Dairi Regency for Robusta Coffee plant (Coffea robusta Lindl.). Guided by Ir.
Hardy Guchi MP. and Mariani Sembiring SP. MP.
This research purposed to evaluate the suitability of land for cultivation of
robusta coffee in Dairi with altitude is at 400 - 1700 m above sea level . This
research started to do on May 2013 to November 2013. The research conducted
by taking a sample soil based method free of survey grid with detail of survey
level and then analyzed on the laboratory and land evaluation performed by the
matching method is based on the need of land for plants with properties owned by
land on any limiting factors . The parameters observed in the field are soil depth,
soil drainage, slope, the dangers of erosion, the dangers of flood, and the rock
surface and laboratory parameters analyzed include physical properties (texture)
and chemical properties of the soil pH, soil cation exchanges capacity, base
saturation, C-organic, and soil salinity.
The results showed that the actual land suitability classes for sample 1 is
S3tc, sample 2 is S3tc,nr, sample 3 is S3tc, sample 4 is S3tc,nr,eh, sample 5 is
S3tc,nr, sample 6 is S3tc,nr, sample 7 is Nrc, sample 8 is S3tc,nr, sample 9 is
S3tc,rc,nr, sample 10 is S3tc, sample 11 is S3tc,nr, sample 12 is S3tc,oa,rc,nr,
sample 13 is S3tc,nr, sample 14 is S3tc,rc, sample 15 is S3tc,nr,uh, and sample 16
is Nrc. Potential land suitability classes for sample 1 is S3tc, sample 2 is S3tc,
sample 3 is S3tc, sample 4 is S3tc, sample 5 is S3tc, sample 6 is S3tc, sample 7 is
Nrc, sample 8 is S3tc, sample 9 is S3tc,rc, sample 10 is S3tc, sample 11 is S3tc,
sample 12 is S3tc,rc, sample 13 is S3tc, sample 14 is S3tc,rc, sample 15 is S3tc,
and sample 16 is Nrc.88 HalamanSkripsi Sarjan
