Table 1. The maximum biomass and nitrogen (N) uptake of wheat and faba bean estimated by a logistic model (Eqn 1).

		Wheat			Faba bean
		Iso	Mono	Inter	Iso	Inter
Max. biomass (g plant−1)	Total	9.95	3.88	2.91	7.59	3.24
	Shoot	8.50	3.14	2.43	5.61	2.51
	Root	1.23	0.60	0.49	1.87	0.83
	Root/Shoot	0.14	0.19	0.49	0.33	0.33
Max. N uptake (mg plant−1)	Total	214.7	55.1	48.2	169.3	63.2
	Shoot	202.0	60.0	43.0	124.0	43.0
	Root	17.7	8.40	6.10	49.4	21.9

Note: A logistic model was fitted separately to the mean of three replicates of total plant, shoot and root. Iso indicates isolated plants; Mono indicates monocropped plants; Inter indicates intercropped plants.
