Planting Late Wheat

The best time to plant winter wheat is 10 days after the fly-free-safe date for Hessian fly (shown here for Ohio:  http://ohioline.osu.edu/iwy/flydates.html).  Ohio counties are now well past the 10-day window for optimum wheat planting.  Wheat fall growth is reduced when planting is delayed resulting in reduced winter hardiness.  However, if freezing weather does not occur until late November or early December, wheat planted up to three weeks after the fly-free-safe date can achieve the same yield as wheat planted within 10 days of the fly-free-safe date.  If wheat is planted three to four weeks after the fly-free-safe date (which is now for northern Ohio), it is recommended to increase seeding rates to 1.6-2.0 million seeds per acre or 24-30 seeds per foot of row.

Weather Outlook for October 28 to November 3, 2012

The outlook for the week of October 23, 2012 calls for much above normal temperatures and limited rainfall.  Some rainfall will move mainly across northern Ohio on Tuesday, October 23 with a mostly dry trend for mid to late week.  Rainfall will generally be 0.10 to 0.25 inches in northern Ohio with isolated totals higher in the far northern 1-2 tiers of counties.  A cold front will bring some rain Friday into Saturday with rainfall totals in the 0.25 to 0.75 inch totals with a few totals over 1 inch especially in the western half of the state.

The outlook for the week of October 28 to November 3, 2012 calls for below normal temperatures.  Precipitation will range from below normal in the west to above normal in the northeast.  There is high uncertainty in the forecast this weekend into next week as to how a storm from Canada may or may not interact with a tropical system off the East Coast.  There is a high chance of a freeze later this weekend into next week with a moderate chance of a wind event and a low chance of a little snow.  The main risk for the rain and wind will be in the northeast part of the state as well as a little snow.  Again, confidence is low but we wanted to let you at least know there is a chance especially in the northeast part of the state for some unwanted severe weather.
