Abstract: To find out the influence of date of planting, land configuration and planting geometries on the fresh herbage yield and essential oil yield of patchouli under sub-mountaineous region of Punjab, three planting dates of patchouli plot viz. September 20, October 5, October 20, two land configurations (Bed and Flat planting) in sub-plots and three planting geometries viz. 90×30cm, 90×45cm, 90×60cm were evaluated during 2013-14 and 2014-15. The maximum plant spread was observed with October 20, which was statistically at par with October 5. Patchouli planted on beds attained more plant spread which was significantly higher than that of flat planted plots. The maximum values of plant spread were produced by planting geometries of 90×60cm, which was statistically at par with 90×45cm. The highest herbage yield and essential oil yield were recorded in October 20 which was statistically at par with October 5 at both harvests during both the years of study. Significantly higher fresh herbage yield and essential oil yield in both the harvest were recorded in bed planting than in flat planting among both the harvests of patchouli. Among planting geometries, the highest fresh herbage yield and essential oil yield was observed 90 cm×30cm in both the harvest and proved significantly superior to 90×45cm and 90×60cm. The date of planting, land configuration and planting geometries resulted in statistically similar values of oil content of patchouli at both harvests during both the years of study.
