PERTUMBUHAN BIBIT KARET (Hevea brasiliensis) OKULASI PADA MEDIA CAMPURAN SUBSOIL DENGAN PUPUK ORGANIK
Abstract: Rubber tree (Hevea
brasiliensis) is one of the strategic agricultural commodities for the economy
in Indonesia, both in increasing revenue planters, providing jobs for
residents, preserve the environment and also as a source of foreign exchange.
The use of the subsoil is expected to produce good growth of rubber seedlings
which when mixed application of organic fertilizers. Through the use of organic
fertilizers is expected to increase the holding power of water, nutrients and
repair donated soil aggregates. This study experimentally using a completely
randomized design (CRD) consisting of 5 treatments and 5 replicates so entirely
as many as 25 experimental units. Each unit consists of 2 plants as well as a
sample, so that the overall number of 50 plants. Data obtained from the results
of the study were statistically analyzed using analysis of variance (ANOVA)
followed by test Honestly Significant Difference (HSD) at the 5% level.
Parameters measured were seedling height increment (cm), stem diameter
increment (cm), in the number of leaves (strands), root length (cm), root
volume (ml), seedling dry weight (g) and the ratio of the root crown. The
mixture of subsoil with organic fertilizer oil palm empty fruit bunches of the
best shows on rubber seedlings (Hevea brasiliensis).
