Ruminant livestock are a vital global source of highquality protein and bioavailable minerals and vitamins. They support healthy dietary choices by providing milk and meat produced from less productive land and food industry byproducts. However, despite the contribution of ruminants to food systems and the circular bioeconomy, ruminant production systems are increasingly questioned due to their environmental impact, particularly their significant contribution to greenhouse gas (GHG) emissions and associated global warming.

Este artículo pone el foco en la implementación práctica del manejo por ambientes de campo natural, aplicado a la gestión del Canutillo. Sobre la base de experiencias en ensayos y predios comerciales, INIA junto a los productores evitan ?luchar? contra la planta y se concentran en favorecer las mejores características de la especie, buscando transformar al Canutillo de ?villano a héroe del campo natural?

ABSTRACT - BACKGROUND: The redbanded stink bug Piezodorus guildinii (Heteroptera: Pentatomidae) is one of the most important species affecting soybean crops in southern South America. Capillary gas chromatography coupled to mass spectrometry was used to characterize the epicuticular hydrocarbon profiles of field-collected insects, and to identify differences in their composition between fifth-instar nymphs and adults, males and females, and between bugs collected in insecticide-treated and insecticide-free soybean crops.

The Rio de la Plata region comprises central Argentina, Uruguay, and southern Brazil. Modern agriculture developed around 1900 with recent decades being characterized by the advance of cropping areas over native grasslands. Highly specialized agriculture has decoupled crop and livestock production but has succeeded in intensifying yields. However, significant losses of ecosystem services have been reported. Thus, questions have been raised on the sustainability of this pathway.

Selection of improved genotypes is important for pasture-based feeding systems in subtropical regions. Our goal was to identify hybrids of Paspalum with enhanced forage yield and cold tolerance across 2 sites [Bagé and Eldorado do Sul (ES)], in Rio Grande do Sul, Brazil. We evaluated 19 P. plicatulum × P. guenoarum hybrids, P. plicatulum genotype 4PT, P. guenoarum cultivars Azulão and Baio and, as Control, Megathyrsus maximus cv. Aruana. At both sites, the experimental design was a completely randomized block with 4 replications.

ABSTRACT. Context. - Despite a wealth of analytical knowledge on factors and processes that operate to slow down or impede sustainability transitions in various sectors of society, design-oriented researchers face a lack of guidance on the ?how to? question for developing knowledge to support sustainability changes. From 2007, we crafted co-innovation as an approach for governance and management of change-oriented projects, combining three domains; a complex adaptive systems perspective, a social learning setting, and dynamic monitoring and evaluation. Objective.

El objetivo de estas jornadas del ciclo de Destacadas INIA 2020 fue poner el foco en la importancia de planificar con suficiente anticipación la implantación de nuestros recursos forrajeros para el próximo otoño.
