The aerobic rice experiments (ARE) with two water management practices and two nitrogen fertilizer application rates. The data from the treatments highlighted in bold were used for calibration, and the remaining treatments were for validation.

N applied		N1: 225 kg N ha−1		N2: 300 kg N ha−1
Year		Y1: 2003	Y2: 2004	Y1: 2003	Y2: 2004
Water management	W1: Irrigated every 6–24 days between emergence and flowering to ensure the soil water potential at 15 cm depth was ≤40 kPa.	W1N1Y1	W1N1Y2	W1N2Y1	W1N2Y2
	W2: 3 irrigations from emergence to panicle initiation, and one additional irrigation between panicle initiation and flowering.	W2N1Y1	W2N1Y2	W2N2Y1	W2N2Y2
