“…Comparatively, the mean content of 1.51 mL 100 g -1 dry matter found in the present study, which was obtained with plants grown with 28 t ha -1 of biosolid, could be considered high and indicative of stress or adaptation to sludge. The results obtained in several works indicated discrepancy due to experimental conditions and harvest periods, variables in which plants were submitted, which interfered with mint essential oil content and composition (Reitsma et al, 1961;Marotti et al, 1997). In the conditions of the present work, a high percentage of shoot dry matter was observed in plants grown with the highest biosolids level although increase in essential oil content was not observed.…”

“…Valmorbida (2002), in an investigation where mint was grown in a complete nutritive solution under the same climatic conditions, verified a mean oil yield of 1.27 mL.100 g -1 DM. In the present work, the mean yields of 1.51 and 1.27 mL.100 g -1 DM obtained with plants grown at Biosolid levels (t.ha -1 ) Essential oil yield (ml.100 g -1 DM) Marotti et al (1993) reported that menthyl acetate content increased from 1.6 to 17.0% up to the end of the development cycle of M. piperita L. plants. However, the same authors explained that determining harvest time accurately is important for best yield and oil quality.…”

“…(2) to the relatively low N application rate (80 kgÁha -1 ); and (3) the variability within the experiment, which might have masked the response to N. Further research with higher N application rates may be needed to establish optimal N and other fertilizer requirements of peppermint in the southeastern United States. Timing of the harvest is important with respect to oil yield and composition (Clark and Menary, 2006;Marcum and Hanson, 2006;Marotti et al, 1993;Rohloff et al, 2005;Zheljazkov, 1998) and with respect to the overall economics (Mint Industry Research Council, 2009). Generally, our results confirm previous reports regarding the effect of location and harvest stage on peppermint biomass yields, oil content, and composition (Clark and Menary, 2006;Marcum and Hanson, 2006;Rohloff et al, 2005;Zheljazkov, 1998).…”

In the northwestern United States, and in other countries, peppermint is usually harvested at the flowering stage Menary, 1979a, 2006;Marcum and Hanson, 2006;Marotti et al, 1993;Rohloff et al, 2005;Zheljazkov, 1998) when the (-)-menthol concentration of the oil is the highest and the concentrations of (-)-menthone and (+)-menthofuran are decreasing. We have observed a similar trend in this study in Mississippi.…”
