The camelina plant height in centimeter per plant as influenced by different rates of NP fertilizer and agroecology. 0N0P stands for 0 kg/ha of nitrogen and 0 kg/ha of phosphorous fertilizer, and similarly for 30N10P, 60N20P, 90N30P, 120N40P and 150N50P. The data are the means of three replicates. Differing letters show significant differences in pairwise comparisons (Tukey’s test, P < 0.05).
