ABSTRACT.- Grasslands are often mis-defined, mainly due to the legacy of colonial narratives in several regions, which have described them as deforested, unproductive or wastelands. They have been largely ignored in global conservation and protection policies, leading to increased exploitation. Although there is much accumulated evidence on the ecosystem services that grasslands provide, in Uruguay, this ecosystem is still neglected in parts of society and for most sustainability policies.

ABSTRACT.- Ramularia leaf spot (RLS), caused by the fungus Ramularia collo-cygni (Rcc), has become a threat to barley production in Argentina and the world, causing grain yield and quality losses. Characteristics of the pathogen such as a long latency period, high evolutionary potential, numerous transposonic regions and the ability to infect alternative hosts facilitate Rcc adaption to environmental changes and/or control measures such as fungicides. RLS is considered a sporadic disease in Argentina and its occurrence is highly dependent on weather conditions.

ABSTRACT.- Unknown parent groups (UPG) model missing parentships according to breed, year, and pathway of selection. Genetic evaluations need a sensible definition of rules to form UPG to ensure their accurate estimation. With more complex evaluations, systematic rules are needed to form UPG. We propose several methods to ascertain informativity and join consecutive UPG within breed and pathway.

ABSTRACT.- Exploitation of compensatory growth (CG) is a widely practised management strategy in beef production, especially under pastoral conditions due to its potential to reduce feed costs. The aim of this experiment was to evaluate the effect of nutritional restriction during backgrounding in Angus steers slaughtered at either similar age and/or similar BW on feed efficiency, body composition, carcass characteristics and meat quality attributes under either a forage or feedlot-based finishing diet.

ABSTRACT.- Recognizing evaluation results as a crucial source of information to support RD&I management, this article introduces 'AgroRadarEval', an interactive tool aimed at fulfilling theoretical, conceptual, and practical gaps concerning the systematization of the use of evaluation results in agricultural RD&I.

ABSTRACT.- There is a need for rigorous and scientifically-based testing standards for existing and new enteric methane mitigation technologies, including antimethanogenic feed additives (AMFA). The current review provides guidelines for conducting and analyzing data from experiments with ruminants intended to test the antimethanogenic and production effects of feed additives.

ABSTRACT.- Questions: Degradation of facilitative interactions of native species can play an important role in the establishment and expansion of invasive plants in communities. We evaluated the relationship between the level of invasion of Cynodon dactylon and the arbuscular mycorrhizal colonization of the native Paspalum notatum in Uruguayan grasslands, which were either extensively managed (natural vegetation [NG]) or oversown with exotic legumes and fertilized with phosphorus (NG + LP).

ABSTRACT.- Spatial crop yield prediction provides valuable insights for supporting sustainable and precise crop management decisions. This study assessed the capabilities of advanced Deep Learning (DL) architectures in predicting within-field soybean yields using spectral bands from Sentinel-2 (RS-Inputs), weather (W-Inputs), and topographic attributes (TA-Inputs). © 2024 The Author(s).

ABSTRACT.- Introduction: Improving the feed efficiency (FE) in ruminants offers significant potential for optimizing the use of natural feed resource while simultaneously

ABSTRACT.- Wheat (Triticum aestivum L.) is a key global crop essential for food security. Enhancing wheat productivity is crucial to meet growing food demands. Quantitative trait loci (QTL) such as QFFE.perg-5A and QFEm.perg-3A have been previously linked to fruiting efficiency at the spike level, but their effects on plot-level yield components remain unexplored. 4290/© 2024 Elsevier B.V.
