Effect of Different Cutting Lengths and Cutting Diameters on Growth and Survival of Patchouli Plants in Nursery

摘要

Patchouli (Pogostemon cablin) is normally propagated vegetative through stem cuttings. Number of factors such as climate, type of cuttings, rooting media, etc. governs the growth and survival of the saplings. Striking effects of different cutting lengths and cutting diameters on growth and survival were observed under Mist Chamber and Agronet shade conditions. The present study was conducted to come out with recommendations regarding appropriate ranges of cutting lengths and cutting diameters for optimum growth and survival of Patchouli in nursery stage. Through the efficient statistical computer algorithm RCDA by varying the different diameters and lengths, results are computed, tested and verified with the maximum survival and growth. The RCDA algorithm helped in processing of datasets into performance groups to better understand the effects of different diameters, lengths of cuttings on survival and growth of patchouli plant.
