| Abstract: | A study was conducted to investigate the response of Mentha spicata Linn. emend. Nathh. cv. ‘Arka’ an essential oil bearing plant, to sole and conjoint
application of different level of Fe and Mn with respect to its influence on
herb yield, nutrient uptake and oil quality. For this a pot experiment was
conducted under glasshouse conditions during the year 2005 at Central Institute
of Medicinal and Aromatic Plants (CIMAP) in Lucknow. M. spicata plants were grown through suckers with four graded
levels of iron and manganese, viz. Fe- 0, 5, 10 and 15 mg/kg and Mn 0, 2.5, 5
and 10 mg/kg and a combination of both these elements. From the results
obtained, it is evident that the fresh weight, dry weight, oil yield and
chlorophyll content showed a significant increase with increase in Fe supply;
the optimal level of Fe as revealed by the results was Fe 10 mg/kg supply. Sole
supply of manganese showed the optimal level to be Mn 2.5 mg/kg; beyond which
growth parameters showed a gradual and significant decline. Sole supply of Fe
and Mn 10 mg/kg and 2.5 mg/kg, respectively, showed maximum carvone percentage
in M. spicata oil. |
