Resistance to ammonium toxicity in canola genotypes
Year: 2019
Type: dissertation
Abstract: Canola (Brassica napus L) is a major oil crop that is sensitive to soil ammonium concentrations. The objective of this thesis was to characterise the resistance of canola genotypes under varying soil ammonium concentrations at various growth stages, and evaluate strategies to mitigate ammonium toxicity. We identified the relative sensitivity of canola genotypes, and demonstrated that ammonium toxicity can be alleviated by increasing the proportion of nitrate in the mixed ammonium: nitrate supply, and by adding oil mallee biochar at the rate of 20 t/ha.
