Pemanfaatan KomposKulit Durian untuk Mengurangi Dosis Pupuk N Anorganik pada Produksi Tanaman Sawi Hijau (Brassica junceae)
Abstrak: The high public demand
for organic products are not comparable with the level of production. One of alternative
producing agricultural healthy products is using agricultural waste as organic fertilizer
for crop production. Durian shell can be used as an alternative material to
make organic fertilizer. The study said that the durian shell can be used into
useful organic fertilizer for plants and improving soil chemical properties.
Based on this potential, research on the use of organic fertilizer from shell
of durian need to performed. The results indicate that the solid organic
fertilizer durian shell contains 14.6% C- organic, 1.69% N, 0.16% P2O5, and
1:20% K2O. The research aims to determine the effect of organic fertilizer from
shell of durian and test their effectiveness in reducing the dose of inorganic
N fertilizer on growth and yield ofgreen cabbage (Brassica junceae). This
research was conductedwith randomized complete block design at the Experimental
Garden Trilogy University, Jakarta. Research in the fieldinclude the dosage of
organic fertilizer (0, 10, and 20 t / ha) and inorganic N fertilizer (0%, 50%,
75% and 100% of the dose recommendation of 250 kg / ha). The results showed no differences
plant growth in all treatments. Fresh wet of shoot in the treatment of 20 tons
of organic fertilizer + 50% inorganic fertilizer dose did not differ
significantly by treatment with 20 tons of inorganic fertilizer + 100%
inorganic fertilizers. This result conclused the application of organic
fertilizer durian shell is able to reduce the dosage of inorganic fertilizer up
to 50%.
