Production & postharvest

The Department of Primary Industries and Regional Development contributes to the productivity, profitability and sustainability of plant-based agriculture. From broad scale dryland cropping systems to intensive irrigated production, we work with industry and business to address challenges in plant production through research and development, knowledge transfer and government policy settings.
