| Summary: | The aims of this study were to determine the growth and the
productivity (production, chemical composition and in vitro digestibility) of
Sorghum bicolor (L.) Moench planted in Merapi eruption soil and were added
with various levels of organic fertilizier. Polybag was filled using soil from
Karangmalang (as external control) and Merapi eruption soil added with 0, 5
and 10 ton/ha organic fertilizer as planting media. SP36 100 kg/ha was added
once during preparation of planting media, urea 200kg/ha was added two
times during the cultivation, and planting space was 50x30 cm. Observations
of plant growth and number of leaf were observed every week during 13
week. Harvest at milk stage, cutted, weighed, sample in oven 55oC and gried.
Before analyzed proximate and in vitro digestibility Tilley and Terry two
stages included dry matter digestibility and organic matter were done. Data
was analyzed using analyzed of various for Completely Randomized Design
(CRD) and the differend betweent means was using Least Significant
Difference (LSD) test. The result showed that plant height, dry matter
production, in vitro digestibility dry matter affected (P<0,05) by addict of
organic fertilizer in Merapi eruption soil. Plant height increase for 87,55 cm to
118,12 - 126,00 cm, dry matter production for 2,82 ton/ha to 5,20 - 5,68
ton/ha, and in vitro digestibility dry matter for 65,39% to 66,37 - 69,20%.
Based in the study included the addition of organic fertilizers 5 and 10 ton/ha
on Merapi eruption soil increased the growth and the productivity sorghum,
however not equal than sorghum planted in soil from Karangmalang. |
