摘要: Abstract In the Mediterranean farming systems of Western Australian wheatbelt, crop yields are influenced primarily by amount and distribution rainfall soil's capacity to hold moisture. The wheatbelt's growing season varies in range 200–400 mm (average) plant available water holding (PAWC) soils is generally 40–140 mm range. grain yield wheat sensitive this combination small storage capacity. study, we explore relationship between PAWC using a simulation modelling analysis field data. Crop soil properties were monitored detail at 17 locations (PAWCs 43–131 mm) across six seasons (1997–2005). also simulated APSIM simulator (RMSE = 311 kg/ha) evaluate long-term 106 years historical climate varied with season, two important factors emerged: (1) for PAWC impact on was reduced late rainfall, magnified season. Six distinct types different yield–PAWC relationships identified season-specific management strategies that exploit within-field variation developed manage spatial field.
