Liquid organic fertilizer provides nutrients, increases good microorganisms and improves the physical properties of the soil, especially when used in oil palm nurseries. This research was conducted with the aim of determining the effect of providing liquid organic fertilizer and NPK on the growth of oil palm seedlings in the pre-nursery. This research uses a factorial experimental method arranged in a Completely Randomized Design (CRD) consisting of two factors. The first factor is liquid organic fertilizer which consists of 4 levels, namely Control/no fertilizer, 3 ml, 5 ml 8 ml. The second factor is NPK which consists of 4 levels, namely N1: Control/no fertilizer, N2: 1 g/plant, N3: 2 g/plant, N4: 3 g/plant. Each treatment was repeated 5 times. The data obtained were analyzed using Analysis of Variance (anova) with a level of 5%. Data that were significantly different were further tested with DMRT at a level of 5%. The results showed that there was a real interaction between liquid organic fertilizer and NPK on stem diameter. The best growth of oil palm seedlings at a dose of 1 g NPK fertilizer with 8 ml liquid organic fertilizer showed a value of 7.06 mm, a 2 g dose of NPK with a control liquid organic fertilizer showed a value of 7.02 mm, a 2 g dose of NPK and a dose of liquid organic fertilizer 3 ml shows a value of 7.00 mm. Real interaction between liquid organic fertilizer and NPK on crown fresh weight diameter. NPK at a dose of 1 g and POC at a dose of 3 ml showed a value of 6.46 g. Providing liquid organic fertilizer did not have a real effect on oil palm seedlings, while NPK at a dose of 1 g/plant had an effect on oil palm seedlings.

Legume Cover Crop (LCC) used in Palm plantations has not yet produced for weed control because there are still large open lands. To prepare LCC seedling of the Mucuna bracteata species, a medium is required that provides good root growth, inter alia, with the addition of organic material derived from various animal debris. This research aims to find out the influence as well as the interaction of type and comparison of the volume of cage fertilizer on the growth of LCC Mucuna bracteata on the latosol soil that has been carried out at the KP2 INSTIPER, Maguwoharjo, Yogyakarta, Yogyakarta and at the Central Laboratory, Instiper on April 20, 2021 to June 30, 2021. This research uses a complete random design (RAL) or Completely Randomized Design (CRD) method that consists of two factors. The first factor is a type of cage fertilizer that consists of three levels, namely cage, chicken and goat fertilizers. The second factor is the comparison of the volume of the soil of the latosol with the cage of 3 levels of 1:1, 2:1, and 1:2 with 10 repetitions. The results of the study were analysed with the analysis of variance prints at the significance level of 5%. The effective treatment was further tested with the Duncan Multiple Range Test (DMRT) using the significance level of 5%. Results of the analysis showed that the treatment of cage fertilizer and the comparison of the soil volume of latosol with cage fertilizer did not have a real interaction and both treatments gave the same effect on the growth parameters of plants, including its length, leaf number, shoots number, top fresh weight, top dry weight, root length, fresh root weight and dry roots of Mucuna brate plant. Cage fertilizer and volume comparison gives the same bet on all the growth parameters of Mucuna bracteata.

This research aims to assess the impact of rice husk charcoal and fruit eco-enzyme concentrations on the growth of oil palm seedlings during the pre-nursery stage. Conducted in Wedomartani, Ngemplak, Sleman, Yogyakarta, from May to August 2024, the study employed a factorial experiment using a Completely Randomized Design (CRD) with two factors. The first variable was rice husk charcoal with four treatment levels: no charcoal (control), ratio of husk charcoal and topsoil 1:4, ratio of husk charcoal and topsoil 1:2, and ratio of husk charcoal and topsoil 2:1. The second variable was eco-enzyme concentration at three levels: 0%, 10%, and 20%. These combinations resulted in 12 different treatments, each replicated three times, with two seedlings per replication, requiring a total of 72 polybags (2 seedlings x 3 replications x 12 treatments). Data were analyzed using ANOVA at a 5% significance level, and if significant differences were found, further testing was conducted using DMRT at the same significance level. The findings revealed no significant interaction between the use of rice husk charcoal and eco-enzyme concentrations on the growth of oil palm seedlings. The various ratios of rice husk charcoal (control, 1:4, 1:2, 2:1) had similar effects on seedling growth, and the different eco-enzyme concentrations (0%, 10%, 20%) also showed uniformly positive effects on seedling development.

