ABSTRACT.- The use of alternative waste products as organic soil amendments has become increasingly important for researchers and the industrial sector, as they promote environmental protection and sustainable development. The objective of this study was to assess phytotoxicity of different pulp industry sludge rates applied to two soils as soil amendment, based on their effects on seed germination and radicle elongation of tall fescue (Festuca arundinacea) and common wheat (Triticum

ABSTRACT.- Background: Single-step genomic BLUP (ssGBLUP) has gained increasing interest from forest tree breeders. ssGBLUP combines phenotypic and pedigree data with marker data to enhance the prediction accuracy of estimated breeding values. However, potential errors in determining progeny relationships among open-pollinated species may result in lower accuracy of estimated breeding values. Unknown parent groups (UPG) and metafounders (MF) were developed to address missing pedigrees in a population.

ABSTRACT.- Changes in light conditions may affect invasiveness as they can constrain different stages of plant development during the invasion process. This is particularly true in grazed grasslands, as livestock selectively removes above-ground biomass, promoting light heterogeneity. We assessed how light intensity and quality affect the germination and growth of Eragrostis plana, one of the most invasive alien grasses of the Río de la Plata grasslands (southern Brazil, Uruguay, and eastern Argentina).

Greenhouse gasses potential offset by forest species and CO2 balance in integrated forestry-livestock systems in Uruguay. [Potencial de mitigación de gases de efecto invernadero por plantaciones forestales y balance de CO2 en sistemas integrados ganadería-forestación en Uruguay.]. [Potencial de mitigação de gases de efeito estufa a partir de plantações florestais e balanço de CO2 em sistemas integrados pecuária-floresta no Uruguai.].

ABSTRACT.- Uruguay's livestock methane is a mayor source of greenhouse gas (GHG) emissions, despite the country's low overall emissions. A case study was conducted on Forestal Caja Bancaria (FCB), a commercial farm in Uruguay's central region, with an integrated production system covering 5,802 hectares. The study aimed to estimate GHG emissions from livestock, crops and forestry, CO2 captured by eucalypt and pine plantations, and soil organic carbon for all land uses. -------------------------

Resistance to leaf rust in cultivars and wheat lines of Paraguay. [Resistencia a roya de la hoja en cultivares y líneas de trigo de Paraguay]. [Resistência à ferrugem da folha em cultivares e linhas de trigo do Paraguai].

ABSTRACT.- Leaf rust (LR) of bread wheat (Triticum aestivumL.), caused by the fungus Puccinia triticina Eriks, is one of the most important diseases in Paraguay, the Southern Cone of America and worldwide. The economic importance of the disease is clear considering that two or more fungicide applications are necessary to control the disease in susceptible cultivars. The best strategy for the management of this disease is through genetic resistance.

A graduated methodology for mitigating GHG emissions and nutrient losses in integrated crop-livestock production systems. [Metodología gradual para mitigar las emisiones de GEI y las pérdidas de nutrientes en los sistemas integrados agrícola-ganadera.]. [Metodologia graduada para mitigar as emissões de GEE e as perdas de nutrientes em sistemas integrados de produção agropecuária.].

ABSTRACT.- The agricultural sector must mitigate losses in greenhouse gas (GHG) emissions, nutrients, and inputs within the context of climate change and ecosystem degradation. Integrated crop-livestock production systems can enhance carbon and nutrient circularity. A holistic methodology is proposed to guide producers in developing strategies that reduce environmental impacts while improving system resilience through circular and ecosystem based practices. Developed as part of the Integrity project (EraNet), this methodology presents a graduated approach organized into four stages.

Assessing the contribution of enteric methane emissions from Uruguayan livestock to global warming using an alternative metric.

ABSTRACT.- For years, livestock production has been accused of having a supposed impact on global warming. This message permeated broad sectors of public opinion. Recently, questions have arisen about the metrics used to determine the potential contribution of different greenhouse gases.

Identification of sheep robust to climate change and variability. [Identificación de ovinos robustos al cambio y la variabilidad climática.]. [Identificação de ovinos robustos às alterações e variabilidade climáticas.].

ABSTRACT.- Livestock production, in particular sheep farming, faces the challenge of increasing food production in the context of limited resources, with less access to arable land and sup-plements. In addition, explained by variability and climate change, access to high-quality and quantity pastures and water would be soon restricted. Furthermore, sheep will be more frequently and for longer periods exposed to higher temperatures, to changes in the rainfall pattern and to a scenario of pests and diseases different from the current one.
