Nitrogen uptake and Nitrogen Fertilizer Nitrogen uptake and Nitrogen Fertilizer use Efficiency (NFUE) by modern and historic wheat varieties over three growing seasons. (2016 – 2018).
Choosing genotypes with a high capacity for taking up nitrogen (N) from the soil and the ability to efficiently compete with weeds for this nutrient is essential to increasing the sustainability of cropping systems that are less dependent on auxiliary inputs. This research aimed to verify whether differences exist in N uptake and N fertilizer recovery capacity among wheat genotypes and, if so, whether these differences are related to a different competitive ability against weeds of wheat genotypes.
