To look at nitrogen and sulphur management in wheat.

Key messages
  • Small differences in yield with extra N under conditions at this site.
  • Very dry spring needs to be taken into consideration when interpreting results.
  • High rates of N early did not have significant impact on number of tillers.
  • Grain quality higher for all N treatments.
  • Further work required with ENTEC, eNtrench and Biopolymer urea coated product.
