ABSTRACT.- Context: Demand for dairy products is expected to continue driving intensification in dairy systems. Little is known about the productive and economic performance and risk of intensification strategies either within grazing systems or confinement dairy systems in Argentina.cu Objective: This study investigated four strategies to double milk production for the average grazing dairy system of Argentina (BASE), using either grazing or confinement systems. Physical and economic performance and risk associated with each alternative was explored using a modelling approach. Investment of capital required to establish each alternative was estimated. Methods: Four scenarios that double milk production per farm from a BASE scenario were designed and modelled using a whole-farm model named e-Dairy: two grazing dairy systems with different milk yield per cow per year: GR6750 (6750 L/cow per year) and GR7500 (7500 L/cow per year) and two confinement systems, an open dry yard (DRYLOT) and a compost bedded pack (COMPOST). Stochastic budgeting was used to model the combined influence of variation in milk, price and crops yield. Outputs of the stochastic analysis are shown in the form of cumulative distribution functions (CDF). Results and conclusions: All the intensification alternatives increased milk production per ha from 7800 L, in BASE system, to 18,209 and 26,758 L in grazing and confinement systems, respectively. Intensified scenarios required an investment of capital between two and three times higher than the BASE scenario. All scenarios had positive economic results. The BASE scenario showed both the lowest farm operating profit and the lowest return on assets ($99/ha per year and 4.1%, respectively). Intensified grazing systems had the highest return on assets (above 12%), while the COMPOST system showed the highest farm operating profit ($1121/ha per year) and the lowest return on assets (7.5%) of the intensification alternatives explored. According to stochastic simulations, the COMPOST and DRYLOT scenarios would expose farmers to a greater maximum loss than BASE and grazing scenarios when negative farm operating profit occurred. However, cumulative distribution functions of profit showed that they would have higher profit than BASE and grazing scenarios along most of the CDF curve. Significance: Farmers who decide to intensify their systems will have higher profit compared with BASE scenario, but should be prepared to afford higher investment and also to cope with increased variability of profit under price or climate risk. If the switch from a BASE scenario was to be implemented at a national scale, it would impact on surplus milk that might cause significant changes beyond farm gate. Further research is required to investigate the environmental impact of intensification alternatives.

ABSTRACT.
Aims Sugarcane is a multipurpose crop mostly used in Uruguay for bioethanol production. It requires high amounts of N fertilization for optimal growth, which causes environmental degradation and high production costs. Previously, a bacterial collection associated with surface-sterilized stems of sugarcane was characterized for in vitro plant growth-promoting (PGP) traits. The aims of this study were (1) to determine if selected isolates from the collection are sugarcane growth promoters and (2) to determine if they are true endophytes
of sugarcane. Methods Plant growth promotion assays were used to study the effects of selected isolates on sugarcane plantlets. Light microscopy, transmission electron, and scanning electron microscopy (TEM, SEM) were employed to describe the structure of the interaction between the plant growth-promoting bacteria and the plants. qPCR was used to quantify the bacteria residing in the inner plant tissues. Results Enterobacter sp. UYSO10 and Shinella sp. UYSO24 were confirmed to have a PGP effect on the commercial sugarcane cv. LCP 85384. Both strains were defined as true endophytes of sugarcane plants with this being the first case for a strain in the genus Shinella in grasses. Conclusions These data will contribute to the final development of a sugarcane PGP inoculant based on endophytic plant growth-promoting bacteria.
