Summary

Leaf water potentials of Navy bean plants receiving different irrigation treatments during the three main developmental stages were measured at dawn throughout two growing seasons in a field experiment conducted in the Inglewood irrigation area of Queensland during the summers of 1971 and 1972. Integrated seasonal values of leaf water potential were derived from the measurements for each treatment, weighted in different ways, and the values so obtained correlated with those of yield for the two seasons. The weather during the two growing seasons differed markedly and there were also marked differences in the method of integrating the leaf water potential measurements which gave the highest correlation with yield in the two seasons. In 1971, a season with less negative potentials and lower yields, the highest correlation (r= −0.85) was obtained with a linear relationship in which the leaf water potential duration (stress area) during the preflower, flowering and pod development stages were weighted with the following factors, 1.0, 2.0 and 0.75. In 1972, when more negative values of stress and higher yield levels were recorded, the highest correlation with yield (r= −0.92) was obtained with a quadratic equation in which the stress area values during the same three development stages were weighted by factors of 0.5, 3.0 and 2.0 respectively. Stress area models were also used to obtain seasonal values for correlation with the following three growth parameters: crop growth rate, leaf area index and leaf area duration. The highest correlation coefficients obtained for the 1972 growing season were −0.80, −0.72 and −0.73 respectively.
