The Crop Variety Sowing Guide attempts to present all the information that is necessary for you to make the best choice of variety for each of the major crops. As well as varietal characteristics and performance, it contains information on herbicide resistance, disease, agronomic factors, deliveries and marketing.

Much of the information presented this year is on the basis of the ‘Agzone’. This is an amalgamation of the traditional ‘region zone cells’which were coded H1 to L5 according to length-of-growing season zones from north to south (1 to 5) and rainfall regions, based on annual average rainfall, from west to east.

Agzones have been developed through the statistical analysis of crop performance. The results presented are based on cumulative information from the last 10 years of varietal testing, with results for new varieties based on at least 3 years data. The Agzone areas have been labelled Agzone 1 to 6 as outlined in the map on page 11.

Lupin zones have been introduced into the lupin section this year. The lupin zones replace the traditional ‘region zone cells’ and ‘Agzones’. They have been developed by considering the level of risk for biotic and abiotic stresses to lupin production. The lupin zone matrix shows these risk levels. The lupin zones are also supported by statistical analysis of lupin performance over time.
