About this Research Topic
Closing the yield gap in wheat production around the world through an understanding of the causes for this phenomenon is a major focus of the Wheat Initiative's Expert Working Group (EWG) for Agronomy. The main aim of the EWG is to consolidate the global expertise for agronomy with a focus on wheat production systems. The overarching approach would be to develop and adopt a “systems agronomy framework” relevant to any wheat production system. Such an approach first establishes the scale of current yield gaps identifying physiologically defensible benchmarks, and then takes a holistic approach to understand and overcome exploitable yield gaps. New opportunities to drive increased productivity would be sought by capturing future Genotype x Environment x Management (GxExM) synergies identified in different systems. The EWG would then be able to influence priorities for wheat agronomy research in member countries that would facilitate collaborations, minimize duplication and maximize the likely global impact on wheat production systems.
This Research Topic draws upon the work of an international, cross-disciplinary panel of experts, who contributed to the American Society of Agronomy Wheat Initiative Agronomists Community Symposia in 2017 and 2018 and who will focus, among other things, on:
- The role of crop management on regulating wheat yield;
- The importance of GxExM to increase yield of early sown wheat;
- Understanding the limitations to wheat production;
- Quantifying water, nutrient, and radiation use efficiency in wheat production systems;
- Linking the components in the GxExM complex.
