For a number of years the Australian grain industry has produced grain protein results below desired levels in a significant proportion of the wheat crop. This can have a negative impact on grower’s financial returns and in the longer term damage Australia’s position in premium, milling-quality export markets.
Over the last couple of months I have become involved in a discussion about the nitrogen response of the wheat variety EGA Gregory in relation to its yield and grain protein when compared to other similar varieties.
Take Home Message There are numerous factors both manageable and uncontrolled that significantly influence the grain yield and protein outcome of crops. To be able to increase the probability of reaching a grain yield and protein target it is important to have and understanding of processes important to the final outcome. This may provide the ability to respond appropriately to those factors that are manageable and minimise the risk of the uncontrolled having significant influence.
