| dc.description.abstract | Increasing the number and quality of pasture needs to be done to meet the
needs of livestock feed. The purpose of this study to determine the potential of
biogas sludge used as organic fertilizer for pasture forage mixture so as to
increase the production of forage. Planting forage research has been conducted
in the District Silangit Installation Siborongborong, North Tapanuli and know the
content of the forage research carried out in the Laboratory of Animal Feed
Ingredients Faculty of Agriculture, University of North Sumatra. The method
research uses split plots design with 2 factors. The first factor is slude biogas (SJ:
Without the use of sludge I control, S2: Use 1 liter of sludge, S3: Use of sludge 2
liters), the second factor is a combination of the type of pasture (Po: King
Grass + Brachiaria humidicola + Brachiaria descumbens, P1:King grass +
Brachiaria humidicola + Arachis vintoi, P2: King grass+ Brachiaria descumbens
+ Arachis vintoi, P3:Brachiaria humidicola + Brachiaria descumbens + Arachis
vintoi, P4:King grass + Brachiaria humidicola + Stylosanthes guaianensis,
P 5:King grass + Brachiaria descumbens + Stylosanthes guaianensis,
P 6:Brachiaria humidicola + Brachiaria descumbens + Stylosanthes
guaianensiss). Parameters measured were nutrient content (crude fiber and crude
protein), the production of fresh, dry matter production, botanical composition
and carrying capacity.
Results showed that the best nutrient content in PJ and P6 treatment that
crude protein of 21:11 and 21:16 +0.49% +0.84% and crude fiber was 30.46%
and 30.94 +0.29 +0.18%. Nutrient content between sludge treatment showed no
difference. The highest production of dry matter in sludge treatment is the S2
1079. 48 + 22. 68 glplot. Botanical composition of pasture mixtures highest King
grass and Brachiaria humidicola. Highest capacities on the fertilization treatment
is 12.88 +0.27 S2 ST
The results of the research the best treatmen_t is the use of biogas sludge
2L fertilization using pig feces on pasture mix nutritious, fresh material
production, dry matter production, botanical composition and accommodating
capacity. | en_US |
