The various factors that affect the yields of chickpea and wheat (as benchmark) in New South Wales, Australia were studied in 2002. Data on plant available water (PAW) and crop yields were collected from 20 farms (12 for chickpea and 8 for wheat) in the northern part of the region. The crops were selected based on their good performance despite drought conditions. The variation in chickpea yields was mostly attributed (90%) to PAW. The effects of disease, insect and weed problems on yield variation were less pronounced. Wheat was more effective than chickpea in soil water utilization. As PAW decreased, water use efficiency (WUE) remained relatively constant for wheat, but harvest index and WUE declined for chickpea. Soil moisture stress was the main yield-limiting factor cited by farmers, but poor or delayed emergence, and frost and harvesting losses were also mentioned. The high harvesting loss recorded for chickpea (average of 0.23 t/ha or 20%) indicated that harvesting loss was the most significant problem in chickpea production. Tillage was identified as the major factor that affected soil water storage. Burning and cultivation also caused a substantial reduction in soil water.
