As forrageiras desempenham papel primordial na obtenção de produtos de alto valor biológico no Brasil. Diante disso, tem-se destaque o gênero Brachiaria (sinonímia Urochloa) por sua rusticidade e adaptação ao clima e solo naturais. Porém, a espécie apresenta dificuldade de germinar tanto em campo, como em laboratório, devido à dormência, afetando na uniformidade da pastagem. Os testes comumente utilizados para ...
In this study, the stimulatory effects of application of glyphosate herbicide coupled with manganese sulfate (8%) foliar fertilizer on the production and bromatological characteristics of Brachiaria brizantha ‘Marandu’ were evaluated. The experiments were performed using randomized complete block design with a 5×4 factorial scheme in plots subdivided over time (across four evaluations) with four repetitions, to...
The drift of the herbicide glyphosate, used for desiccating crops or controlling weeds, can result in growth-promoting or non-target plant development effects. Thus, it is possible to use the compound to increase the biomass of forage through the hormone effect. The objective of this study was to evaluate the effects of sublethal doses of glyphosate on the production of Urochloa brizantha cv. Marandu (Marandu g...
Glyphosate drift in plants that are not resistant to the herbicide molecule can result in stimulation to certain biological features, characterizing the phenomenon of hormesis. On this basis, productive and chemical traits were evaluated in marandu grass, in a simulation of the drift effect, using sublethal doses of the herbicide glyphosate. The experiment was in laid out in a randomized-block design with split...
The agricultural industry is the main emitter of methane (CH4) and nitrous oxide (N2O), gases that each have a global warming potential that is greater than that of CO2 by 23 and 298 times, respectively. On a global scale, enteric fermentation from ruminant animal production (especially of cattle and sheep) is responsible for between 21% and 25% of total anthropogenic CH4 emissions. The search for effective, si...

A utilização de compostos orgânicos é importante na produção de hortaliças,uma vez que melhora as propriedades do solo e recicla resíduos orgânicos.O presente trabalho teve por objetivo avaliar o desempenho de cultivaresde alface com aplicação de fertilizantes minerais e orgânicos. O experimentofoi conduzido em campo, em Ariquemes (RO), de agosto a outubro de 2012.O delineamento experimental foi em blocos casua...
