Abstract: The initial experiment was designed to compare the responses to P and Zn fertilisers of 'Pisum sativum' L. var. Dundale and 'Triticum aestivum' var. Sunco grown on a grey clay of low P status. P was applied at four rates (0, 10, 20 and 40 kg P/ha) and Zn at two rates (0 and 5 kg Zn/ha). For peas, there was a significant response in shoot dry weight and P concentration when P was applied at 20 and 40 kg/ha whereas wheat responded at 10 kg/ha and above. Zn fertiliser increased the node number in peas and Zn concentration in both peas and Wheat. Any phosphorus-zinc interaction effects were small and variable compared to the main P and Zn effects. Following this experiment a sequence of experiments was conducted to compare the responses of pea to P fertiliser application under field and glasshouse conditions. Since the response of wheat to P application in Australia is well recognised, unlike that of peas for which little data is available, it was decided that further experiments be pursued only with peas.
