Nitrogen Fertilizer Rate and Cultivar Interaction Effects on Nitrogen Recovery, Utilization Efficiency, and Agronomic Performance of Spring Barley
Table 2
values from the analysis of variance for the effects of N rate and cultivar on grain yield and nitrogen use efficiency traits in spring barley. Year, replications within year, and their associated interactions were considered random effects.

NUE: nitrogen use efficiency, grain yield per unit of available N (soil N + applied); Total N uptake: the total N uptake in the biomass at maturity; UTE: nitrogen utilization efficiency, final grain yield per unit of N uptake; BPE: biomass production efficiency, biomass yield per unit of N taken up; HI: harvest index, the ratio of grain yield to biomass at harvest maturity; grain N yield was grain yield × grain N concentration. |
