PGRs may be useful for managing longer-straw varieties and/or crops in fields high in nitrogen.

Shorter straw, higher yield?

Trial assesses plant growth regulators on different varieties at several locations

Reading Time: 4 minutes On paper, it’s an ideal combination — a product which shortens straw but doesn’t reduce yield. But are plant growth regulators (PGRs) a worthwhile investment? That’s being assessed based on ongoing trials in Manitoba. In Canada, the most promising PGR is chlormequat chloride, marketed by EngageAgro under the trade name Manipulator. The product has been […] Read more

AC Foremost red spring wheat at Killam, Alta. The left side represents standard agronomic management while the right side includes standard agronomic management plus 30 pounds of nitrogen per acre applied prior to stem elongation. It also includes applications of plant growth regulator, flag fungicide and head fungicide. The plot was part of a three-year project in Alberta dedicated to identifying yield-maximizing practices in wheat and barley.

Sorting out the stacks

New research in Alberta suggests big yield gains for wheat when combining some agronomic practices — especially dual fungicide applications

Reading Time: 6 minutes Farmers experiment with their agronomic practices all the time. It’s not uncommon to see them “stack” inputs, for instance by combining fertilizer, plant growth regulators (PGRs) and fungicides to see which combinations boost their yields. But until recently, there has been little in the way of small-plot research into the yield potential of stacking agronomic […] Read more


Gibberellins promote cell elongation, which can affect shoots, stems and leaves, increasing the intermodal lengths.

Higher corn yields on the way

Plant growth regulators are opening the door to unheard of yields

Reading Time: 5 minutes Plant science and breeding technologies have been at the forefront of the last century’s new yield plateaus, particularly in corn. First was the development of hybrid seed production along with research that led to an understanding of fertilizer and then weed control. Most recently, biotech innovations have provided enhanced pest and weed management opportunities. Amidst […] Read more

Linda Hall is looking for the right combination of variety choice and agronomic practices to make oats more attractive to growers in central Alberta.

The Catch-22 of oat production

Tests in central Alberta yield some useful information on N rates and the effectiveness of plant growth regulators

Reading Time: 4 minutes Linda Hall has a soft spot for the humble oat, mainly because she doesn’t think it’s really all that humble. “Milling oats are a high-value crop,” Hall says. “We’re seeing companies like Richardson buying up oat milling capacity, so the markets are there if we can grow the right kind of oat.” It all depends […] Read more
