Abstract

HENSCHKE, M., ST. SZCZEPANIAK and E. WOJCIECHOWSKA, 2015. The effect of Osmocote fertilisers on growth and nutrient status of Anemanthele lessoniana (Steud). Veldkamp. and Bouteloua gracilis (Kunth). Lag. ex Griffiths. Bulg. J. Agric. Sci., 21: 605–610

The increasing importance of ornamental grasses in horticultural cultures results in the need to determine their cultivation requirements. A particularly essential role is played by the selection of fertilisers and specification of nutrient requirements. An experiment on the effect of Osmocote fertilisers on growth and nutrient status of Anemanthele lessoniana (Steud). Veldkamp. and Bouteloua gracilis (Kunth). Lag. ex Griffiths was conducted in the years 2008 – 2009. The differentiating factors included the type of fertiliser, i.e. Osmocote Exact Standard 16:11:11 and Osmocote Exact High Start 11:11:19, and fertiliser doses of 2 and 4 g·dm-3. In the culture of Anemanthele lessoniana and Bouteloua gracilis it is recommended to apply Osmocote 11:11:19 at a dose of 4 g·dm-3. The best quality plants in their aboveground parts contained the following amounts of macronutrients and sodium [%]: Anemanthele lessoniana – N - 1.54, P – 0.35, K – 2.10, Ca – 0.61, Mg – 0.14, Na – 0.10, while in Bouteloua gracilis it was – N – 1.75, P – 0.59, K – 2.31, Ca – 0.91, Mg – 0.36 and Na – 0.05, respectively.

Key words: ornamental grasses, slow-release fertilizer, leaf length, fresh weight, macronutrients
