“…There were differences of some nutrient concentrations between cultivars of Leucospermum, as well as between those of Leucospermum and Protea, confirming what the literature mentioned on this subject (Parvin 1986;Cecil et al, 1995;Montarone et al, 2003). Na presented very high concentrations, specially in the cultivar 'Succession II', a fact that Alvarez et al (2012) had pointed out for proteas.…”

Several parameters of flowering stems of two cultivars of protea Leucospermum cordifolium (Knight) Fourc ('Succession II' and 'Tango') and one of protea Protea L. (Protea susannae x magnifica 'Susara') were studied in different commercial plantations. These included length and weight measures, nutrient concentrations of detached parts (flower heads, leaves and stems), and removal of nutrients of harvested flowers. A base for fertilization was also calculated. Harvested flowers of 'Susara' removed more P, K and Cu than 'Succession II' and 'Tango', and more Ca and Fe than 'Tango'. 'Succession II' showed the highest Zn removal. The P and Cu removal by the crop of 'Susara' were significantly higher than those of both Leucospermum cultivars, while K, Ca, and Fe outputs of 'Susara' exceeded only those of 'Tango'. The nutrient top removals amounted to 4.55 g m -2 of N, 0.48 g m -2 of P, and 5.26 g m -2 of K. Data as a base to supply fertilizer to each cultivar are given, with N:P:K ratios of 1:0.08:0.87 for 'Succession II', 1:0.08:0.83 for 'Tango' and 1:0.10:1.27 for 'Susara'.

“…It is important to highlight that despite the fact that the K content was high in the soil of both cultivars, 'Tango' showed lower levels of foliar K than 'Succession II'. This supports the idea that nutrition in Proteaceae may differ within the same genus, the same species and even within cultivars of the same species (Claassens, 1986;Montarone et al, 2003;Hernández et al, 2008).…”

“…Fifteen years later, Montarone (2001) insisted that this information was still insufficient. This is understandable in light of the fact that nutrient needs of Proteaceae differ by genus and even by species (Claassens, 1986;Montarone et al, 2003). The latter authors studied the nutrition requirements of the genera Protea and Leucospermum and found that Leucospermum has a mineral uptake rate twice that of Protea.…”

Two cultivars ('Succession II' and 'Tango') of Leucospermum cordifolium were studied over three years in commercial plantations with optimum yields located on subtropical La Palma Island (Canarian Archipelago). Four foliar samplings were taken per year to determine the evolution of the N, P, and K contents over time and to determine the optimal month for foliar standard sampling. Foliar chlorophyll activity and the foliar standard concentrations of macro-and micronutrients were determined. Soil samples were also taken. Both cultivars developed well in soils with acid and slightly acid pH, low and high organic matter content, and in some cases, high available P concentrations, though Proteaceae is generally considered P sensitive. Chlorophyll activity correlated neither with foliar nutrient levels nor with leaf greenness. The foliar N content reached a maximum of 17.0 g kg -1 in the cultivar 'Succession II' and 17.2 g kg -1 in 'Tango', whereas the maximum P and K levels were lower in 'Tango' than in 'Succession II'. The greatest stability of the concentrations of these nutrients occurred in September; therefore, this month was chosen for performing foliar standard sampling. The standard ranges of N, K, Ca and Mg were higher in 'Succession II', while Fe, Mn, and Zn were higher in 'Tango'. The P and Cu standard ranges were similar in both cultivars.

“…From the results of numerous studies mentioned above,it can be established that the inconsistencies in the causes and alleviation of P toxicity in Proteaceae may be due to the fact that different genera and species of Proteaceae react differently to P, where in one species, a certain mineral nutrient may alleviate P toxicity, and in another species, it may aggravate it. Montarone et al (2003) confirmed in their study that large differences in mineral requirements exist between cultivars belonging to the same Proteaceae genus, with even larger differences between genera.…”
