Counting Wheat Tillers

Posted by romeethredge on January 17, 2014

We have counted tillers in several wheat fields today. There are 2 reasons for doing this. We need at least 2 tillers per plant to be able to put a good wild radish, chickweed and henbit control on some fields, MCPA plus Harmony extra is often used in our area.

Here the rows are 7.5 inches wide so we are measuring 19 inches down the row to get a square foot and counting total tillers in that area. Once we know the average number of tillers per square foot we can make some decisions about wheat sidedressing.  We want close to 100 tillers per square foot and if we are below that we generally go ahead with half our fertilizer sidedressing the last week in January and the rest the second week of February.

If we have 100 or so tillers per square foot and good growth and don’t see much yellowing of the older foliage, we can wait until the 2nd week of February to put all our sidedress fertilizer.

Most all the fields we checked today need the split fertilizer applications.
