Fruit composition of oil, oil + proteins, and other solids as affected by N levels in the field experiment.

N level	Oil		Protein		Oil + proteins		Additional solids
N0	46.1	a	3.3	b	49.4	a	50.6	b
N75	43	ab	4	b	47	ab	52.9	ab
N150	40	b	4.9	a	44.9	b	55.1	a
N300	39.7	b	5.4	a	45.1	b	54.8	a
Linear	***		***		**		**
Quadric	***		***		**		**

Each point is an average of 28 measured trees in 2014 and 2015. Linear and quadric regression were fitted, and p-value is presented below (*p<0.05; **p<0.001; ***p<0.0001). Values labeled with different letters indicate significant differences between treatments, following Tukey HSD test.
