El Programa Nacional de Investigación en Producción Frutícola de INIA viene considerando desde el año 2007 el potencial de desarrollo del cultivo frutícola comercial del nogal americano o pecán. Dado el potencial identificado para este rubro en el país, y la falta de conocimiento sobre el manejo del cultivo y su comportamiento en nuestras condiciones, el primer paso para comenzar las investigaciones en pecán fue instalar un ensayo comparativo de cultivares.

ABSTRACT.- Apple trees set many more fruit than desired, requiring a crop load adjustment to achieve acceptable fruit size in the season and an adequate return bloom, thus avoiding biennial bearing. Thus, the aim of this study was to evaluate the effect of different plant growth regulators as 6-benzyladenine (6-BA) and naphthaleneacetic acid (NAA) sprays and lime sulfur (LS) in apple thinning. Two trials were carried out in Uruguay on 2020/2021 growing season in 'Gala Baigent' and 'Rosy Glow' apples, respectively. Productive and quality parameters were evaluated.

ABSTRACT.- Pear production in Uruguay covers 628 ha being 'Williams' the most planted cultivar. Orchards in Uruguay are managed without the use of pollinizers (parthenocarpy). Pear production in recent years has not been stable, there are many factors that could be influencing, including climatic conditions, low fruit set, among others. The aim of this study was to evaluate the use of plant growth regulators to increase fruit set in 'Williams' pears in orchards with and without pollinizers.

Extension of tropical and subtropical crops to colder regions, favored by global climatic changes, represents a challenge for cold stress adaptation. An upsurge of cold injury is being registered in different crops and regions, constraining growth and yield. Abiotic stresses are considered a growing threat for sustainable agriculture by compromising plant growth, finally leading to the reduction of crop productivity. The aim of achieving cold adaptation with a minimum crop yield and quality detriments will help to accomplish "zero hunger" global objectives.

ABSTRACT.- This work aims to contextualize and analyze the potential contribution of pecan to SDG2 under the dual perspective of carbon storage and human nutrition. Particularly, the study focuses on the pecan agroecosystems in the Americas, representing the most important pecan-producing countries (the United States, Mexico, Brazil, Argentina, Uruguay, and Peru). We observed that pecan is a reliable sink for storing atmospheric C and also for quality nuts with high nutritional density. The Americas, hold a population of ca.

ABSTRACT.- Conventional viticulture involves a high use of inputs that negatively impact ecosystem services and biodiversity. Traditionally, vineyards are rainfed systems and vegetation is removed or sprayed with herbicides to avoid excessive competition for water and nutrients. Introducing cover crops can positively promote several ecosystem services and particularly soil and crop health and biodiversity.
