The Effect of Leaf Nutrition with Hortigrow on the Content, Yield and Chemical Composition of the Essential Oil from Common Basil of ‘Trakia’ Cultivar
Journal Title: Scientia Agriculturae - Year 2015, Vol 9, Issue 3
Abstract
The aim of the study was to establish the effect of the leaf nutrition with Hortigrow on the content, yield and chemical composition of the essential oil distilled from dry leaf and stems biomass and flower spikes of common basil, ‘Trakia’ cultivar. The experiment was carried out in the period 2007-2009 on the Training-and-Experimental fields of the Agricultural University – Plovdiv, set by the block plot design in four replications, the plot size being 20 m2. The following variants were studied: 1) Control; 2) Hortigrow with a N:P:K ratio 30:20:10; 3) Hortigrow with a N:P:K ratio 20:20:20; 4) – Hortigrow with a N:P:K ratio 5:50:20, applied three times during the vegetation period before flowering of the second-order branches after basic fertilization with 160 kg/ha of nitrogen (applied three times) and irrigation to 80-100% of water holding capacity.The results showed that the application of Hortigrow had a negative effect on the essential oil content. Nevertheless, higher essential oil yields were obtained in the treated variants thanks to the higher yield of dry matter, leading to a higher yield of essential oil per unit of area. The major components of the essential oil distilled from dry leaf and stem biomass and flower spikes are linalool, limonene, methyl chavicol and methyl cinnamate.
