| Popis: | SummaryThe use of controlled-release fertiliser (CRF) has been identified as a best-management practice because CRFs supply localised nutrients to the surrounding substrate over a period of time, and so can reduce the amount of nutrient that is leached from the pot. However, no information is available regarding the application of CRF during plant production, and how that can affect the subsequent garden performance of a crop. The objective of this research was to evaluate the effect of CRF, applied at the time of plug planting, on the finished quality and garden performance (post-production) of impatiens (Impatiens wallerana Hook. f. ‘Xtreme Scarlet’) plants. Plants were fertilised with a water-soluble 20:4.4:16.6 (w/w/w) N:P:K fertiliser (WSF), applied at each irrigation event at a rate of 150 mg l–1 N, or with a 16:3.9:10 (w/w/w) N:P:K CRF with either of two longevities (5 – 6 or 8 – 9 months) at a rate of 6.8 kg m–3. Impatiens plants were grown in a greenhouse and transplanted to the field, where no f... |
