MARCH -- APRIL 2008 GROUND COVER 25 Northern agriculture those forays. Early northern attempts at major agriculture cropping were poorly researched, used technology from different environments, and despite what were regarded as big investments, suffered from insufficient infrastructure, knowledge and resources. Should historical mistakes be considered a valid criteria for stopping future development? For example, from 20 years of research, CSIRO has developed a blueprint for profitable cotton production in northern environments. Varieties suited to northern day lengths and temperatures, and resistance to pests (especially Helicoverpa armigera) have been developed, as well as agronomy practices suitable for the region. More immediately, the main focus for many northern landholders is improving land management so that cattle numbers can be increased sustainably. Crops could assist this, as well as provide income diversity. A reliable northern grains industry also adds to Australia's overall reliability as a grain producer; a real issue in the face of climate uncertainty and lower rainfall in southern areas. In particular, crops such as sorghum and maize increase the flexibility of agriculture in the north. If seasons are favourable, these crops can be taken through to grain. If they dry off early and stored soil moisture runs out, they can be used for green chop, hay or silage, or grazed-off. Rainfall is mainly between late November and the end of March. In the lower northern rainfall areas (450 to 550mm per year) it may be feasible to crop in the 'wet season', especially on well-drained soils. In the upper northern region, maximum summer temperatures are similar to summer-cropping temperatures in north- west NSW and south-west Queensland. Winter temperatures are much warmer and could be conducive to summer crops. Further south (within the northern region), summer maximum temperatures tend to be two to three degrees higher than north-west NSW and south-west Queensland grain areas. However, Australian sorghum and maize breeders have sourced germplasm from hot overseas environments and are developing varieties with greater heat tolerance.
