Essentiality of sulphur was established in 1911 by Peteson.
Sulphur is now rightly called the fourth major plant nutrient
next to N, P and K.
S content in oilseeds is 1.1 per cent, 0.3 per cent in pulses
and 0.2 per cent in cereals.
Sulphur is a key nutrient for oil seed production because in
the plants, sulphur takes parts in the formation of oils,
proteins and glucosides and the sulphahydral linkage which
provide the source of pungency in mustard oil.
It is also a structural constituent of chlorophyll, vitamins and
metabolism of carbohydrates.

5. India is among the largest vegetable oil economies in the
world next only to USA and China.
In the agricultural economy of India, oil seeds are important
next only to food grains in terms area, production and
value .
India accounts for
-13% world’s oilseed area
-7% world’s oilseed output
-10% world’s oil consumption
But the introduction of high yielding varities and other
cultural practices made the soils S deficient and it adversely
affected the oil seed production and quality.

12. Oil seeds are energy rich crops and
in terms of energy equation.
1Kg of oil = 1.66 g of proteins
=2.37g of CHO

1.It is required for the synthesis of the S containing amino acids cystein,
cystine and methionine and for protein synthesis.
2. It activates certain proteolytic enzymes such as papainase and synthesis of
papain.
3. It is a constituent of certain vitamins viz., Thiamine and biotin, coenzymes
and glutathione, Acetyl coenz A (precursor for fatty acid synthesis),ferredoxin.
4. It is present in the crops like onion, mustard, cabbage and cauliflower as
polysulfides.
5. It increases oil content of crops like flax, soybean, groundnut etc.
6. Disulfide linkages (-S-S - ) have been associated with the structure of
proteins.
7. Sulfhydryl (-SH) groups in plants are related to increased cold resistance.
8. It is required for N fixation in legumes and is a part of nitrogenase enzyme
system.

51. Application of sulphur in oilseed crops through different sources
results in higher yield and high oil content over a control.
The average improvement in yield of different oilseed crops vary
from 10 to 40 per cent due to application of 30-60 kg sulphur/ha.
Among different sources of sulphur, gypsum is the cheapest
source and most abundantly available.
The overall result indicated that sulphur play a vital role in
improving yield and quality of oilseeds.
51
52. To create the awareness among the farmers for S utilization.
Relationship of sulphur and other nutrient need to be
establish.
The balanced rates of different fertilizer nutrients including
sulphur should be worked out for different oilseed crops
