“…According to Meira et al (2013), water deficit has direct effects on vegetative growth, biomass production and contents of secondary metabolites. The water deficit favored the effect of the irrigation depths on chamomile development (Figures 2, 3 and 4), directly interfering with the content of flavonoid and essential oil.…”

A B S T R A C TThe therapeutic efficacy of herbal medicines and pesticides has increased the need to define cultivation parameters for medicinal plants. The objective of this study was to evaluate the production of essential oil and flavonoids of chamomile under irrigation levels and organic fertilizer doses. The experiment was conducted in the experimental area of the Campus II of the University of Western São Paulo, in the city of Presidente Prudente, SP, Brazil. The experimental design was a randomized block in triple factorial (6 x 2 x 3), corresponding to irrigation depths (150, 100, 75, 50, 25 and 0% of the reference evapotranspiration (ETo)), organic fertilizers (poultry manure and cattle manure) and the fertilizer doses (0, 3 and 5 kg m -2 ), with four replicates. The following variables were evaluated: capitulum dry matter, and content and yield of essential oil and flavonoids. For the tested conditions, it is recommended to use 5 kg m -2 poultry manure and water depth equivalent to 150% ETo for the production of essential oil and flavonoid.Irrigação e adubação orgânica na produção de óleo essencial e flavonoides em camomila R E S U M O A eficácia terapêutica de fitoterápicos e fitofármacos tem aumentado a necessidade de definir parâmetros de cultivo para plantas medicinais. O objetivo do presente trabalho foi avaliar a produção de óleo essencial e flavonoides da camomila quanto a lâminas de irrigação e doses de adubo orgânico. O experimento foi conduzido em área experimental do Campus II, da Universidade do Oeste Paulista, na cidade de Presidente Prudente, SP, Brasil. O delineamento experimental foi em blocos ao acaso em esquema fatorial triplo (6 x 2 x 3), sendo a lâmina de irrigação (150, 100, 75, 50, 25 e 0% da evapotranspiração de referência (ETo)), o adubo orgânico (esterco de aves e esterco bovino curtido) e a dose do adubo (0, 3 e 5 kg m -2 ) e quatro repetições. Foram avaliados a massa seca de capítulos florais, o teor e o rendimento de óleo essencial e o flavonoide; para as condições testadas recomenda-se utilizar 5 kg m -2 de esterco de ave e lâmina de irrigação equivalente a 150% ETo para a produção de óleo essencial e flavonoide. IntroductionChamomile is a medicinal and aromatic plant of great importance for the cosmetic and phytotherapeutic industry. It is the medicinal plant of greatest economic expression in the South region with cultivated area of 2,000 thousand ha in Paraná (Corrêa Júnior & Scheffer, 2014).Irrigation management consists in the rational use of water in order to meet the requirements of the plants, increasing production and water use efficiency (Shock & Wang, 2011;Pinto et al., 2014;Afshar et al., 2014). The water balance is one way of managing irrigation, considering the processes of absorption, conduction and loss of water. The difference between the water absorbed and lost by the plant is a relevant factor for the metabolic processes of adjustment of the plant (Bilibio et al., 2010).In situations of water deficit, medicinal plants can activate the secondary metaboli...

“…The regression analysis showed that the water volume applied had a strong correlation with LDM, presenting an R² of 0.9980 in the seconddegree polynomial regression (Figure 3B). Meira et al (2013) observed dry mass values between 2.39 and 7.16 g, where the lowest values were obtained in the plants that received the lowest water volumes (50% of the reference evapotranspiration) and the highest values in the plants that received the highest water volumes (175% of the reference evapotranspiration). Through regression analysis, the authors obtained an R² of 0.931 in the linear regression.…”

The water consumption, leaf dry mass (LDM), essential oil yield (Y), essential oil production (Prod), and water productivity as a function of the LDM and the essential oil production of lemon balm were evaluated. The treatments included 25%, 75%, 100%, and 125% crop evapotranspiration (ETc) replacement by irrigation with untreated water (CW) and magnetically treated water (MTW). Through analysis of variance (F-test), means tests (Scott-Knott), and regression analysis, it was observed significant differences among the water replacement level but not between the water treatment. The contribution of magnetically treated water was not clear from the results obtained. The water productivities as a function of leaf dry mass and essential oil production shows the 75% of ETc quite promising for achieving satisfactory leaf production and efficient oil production relative to the amount of water applied.

“…The present climatic conditions in the north, west (Minas Gerais Triangle), northwest, and east were considered suitable for the development and production of urucum. This result is very important, because few of the crops in the north are well adapted to the low water conditions (Meira et al 2013), so the introduction of a new adaptive regional crop is socio-economically important as an optional new income for the farmers in the region (Silva et al 2007). Unaí, Janaúba, Nanuque, Iturama, and Manhuaçu were considered suitable regions for cultivation and Minas Gerais did not contain any marginally suitable regions.…”
