Enhancing the growth and yield of Ramie (Boehmeria nivea L.) by ramie biomass waste in liquid form and gibberellic acid

Ramie (Boehmeria nivea L.) is one of the most important sources of natural fibre, a sustainable biomass. The growth and yield of ramie are affected by mineral nutrients. In the present study, we usedfertilizers from waste of ramie biomass in liquid form (liquid organic fertilizer, LOF) and the other treatment is by gibberellic acid (GA3). This study was to obtain the effect of treatments on enhance the growth and yield of ramie. Hence, we measure the character that related to the important parameter for biomass product of ramie. Such plant height, stem diameter, dry plant weight, and ramie fresh stem weight of ramie clone Pujon 13. This research was conducted from January 2016 to March 2016 at Research Field Ciparanje, Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang, West Java with an altitude of about ± 750 m above sea level. The type of Soil in this area is Inceptisolsoil order and thetype of rainfall according to Schmidt and Fergusson Classification is C type. The experiment used Randomized Block Design (RBD) which consisted of eight treatments (GA and LOF) and four replications. The concentration of GA from 0, 50, 100 and 150 ppm and for concentration of LOF is 40 mlL-1. We suggested the treatment of GA 150 ppm with 40 mlL-1 LOF was the best treatment on enhancing plant height and stem fresh weight of ramie clone Pujon 13.
