Abstract:

A pot culture experiment was conducted in the Radioisotope Laboratory, Department of Soil Science and Agricultural Chemistry, Tamil Nadu Agricultural University, Coimbatore to study the effect of sulphur (S) on changes in bio chemical composition, protein and oil content of groundnut. Also, the utilization of applied S and per cent sulphur derived from fertilizer (%Sdff) was studied using radiotracer technique employing sulphur -35 (35 S) radioisotope. The pot culture experiment was carried out in completely randomized block design in an S deficient soil (7.19 ppm) with twelve replications and S was applied @ 0, 20, 40, 60 and 80 kg ha-1. Per cent sulphur derived from fertilizer increased with increasing doses of sulphur and lower utilization of applied S was noticed at higher levels of applied sulphur [15.89 % (S20) - 5.45 % (S80)]. Sulphur application resulted in increased synthesis of methionine, cysteine and resulted in increased protein content. Sulphur application at 60 kg ha- 1 remained on par with S @ 40 kg ha-1 in influencing the oil and protein content.
