WHY DO RESEEDED CROPS LOOK BETTER THIS YEAR?

This field was reseeded due to frost and looks good. You'll notice that some of the originals survived.

Various studies and crop insurance data show that canola seeded in early May tends to yield more than canola seeded in late May. Agronomy decisions are based on these trend results. But with the unpredictability of crop production, situations often come along that buck the trend. This year may be one of those years. Why?

SWATH TIMING FOR UNEVEN CANOLA FIELDS

Earliest canola in southern Alberta and here and there across the Prairies will be close to swath timing in the next week or two. Many of these early fields are not looking good, with patchy emergence, uneven emergence and short stature due to moisture stress.

HOW TO DO A CORRECT STRIP TRIAL

Take a full swath down the middle of each strip, then weigh the yield individually for each strip.

Strip trials are useful tools to test a product or practice to see if it improves the standard or “check” practice. Growers and agronomists may still have a few strip trial ideas for this year, say on swathing timing, for example. Here are common ways that strip trials are mismanaged, creating results of questionable value….
