YIELD


The global average yield of oats in 2004 was 2.2 MT/ha according to FAO, though 7
or 8 MT/ha is possible in good growing conditions.
The UK reported the highest average yield for that year (6.0 MT/ha) and Israel
the lowest (363 kg/ha).
Harvesting should be done in good time (early) to minimise shattering.


UTILISATION
Oats are mainly used for animal food; both the grain - rolled, and with husks -
and the straw are eaten. The straw is highly absorbent, and so is good for
bedding.
The rest of the grain is dehusked and used for human food, as oatmeal, porridge,


husk does not develop, is also used, mainly for breakfast cereals.
Oatbran, and to a lesser extent oatmeal, are rich sources of inositol, part of the
vitamin B complex and important in nerve transmission, the metabolism and
movement of fats and for reducing blood cholesterol levels. Inositol is also

seeds and nuts, etc.
In some cold regions the young plants of winter sown types are grazed in
spring. If no top dressing is applied the grain yield may be reduced a little,
though with crops which are too thick (“winter proud”) the yield is often
increased by grazing.
The plants can make good hay and silage.
In industry, oat hulls are sometimes used as a source of furfural (or
furfuraldehyde) a chemical intermediate in the production of many industrial
products such as solvents and resins.

LIMITATIONS
