Table 2. Times and rates of maximum instantaneous biomass production and nitrogen uptake by wheat and faba bean estimated by a logistic model (Eqn 1).

			Wheat			Faba bean
			Iso	Mono	Inter	Iso	Inter
Biomass	Time (d)	Total	50	45	41	42	33
		Shoot	48	41	39	40	30
		Root	45	37	35	37	29
	Rate (g plant−1 d−1)	Total	0.40	0.13	0.10	0.22	0.08
		Shoot	0.35	0.11	0.09	0.18	0.08
		Root	0.05	0.02	0.02	0.05	0.02
N uptake	Time (d)	Total	40	26	28	33	15
		Shoot	42	30	28	37	15
		Root	37	30	27	28	21
	Rate (mg plant−1 d−1)	Total	8.66	2.74	2.12	4.22	2.52
		Shoot	7.75	2.40	1.86	2.82	1.99
		Root	0.77	0.44	0.29	1.50	0.56

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.
