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

ABSTRACT.
Excessive vine growth not only negatively impacts fruit composition but also fosters bunch rot incidence. The goal of our study was to improve Vitis vinifera (Tannat) grape and wine composition and decrease bunch rot incidence by achieving adequate vine vegetative growth in a humid climate. Our approach was to use under-trellis cover crops (UTCC) to limit vine water availability and reduce excessive vine growth. We tested UTCC consisting of full cover of the vineyard soil with red fescue (Festuca rubra) versus conventional alleyway red fescue with 1.0 m wide weed-free strips under the trellis (H). As excessive competition with grapevines remains the main reason for UTCC rejection, this strategy was tested in combination with two irrigation schedules?irrigation to avoid water restriction at bloom (Ir) vs. no early irrigation?and two nitrogen inputs (0 vs. 100 kg N ha−1) over three growing seasons in southern Uruguay. Treatments were arranged in a split-split-plot randomized block design with cover crop schemes as main plots, water availability as subplots and nitrogen inputs as sub-subplots. Shoot growth rate, mid-day stem water potential (Ψstem), berry size and berry composition were monitored over the season, as well as final yield, cluster and pruning weights. UTCC significantly reduced vine vegetative growth, while no significant differences were detected between H and UTCC when irrigation took place early in the season. Even nitrogen input showed positive effects on grapevine vegetative growth in some cases, water availability at bloom was the key driver of vegetative growth. UTCC treatments increased grape soluble solids (TSS) in the last two out of three seasons and consistently increased anthocyanin concentration in grapes. Independent of vegetative growth, strong differences in bunch rot incidence were detected between H and UTCC treatments. Seasonal variations in water status and/or free amino nitrogen content of grapes may have a relevant impact on disease susceptibility at harvest.
