Untangling genotype by management interactions in multi-environment on-farm agronomic experimentation
Abstract
Identifying optimum combinations of genotype (G) and agronomic management (M) i.e. crop design, to match the environment (E) i.e. site and expected seasonal conditions, is a useful concept to maximise crop yields and farmers’ profits. However, operationalising the concept requires practitioners to understand the likelihood of different E outcomes and GxM combinations that would maximise yields while managing risks. Here we propose and demonstrate an analysis framework to inform crop designs (GxM) at the time of sowing of a dryland crop, that combines data sets from multi-environment field experimentation and crop simulation modelling, and that accounts for the risk preference of the decision maker.
Professor Daniel Rodriguez
Prof Rodriguez completed his MSc and PhD at Dept of Theoretical Production Ecology, Wageningen University The Netherlands. He has a background in crop eco-physiology and systems modelling with an extensive record of publications in high-impact scientific journals. In 2001 he moved to Australia where he worked at the Victorian and Qld DPI, before moving to UQ-QAAFI in 2010. His research explores the functioning of agricultural systems, usually working in multidisciplinary teams with the participation of farmers, private consultants, agribusinesses, and policy.

About Science Seminars
Queensland Alliance for Agriculture and Food Innovation hosts science seminars across the disciplines of animal, horticulture, crop, food and nutritional sciences.
With a range of speakers from Australia and abroad, the series explores how high-impact science will significantly improve the competitiveness and sustainability of the tropical and sub-tropical food, fibre and agribusiness sectors.
