Abstract: A pot experiment was conducted at Department of Agricultural Chemistry and Soil Science, College of Agriculture, Junagadh Agricultural University, Junagadh to study the “Varietal Response of Soybean [ Glycine max (L.)Merrill] to Sulphur in Medium Black Calcareous Soils during kharif 2012.The pot experiment comprising 20 treatment combinations, each replicated four time was laid out in factorial concept of CRD design with four different levels of Sulphur- Cosawet Sulphur (0, 5, 10 and 15 mg kg-1) and five soybean varieties viz., V1 (GS-1), V2 (GS-2), V3 (GJ-335), V4 (PK-472), V5 (GJS-3) were tested in the experiment, in respect of yield and yield attributes, content and uptake of nuutrient (NPK) by plant parts & their total uptake at different growth stages of soybean crop and status of soil available nuterint(NPK) at harvest. The experimental soil was vertic haplustepts medium black calcareous, clayey in nature which was slightly alkaline in reaction pH2.5 (7.8) and EC2.5 (0.58 dSm-1), low in available nitrogen (242 kg ha-1), medium in available phosphorus (39.20 kg ha-1), high in available potasium (320 kg ha-1) and medium in available Sulphur (21.50 kg ha-1).The concentration of nitrogen, phosphorus, potassium in leaves, shoot and root at 45 DAS and leaves, shoot, root and seed at harvest was remain unaffected. Almost, the maximum uptake of nitrogen, phosphorus and potassium by leaves and shoot and their total uptake at 45 DAS and at harvest were recorded with variety V5 (GJS-3). Similar trend was also observed in case of the uptake of NPK by seed at harvest. The availability of NPK in soil at harvest did not influenced significantly by varieties of soybean. The application of sulpur @ 15 mg kg-1also produced beneficial effect on uptake of nutrients (NPK) by plant parts and their total uptake at 45 DAS and at harvest. Application of Sulphur @ 15 mg kg-1gave significantly higher uptake of NPKS by leaves, shoot and root and their total uptake at 45 DAS and at harvest over that of lower Sulphur levels. Similarly, the maximum uptake of NPKS by seed recorded at Sulphur applied @ 15 mg kg-1. Similarly, the interaction effect of variety and Sulphur also found in respect of uptake of K and S by seed and registered significantly higher with variety V5 (GJS-3) at Sulphur level of 15 mg kg-1.
