PLANT RESPONSE OF CITRONELLA GRASS (ANDROPOGON NARDUS L.) TO SEVERAL MANURE APPLICATION AND PLANTING MEDIUM COMPOSITION

Manure has many advantages in improving soil texture and structure. The composition of plant media is ratio between soil weight and manure in planting medium. The research aimed to study the interaction manure and planting medium composition to growth and yield of citronella grass. The research was conducted in shade net house of Faculty of Agriculture, Andalas University, Padang, West Sumatera, Indonesia from August 2018 to January 2019. Completely randomized design was used (CDR) that consisted of 2 factors was used in the reserach. The first factor was type of manure (chicken, goat and cattle) and second factor was planting medium composition (ratio of soil weight and manure, 1:1, 1:2 and 1:3). The treatments were replied 3 times and for each experimetnal unit was consisted of 5 plants. The data was analysed by Duncan?s New Multiple Range Test (DNMRT) in 5 %.The result showed that the ratio 1:2 affected dry weight of root. The beast manure application for growth and yield of citronella grass was 2.5 kg/polybag. The best composition of planting medium to cintronella grass was 1:3 for dry weight of root.
