197. Clustering of indicator species according to soil properties in the regeneration phase of pedunculate oak (Quercus robur L.) forests

Anamarija Jazbec (University of Zagreb Faculty of Forestry and Wood Technology)

21/05/2026, 10:45

oral presentation

Regeneration of forest ecosystems is crucial for preserving their structure, function and long-term stability. This research analyses the correlation and similarity of the occurrence of 11 species characteristic only for the regeneration phase with respect to some soil properties. Aim of research is to perform grouping of species according to soil properties, and to determine differeces in...

207. Quality over Quantity? - The optimised allocation of quality samples in Bavarian post-registration trials in perennial ryegrass

Anne-katrin Gorn (Bavarian Research Center for agriculture)

21/05/2026, 11:03

oral presentation

In Germany, cultivars are tested for regional recommendations in federal state cultivar trials, taking the form of multi-environment trials (METs). Their primary objective is to identify cultivars that are best suited for regional production in agro-ecological zones. For perennial ryegrass, current selection decisions are predominantly based on yield. Incorporating additional quality...

150. Challenges and Perspectives on Using Environmental Covariates in Multi Environment Trials A Case Study in Sugar Beet

Maksym Hrachov (University of Hohenheim)

21/05/2026, 11:21

oral presentation

Environmental covariates (ECs) have become increasingly abundant and accessible over the past two decades, driven by advancements in remote sensing, data acquisition technologies, and the declining costs of environmental monitoring. Incorporating ECs into multi-environment trials (METs) has several applications, including improving the understanding of genotype-by-environment interactions,...

92. Optimizing the allocation of trials to sub-regions in crop variety testing: different conditions in different years

Maryna Prus (University of Hohenheim)

21/05/2026, 11:39

oral presentation

New crop varieties are extensively tested in multi-environment trials in order to obtain a solid basis for recommendations to farmers. When the target population of environments is large, a division into sub-regions is often advantageous. If the same set of genotypes is tested in each of the sub-regions, a linear mixed model (LMM) may be fitted with random genotype-within-sub-region effects....

131. Assessment of a Low-Cost System for 3D Image Acquisition in Beef Cattle

Milene Figueira (UFRPE)

21/05/2026, 11:57

oral presentation

The use of precision agriculture contrasts with the challenge posed by the high cost of commercial technologies, particularly for small-scale producers. For this reason, it is necessary to develop low-cost, accessible solutions that can be applied directly in the productive environment. Within this context, this work presents the development of a low-cost system for acquiring 3D images of beef...
