Abstract

                                Field experiments were conducted in Coimbatore District with discrete soil sulphur status i.e., soils with sufficient and deficient levels of sulphur to know the relative response of graded levels varied doses of sulphur on two different sesamum varieties. The experiments were laid out in split plot design with two factors viz.,two sesamum varieties (TMV 7 - Black var. and SVPR 1 - White var.) and Six sulphur levels (0, 20, 30, 40, 50 and 60 kg S ha-1 ). The results revealed that application of 30 and 50 kg S ha-1 at sulphur sufficient and sulphur deficient soils respectively has increased the yield parameters such as test weight, seed weight per plant, seed yield, stalk yield, oil yield and biological yield. Between the two varieties, TMV 7 has performed better when compared with SVPR 1.Under both the soil sulphur status, further increase in the level of sulphur recorded a non-significant increase in the yield attributes.
