Grain Sorghum 2015 OVT Results in Virginia

2015 Sorghum OVT Yield in Virginia

I hear that several seed companies offer a 9% discount for pre-ordered seed, so I though this information may help.

The link above takes you to the grain sorghum variety trials results in 2015 including yield, seed moisture, and test weight. 22 hybrids were tested this year in full season and double cropping production systems at several locations in Virginia: Suffolk, Warsaw, Windsor, and Locust Grove. In order to effectively desiccate before harvest, the full season hybrid trial was grouped in two desiccation groups based on hybrid maturity.  The first table in the attachment combines locations and desiccation groups; the others show data for each location, cropping system and desiccation with mean separation by the Least Significant Difference test.

In general, 2015 was a good year for grain sorghum in Virginia. In spite of seed sprouting in the head due to storm Joaquin and the short “visit” of the sugarcane aphid towards the end of summer at some southeastern locations, yields were good. Only at Windsor yields were near to but not quite 100 bu/acre. For all other locations, yields at and in access of 100 bu/acres were obtained for many hybrids. DEKALB’s DKS53-53, DKS51-01, DKS54-00; Sorghum Partners’ NK6638, Pioneer’s 83P17; Sorghum Harvest’s SH59G4; and Alta’s AG3101 and AG1203 were top yielding hybrids in both cropping systems.

Last but not least, I would like to acknowledge the collaborators for help with the OVT trials this year, Dr. Wade Thomason with the Crop and Soil Environmental Science Department and Bob Pitman with the Eastern Virginia AREC.

 

Peanut state meeting

Virginia state peanut meeting is scheduled for February 10, 2016, at 9:00 am at the Airfield 4-H Conference Center in Wakefield, VA (15189 Airfield Rd, Wakefield, VA 23888
(757) 899-4901; http://www.airfieldconference.com/). See you there!

Eastern Shore AREC Specialist Day

Join us next week, November 17th, at the Eastern Shore AREC (33446 Research Drive, Painter, VA, 23420) for Weed Science Specialist Day.  Topics will include new herbicide technology and control of herbicide-resistant Italian ryegrass in wheat.  The event will begin at 10:00am and conclude at 12:00pm.  Lunch will be served promptly following the meeting.  Please RSVP to Ursula Deitch (ursula@vt.edu) or Theresa Long (tmjlong@vt.edu) by Friday if you are interested.  See the below flyer for more details.

Specialist Day will be held at the Eastern Shore AREC on Tuesday Nov. 17th.

Herbicide-resistant Italian Ryegrass

With harvest in full swing, it is hard not to forget about weed control in wheat.  Primarily of concern is herbicide-resistant Italian ryegrass.  In the past, ACCase- (Hoelon) and ALS-inhibiting (PowerFlex and Osprey) herbicides provided control of this weed.  However, Italian ryegrass biotypes resistant to these products have developed, but that is not to say these herbicides will no longer work in your area.  For example, Osprey is still effective throughout most of Eastern North Carolina, but once you move into the Piedmont, ryegrass control by Osprey is hit or miss.  In areas with known ALS-resistant Italian ryegrass, Zidua is suggested delayed-preemergence.  Delayed-preemergence means 80% of germinated wheat seeds have a shoot at least ½-inch long.  If applied prior to this stage, injury may occur.  Zidua is a seedling-shoot inhibitor and will not control emerged weeds, therefore, it is important for fields to be clean prior to application.  Axiom applied spike (applied preemergence, Axiom can cause severe injury) also controls Italian ryegrass if a timely activating rainfall is received following application.  Another option on no-till or minimum-till fields (where stubble from previous crop has not been incorporated) is Valor SX applied preplant.  Valor must be applied at least 7 days prior to wheat planting and should be applied in combination with either paraquat or glyphosate to control emerged weeds.  Tillage should not be performed after Valor SX is applied.  Italian ryegrass control by Finesse is variable and growers should expect only suppression.  If Finesse is applied, plant only STS-soybean following wheat harvest.  Postemergence options for Italian ryegrass include Axial XL and Osprey.   Although most Italian ryegrass is Hoelon-resistant, Axial XL (also an ACCase-inhibiting herbicide) still seems to work in most areas.  Osprey may also control Italian ryegrass in areas yet to develop resistance and will also control small bluegrass.

Virginia Peanut Latest News

In Virginia peanut digging started this year two weeks earlier than in most years, on Sep 15 in most counties. This is because of the combination of genetics, early maturing cultivars, and weather. One may say this summer was dry. Indeed, it was and some fields were more affected by drought than others. But it was a certain type of drought: cool and wet alternating with warm and dry long periods of time. For example, May was warm and dry, and suitable for early flowering; June and half of July were cooler and moist; perfect for peg and pod growth. And that was it: one huge, uniform crop set early on in the season and not two crops like we usually see in dry years. Altogether, by mid Sep the 2600 accumulated heat units were sufficient for Bailey and Sugg, the mostly grown cultivars in Virginia this year, to mature.

 Over 85% of the peanuts in Virginia have been dug and in most part picked by now. Yields of those picked before Joaquin and dug after the storm are in 4,000 lb/ac yield and grades are good. Peanuts dug right prior to Joaquin are in good shape, but a lot of pod shedding occurred and this will reduce yield. The peanuts dug a week ahead of storm are in poor shape and some segregation 2 peanuts with a high content of damaged kernels was sold. No segregation 3 was yet reported. A lot of sprouting was also observed.

Murphy Brown is buying sprouted sorghum

Some good news on the sprouted sorghum: Murphy Brown is taking all sorghum (sprouted or not).  They will be feeding sprouted grain immediately. They will be paying for sprouted grain based on test weight.  Same discounts apply as with non-sprouted grain (source: Barney Bernstein, Entira). I was also informed that on Eastern Shore the Coastal Commodities local elevator is applying a $.50/bu discount for sprouted sorghum, but they are taking it, too. http://www.coastalcommodities.com/
