El Huanglongbing (HLB) o Greening es el principal problema sanitario de la citricultura uruguaya. La enfermedad fue detectada en plantas de traspatio en la ciudad de Bella Unión en enero de 2023 y hasta la fecha no ha sido encontrada en plantaciones comerciales pero su presencia en el país es un riesgo para la producción citrícola. El objetivo de este trabajo fue relevar la presencia de D. citri y la entomofauna benéfica presente en quintas comerciales en el sur del país.

En la primavera 2012 se implementó el programa de manejo regional de lepidópteros plaga en frutales de hoja caduca a cargo de DIGEGRA, DGSA, INIA y FAgro. El programa tiene como objetivos la reducción sistemática de los lepidópteros plaga a niveles poblacionales predeterminados mediante la aplicación de una estrategia de manejo basada en la confusión sexual y el monitoreo de carpocapsa y grafolita en toda el área frutícola del sur del país, sumándose el monitoreo de lagartitas.

The Uruguayan rice-livestock system is one of the most productive worldwide, adding meagre amounts of N as fertiliser and reaching a very tight nitrogen (N) balance (N-BAL), low N surplus (N-SUR) and a high system N use efficiency (NUE), being a good example of a circular economy system.

The objective was to evaluate the relationship between P balance (P fertilization minus P removal in grain) on the evolution of soil P availability (P Bray I analysis).

The specific objective is to study the effect of previous P fertilization on P fixation according to soil type.

This study investigates the co-inoculation of soybeans with rhizobia and PMB Bacillus strains with and without addition of P fertilizer on plant P uptake and crop yield.

Pasture response to N fertilization and the nitrogen use efficiency (NUE) is highly conditioned by the phosphorus (P) availability and soil water. The objective of the study was to evaluate the effect of NP fertilization on the NUE of annual ryegrass, in two growth periods.

Current sustainability challenges of production systems require comprehensive answers with a multidimensional approach. The objective of this study is to select indicators that allow quantifying the productive-economic, social, and environmental evolution of dairy systems transitioning towards agroecology through a co-innovation approach.

Nutrients deficiencies - mainly phosphorus (P) and nitrogen (N) - often depress forage productivity (FP) in pasture-based systems in the Pampas region (Argentina). Fertilizations are often used to attenuate these deficiencies, but it is necessary to increase the use efficiency of the applied nutrients.

Uruguayan dairy farms underwent an important intensification process during the last decades. Although pasture-based grazing systems are still dominant, one important component of such intensification is the increase of extra-farm feed inputs, along with an increased stocking rate and an increased supplementation rate per cow.
