“…This study and several others (Silber et al, 1997;Prassad and Dennis, 1986;Montarone and Zieggler, 1997) have shown the need for and the beneficial effects of fertilizer application in proteas. During soil and plant sampling in this study, most farmers confirmed that they used NPKS fertilizers and some lime in their protea orchards, with higher rates applied to the deficient plots.…”

“…Work conducted in France also suggests significant variations in nutrients among different cultivars (Montarone and Zieggler, 1997). Large differences in leaf nutrient composition were reported between Ld 'Safari Sunset' and 'Silvan Red' and P. 'Pink Ice' (Cecil et al, 1995).…”

“…Water requirements of the different species grown under soilless conditions differ (Montarone and Ziegler 1997), with P. cynaroides requiring twice the amount of water required by P. eximia. Water requirements can be deducted by knowledge of where species grow naturally, i.e., species growing in wet valleys or near water sources have higher water requirements than species preferring dry areas (Manders and Smith 1992).…”

“…Research effort has focused on the cultivation of Protea in soilless media (Montarone and Allemand 1993). This has led to clarification of the total plant uptake of nutrients for certain species and clones (Montarone and Ziegler 1997). It is obvious that differences between species exist in terms of their requirements for different nutrients ).…”

More than 1400 species have been recognized in the ancient Proteaceae family (Rebelo 1995). Their occurrence is mostly distributed between Australia with about 800 species and Africa with about 400 species with the remainder found in South America, the islands east of New Guinea, and a few species in southeast Asia, New Zealand, and Madagascar. They are broadly referred to as proteas, although we identify specific genera by their Latin names. The subfamily Proteoideae, largely found in Africa, has contributed the genera Protea, Leucadendron, and Leucospermum to floricultural trade, while the Australian Grevilleoideae has contributed Banksia and Grevillea that have found similar use in floriculture and landscaping. Other genera are still emerging in importance (Criley, 2001

“…1993; Montarone and Ziegler, 1996). If the P content of the soil is low, Proteaceae form dense clusters of roots named proteoid roots that decrease or are eliminated when P levels increase (Shane et al, 2008;Hue, 2009).…”

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.
