Ginger was grown to maturity with five levels of applied nitrogen in a subtropical environment at Beerwah, Queensland, Australia. Destructive harvests were taken on 10 occasions and measurements made of fresh weight and dry weight of rhizomes and shoots. Rhizomes were classified according to order of branching, and the numbers of shoots arising from each branch order determined. Leaf numbers were also recorded in two of the treatments. Fertilizer nitrogen significantly increased the number of third order shoots and fourth order rhizome branches, and the total yields of shoots and rhizomes. A rate of application of 200-300 kg N/ha was required for maximum yield. Nitrogen use efficiency decreased with increasing rate of nitrogen application.
