Essential oil production of lemongrass (Cymbopogon citratus) under organic compost containing sewage sludge

Abstract: A B S T R A C TOne of the main urban polluting agents are the sewers, which even with proper treatment end up generating a polluting waste, the sewage sludge. One of the options for the disposal of this sludge is the use in agriculture, due to its high content of organic matter and nutrients. This study aimed to use urban sewage sludge for lemongrass cultivation and essential oil production. The plants were grown in soil containing different organic compost doses (0, 5, 10, 20, 40 and 60 t ha -1 ), formed… Show more

“…The results regarding chlorophyll pigments confirmed that upper parts of plant leaves could be a good material for infusions while the lower parts of a slight concentration of pigments -as a flavour and aroma enhancer in meals. Both d Ávila et al 14 and AL-Joburi 9 have reported even 10-fold higher values of all pigments analysed chlorophyll a as well as b ; however, their determinations were carried out in fresh leaves of C. citratus while in our study dry plant material was used. Unfortunately, the authors mentioned above did not determine the content of pigments in the individual parts of the plant.…”

“…As plantas de aroeira cultivadas em lodo (T3, T4 e T5) apresentaram maiores valores médios de clorofila total em comparação a 100% T e 100% A. Mudas de aroeira cultivadas com adição de biossólido e adubação apresentaram maiores índices de clorofila quando comparadas àquelas sem adição de biossólido [36]. D'Ávila et al (2016) [37] observaram uma elevação nos teores de clorofila em Cymbopogon citratus na medida em que houve o aumento das doses de lodo empregado no substrato para essas plantas. Dessa forma, é provável que o lodo seja capaz de disponibilizar mais nitrogênio e magnésio para as plantas, de modo que para os tratamentos que o utilizaram na composição do substrato apresentaram maior síntese de clorofila.…”
