ABSTRACT.
Herbaspirillum seropedicae is a nitrogen-fixing bacterium capable of using toxic compounds as a source of carbon. Bacteria with this capacity can be used to make animals resistant to plant poisoning containing monofluoroacetate (MFA), such as Amorimia septentrionalis. The aim of this study was to evaluate if H. seropedicae is efficient in the degradation of MFA present in A. septentrionalis and if the inoculation of this bacterium in goats confers protection to A. septentrionalis intoxication. Two experiments were performed: in the first experiment 12 goats were divided into 2 groups. Goats in Group 1 were orally administered a solution containing the H. seropedicae bacterium for 10 days. From day 10 onwards, they received a daily dose of 5g/kg of A. septentrionalis with the bacteriauntil clinical signs of intoxication were observed. Group 2 goats received only the plant at the same dose, also until the observation of clinical signs of intoxication. The amount of MFA found in A. septentrionalis used in the experiment with goats was 1.6±0.058?g/mg. The total plant dose ingested by all goats in Group 1 was 80.83±12.81g/kg (129.33±20.50mg/kg MFA), which were significantly greater (p<0.05) than those of Group 2 goats (39.16±19.08g/kg plant and 62.66±30.53mg/kg MFA). Group 1 goats took an average of 16.16±2.56 days to develop clinical signs of intoxication, significantly longer (p=0.0012) than Group 2 goats (7.83±3.81 days). Two Group 2 goats died on the same day that they developed clinical signs of intoxication. At necropsy of these two animals, no significant changes were observed. In the second experiment, samples of A. septentrionalis were sprayed with a solution containing H. seropedicae. Before and eight days after spraying, the samples were pressed and dried for quantitation of MFA. The amount of MFA present in samples of A. septentrionalis 8 days after spraying with H. seropedicae was significantly lower (p=0.017) than that found prior to spraying. It can be concluded that administration of H. seropedicae in goats is capable of causing greater resistance to A. septentrionalis intoxication, and spraying the plant with this bacterium significantly reduces the amount of MFA in the plant.

RESUMO.
Herbaspirillum seropedicae é uma bactéria fixadora de nitrogênio, capaz de utilizar compostos tóxicos como fonte de carbono. Bactérias com essa capacidade podem ser utilizadas para tornar os animais resistentes à intoxicação por plantas que contém monofluoroacetato (MFA), como Amorimia septentrionalis. O objetivo do presente estudo é avaliar se H. seropedicae é eficiente na degradação do MFA presente em A. septentrionalis e se a inoculação dessa bactéria, em caprinos, confere proteção à intoxicação por A. septentrionalis. Foram realizados dois experimentos: no primeiro experimento foram utilizados 12 caprinos, divididos em dois grupos. Os caprinos do Grupo 1 receberam diariamente, oralmente, uma solução contendo a bactéria H. seropedicae durante 10 dias. A partir do décimo dia passaram a receber, diariamente, além da solução com a bactéria 5g/kg de A. septentrionalis até a observação de sinal clínico de intoxicação. Os caprinos do Grupo 2 receberam apenas a planta na mesma dose, também até que a observação de sinais clínicos de intoxicação. A quantidade de MFA encontrada em A. septentrionalis utilizada no experimento com caprinos foi de 1,6± 0,058µg/mg de planta em média. A dose total de planta ingerida por todos os caprinos do Grupo 1 foi de 80,83±12,81g/kg (129,33±20,50mg/kg de MFA), valores significativamente maiores (p<0,05) do que os dos caprinos do Grupo 2 (39,16±19,08g/kg de planta e 62,66± 30,53mg/Kg de MFA). Os caprinos do Grupo 1 demoraram em média 16,16 ±2,56 dias para desenvolver sinais clínicos da intoxicação, período significativamente maior (p=0,0012) que os caprinos do Grupo 2 (7,83±3,81dias). Dois caprinos do Grupo 2 morreram no mesmo dia que desenvolveram sinais clínicos da intoxicação. Na necropsia desses dois animais não foram observadas alterações significativas. No segundo experimento, amostras de A. septentrionalis foram pulverizadas com uma solução contendo a bactéria H. seropedicae. Antes e oito dias após a pulverização, as amostras foram prensadas e secas para posterior quantificação do MFA. A quantidade de MFA presente nas amostras de A. septentrionalis oito dias após a pulverização com H. seropedicae foi significativamente menor (p=0,017) do que a encontrada antes da pulverização. Pode-se concluir que a administração de H. seropedicae em caprinos é capaz de causar uma maior resistência à intoxicação por A. septentrionalis, e a pulverização da planta com esta bactéria reduz significativamente a quantidade de MFA na planta.

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
