N2  - A long-term factorial trial with nitrogen, phosphorus, and potassium fertilizers was started at Nuriootpa Viticultural Station, South Australia on the grape cultivar Shiraz in 1944. Results show a significant yield response to superphosphate. Long-term applications of ammonium sulphate resulted in severe reduction of vine growth and yield, and a significant lowering of soil pH. No direct response to potassium sulphate was obtained except in one year, but a positive interaction between potassium and phosphorus occurred in some years. An analysis of the components of yield in 1964 showed that the increase in yield with superphosphate was due to an increase in the number of berries per bunch. The nitrogen, phosphorus, and potassium contents of petioles were determined and related to available reference standards.
