Abstract

Efficient nitrogen (N) management is crucial for sustainable sorghum production. Biological Nitrification Inhibition (BNI), driven by root exudates like sorgoleone, suppresses nitrifying bacteria, reducing nitrogen losses and improving soil health. A three-season study with 19 sorghum genotypes across four nitrogen regimes showed that lines with high sorgoleone production achieved similar grain and biomass yields at 50% and 100% nitrogen levels, indicating better nitrogen-use efficiency (NUE) and less fertilizer reliance. To explore the genetic basis of these traits, mapping populations are being developed, and two SNPs linked to sorgoleone production have been identified for marker-assisted breeding. These findings highlight BNI's potential as a climate-smart strategy to improve sorghum productivity and sustainability.
