Crop Management PhD International Research Scholarship @ UCD Dublin Ireland

Crop Management PhD International Research Scholarship @ UCD Dublin Ireland: University College Dublin has its origins in the mid-nineteenth century under the leadership of the renowned educationalist John Henry Cardinal Newman. Since its foundation in 1854, the University has flourished and made a unique and substantial contribution to the creation of modern Ireland, based on successful engagement with Irish society on every level and across every sphere of activity. Crop Management PhD International Research Scholarship @ UCD Dublin Ireland

PhD Position

This is a fully funded 4-year PhD is offered for a project entitled “Development of imaging models of the Soil/Root interactions for cereal crops – primarily wheat – for use to improve cereal establishment”.

Crop Management PhD International Research Scholarship @ UCD Dublin Ireland

This PhD is part of a larger research project looking at crop establishment, soil nutrients and crop management. For this particular PhD, times of sowing and cultivation strategy are key related components in cereal production. Seedbed preparation is crucial for crop establishment, growth and ultimately, yield; however, different crops require differing soil physical properties for successful establishment.

There is a need to investigate reduced or low disturbance techniques and their capacity to reduce establishment costs, increase sowing capacity and facilitate alternative sowing dates. The interaction between sowing date and cultivation/sowing system and its effect on soil and root structure needs to be determined. However, direct visualisation of root:soil interactions has been impossible due to roots growing in opaque soil.

This task will assess the impact of cultivation systems, sowing times and soil types on the soil structure and cereal root systems and ultimately crop yield. It will utilise X-ray CT scanning of soil cores taken from the field plots. X-ray CT is a 3D non-destructive technique that can be repeatedly undertaken on the same soil core; allowing soil structure, soil pores and root system architecture to be simultaneously visualised and quantified at scales relevant to root:soil interactions. In this task X-ray CT will be used to directly visualise soil-seed contact and obtain data regarding the effect that different cultivation methods have on soil structure to gain information regarding the optimum seedbed for cereal establishment.

Objectives:

1. To determine the impact of conventional, and low disturbance crop establishment systems on cereal establishment.

2. To study the interaction between sowing date and establishment system as assessed by crop establishment, development and yield.

3. To investigate the effect of seedbed conditions (sowing depth, tilth level, tilth depth, soil structure etc) on cereal root development.

To apply submit an electronic copy of Curriculum Vitae, a letter of interest and names and email addresses of two academic referees to Dr Kevin McDonnell electronically. For informal questions and queries, please email Dr. Kevin McDonnell or Dr Saoirse Tracy.

Closing Date for applications: Saturday, 24th June, 5:00pm (Irish time)
