“…In Brazil, it is estimated that 60% of the production of forage grass seeds are of Urochloa brizantha (Euclides et al, 2010); however, in a study that aimed to evaluate the physical and physiological quality of those seeds in the 2006harvests, Ohlson et al (2009 found that 36-100% of the samples analyzed (depending on the harvest and cultivar) were not within the standards of physical and physiological quality established for commercial seed. The first count of germination and germination speed index were influenced by the application of consecutive cuts, year planted, and the cuts × years interaction (P<0.05) ( Table 4).…”

-The objective of this study was to evaluate the practice of consecutive cuts in the production and quality of Paspalum guenoarum seeds of the "Azulão" ecotype. The experimental design used was in completely randomized blocks with four replications. The treatment included three cuts in succession: zero cut, one cut, two cuts, and three cuts. The variables were: number of total tillers/plant; number of vegetative tillers/plant; number of reproductive tillers/plant; percentage of reproductive tillers; number of racemes/inflorescence; weight of thousand seeds; number of seeds/inflorescence; seed production; forage dry matter; water content of seeds; germination; first germination count; and germination speed index. The largest seed production was obtained with zero cut (850.3, first year and 719.4 kg/ha -1 , second year) and one cut (794.4, first year and 627.3 kg/ha -1 , second year) with no statistical difference between them. The largest germination percentage was seen with the application of zero (71.0%, first year and 79.3%, second year) and one cut (69.3%, first year and 75.0%, second year). There was a decrease in the production and quality of the seeds of the second cut, especially during the first year of evaluation. The total tillers, the percentage of tillers that went through the reproductive stage, and the number of reproductive tillers are the variables that are most highly correlated with seed production.

“…Known as boas práticas (best practices) cattle ranching, the system has been extensively researched and developed by the Brazilian Agricultural Research Corporation (Embrapa). It is already deployed commercially on some ranches in Brazil (16,17). It is not yet widely cost competitive due in part to high upfront costs (see SI Text for further details on semi-intensive pasture management systems).…”

This study examines whether policies to encourage cattle ranching intensification in Brazil can abate global greenhouse gas (GHG) emissions by sparing land from deforestation. We use an economic model of global land use to investigate, from 2010 to 2030, the global agricultural outcomes, land use changes, and GHG abatement resulting from two potential Brazilian policies: a tax on cattle from conventional pasture and a subsidy for cattle from semiintensive pasture. We find that under either policy, Brazil could achieve considerable sparing of forests and abatement of GHGs, in line with its national policy targets. The land spared, particularly under the tax, is far less than proportional to the productivity increased. However, the tax, despite prompting less adoption of semi-intensive ranching, delivers slightly more forest sparing and GHG abatement than the subsidy. This difference is explained by increased deforestation associated with increased beef consumption under the subsidy and reduced deforestation associated with reduced beef consumption under the tax. Complementary policies to directly limit deforestation could help limit these effects. GHG abatement from either the tax or subsidy appears inexpensive but, over time, the tax would become cheaper than the subsidy. A revenue-neutral combination of the policies could be an element of a sustainable development strategy for Brazil and other emerging economies seeking to balance agricultural development and forest protection.agricultural intensification | land sparing | climate policy
