Productivity of Brachiaria decumbens in a mixed-culture with Pueraria phaseloides in different manure and dolomite administration level in the suboptimal land

Iwan Herdiawan


Productivity improvement of forage in suboptimal land can be done in various ways, such as through manure and ameliorant treatment. Manure and dolomite is needed by the soil on suboptimal land, because the combination of the two can supply nutrients and improve the soil biophysical. The research materials used were B. decumbens, Pueraria phaseloides, manure, and dolomite. The study used Randomized Block Design (RBD) in 3x3 factorial. The dose of manure was the first factor and dose of super dolomite was the second factor, each treatment received 3 times replications. Variables measured were biomass production, dry matterial production, carrying capacity, and nutrient content of forage. The results showed that the highest (P<0.05) biomass production produced by the 10 t/ha manure and 2 ton/ha dolomite treatment by 1,638.94 g/m2 compared to other treatments, and the lowest was achieved in the control by 543.75 g/m2. Carrying capacity of B. decumbens and P. phaseloides on 10 ton/ha manure was the highest (P<0.05) by 0.08 AU compared to others treatment. Super dolomite administration by 1 ton/ha significantly (P<0.05) produced highest carrying capacity by amount of 0.83 AU. Manure and dolomite administration significantly (P<0.05) improved the nutritional content of B. decumbens and P. phaseloides.
