A field experiment on the effect of time of harvesting on yield and quality of Melissa officinalis L. was conducted under the agroclimatic conditions of Doon valley, Uttarakhand in order to assess the performance of four harvesting times (H 1 -120 days, H 2 -140 days, H 3 -160 days and H 4 -180 days after planting). The fresh and dry herbage and oil yield of the aerial parts showed greater response in H 3 i.e. harvesting at 160 days after planting, followed by H 2 harvesting time. The quality of essential oil was evaluated using GC and GC-MS analysis. Geranial (24.53 %) and neral (18.80 %) were the major constituents found in the essential oil followed by trans-caryophyllene (7.70 %).
