Levels of N as coated urea as affecting upland rice production.

The objective of this field research was to determine the effect of N rates applied in the form of coated urea in the grain yield of upland rice

Nitrogen management as affecting plant nutrition and yields of super early cycle genotypes of common.

The aim of this study was to measure yield components and grain yield of super early genotypes of common bean as affected by timing of N fertilization.CONAF

Seed inoculation with diazotrophic bacteria as affecting upland rice yield.

The objective was to determine the effect seed inoculation with strains of Azospirillum spp. in the plant biomass, foliar nutrient concentration, yield components, grain yield and nutrient concentration in grains of upland rice under no-tillage systems in a Cerrado Region.Editors: Andreas Carstensen, Kristian Holst Laursen, Jan Kofod Schjorring

Antecipação da adubação nitrogenada de cobertura do arroz de terras altas em sistema plantio direto.

Um experimento de campo está sendo conduzido na Fazenda Capivara da Embrapa Arroz e Feijão com o objetivo de avaliar o efeito da antecipação da adubação nitrogenada de cobertura no desenvolvimento e produtividade de arroz de terras altas (Primavera CL) cultivado em SPD, utilizando diferentes fontes de N

Nitrous oxide fluxes from different nitrogen sources applied in upland rice in the cerrado goiano.

Nitrous oxide (N2O) is an important greenhouse gas, despite its low concentration in the atmosphere. It stands out due to the persistence of its molecule in the atmosphere and to its high global warming potential. There is need to spread technologies that reduce the production of this gás. To this end it is necessary to investigate the different marketed nitrogen (N) sources, such as the protected ureias and in combination with other components (such as zeolites) that may contribute to reduce the emission of N2O, being more efficiently used by the plants.Coordenador Roberto Giolo de Almeida.
