PhD Project - Optimising Nutrient Management for Improved Productivity and Fruit Quality in Apples

Supervisors - Dr Nigel Swarts and Associate Prof Dugald Close

This study will investigate the relative contribution of each nitrogen (N) source, and the interaction between mineral nutrients (N, P, K) to apple tree growth and development, and fruit production and quality; using isotopic N tracing (15N) technique, mineral nutrient analysis, and fruit quality assessment. Previous study have quantified the key N sources such as fertiliser and plant residual, and internal N, the N loss from the soil-plant-atmosphere system, the storages and soil N content in a modern commercial orchard (Morris, 2015, Nigel Swarts et al., 2015). However, there are limited knowledge regarding the relative contribution of N sources and amount of plant N remobilised in the subsequent growing season and how that influences tree demands. In addition, substantial amount of bio-mass was removed from the system via leaf senescence and pruning, which can be a potential N sources for future plant growth. Current understanding of the impact of key mineral nutrients (N, P, K) is also limited. This project will be conducted in two parts, firstly, the short term fate of N derived from fertiliser and non-fertiliser sources in a commercial apple orchard will be investigated, and the impact of N fertiliser application timing and efficiency of alternative input methods such as foliar N application will be determined. Secondly, interaction between mineral nutrients (N, P, K) on fruit production and quality will also be investigated. Together, these new data will help identify tree N, P, and K requirements and improve our understanding of when, where and how N is translocated through the plant or lost from the root-zone soil.
