This collection features six peer-reviewed reviews on optimising rootstock health.The first chapter considers recent advances in irrigation techniques used in sustainable vegetable cultivation and reviews the performance and efficiency of these systems. The second chapter details the need to optimise precision in orchard irrigation management, focussing on matching water supply to plant demand as a means of achieving this. The third chapter assesses irrigation management systems for tomato production and how these can be optimised alongside nutrient management to ensure the production of safe and nutritious tomatoes. The fourth chapter summarises the common types of irrigation systems found in soilless culture production, as well as the emergence of new systems, including plant-based sensing and monitoring systems. The fifth chapter highlights the need for more sustainable water use in ornamental production systems and the methods which can be used to achieve this, such as reducing runoff volume. The final chapter considers recent advances in irrigation management in greenhouse cultivation, focussing on water balance, crop evapotranspiration techniques and irrigation scheduling.
