Abstract

Kenaf (Hibiscus cannabinus L.) is a short-day fiber plant belonging to the Malvaceae family. At present, kenaf is an alternative source of fiber, not only used as a raw material for burlap sacks but can be processed into more prospective industrial raw materials and high economic value. At the national level, the development of natural fibers faces technical and non-technical problems that affect low productivity at the farmer level and reduced quality of results. To overcome technical problems, technological innovation is needed starting from assembling superior varieties, improving cultivation techniques, to providing quality seed sources. The aim of the study was to determine the growth of Kenaf (Hibiscus cannabis (L.) with differences in plant spacing and shoot pruning. The study was conducted at Tanjung Anom Seed Agency Medan in August 2015-October 2015, using factorial randomized block design with two factors, Planting Distance (20cm x 20cm, 40cm x 20cm, 60cm x 20cm, 80cm x 20cm) and Pruning (pruning and no pruning) The variables observed were plant height, stem diameter, number of leaves, canopy fresh weight, canopy dry weight, root fresh weight, weight dry roots, and flowering age. The results showed that the treatment of plant spacing increased plant height, number of leaves, and age of flowering. Pruning treatment increases the fresh weight of the root.
