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. The study was performed during the 2021/2022 growing seasons using two different 'Williams' pears orchards, the first one five-year-old orchard grafted on 'Adams' with 'Packham's Triumph' as pollinizer, and the second one, a three-year-old orchard grafted on 'OH×F40' without pollinizer. Treatments consisted of an untreated control, and different aminoethoxyvinylglycine (AVG) and 6-benzyladenine + gibberellins 4+7 (6-BA + GA4+7) rates sprayed at full bloom and 7 days after full bloom. Productive and quality parameters were assessed. Fruit set was affected differently in the two orchards (with and without pollinizer), where in the orchard with pollinizers, AVG and 6-BA + GA4+7 increased fruit set, number of fruit and yield of 'Williams' pears. A negative effect of 6-BA + GA4+7 sprays compared to untreated trees and AVG-treated trees was fruit misshapenness, where the combination of these active ingredients showed a higher level of misshapen fruit. In the orchard without pollinizers, the best results were observed with 6-BA + GA4+7 sprays, where AVG did not show significant differences between treated trees and control trees. Collectively, our results showed both plant growth regulators may represent an efficient tool to increase fruit set and yields of 'Williams' pears, however, AVG showed increase in fruit set only in the orchard with pollinizer and 6-BA + GA4+7 in both orchards. 6-BA + GA4+7 treated trees had an increase in the misshapen fruit level when compared to untreated control trees and AVG-treated trees and could reduce the fruit commercial value. © 2023 International Society for Horticultural Science.

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
