nitrogen status

Catalogue: GRDC Media
New research has revealed that hybrid canola varieties are potentially a profitable break crop option for Western Australia's low rainfall zones and that growers in these areas can make savings by delaying decisions about nitrogen applications for these varieties in particular... DAFWA senior research officer Mark Seymour said the results, presented at this year's Regional Crop Update at Salmon Gums, indicated that hybrid RR lines could provide opportunities for growers in the region to use low rates of nitrogen at seeding and then add more nitrogen, as needed, to reach optimal yield... Mr Seymour said the trial highlighted the importance of assessing the nitrogen status of the crop and ensuring that canola was not over-fertilised in low rainfall areas, as the reduction of oil content levels with increased nitrogen could also lead to big discounts...

Nitrogen benchmarking for better management.. "Despite the importance of nitrogen for crop yield and its incidence in the variable costs of farm business, there is no established benchmark to assess the nitrogen status of crops," Dr Sadras explains... "The nitrogen nutrition index is the only method to unequivocally measure the nitrogen status of the crop, and removes much of the uncertainty related to soil and seasonal conditions that are typical of conventional crop diagnostics," Dr Sadras says...

"Despite the importance of nitrogen for crop yield and its incidence in the variable costs of farm business, there is no established benchmark to assess the nitrogen status of crops," Dr Sadras explains... Dr Sadras says the direction of the plant breeding industry - breeding for yield - is probably shifting the biomass-nitrogen balance in crops, so agronomic practices, including fertilising, need to be adjusted to capture the potential yield and protein content of new germplasm...
