dc.description.abstractBlack Pepper (Piper nigrwn L.) is a spice belongs to family Piperaceae and known as the "King" of spices. Propagationthrough stem cuttings is the common practice.Before field planting, stem cuttings should be kept about 1.5 months inside the propagators and another two months under hardening process at the nursery stage. There is a need to identify the proper height of propagator which gives the highest growth and survival rate. Objective of the study was to increase the growth rate of pepper cuttings to produce field-ready plants within a short period of time by changing the propagator height. The experiment was conducted at the Central Research Station, Matale, Sri Lanka, during August to November 2017 and six different propagator heights (30, 40, 50, 60, 70, and 80 cm) were used as the treatments with 3 replications.Growth parameters such as number of leaves,shoot length, root length, number of roots and root volume and survival percentage were analyzed using ANOVA technique. Propagator with 50 cm height produced plants with significantly highest performance with respective to the above growthparameters except number of leaves compared to 60 cm propagator (current practice).Survival percentagesin 50 cm and 60 cm propagators are 99.3% and 98.6% and root volumes were 0.85 cm3and 0.73 cm3,respectively. Therefore, propagator with 50 cm height can be recommended to propagate pepper cuttings within shorter period of time in place of 60 cm propagator.en_US
