based on five-year price and yield averages, deVries says the three to eight per cent yield improvement range represents $4.99 to $13.30 more per acre with peas and $8.39 to $22.37 more per acre return on lentils.

As a followup to the 172 station- years’ worth of research trials in support of registration, Becker Underwood this year has 13 field-scale trials across Western Canada, says Danielle Fletcher, field agronomist.

“We are working with a number of commercial producers with trials ranging from 10 to 40 acres in size and comparing the performance of Nodulator XL with the original Nodulator and other leading inoculant brands,” she says.

Fletcher points out the convenience for growers to have one inoculant, which is equally effective on both peas and lentils. The company is recommending producers use the same product application rate when using either the self-adhesive peat or liquid formulations of Nodulator XL, however if using the solid core granules, the application rate can be reduced.

Nodulator XL is compatible with the same seed treatments as the original Nodulator. The compatibility charts will be available online at www.nodu starting October 1.

“We are excited to be introducing this new product which is much more effective at fixing nitrogen,” says deVries. “We are a relatively small company, and it takes a lot of work first of all to screen the potential agents and find something that shows promise, and then to carry out the research that proves its effectiveness.
