Sulphur (S) plays a pivotal role in various plant growth and
development processes being a constituent of sulphur-containing
amino acids, cysteine and methionine, and other metabolites viz.,
glutathione and phytochelatins, co-factor of enzymes which
contribute to stress repair and amelioration of heavy metal
toxicity. Besides, a number of S-containing components are
biologically active and, thus, a source for use as medicinal value.
The basic global issue before the agricultural scientist and world
community is to evolve cultivars and develop methodologies for
efficient use of inputs to enhance agricultural productivity. This
is particularly true of the developing countries which are going to
see maximum rise in population with changing food demands and
declining availability of land. Amongst the inputs, nutrients play
a crucial role. The major requirement is for N, P and K followed by
several micro-nutrients. In this context reports of world-wide S
deficiency in the agricultural systems are relevant. The reasons
are many. Broadly speaking reduction inS emission, use of S-free N,
P and K fertilizers and higher biomass production contributed the
maximum. Despite the need for sulphur as an essential plant
nutrient and the substantial returns expected from its use, very
little attention has been given to fill the gap between supply and
demand of S.
