Aims

To assess the performance of winter and spring wheat germplasm managed under three different levels of management (22nd April sown).

Key messages

• Winter feed wheats RGT Accroc and Anapurna were significantly higher yielding than all other cultivars tested giving yields over 10t/ha and a 2t/ha advantage over Scepter.
• The ASW wheat DS Bennett was significantly higher yielding than all other white wheat milling varieties.
• Of the AH classified wheats Nighthawk and Beckom were the highest yielding (mean of the three managements).
• There was a significant reduction in yield as a result of defoliation (simulated grazing) at GS30 when the results from all cultivars were averaged.
• Although there was some evidence that the different varieties responded to management differentially the interaction was not statistically significant (p=0.06).
• Dry matter (DM) contents at harvest ranged from 17 – 20t/ha with significantly higher DM accumulation in the longer season winter wheats such as RGT Accroc, Anapurna and DS Bennett compared to Scepter.
• Greater dry matter accumulation with the winter wheat up to GS30 was the result of a longer vegetative period that correlated to higher tiller number per unit area and tillers/plant.
• At harvest however although there were more heads/m2 with winter wheats they were not always significantly higher than spring wheats indicating greater tiller mortality in winter wheats compared to springs.
• In general, disease (principally Septoria and stripe rust) has been controlled by the two spray programme set out in standard management approach, however those varieties that tended to give higher yields at higher input (not significant) were in general the more susceptible.
• The increased nutrition (18kg N/ha and 25kg S/ha) and PGR applied with the high input approach did not generate any notable yield gains.
• In those cultivars that lodged (Gregory, Catapult, Beckom and Trojan) there was no indication that the PGR application reduced lodging, although there were significant positive effects from grazing on standing power.
• Protein levels averaged just 11% and indicated that yields were optimised at the level of N application.
• Harvest indices for winter wheats were in general closer to 37-40% compared to higher yielding spring wheats that were closer to 45%.
