Pola Pertumbuhan Rumput Signal (Brachiaria humidicola (Rendle) Schweick) pada Padang Penggembalaan dengan Aplikasi Sumber Nutrien Berbeda
Abstract: An investigation on
growth behavior parameters and its dynamic pattern of signal grass (Brachiaria
humidicola) grown under influence of inorganic and organic nutrient supply was
conducted during period of wet and early dry seasons in 2004. Five sets of
treatments consisted of control (P0), mulch originated from pasture weed
biomass (Chromolaena odorata) (PC), animal dung (PF), combination of mulch and
dung (PC+F) and inorganic fertilizer (PA) were applied to one year existing
signalgrass plots. Block randomized design with 4 replications was used in this
experiment. The results showed that application of PA produced the highest
length of stolons, node and tiller numbers. There was an improvement of growth
by application of PC, PF and PC+F, but at lower level than those of PA.
Application of PA caused short growth period (6-8 weeks) to reach maximum
length of stolon, node and tiller numbers, but less persistent (10-12 weeks) if
the grass had not been defoliated. On the other hand, application of organic
nutrient led to slow growing grass, but it showed more persistent. The
application of organic nutrient supply (PC, PF and PC+F) resulted the best
growth of signal grass in comparison with control and more persistent than that
of inorganic fertilizer (PA).