Introduction: Oil palm nurseries are crucial to oil palm farming success. Thus, precise management measures from the start, such as giving nutrients and using optimal planting material, are essential. Vermicompost and guano were tested as organic fertilizers in oil palm fields to replace chemical fertilizers. This study aims to evaluate the effect of guano and vermicompost as organic fertilizers on the growth of oil palm seedlings during the pre-nursery stage. Methods: Besides the control group, the experimental treatments included 10% vermicompost, 20% vermicompost, 10% guano, and 20% guano, each replicated five times in a completely randomized design. Results: The introduction of 10% guano resulted in a significant enhancement across key growth metrics Addition of 10% guano had 20.0% more leaves, 22.5% more stem diameter, and 62.1% more shoot dry weight than the control group. This study shows that guano, which includes 19% P2O5, can boost oil palm seedling growth. The inceptisols was already rich in nutrients, thus vermicompost had no effect on it throughout the three-month testing. Since the soil conditions were good, vermicompost did not change them during the three-month trial. The correlation matrix showed a strong and constant link between seedling shoot and root fresh and dry weights. The relationship between organic fertilizers and oil palm nursery growth highlights the importance of a well-rounded plant development profile. This highlights the complex relationship between organic fertilizers and oil palm growth. Conclusion: Guano at 10% has been shown to improve oil palm seedling growth in the nursery phase, outperforming vermicompost.

In oil palm growth, planting density has a sustainable impact on its productivity. To enhance the long-term growth and production yield of oil palm, it is crucial to consider the establishment of appropriate planting densities during the initial planting phase. This research explores the relationship between planting density and productivity, highlighting the importance of determining optimal plant densities for optimal yields. The study was conducted at the Muara Tawang Estate (MTNE) in Kapuas Hulu Regency, West Kalimantan Province. Two blocks of oil palm land with three different planting densities (130, 136, and 143 plants per hectare) were observed to understand the relationship between planting density and agronomic characteristics. Measurements were taken on plant height, frond length, petiole width, number of male and female flowers, and sex ratio. The analysis unveiled consistent trends in oil palm production, which varied based on planting density. Planting densities of 130 and 136 showed superior production trends compared to 143, with 136 demonstrating production increases ranging from 19.8% to 29.8% relative to density 143, alongside enhancements in plant height and frond length by 4.6% and 5.4%, respectively. Additionally, petiole thickness and width were notably lower in density 143, experiencing reductions of 8.0% and 11.0%, respectively, compared to density 136, while the sex ratio exhibited a similar pattern, declining by 34.0% in density 143 compared to 136. This highlights the importance of determining appropriate planting densities to enhance oil palm productivity.

Efforts to increase rice production are being made thru plant breeding activities, including testing or evaluating the agronomic characteristics of promising lines. The purpose of this study is to evaluate the agronomic characteristics of several promising rice lines, namely lines GKYGK 1, GKYGK 2, GKYGK 3, and GKYGK 4, compared to the Gilirang and Segreng Handayani varieties. The research was conducted from November 2022 to March 2023 in Mojosari Village, Playen District, Gunungkidul Regency, Yogyakarta. The tested rice lines and their control varieties were planted in plots measuring 500 m2 each, using the legowo planting system with a spacing of 2:1 or (25 X 12.5 X 50) cm. From each line, 4 tillers were sampled to observe several agronomic characteristics including: plant height, number of productive tillers, panicle length, flag leaf length, flag leaf width, grain length, grain width, number of filled grains, number of empty grains, grain weight per tiller, and weight of 1,000 grains. In addition, yield from the harvested area was also observed. The data obtained were then analyzed using Analysis of Variance (ANOVA). If there were significant differences, the testing was continued with Duncan's New Multiple Range Test (DMRT) at the 5% level. The research results showed that the GKYGK 3 line had high yield potential in several characteristics, such as having the shortest plant height (117.31 cm), the highest 1,000-grain weight of filled grains (29.43 g), and the highest yield per square meter (9.688 kg). The GKYGK 1 line had high yield potential, such as having the highest number of productive tillers (18.56 stems), the longest panicle length (28.47 cm), and the highest grain weight per clump (60.68 g). The GKYGK 2 line had the highest percentage of filled grains (79.33%) and the longest grain length (10.53 mm).
