- Abstract
This study aimed to analyze the effect of organic fertilization on the growth and on biomass production of citronella grass (Cymbopogon nardus) as well as evaluating the effect citronella grass essential oil and of the citronellal compound in inhibiting the mycelial growth of the Didymella bryoniae fungi. To evaluate the effect of organic fertilization on the growth of citronella grass, the experiment was installed in a block randomized design in subdivided plot scheme. The plots consisted by four doses of organic cattle manure (0, 3, 6 and 9 Kg hole-1) and the subplots by five sampling times (80, 108, 136, 164, 192 days after transplant). To evaluate the effect of citronella grass essential oil in inhibiting mycelial growth of D. bryoniae, the experiment was installed in a completely randomized design in a factorial scheme. The treatments consisted of five aliquots (5, 10, 15, 20 and 25 μL) of essential oil of citronella grass and citronellal compound in five sampling times. The treatment of organic fertilization 9 Kg hole-1 exhibited the highest values in all variables in the last sampling time. A greater effect of inhibition of mycelial growth was obtained using citronellal when compared with the essential oil. In the aliquot of 25 μL of citronellal was observed total inhibition of mycelial growth of the D. bryoniae fungi.
