plants lack water during the R1-R2 stage
and they received enough afterwards. On
the other hand, yields will be substantially
affected when the plants missed water
during the R4-R5 stage. It is also possible
to observe symptoms of a magnesium or po-
tassium deficiency.
When the soil is not humid enough, the
movement of potassium towards the roots
is slowed down. A potassium deficiency
can diminish your yields. Consult your agro-
nome to verify your fields for a potassium
deficiency.
Cereals:
During the stem elongation stage
(between the stage where the ear is 1cm
and flowering) the number of ears and
grains is set in place. This phase is more
sensitive to a lack of water and can translate
into the plant not having sufficient nitrogen.
are some important observations
year has it’s own particularities!
Potassium deficiency
Manganese deficiency in fall wheat
Manganese deficiency
The consequences of this include a de-
crease in tillers (fewer ears) and in the case
of a si-gnificant drought, less fertile ears.
Dry seasons can cause a manganese de-
ficiency in wheat. To learn more, consult an
agronome at le Club agroenvironnemental
de l’Estrie.
