Abstract: Soil acidity is one of the major factors which have an apparent role in the production of crops predominantly in oilseeds. The present field investigation was carried out during summer (Kharif) season of 2014 with the aim to evaluate the response of sulfur (S) and lime (CaCO3) application on the productivity and nutrient uptake of sesame in acidic soil. The field experiment was laid out according to a factorial randomized block design with three replications and 16 combinations. Elemental sulfur (S0-S) was applied as basal dose @ 0, 15, 30 and 45 kg ha-1 along with three lime doses @ 0, 100, 250 and 350 kg ha-1. Sulfur and lime application at all the levels considerably enhanced the values of all parameters. Sulfur application of 30 kg ha-1 performed well as compared to other levels in respect to seed yield (282.75 kg ha-1), stalk yield (359.84 kg ha-1), biological yield (632.44 kg ha-1) and harvest index (44.15%) of sesame along with uptake and content of N, P, K and S in seed and stalk; although S application @ 30 kg ha-1 was observed statistically comparable at P=0.05 with 45 kg S ha-1. Likewise, lime application @ 250 kg ha-1 found statistically at par with the lime rate of 350 kg ha-1 in respect to all these parameters.
