Mean N content (% dry weight) of grain from five varieties of rye grown in 2009–2010 under different nutrient application regimes (n = 10). N content was affected significantly (p = 0.010) by an interaction between N and S.

N (kg ha−1)	S (kg ha−1)
	0	15	40
1	1.34	1.32	1.31
100	1.61	1.64	1.63
200	1.96	2.10	2.18

Standard error of the difference (SED) for comparisons: 1. Means with same N level (different S): SED = 0.046 on 27 df; LSD (5%) = 0.094. 2. Means with same S level (different N): SED = 0.053 on 24 df; LSD (5%) = 0.110. 3. All other comparisons: SED = 0.054 on 27 df; LSD (5%) = 0.111.
