14. Development and application of a bioeconomic efficiency index for beef cattle production in Rio Grande do Sul, Brazil
An index was developed to estimate the bioeconomic efficiency of production systems, identifying alternative scenarios that could improve their efficiency, and building isoefficiency relations in beef cattle production systems in Rio Grande do Sul. The concept of return on investment was used to develop the indicator. Scenarios regarded as efficient showed v

15. Diversity of 16S rRNA genes from bacteria of sugarcane rhizosphere soil
Sugarcane is an important agricultural product of Brazil, with a total production of more than 500 million tons. Knowledge of the bacterial community associated with agricultural crops and the soil status is a decisive step towards understanding how microorganisms influence crop productivity. However, most studies aim to isolate endophytic or rhizosphere bac

19. VARIABLE-RATE NITROGEN FERTILIZATION WITH N-SENSOR IN MAIZE AND WHEAT / ADUBAÇÃO NITROGENADA À TAXA VARIADA COM O N-SENSOR NAS CULTURAS DO MILHO E TRIGO
Most tropical and subtropical soils present insufficient availability of nitrogen (N) to meet the demand of maize and wheat in order to obtain high yields. The N in plants can be evaluated through the use of sensors of active optical spectrometry, on which stands the N-Sensor, equipment able to determine the N rate to be applied in coverage in real-time. The
