Resumo:  A pot experiment was conducted with clay loam alkaline (calcarous) soil frorn the University of Udaipur Agronomy farm in Rajasthan, India to determine the effécts of varying nitrogen and sulphur applications on. two wheat varietics at different stages of growth. One hundred kg/ha of nitrogen and 150 to 225 kg/ha of sulphur were found to be the optimum doses under all growth stages. Variety Vi (1-11) 2009 - Mticum aestivum) was found to be superiof to V2 (HD 4519 - Dificum durum) on all characters studied, íncluding chemical composition, with the exception of test weight. Total nitrogen and sulphur accumulation in the plant increased almost linearly until maturity. Thus, in a fertilization program it would be important to have an adequate supply of nitrogen and sulphur throughout the growing season. Application of nitrogen resulted in increased plant levels of phosphorus, calcium and sulphur. Sulphur application did not afféct plant levels of calcium and phosphorus; however, nitrogen content díd increase as sulphur application increased. In order to support satisfactory plant growth and developrnent, the soil used in this study must be able to sypply at least 1.5 to 4 mg of nitrogen per plant per week within the growth period of 55 to 135 days, and 1.3 to 3.5 mg of sulphur per plant per week during the same period.
