We have a decent looking wheat crop right now. With the forecast looking a little warmer over the next 10 days, now is a good time to do some tiller counts.
We should be seeing at least 50 tillers per square foot. If we are under that, we may want to split our remaining N into two applications. If over 50, we can apply the remaining N in one shot later in February to make sure it’s all out by the time jointing starts.
On a 7.5″ spacing, count the number of tillers in 19″ of row (7.5 x 19 = 144 square inches or 1 square foot). Count a few different areas of the field to come up with an average tiller count. The field pictured above was just over 50, so it will have its remaining N put out in one shot in a few weeks.
Take a look at the “Fertility” and “Tiller Counts” sections of the Wheat Cheat Sheet for more info.
