  • Introduction-
  • Sulphur is one of the seventeen nutrient
    elements which are essential for the growth
    development of plants. Its essentiality was
    established in 1911 by Horstmann.
  • On an average, crops absorb as much as they
    absorb phosphorus. Plants absorb S mostly through
    roots in the sulphate form (SO42-) to a much
    lesser extent from the atmosphere in gaseous form
    (SO2).

  • Importance of Oilseed crops
  • Importance of oilseed as sources of both fats
    proteins is well known the annual requirement of
    oilseed in India.
  • In India, a variety of oilseed such as
    groundnut, sesamum, mustard, soybean, safflower
    etc. are grown. However, about 85 of countrys
    edible oils are derived from groundnut, mustard
    crops.
  • The nutrient which plays multiple role in the
    nutrition of oilseed cops is sulphur. It is an
    essential constituent of Sulphur containing amino
    acids, protein as well as several fatty acids
    (oils).

10
  • Role of Sulphur in oilseed crops
  • Sulphur is essential in formation of plant
    protein because it is a part of certain amino
    acids which act as building blocks of proteins.
  • It is an important constituent of several other
    biologically active compounds such as vitamin B1
    (thiamine) vitamin B7 (biotin).
  • Lipoic acid, acetyl co-enzyme A, ferrodoxin
    glutathione other biologically active sulphur
    containing componds which play in important role
    in plant metabolism include sulphate-3.
  • Phosphoadenosive-5 phosphosulphate is
    involves in the synthesis of glucosides in
    mustard oil.
  • Sulphur promotes nodule formation, although it
    is not a constituent of chlcrophyll.
  • Sulphur is involved in carbohydrate metabolism of
    the plants by activating a no. of enzymes which
    participate in dark reaction of photosynthesis.

11
  • Role of sulphur in general crops
  • Sulphur plays an important role in improving the
    quality marketability of the produce as
    reported by Kanwar (1976), sulphur can improve
    crop quality in the following ways
  • Increasing the oil content of seeds.
  • Synthesis of sulphur containing amino acids
    protein .
  • Improving nutritional quality of forage.
  • Improving starch content of tubers.
  • Improving baking quality of wheat.
  • Raising sugar recovery in sugarcane.
  • Enhancing marketability of copra.

12
Deficiency symptoms of sulphur in oilseed crops
Crop Symptoms
Mustard Leaves cupped inwards and reddening on underside.
Sunflower Pale leaves and inflorescence, shorter internodes, markedly smaller plants.
Soybean Pale yellow colour of new leaves at beginning but due to severe deficiency whole plant becomes yellow, smaller leaves and shorter internodes.
Groundnut Young plants are smaller than normal, pale in colour and more erect from the petiole than normal plant. This gives the trifoliate leaves a V shaped appearance. Older leaves may remain green. In new leaves, area around the main vein may be pale.

Correction of sulphur deficiency In view of the
increasing incidence of sulphur deficiency in
soils plants, it is important to suggest
corrective measures for ameliorations of sulphur
deficiency. The major source of sulphur are
gypsum, pyrities, elemental sulphur (85.5),
and the sulphur containing nitrogenous (amonium
sulphate), phosphatic (SSP), potassic (potassium
sulphate) fertilizer and micronutrients
fertilizers like zink sulphate, copper sulphate,
ferrous sulphate etc. are used for correction of
sulphur deficiency.
15
  • Source of Sulphur
  • The earth crust contains nearly 0.06
    sulphur which is costly present in the form of
    sulphides, sulphates organic combinations of
    C N.
  • Over 60 sulphur containing fertilizers are
    known to agriculture, but main fertilizers
    soil amendments as source of sulphur in India.
  • The fertilizers soil amendments, mentions
    above indirectly add every year a substantial
    amount of sulphur to the India soils.

Besides addition of sulphur through fertilizers
containing sulphur. It is also advisable to apply
20-50 kg S/ha as elemental Sulphur (sulphur
powder) mainly to oilseed crops. This dose should
be applied 3-4 weeks before planting in moist
aerated soil.

Effect of applied sulphur on nutrient use
efficiency in different oilseed crops Because of
the significant increase in crops yield by
sulphur fertilization, the uptake of other
nutrients significantly increased reflecting
marked increase in nutrient use efficiency.

  • Conclusion
  • The major reason for low yields of oilseeds is
    their cultivation on marginal land with
    constraints on fertilizer irrigation.
  • Full potential of newly evolved high
    yielding varieties of oilseed crops, fertilizer
    sulphur must form a part of their integrated
    management programme.
  • The balanced rates of different fertilizer
    nutrients including sulphur should be worked out
    for different oilseed crops.
  • There are also the need to develop extension
    literature on sulphur fertilization and wall
    charts, slides sets and video cassettes on the
    subject.
  • Agriculture universities should suggested to
    the state soil testing laboratories about
    precise sulphur recommendations based on soil
    testing.
