Abstract:
A greenhouse experiment was conducted to establish the optimal fertilization management for Leucadendron 'Safari Sunset'. Adding fertilizers or raising phosphorus concentration increased yield and improved plant growth. Root weight increased as nutrient levels rose. Clusters of proteoid roots were present all along the root system of tap-water-irrigated plants, only few proteoid roots developed on plants irrigated with complete nutrient solution when only P was omitted, and none were developed in any of the other treatments. Elevating the total nutrients or P concentrations increased N and P concentrations in the plants. The calculated N and P concentrations in mature leaves required to achieve maximal shoot weight were 33.1 and 10.7 g kg'1 dry matter, respectively. The present study demonstrates that as long as sufficient amounts of micronutrients are provided through the irrigation solution, addition of 20 mg I'1 P improves 'Safari Sunset' growth without indication of toxic symptoms that could be attributed to an excess of P.
