Abstract

Current varieties of narrow-leafed lupin (Lupin angustifolius L.) are poorly adapted to alkaline and calcareous soils found commonly throughout the south-estern Australian cropping zone. A pot experiment compared the growth of Lupinus angustifolius cv. Gungurru with L. pilosus P20954 in a range of soils collected throughout South Australia. The soils displayed a range of texture (clay, 3-82%), pH (1: 5 soil : H2O, 7.0-9.6), and calcium carbonatecontent (CaCO3, 0-47%). Potting mix (pH 5.8) was used as the control. The plants were grown for 7 weeks with weekly measurements of chlorosis score and leaf number. At harvest, dry weights were recorded and the youngest fully expanded leaves were analysed for nutrient concentrations. The line P20954 grew much better in all the soils than Gungurru in terms of plant dry weight relative to the control soil, this being particularly evident in the calcareous soils. Chlorosis score correlated highly with shootdry weight for Gungurru, but not for P20954. The main soil factor contributing to the chlorosis score of Gungurru was CaCO3 content, whereas none of the soil factors significantly affected P20954, although in Weeks 2 and 3 chlorosis score correlated with CaCO3 content. The dry weight of Gungurru was affected by a combination of factors including clay content, pH, and CaCO3 content, whereas the dry weight of P20954 was affected by most of the soil factors measured. The dry weight of P20954 was positively correlated withaluminium and magnesium concentrations. Concentrations of all nutrients were above critical levels for both genotypes grown in all soils. The resultsindicate that L. pilosus has the potential to be grown in areas where current varieties of L. angustifolius are poorly adapted.
