The original article unfortunately contained mistakes.

• Nitrogen Use Efficiency or NUE should read as Nitrogen Efficiency or NE throughout the text (except in Abstract, paragraph 2, line 3 and paragraph 4, line 6), as well as in Table 1 and Fig. 1.

• On page 3 of the original article, paragraph 3, the formula ‘NUE =shoot weight/total nitrogen content of shoot’ should read as ‘NE = [Biomass accumulation at low N level/Biomass accumulation at high N level] × 100’.

• On page 3 of the original article, 5th paragraph, lines 16–17, “nanomoles NO ^-₂ produced per milligram protein per minute” should read as “micromole NO ^-₂ produced per gram dry weight per hour”.

• On page 3 of the original article, 6th paragraph, lines 15–16, “micromoles NO ^-₂ utilized per milligram protein per hour” should read as “micromole NO ^-₂ utilized per gram dry weight per hour.”

• On page 3 of the original article, 8th paragraph, lines 10–11, “micromoles γ-GH formed per milligram protein per minute” should read as “micromoles γ-GHA formed per gram dry weight per minute.”

• On page 4 of the original article, 6th paragraph, lines 3–4, the sentence “six cultivars varied from 0.008 to 0.43 mM,” should read as “six cultivars varied from 0.008 to 0.043 mM,”.
