Effects of Sowing Dates and Seeding Rates on Nitrogen and Water Use Efficiency of Facultative Wheat
Özet
In this study, effects of different sowing dates and seeding rates on N uptake efficiency (NUE), N translocation efficiency
(NTE), agronomic efficiency (AE), physiological efficiency (PE), water use efficiency for grain yield (WUEg) and water
use efficiency for biomass (WUEb) of facultative wheat were investigated. As the average of cropping year, sowing dates
and seeding rates, N uptake efficiency (NUE), N translocation efficiency (NTE), agronomic efficiency (AE), physiological
efficiency (PE), water use efficiency for grain yield (WUEg) and water use efficiency for biomass (WUEb) values were
respectively obtained as 1.17 kg Nuptake/kg Napplied, 68.5%, 36.9 kg grain/kg Napplied, 31.2 kg grain/kg Nuptake, 5.19 kg ha–1 mm–1
and 18.04 kg ha–1 mm–1.
Nitrogen and water use efficiencies decreased with delayed sowing dates and increased with increasing seeding rates. It
is possible to maintain a high wheat yield, nitrogen and water use efficiency by increasing plant density through winter
sowing. It was concluded based on present findings that sowing date and seeding rates had significant effects on nitrogen
and water use efficiencies and winter sowing should be practiced as not to cause yield losses and high seeding rates
(575 seeds m–2) yielded greater nitrogen-water use efficiencies.
