Aims

To assess the performance of winter and spring wheat varieties managed under three different levels of management sown in mid-April (20th April).

Key messages

 Winter type cultivars outyielded the spring cultivars by 3.3 to 4.9t/ha across all levels of input management. Winter red feed wheat Anapurna significantly outyielded all other cultivars except RGT Cesario.
 The response to higher input (PGR, 4 units of fungicide, additional N) was greatest with RGT Accroc (4.38t/ha) which was greater than Anapurna (2.17t/ha) > Calabro (2.03t/ha) > Big Red (1.94t/ha) > RGT Cesario (1.17t/ha).
 The rank order of these responses to higher input primarily aligns with susceptibility to Septoria tritici blotch (STB) and leaf rust susceptibility so it would appear that fungicide input was an important aspect of the higher input (4 units vs 2 units).
 There was no significant interaction of cultivar and management observed in this trial, meaning that all varieties responded roughly the same to the different management levers, with all varieties responding to the high input strategy.
 Cesario was the only cultivar to achieve >10 t/ha in all three management strategies (grazed, standard and high input) and was the most resistant to disease.
 In addition, Cesario was the only cultivar to accumulate statistically similar levels of total dry matter at harvest in the grazed compared to the high input strategy, which likely led to it being the only cultivar to achieve 10t/ha grain yield in the grazed strategy.
 Anapurna maintained % grain protein (>13%) across all management strategies. This was also achieved in the spring milling cultivar Trojan, whilst the other spring milling cultivar, Scepter, achieved significantly higher protein (≥14.4%) in the Standard and High Input strategies than all other cultivars and strategies.
 11t/ha grain yields were observed in varieties that achieved over 20t/ha dry matters at harvest.
