Abstract: A field experiment entitled “Yield and nutrient content and uptake by clusterbean (Cyamopsis tetragonoloba L.) as influenced by different levels of sulphur and zinc application under light textured soil” conducted during summer season of 2013 at Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The experiment encompassed three levels of sulphur viz., 0, 20 and 40 kg S ha^-1 and four levels of zinc viz. 0, 2.5, 5.0 and 7.5 kg Zn ha^-1. The experiment was laid out in randomized block design (Factorial) with three replications. The soil of the experimental field was loamy sand in texture, alkaline in reaction and soluble salt content under safe limit. It was low in organic carbon, available N, S and Zn medium in available P₂O₅ and K₂O. The results revealed that application of 40 kg S ha^-1 with 5.0 kg Zn ha^-1 gave significantly, higher seed (750.92 kg ha^-1) and stover yield (1163.9 kg ha^-1). The individual application of 40 kg S ha^-1 and 5.0 kg Zn ha^-1 recorded significantly higher nitrogen, phosphorus, sulphur and zinc content and uptake by seed and stover of clusterbean. Application of 40 kg S ha 1 recorded significantly highest sulphur status in soil after harvest while maximum DTPA-extractable zinc status was registered under the application of 7.5 kg Zn ha^-1.
