Disorders

3.  NitrogenDeficiency
SymptomsSlow growth stems
thin spindly and hard and fewer
lateral shoots. Leaves fade to
yellowish green, even yellow, any
may trun brown and die in severe
cases; lower leaves first affected;
leaves are smaller and thinner
than normal. Some purpling
may develop under low
temperature conditions.
 Correction MeasureFoliar
spray of Urea 1% at fortnightly
intervals.

4.  PhosphorusDeficiency
SymptomsMaturity is
delayed stems are thin and
woody with shorter than
normal growth. Leaves
smaller and darker green;
undersides have a reddish-
purple coloration, on leaf
veins, fibrous root
development.
 Correction MeasureFoliar
application of DAP 2% at
fortnightly intervals.

5.  PotassiumDeficiency
SymptomsStems slender
become woody. Basal leaves
first affected, grayish yellow
or brown colour especially at
margins, which develop
scorched appearance; specks
develop along veins of leaf
with chlorotic areas in
leaf. Root are poorly
developed and discoloured.
 Correction MeasureFoliar
spray of 1 to 2 % KCl at
fortnightly intervals

6.  MagnesiumDeficiency
SymptomsLoss of healthy
green colour between the
veins of the older leaves,
later spreading to younger
leaves. This inter-veinal
chlorosis may turn brown,
leaves become brittle and
older leaves may drop.
 Correction
MeasureFoliar spray of
MgSO4 1% at fortnightly
intervals.

7. Symptoms
 Older leaves,
intervenal chlorosis
and reddish tinting
Table Beet Plant Magnesium deficiency

8. Symptoms
 Younger leaves
chlorotic and high
red tints.
Table Beet Plant Iron deficiency

9. Symptoms
 Leaves triangular
shape, margins
curled forward;
older leaves
severely speckled;
root dwarfed
Table Beet Plant Manganese deficiency

10. Symptoms
 Leaves triangular
shape, margins
curled forward and
severe intervenal
speckling.
Table Beet Leaves Manganese deficiency

11. Symptoms
 General field view.
Foreground:
susceptible "globe"
variety severly
speckled;
Background:
resistant long
variety
Table Beet Manganese deficiency

12. Symptoms
 Collapse of foliage,
beginning with
young leaves;
rotting of outer
tissues of the roots.
("Canker")
Table Beet Plants Boron deficiency

13.  BoronDeficiency
SymptomsPlants dwarf and
stunted. Leave are small. The
young leaves fail to develop, turn
brown or black and dies. Leaves
assume varigated with yellow and
purplish red blotches stalks with
longitudinal splits. Leaves
twisted rough and gresh
appearance. Roots become hard
and way.
 Correction MeasureBorax
10kg/ha or Foliar spray of
solution (20%B)

14. Symptoms
 Transverse section.
"Canker" lesions,
mainly in outer
tissues.
Table Beet Roots Boron deficiency

15.  IronDeficiency
SymptomsInterveinal
chlorosis which may
develop to a more
uniform yellow, almost
white, in the younger
leafs.
 Correction
MeasureFoliar spray of
FeSO4 0.5% at
fortnightly intervals.

16. Symptoms
 Hooking distortion
and marginal
scorch of young
leaves; growing
point killed
Seakale Beet Plant Calcium deficiency

17.  ManganeseDeficiency
SymptomsDeformation of
leaves with red
pigments. Leaves become
brittle. Interveinal
chlorosis in newly
emerging leaves become
redder and show narrow
chlorotic striping.
 Correction
MeasureFoliar spray of
5% MnSO4 twice at
fortnight interval.
