Resumo: The objective of this work was to analyse N accumulation, translocation, postanthesis uptake and utilization efficiency under two tillage systems (moldboard plow and chisel plow) and different fertilizer types in two cultivars of bread wheat (Buck Pronto and Buck Charrúa). The N fertilizer treatments were: without N, 90 kg ha-1 at sowing as urea, 90 kg ha-1 at sowing as ammonium nitrate, 45 kg ha-1 at sowing and 45 kg ha-1 at tillering as urea and 45 kg ha-1 at sowing and 45 kg ha-1 at tillering as ammonium nitrate. Difference in N accumulation between tillage systems (chisel accumulated 18 kg ha-1 more than moldboard) was found, but this did not correspond to improvement of grain N content by remobilization or by postanthesis N uptake. Fertilization, independently of the type and time of application, increased N accumulated (50 kg ha-1 in average) and N remobilized to the grain, but N contribution to grain arising from postanthesis uptake did not improve. Cultivars presented differences in N accumulated and in N contribution to grain by remobilization and postanthesis uptake. Nitrogen utilization efficiency depended on the tillage systems and the fertilization treatments.–

Los tratamientos de fertilización fueron: testigo sin el agregado de N, aplicación de 90 kg ha-1 de N como urea a la siembra, aplicación de 90 kg ha-1 de N como nitrato de amonio calcáreo a la siembra y aplicación de N como urea y como nitrato de amonio calcáreo en dosis de 45 kg ha-1 a la siembra más 45 kg ha-1 a fin de macollaje, respectivamente. Se encontraron diferencias en el N acumulado entre sistemas de labranzas; con cincel se acumuló 18 kg ha-1 más que bajo reja, pero esto no se tradujo en el porcentaje de N contribuido al grano por removilización ni por absorción postantesis. La fertilización aumentó el N acumulado en un promedio de 50 kg ha-1. A su vez provocó un aumento en la contribución al grano del N removilizado, pero no mejoró el aporte del N absorbido postantesis, ni aún en la aplicación en dos momentos. Los cultivares presentaron diferencias en el N acumulado y en el porcentaje aportado al grano por removilización y absorción postantesis. La eficiencia de utilización del N dependió de la labranza y de la fertilización.The objective of this work was to analyse N accumulation, translocation, postanthesis uptake and utilization efficiency under two tillage systems (moldboard plow and chisel plow) and different fertilizer types in two cultivars of bread wheat (Buck Pronto and Buck Charrúa).
