TL;DR: It is suggested that other topics also need addressing, including better assessment of the wider benefits of intercropping in terms of multiple ecosystem services, collaboration with agricultural engineering, and more effective interdisciplinary research.

TL;DR: Physical defense traits, plant vigor and herbivore-induced plant volatiles show considerable utility in pest control, along with mixed species crops, and emerging approaches for accelerating the identification of plant defensive traits and facilitating their deployment are highlighted to improve the future sustainability of crop protection.

TL;DR: Examining root traits likely to improve the acquisition of essential mineral elements observes that, although the efficient acquisition of a particular element requires a specific set of root traits, suites of traits can be identified that benefit the Acquisition of a group of mineral elements.

TL;DR: A retrospective analysis of the effects of nearly 75 years of breeding of spring barley was undertaken to identify physiological mechanisms governing NUE and targets for future improvement, indicating possible opportunities for improving the efficiency of pre-anthesis N uptake.

TL;DR: It is argued that the mechanisms operate in a manner which is directly analogous to associational defence against herbivores, a process well-recognised in the facilitation literature.
