Nitrous oxide emission (N2O) in the cultivation of sugar cane

The variety cultivated is key to reducing the N footprint2O.

Project 7 of the Omics Program: Productive Sustainability

The effect of the cultivated variety on N emission was evaluated2O and the yield of the sugarcane crop under a dose of 184 kg N ha-1. The above allowed us to estimate the footprint of the N2Or for each variety and contrasting agroecological zone. In general, no relationship was identified between sugarcane variety and cumulative N emission.2Or from the soil due to the multiple factors that influence the N assimilation dynamics of the plant.
