Abstract

AbstractEffort to increase the production of oil palm can beconducted through application of plant growth regulator(PGR). Orgamin biostimulan is a natural PGR formulathat has been tested to improve the vegetative growths ofcorn and oil palm in the glass house. Assessment ofOrgamin and Orgamin plus (Orgamin + micro nutrient)applications at commercial scale was carried out inMarjandi oil palm plantation of PTPN IV usingrandomized block design with three treatments, i.e. K =100% recommended dose of inorganic fertilizer(control), O= Orgamin (1.5 kg/tree) + 50% dose ofinorganic fertilizer, OP = Orgamin plus (1.5 kg/tree)without inorganic fertilizer. The parameters ofobservation at 2.5 months after the treatments were soiland leaf nutrient contents (N, P, K, Mg), percentage offemale flower, mesocarp oil content, and harvested freshfruit bunches (FFB). The observation showed that therewas an increased in oil yield, weight of FFB and leafnutrient content, while the percentage of female flowerand nutrient content of soil were not significantlydifferent compared to the control.AbstrakUpaya untuk meningkatkan produksi kelapa sawitdapat dilakukan antara lain melalui pemberian zatpengatur tumbuh (ZPT). Biostimulan Orgamin merupa-kan formula ZPT alami yang telah diuji di rumah kacapada tanaman jagung dan bibit kelapa sawit. Uji cobaaplikasi Orgamin dan Orgamin plus (Orgamin yangdiperkaya hara mikro) pada skala lapang dilakukan dikebun kelapa sawit Marjandi PTPN IV denganmenggunakan Rancangan Acak Kelompok (RAK) untukmenguji tiga perlakuan, yaitu 1) K (kontrol) = 100%dosis anjuran pupuk kimia (APK = kontrol), 2) O = 50%dosis APK + Orgamin (1,5 kg/pohon), 3) OP = Orgaminplus (1,5 kg/pohon) tanpa pupuk kimia. Peubah yangdiamati pada 2,5 bulan setelah perlakuan adalah kan-dungan hara tanah dan daun (N, P, K, Mg), persentasebunga betina, rendemen minyak mesokarp, dan produksitandan buah segar (TBS). Hasil yang diperoleh menunjukkan terdapat peningkatan rendemen minyak, bobotTBS dan kandungan hara daun, sedangkan persentasebunga betina dan kandungan hara tanah tidak menunjuk-kan perbedaan yang nyata antara perlakuan dan kontrol.

Abstract

AbstractThe extension of oil palm area has been expanded tomarginal land such as the highland regions. However, theproductivity of the oil palm became the main demand for theplanters. Increasing of oil palm productivity can be done byapplication of growth regulators. Growth regulators aresmall molecules in a relatively very small amount that affectthe growth and development of plant. This study wasconducted to asses the efectiveness of plant growth regu-lators (Orgamin and Orgamin plus) in improving fertilizerefficiency and productivity of mature oil palm (TM 7). Theexperiments were conducted at Marjandi oil palm plantationat an altitude of 700 m above sea level in a total area of 16 ha. Six treatments tested were 1). 100% inorganicfertilizer (control), 2). 50% inorganic fertilizer + Orgamin(50K+O), 3). 75% inorganic fertilizer + Orgamin (75K+O),4). 50% inorganic fertilizer + Orgamin plus (50K+OP), 5).75% inorganic fertilizer + Orgamin plus (75K+OP), and 6).100% inorganic fertilizer + Orgamin plus (100K+OP)arranged in a randomized block design (RBD) with threereplications. Orgamin (O) and Orgamin plus (OP) wereapplied in the hole around the oil palm along with inorganicfertilizers. The results showed that application of O and OPimproved the efficiency of inorganic fertilizers by 50% basedon vegetative variables and increased the concentration ofN, P, and K of leaf and soil compared to those of 100%inorganic fertilizer. In addition to the height and leaf numberof plant parameters, the leaf of the plant treated with O andOP showed more greenish compared to those of control.There is an indication that the O application increased thepercentage of female flowers. In addition the application ofOrgamin also produced the highest oil content in oil palmfruit particularly in the treatment of 75% of inorganicfertilizer + orgamin harvested in October compared to thosein March. Moreover, application of OP increased both thetotal weight and weight per bunch of FFB.AbstrakPengembangan kelapa sawit mengharuskan pengguna-an lahan suboptimal seperti daerah dataran tinggi.

Baik data bobot per tandanmaupun bobot TBS menunjukkan bahwa pemberian OPdapat meningkatkan kedua peubah tersebut.
