A revised version of the
publication "Replanting or Late Planting Crops" could be helpful
to barley producers.
"In addition to reducing yield, late planting can accentuate the
challenge of growing barley to malt quality," says Joel Ransom,
North Dakota State
University Extension Service cereal grains agronomist. "Late
planting increases the likelihood of high temperatures during
grain filling that can reduce plumpness and increase grain
protein."
Ransom suggests seeding on the heavy side, which may improve
yield slightly in the late-planted barley, though this probably
will not increase the level of plumpness. Growers should back
off on their nitrogen rate when planting late to help moderate
protein content.
"Some viral diseases, such as barley yellow dwarf and wheat
streak mosaic, can be more problematic in late-planted fields
when the insects that vector these diseases are more plentiful
and active," Ransom says. "Carefully monitor the barley crop for
aphids that can vector the barley yellow dwarf virus. Apply
insecticide when aphid populations are building to reduce the
incidence of barley yellow dwarf."
Ransom also serves on the Institute of Barley and Malt Sciences
(IBMS) Extension Team as a team leader. The IBMS has its
headquarters at NDSU and seeks to provide reliable,
high-quality, targeted research and education for U.S. barley
producers and domestic and international malting and brewing
industries at a single site. NDSU IBMS Extension teams advise
the IBMS staff on barley education and research efforts.

or from a county NDSU Extension Service office. |
