A field experiment was conducted during 2010 at Puliyur village, Cuddalore district, Tamil Nadu with sesamum (Sesamum indicum L. cv. VRI-1), as a test crop. The treatments consisted of application of gypsum, lignite fly ash (LFA), pressmud (PM) alone or in combinations. The treatments were. T1 – control; T2 – 40 kg S ha-1 as gypsum; T3 – 40 kg S ha-1 as LFA; T4 – 40 kg S ha-1 as PM; T5 – 20 kg S ha-1 as gypsum + 20 kg S ha-1 as LFA; T6 – 20 kg S ha-1 as LFA + 20 kg S ha-1 as PM; T7 – 20 kg S ha-1 as gypsum + 20 kg S ha-1 as PM. The recommended dose of S to sesame is 40 kg ha-1. The experiment was laid out in randomized block design (RBD) and replicated three times. The growth and yield attributes were recorded on 25, 50 and 75 days after sowing. The seed and stover yields were recorded at harvest stage. The results of the experiment clearly revealed that the application of 20 kg S ha-1 as gypsum + 20 kg S ha-1 as LFA (T5) significantly influenced the yield, quality and nutrient uptake in sesamum. The treatment with 20 kg S ha-1 LFA + 20 kg S ha-1 as PM (T7) proved to be secondary and the treatments next in order were 20 kg S ha-1 as gypsum + 20 kg S ha-1 as PM (T6) 40 kg S ha-1 gypsum (T2) 40 kg S ha-1 as LFA (T3) and 40 kg S ha-1 PM (T4) respectively.
