摘要

Australia wheat production for 2007/08 is forecast at 13.5 million tons, down 7.5 million or 36 percent from last month, but up 3.6 million or 36 percent from last year. The area forecast is 12.2 million hectares, down 0.8 or 6 percent from last month, but up 1.0 million or 9 percent from last year. Seasonal conditions have been variable across the major cropping regions of Australia. Since major sowing operations commenced in May, periods of dryness have plagued the Australia wheat producing states at various times. September precipitation is the most important factor for determining Australia wheat yield and was far below average for all wheat areas with the exception of Western Australia. In the largest producing state of Western Australia, an unusually dry start to the season delayed sowing operations until substantial rainfall occurred during July. August conditions were mostly warm accompanied by low soil moisture reserves. Substantial September rainfall significantly benefited Western Australias winter grain crop. In the southeastern producing states of Victoria and South Australia, crop conditions declined despite scattered rains during the past month. In the second largest producing state of New South Wales an abnormally dry September severely reduced potential yield with virtually no rain received in the wheat belt. Persistent dryness and lack of subsoil moisture in a major portion of Australias wheat region contributed to an estimated 26-percent drop in wheat yield from the five-year average. The estimated yield of 1.11 tons per hectare is the third lowest in the past ten seasons. The two lowest yields occurred in the severe drought years of 2002/03 and 2006/07. Currently, additional rainfall is needed in all growing states to sustain the current production potential.
