Aims

To assess the performance of winter and spring wheat germplasm managed under three different levels of management 

Key messages

 The trial produced the highest yields since 2016 when HYC yields exceeded 16t/ha at the research centre.
 Four varieties yielded in excess of 14.5t/ha with Cesario under high input (five fungicide units, 260 kg N/ha and split PGR) topping the yields with 15.2t/ha. RGT Accroc and Big Red under the same input were slightly lower yielding than 15t/ha.
 The superior disease resistance (primarily STB and leaf rust) exhibited by Big Red and RGT Cesario resulted in superior yields under standard input compared to the more disease susceptible RGT Accroc and Anapurna.
 There was significant interaction between cultivar and management (p=0.039) meaning that cultivars responded differently to the three management levels applied.
 Although it was not always statistically significant mechanical defoliation “grazing” reduced the yield of the winter wheats relative to the standard management input. However with the earlier developing spring wheats there was no difference in performance.
 It should be noted that in part the reduction in yield with the winter wheats might have been partially offset by adding more nitrogen post grazing.
 Both Scepter and Trojan gave significant yield increases in response to higher input, principally associated with additional fungicide.

 Grain protein levels indicated that levels of N fertiliser applied did not need to be increased from 200 to 260kg N/ha as only Tabasco had a protein level below 10.3%.
 Influence of fungicide input was most evident in Trojan, particularly with regard to test weight.
