Wheat
is the primary small grain grown throughout Mississippi.
Wheat yields in the range of 30 to 50 bushels per
acre are common, and yields in the 60- to 80-bushel
range may be produced under good management and favorable
weather conditions. Oat yields from 70 to 80 bushels
per acre are common. Yields of more than 100 bushels
per acre have been made under good management and
favorable weather conditions.
Winter varieties of small grains require a certain
amount of cold weather (less than 40 °F) before
the plants will form reproductive structures (seed
heads). The period of time varies with variety, but
somewhere between 4 and 9 weeks of low temperatures
are required. This process is called vernalization.
Most of the wheat varieties planted in this state
require low temperatures to reproduce. In some years,
south Mississippi doesn't have enough cold weather
for winter wheat, causing little or no seed-head production.
Small grains are adapted to soil types throughout
the state. Avoid areas such as the wet, poorly drained,
heavy soils of the Delta and the wet, bottom areas
of the Hill section. Wheat will not tolerate poor
drainage conditions and still produce an economical
yield. Thin, badly eroded soils also will not produce
economical yields and should not be planted to grain.
