A field investigation was conducted at CSIR- Institute of Himalayan Bioresource Technology (Council of Scientific and Industrial Research), Palampur to study the effect of transplanting date on duration of phenophases, aerial biomass partitioning and essential oil productivity in wild marigold (Tagetes minuta). Tagetes crop was transplanted on six dates commencing from April 12 to June 26, 2008 at fortnightly interval. All the phenophases were hastened when the transplanting was delayed. Plant height, leaf number and branches/ plant were significantly higher in the crop which was transplanted in the month of April. Dry matter accumulation in different plant parts of tagetes was significantly higher in April 26 transplanted crop. In accordance with these results, herb yield was significantly higher in the crop which was transplanted on April 26. Delay in transplanting significantly decreased essential oil content. Delay in transplanting also caused variation in composition of the oil in the stem, leaf and flower. Flowers and leaves accumulated maximum essential oil. The proportion of dihydrotagetones (39.1 %) was higher in leaf oil while the presence of cis- ocimene (36.5 %) and ocimenones (41.3 %) in flower oil was recorded.
