Nitrogen Fertilizer Rate and Cultivar Interaction Effects on Nitrogen Recovery, Utilization Efficiency, and Agronomic Performance of Spring Barley
Figure 1
Grain yield of three spring barley cultivars grown under three rates of N fertilizer (0, 50, and 100 kg ha−1) at Lacombe, Alberta, Canada, during 1994 to1996. values indicate significance of linear or quadratic responses to N rate as determined from orthogonal contrasts, NS indicates nonsignificant differences at .
