Abstract

The development and replanting of smallholder oil palm is rapid and massive; its success from the beginning is determined, among others, by sufficient quantities of seeds with good quality. Nutrient management is the highest priority in nurseries, and along with strengthening the application of sustainability principles in the palm oil industry, alternative sources of nutrients other than inorganic fertilizers are needed. This study aimed to determine the right concentration of Azolla liquid organic fertilizer to increase the growth of oil palm seedlings in pre-nursery. The study was a single factor arranged in a completely randomized design. The studied treatment of POC Azolla concentrations of 100, 85, 75, 65, 55, 45, 35, 25, 15%, plus compost treatment of Azolla solids, NPKMg (15-15-6-4) and urea with 8 repetitions. Required seedlings (9+3) x 8 = 96 polybags. The results showed that applying Azolla POC concentration of 15-35% and solid Azolla compost provided the growth of oil palm seedlings in the pre-nursery, which tended to be better than inorganic fertilizers. POC in this concentration range also results in a better seedling root system, thus potentially increasing the adaptability of oil palm seedlings after being transplanted on permanent land

Abstract

Kelapa sawit merupakan tanaman perkebunan yang membutuhkan curah hujan yang merata sepanjang tahun. Curah hujan diIndonesia memiliki 3 pola yaitu pola monsoonal, equatorial dan lokal. PT. Harapan Hibrida Kalbar Sungai Bila Estate merupakan wilayah kajian penelitian ini memiliki pola curah hujan equatorial. Curah hujan dapat menyimpang dari pola kondisi iklim pada umumnya karena adanya variabilitas iklim El Nino Southern Oscillation dan Indian Ocean Dipole. Hasil koefisien korelasi pearson antara curah hujan musim Juni Juli Agustus dan September Oktober November dengan indeks El Nino Southern Oscillation sebesar -0,78** dan -0,64*. El Nino Southern Oscillation Memiliki hubungan yang kuat dan terbalik dengan curah hujan diwilayah kajian saat musim kemarau dengan nilai signifikan pada selang kepercayaan 0,01 ( Juni, Juli, Agustus) dan 0,05 (September, Oktober, November) Hasil koefisien korelasi pearson antara curah hujan musim Juni Juli Agustus dan September Oktober November dengan indeks Indian Ocean Dipole sebesar -0,4 dan -0,5. Pengaruh El Nino Southern Oscillation lebih kuat dibandingkan dengan Indian Ocean Dipole di wilayah kajian. Fase El Nino (lanina) menyebabkan curah hujan diwilayah kajian menjadi lebih rendah (tinggi) dari kondisi normal, sehingga terjadi kemarau Panjang (Kemarau basah). Produksi kelapa sawit pada jenis tanah Sandy Loam lebih fluktuatif dan lebih rentan saat terjadi kemarau panjang dibandingkan jenis tanah clay. Produksi kelapa sawit lebih dipengaruhi oleh jumlah hari hujan dibandingkan jumlah akumulasi curah hujan dalam setahun.

Abstract

The expansion and replanting of oil palm plantations require the availability of qualified seedlings to anticipate the biotic and abiotic stresses. The use of arbuscular mycorrhizal fungi (AMF) and Trichoderma biofertilizers is an alternative in the management of oil palm nurseries. This study is a factorial experiment arranged in a completely randomized design. There are three levels of AMF doses, namely: 0, 15, and 30 g/seedling; and there are three levels of Trichoderma doses, namely: 0, 10, and 15 g/seedling. There are nine treatment combinations with six replications, 54 pre-nursery oil palm seedlings are needed with seedling growth components and AMF colonization as observed parameters. The results of the study showed that the application of AMF 30 g/seedling and Trichoderma 15 g/seedling resulted in the highest level of mycorrhizal colonization in the roots of PN oil palm seedlings. The application of 30 g of AMF/seedling and 10 g of Trichoderma/seedling resulted in better biomass of PN oil palm seedlings, although not significantly different from the application of 15 g of AMF/seedling and 0 or 10 g of Trichoderma/seedling.

