Se realizó una encuesta entre los productores semilleristas del Uruguay con el objetivo de caracterizar la tecnología aplicada para la producción de semillas forrajeras y diagnosticar los principales factores limitantes que inciden actualmente, tanto para la obtención de mayores rendimientos como para la expansión del área. La misma fue dirigida a productores que cosechan semilleros, es decir cultivos sembrados con el propósito específico de cosechar semillas. Intervinieron 228 productores, que en conjunto representa un área de cosecha de aproximadamente 16.500 hectáreas. La producción de semillas se realiza principalmente en predios agrícola-ganaderos, integrada como un rubro más dentro de establecimientos que producen carne, leche, lana, granos, etc.. Sólo en el 3% de los establecimientos encuestados la producción de semilla es el rubro principal. La mayor parte de los productores que respondieron el formulario multiplican más de una especie y se localizan en el sur-oeste del país. Casi la mitad (41%) de los productores también cosechan áreas que no fueron específicamente destinadas a semilleros. Los resultados de la encuesta indican claramente que existe un importante potencial para la expansión de la actividad semillerista. |

Environmental impact and sustainability of agricultural systems and management practices leading to climate change mitigation
are one of the most relevant issues to agricultural production nowadays. Mitigation is the process of reducing emissions or
enhancing sinks of greenhouse gases (GHG), to limit global warming potential and restrict future climate change. The most
relevant GHG are Carbon dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O). The steady increase of its concentrations
in the atmosphere over several decades has led to enhance global warming. CH4 and N2O are the most relevant GHG emitted
mainly in the agricultural sector. It is well known that water management has great impact on GHG emissions from rice paddy
fields. One of the most important tools for rice crop production and mitigation of CH4 emission is the controlled irrigation.
However, it could result in a N2O emission increase and reduced rice yields. For these reasons, it is remarkably important to
assess the tradeoff relationship between both GHG and the effect on rice productivity. A 3 year field experiment with two different
irrigation systems was set at southeast of Uruguay. Conventional water management (continuous flooding after 30 days of
emergence, CF30) and an alternative irrigation system (controlled deficit irrigation allowing wetting and drying, AWDI) were
compared. The objective was to study the effect of water management on GHG emission, water productivity and rice yields in
order to identify strategies for further progress in sustainable intensification of Uruguayan rice. Results showed that mean
cumulative CH4 emission values for AWDI were 55% lower than CF30 systems; on the other hand, there were no significant
differences in N2O emission among systems. Significant yield differences were not observed in two of the rice seasons, while
AWDI recorded a significant yield reduction in one of them. Total irrigation water applied and irrigation water productivity did not
showed differences in two of the rice seasons, while CF30 reported a higher amount of water applied and lower water
productivity in one of the seasons. It can be concluded that AWDI could be an option to enhance water productivity and GHG
emission mitigation. However, grain yield can be compromised in AWDI systems. The adoption of these technology is based
on the indispensable assess of an overall tradeoff between the risk of possible yield losses, total water used and GHG
emissions. MenosEnvironmental impact and sustainability of agricultural systems and management practices leading to climate change mitigation
