Abstract:
Sulphur, as a secondary nutrient is vital for tea crop.
Although, the importance of sulphur in tea crop
nutrition was recognized long ago, it received little
attention compared to other nutrients. This could be
due to the fact that sulphur estimations in soil and
plant are tedious. Quite often, sulphur needs were
met through low analysis fertilizers like ammonium
sulphate, single superphosphate and some organic
sources. However, with increase in productivity of
crop over time, removal of sulphur and increased use
of high analysis fertilizers viz. urea, di-ammonium
phosphate, and triple superphosphate etc. further
hastened the depletion of sulphur from the soil. This
review aims at consolidating the information
available and help in identifying information gaps in
our knowledge and suggest future lines of research.