Abstract

Inceptisols are widely distributed in tropical regions, including Indonesia, and are characterized by high rainfall and intensive weathering. These conditions promote severe nutrient leaching, low cation exchange capacity (CEC), and moderately to slightly acidic soil pH, thereby limiting nutrient availability, fertilizer-use efficiency, and crop productivity, particularly in oil palm (Elaeis guineensis) plantations. This study aimed to evaluate the effects of BIO SOLID 17, an organic soil conditioner derived from palm oil mill effluent (POME) sludge, on the chemical and physical properties of Inceptisol through a controlled incubation experiment. A two-month laboratory incubation was conducted using a randomized complete block design with five application rates of BIO SOLID 17 (0, 5, 10, 15, and 20 kg ha⁻¹), each with five replications. Observed parameters included soil pH, cation exchange capacity (CEC), and water-holding capacity (WHC), which were analyzed using standard methods. The results demonstrated that BIO SOLID 17 application significantly improved Inceptisol soil quality in a dose-dependent manner. Soil pH increased from strongly acidic conditions (4.85) in the control to near-neutral levels (6.19) at the highest application rate. Soil CEC also increased significantly from 34.41 to 47.49 cmolc kg⁻¹, indicating enhanced nutrient retention capacity. In addition, soil water-holding capacity increased from 46.82% to 55.81%, reflecting improvements in soil aggregation and moisture retention. Overall, BIO SOLID 17 shows strong potential as a sustainable organic soil amendment for improving the chemical and physical fertility of Inceptisol. The utilization of POME-based materials supports circular economy principles by converting agro-industrial waste into value-added agricultural inputs. Further field-scale studies are recommended to confirm effectiveness and determine optimal application rates under oil palm plantation systems.

Abstract

Spodosols have been widely used for oil palm plantations, specifically in Kalimantan, Indonesia. However, they are sub-optimal for agriculture due to a lack of water and nutrient-holding capacity and a spodic layer that limits plant root development. Therefore, proper agriculture practices are needed for oil palm to enhance its potential yield. This study aims to determine the effect of the mounding technique on the physiological performance and yield of oil palms in spodosol. The study location was well-managed, with eight blocks of oil palm plantations planted in 2008 on spodosols (Typic Haplohumod) in Central Kalimantan. The mounding technique was applied to four blocks of oil palm planted in 2015, while the remaining four were left without mounding. The parameters observed were soil moisture, transpiration, number of bunches, bunch weight, and yield. The results showed that the average moisture in the mounded soil was 4% greater than the control.  Additionally, the average daily transpiration of oil palm with the mounding was up to 2.30 mm day-1 or three times higher than the control.  The implication was that the average yield of oil palm increased from approximately 1.84 to 3.71 tons ha-1 year-1 compared to no-mounding treatments. Furthermore, the average yield was 19-66% higher than the block without the mounding application.

Abstract

The same rainfall can cause different degrees of water stress depending on soil type, so the production response shown by plants can be different. This study is essential for growers, especially in predicting oil palm production based on water deficit for each soil type. The study was conducted on oil palm plantations in Central Kalimantan, Indonesia, with four soil types in 1,446.15 ha (40 blocks). The source of data collected from oil palm plantations included bunch number, average bunch weight, rainfall, and soil physical and chemical properties for the last 15 years (2007 - 2021). This experimental study used a two-stage cluster sampling method. The results showed that the best productivity, bunch number, and average bunch weight were found on Ultisols. The four soil types tested showed the same annual production distribution dynamic, but the response rate from each soil type showed differences. Entisols and Spodosols were more prone to drought stress due to water deficit than Ultisols and Histosols because of the differences in soil texture. Water deficit causes a decrease in oil palm productivity by 5 - 22% in the first year (Ultisols 12 - 22%; Entisols 12 - 22%; Spodosols 7 - 19%;  Histosols 5 - 15%) and 1 - 8% in the second year (Ultisols 3 - 7%; Entisols 2 - 4%; Spodosols 5 - 8%; Histosols 1 - 5%) compared to previous years production. A decrease in oil palm productivity occurs at 3 - 5 months (bunch failure phase), 1 year (abortion sensitive phase), and 2 - 2.5 years (sex differentiation phase) after a water deficit appears.

Abstract

Management of sandy soil in oil palm plantations requires location-specific technology that prioritizes sustainability principles. Palm oil mill Effluent (POME) has the potential to be a substitute for nutrients for oil palm plantations. This research aims to reveal the role of POME in improving soil and tissue nutrient status and increasing oil palm production on sandy soil. The research was conducted on eleven plantation blocks using POME and six blocks without by-products (30 ha block-1, sandy soil) of 12-13 years palm. Observations were carried out for 3 years, including harvest tonnage, number and weight of fresh fruit bunches (FFB) of palm oil, soil, and tissue nutrient content (N, P, K, Mg, Ca, Cu, and B), CEC, and soil organic carbon. The research results show that POME flatbed system application can increase the nutrient content, pH, CEC, and soil organic carbon in the low to medium range. This application can also increase the tissue nutrient content to the optimal range. Production, quantity, and weight of oil palm FFB on sandy soil applied by POME were increased compared to those without by-product application. This application can also reduce monthly fluctuations in palm oil production on sandy soil.
