Great Bend Tribune
Published February 7, 2021
The Drought Monitor is mostly unchanged again this week.听 Our area is still abnormally dry.听 And we haven鈥檛 become drier.听 Last week鈥檚 precipitation didn鈥檛 benefit all areas around Barton with the precipitation heavier east and south of Great Bend.听 Anything since Tuesday won鈥檛 show up until this Thursday. 听However, the areas to our south and southeast are pretty much out of drought.听 The six to ten-day outlook (February 10 to 14) indicates well-below normal temperatures and a neutral precipitation outlook. The eight to fourteen day outlook (February 12 to 18) indicates a strong chance of continued below normal temperatures and below normal precipitation.听 Looks like the groundhog鈥檚 prediction was correct.
Two brief topics for today:听 What should be happening with the current winter wheat crop?听 And why don鈥檛 we grow spring wheat in Kansas?
The current winter wheat crop: The forecast for well-below normal temps this week will slow down green up and development of the 2021 wheat crop but it鈥檚 certainly should be a time of increased activity.
- It鈥檚 already the second week of February with longer days and soon increasing temperatures.听 Wheat will start to take off and should be jointing, first hollow stem, in about a month or so.听 It鈥檚 time to consider topdressing wheat with nitrogen and some producers already have started.听 It鈥檚 not as simple as it sounds.听 Producers need to evaluate the stand in each field and take an educated guess as to yield potential while realizing many things can go wrong between now and mid-June.听 It鈥檚 not merely evaluating the stand and tillering but also soil moisture status while looking at the thirty and ninety day weather outlooks.听 Fortunately prices for wheat are much better than a year ago.听 Unfortunately fertilizer prices are going up.听 Once a yield estimate is determined the next item is:
- It鈥檚 best to apply nitrogen before the wheat takes off if possible to minimize the possibility of leaf burn, especially if using solution (liquid) nitrogen sources such as 28% UAN.听 It鈥檚 less critical if using broadcasting dry urea.听 And it would be nice if it could be applied before a snow or rain as that would help move the nitrogen into the soil and the root zone.
- Also important is weed control which can be applied along with solution nitrogen fertilizer.听 This not only eliminates an extra pass over the field but increases herbicide activity on emerged weeds.听 For certain herbicides, it鈥檚 important to wait until tillering is complete before applying.听 And it鈥檚 even more important for producers with thinner stands as thinner stands increase the opportunity for weed pressure.听 Finally, care should be taken with residual herbicides so they don鈥檛 interfere with a double-crop or other rotational consideration.
- Lastly, soon it will be time to monitor for insects such as cutworm and a little later aphids.听 Having to spray will be a function of insect pressure, growing conditions and overall plant health.听 So far the weather hasn鈥檛 been conducive for cutworm but that can change rapidly.
