Sulphur application to crop fields has drastically reduced due to the use of high-analysis fertilizers such as diammonium phosphate (DAP) instead of superphosphate and urea instead of ammonium sulphate over many years, resulting in widespread sulphur deficiency in Indian soils. Looking to the wide spread S deficiency in soils of Gujarat, a field study was conducted at the Agronomy Farm, B. A. College of Agriculture, AAU, Anand to evaluate the effect of sulphur-coated urea (SCU) as source of sulphur, besides improvement in Nitrogen use efficiency in mustard crop. The effect of Neem coated urea (NCU) coated with 6% Elemental Sulphur (ES) significantly increased mustard grain yield to the tune of 15.23% over control. However, 6% coating either Prilled or Neem coated urea enhanced Nitrogen recovery efficiency.
