The effect of bio-slurry fertilization on growth, dry matter yield and quality of hybrid sudangrass and sorghum (Sorghum bicolor) Samurai-2 variety
Rohmiyatul Islamiyati, Budiman Nohong
Abstract: The objectives of this research were to evaluate the growth, production and quality characteristics of the hybrid sudangrass and sorghum Samurai-2 variety treated by different doses of liquid bio-slurry. This experiment was conducted using a complete randomized design with 2 factors in which the fi rst factor was the type of plants (hybrid sudangrass and sorghum Samurai-2 variety) and the second factor included bio-slurry liquid fertilizer: P0 = no fertilizer (control), P1 = 5.750 kg bioslurry/ ha and P2 = 11.500 kg bio-slurry/ha. The data were analyzed using the variance analysis and DMRT test. There was no
interaction between the types of plants and fertilization. Plant height, long of internode, number of leaves, dry matter production, crude protein content and dry matter digestibility of hybrid sudangrass (P < 0.05) were signifi cantly higher and the NDF, ADF and ADL content were signifi cantly lower (P < 0.05) than those of the sorghum Samurai-2 variety. On the other hand, the weights of panicles and seeds of the sorghum Samurai-2 variety (P < 0.05) were higher than those of hybrid sudangrass. The fertilization with bio-slurry signifi cantly increased (P < 0.05) the weights of panicles, seeds and crude protein content, but also signifi cantly decreased (P < 0.05) the NDF content. It can be concluded that the hybrid sudangrass has the potential to be developed as a forage-producing crop because its production and quality are higher, while the sorghum Samurai-2 variety can be developed as a seed producer or forage.
