No. 115 Nitrogen use for spring wheat crops

The AIMI survey of New Zealand cereal growers, as at 1 July, 2024 is now available online.

This book outlines trial-specific yields and individual cultivar disease ratings for spring sown wheat and barley cultivars included in the 2024-2025 CPT trials.

High rainfall across most regions created challenges throughout the growing season, with sowing in some cases delayed until late November. Weather conditions also impacted crop management during the season.

The Autumn Cereal Cultivar Evaluation Book for 2024/25 is now available to read.

Planting a crop consisting of multiple cereal cultivars (cultivar mixtures) enhances genetic diversity, which can improve both seasonal and long-term agronomic performance and slow or reduce disease spread. To assess the viability of this approach for feed wheat production under current commercial conditions in New Zealand, FAR conducted a series of field trials in Chertsey, Mid Canterbury, between 2021 and 2024.

Part 2 of the 2024 Cereal Disease Management Strategy provides an overview of the research behind the development of this strategy. It’s the ‘extra for experts’ part, providing in-depth information that will help you to understand how and why to prioritise your fungicide spend.

T1 and T2 applications provide the majority of disease control, yield benefits, and economic returns. However, adding a T3 spray often creates the best balance in a fungicide programme. A T3 application is timed to protect the 22% of yield linked to the leaf sheath and ear, but need for it will depend on seasonal disease pressure. This update outlines examples of balanced and targeted fungicide programmes which will aid profitability and reduce pressure on both cultivars and chemistry.
