Abstract

This research aimed to determine the effectiveness of several types of liquid organic fertilizer (LOF) derived from plant waste and the dose of P fertilizer on the growth and yield of upland rice on degraded acid soil. The treatments consisted of two factors. The first factor (A) was several types of LOF consisting of A1 (control), A2 (LOF containing isolates of P-solubilizing bacteria), A3 (LOF-banana waste), and A4 (A2+A3). The second factor (B) was fertilizer doses consisting of B1 (50% of the recommended dose of P fertilizer), B2 (75% of the recommended dose of P fertilizer), and B3 (100% of the recommended dose of P fertilizer). The treatment combinations were arranged in a factorial randomized block design with three replications. The research results showed that applying either LOF-banana waste or the mixture of LOF-banana waste and LOF-containing isolates of P-solubilizing bacteria improved plant height, the number of tillers, and N and P uptake by the plant. The rice grain yields among the treatments were not significantly different, but the highest rice grain yield (139.8 g/pot) was obtained at the treatment of the mixture of LOF-P isolate + LOF-banana waste (A2+A3 treatments). The 75% of the recommended dose of P fertilizer was not significantly different from 100% P fertilizer with LOF on growth and yield upland rice and nutrient uptake by the plant.

Abstract

Ultisol is generally characterized by a high clay content in the argillic horizon, easy compaction, slow permeability, and unstable aggregates, resulting in low total porosity. Organic soil amendments such as compost and biochar can be used to improve soil organic matter, aggregate stability, and other physical properties of Ultisol. A field experiment was conducted using a randomized block design to assess the potential effects of Leucaena compost (LC) and coconut shell biochar (CB) on the physical properties of Ultisol and maize yield. The treatments included combinations of compost (0, 5, and 10 t/ha), biochar (0, 5, and 10 t/ha), and inorganic fertilizer (50% and 100% of the recommended dose). The results showed that the application of Leucaena compost and coconut shell biochar improved the physical properties of the soil. Compost and/or biochar applications at 10 t/ha enhanced soil organic matter, total porosity, aggregate formation, aggregate stability, pore size distribution, and reduced soil bulk density, improving maize growth and yield.

Abstract

Characteristics of the most prominent former coal mining land are severe damaged land, causing decreased soil productivity, erosion and sedimentation, soil movement and resulting in land slides, and soil compaction so that it is difficult to process. Efforts to improve the physical properties of coal mining reclamation soils, namely by adding biochar and compost. Biochar and compost can improve the physical properties of the soil by increasing the content of organic matter, total pore space, water content and reducing the weight of soil volume. This study uses a complete random design with 6 treatments and 4 replications. The treatment used in this study is B0 without treatment (control); B1 15 tons/ha biochar oil palm shells; B2 10 tons/ha biochar oil palm shells and 5 tons/ha of city waste compost; B3 7.5 tons/ha biochar oil palm shells and 7.5 tons/ha of city waste compost; B4 5 tons/ha Biochar palm oil shell and 10 tons/ha of city waste compost; B5 15 tons/ha of city waste compost. The observed variables are the content of organic matter, the weight of soil volume, total pore space, soil water content in several PF values, plant height, plant yields and the number of plant pods. The results obtained that the treatment combination of 7.5 tons/ha of biochar oil palm shells 7.5 tons/ha of city waste compost is the best composition to improve the groundwater content of coal mining reclamation. Furthermore, the provision of 15 tons/ha of city waste compost has effectively improved soybean yield. Keywords : biochar, compost, some physical properties, coal, soybeans

Abstract

Ultisol has a texture with a high clay content and a medium to high bulk density so it is susceptible to increasing soil compaction. High soil compaction indicates physical soil problems and inhibits plant growth. The application of soil amendments such as biochar and mycorrhiza can help be help improve soil compaction and support corn growth. This study aimed to examine the potential of biochar from palm fronds and mycorrhiza in improving Ultisol compaction and increasing corn yield. The research was conducted by using a randomized factorial design with 2 factors. The first factor was, oil palm frond biochar with 3 levels, no biochar (B0), biochar 5 tons.ha-1 (B5), and biochar 10 tons.ha-1 (B10). The second factor was mycorrhiza with 3 doses, without mycorrhiza (M0), mycorrhiza 10 grams (M10), and mycorrhiza 20 grams (M20). The results showed that the combination of oil palm frond biochar and mycorrhiza did not show an interaction in improving soil density, but had a significant effect on organic matter, plant height, and yield of maize plants. The application of biochar and mycorrhiza alone was able to improve the bulk density, soil porosity, penetration resistance and soil moisture content. The combination of 10 tons.ha-1 biochar and 20 grams mycorrhiza increased soil organic matter, plant height, and corn yield 66.74%, 24.77%, and 30.26%, repectively compared to the control. Thus, the combined application of oil palm frond biochar at 10 tons.ha-1 and mycorrhiza at 20 grams has the potential to improve soil organic matter content and increase corn yield.

Abstract

Oil palm cultivation is increasingly carried out on suboptimal land, such as Ultisols. Application of ameliorant such as biochar and compost may be chosen as an alternative to solve the problem occurred on this sub optimal soil. This study aims to determine the optimal dosage of a mixture of oil palm empty fruit bunch (EFB) biochar, poultry manure compost, and Rock Phosphate (RP) to enhance soil quality and support the growth of one-year-old oil palm plants. The study was conducted over six months in a one-year-old oil palm plantation located in Panca Mulya Village. A randomized Complete Block Design (RCBD) was employed with the aplication of biochar, compost, and rock phosphate (RP = Togo Rock Phosphate, 33.5% P₂O₅) in the following treatments: P0 = control (no treatment); P1 = biochar 20 tons.ha-1 + RP 200 kg.ha-1; P2 = biochar 10 tons/ha + compost 10 tons.ha-1 + RP 200 kg.ha-1; P3 = compost 20 tons.ha-1 + RP 200 kg.ha-1; P4 = biochar 20 tons.ha-1 +compost 10 tons.ha-1 + RP 200 kg.ha-1; P5= biochar 10 tons.ha-1 + compost 20 tons.ha-1 + RP 200 kg.ha-1. Results indicated that the application of biochar, compost, and RP, whether individually or in combination, enhanced oil palm growth compared to the control. The application of biochar and compost improved soil physical properties, increased soil organic matter content, total pore space, available water content, reduced bulk density, soil penetration resistance, and promoted oil palm growth. The best treatment was found to be 10 tons.ha-1 biochar + 20 tons.ha-1 compost + 200 kg.ha-1 RP. Keywords: ameliorant, empty fruit bunch, soil quality

Abstract

Celery (Apium graveolens) is one of the important vegetable crops with export potential. The cultivation of celery in Riau Province tended to be constrained by low soil fertility, particularly due to the dominance of Yellow Red Podzolic (PMK) soils. To address this issue, efforts to improve yields by selecting suitable growing media and fertilizing were necessary. This study was conducted at the experimental farm of the Faculty of Agriculture, Universitas Lancang Kuning, located on Jl. Yos Sudarso Km 8, Rumbai, Pekanbaru. The site had flat topography, an elevation of 16 meters above sea level, and Yellow Red Podzolic soil. The study was conducted over four months, from July to October 2024. The research used a factorial Completely Randomized Design (CRD) with two factors: M (growing media) with four levels and G (Growmore liquid fertilizer) with four levels. Each treatment was replicated three times, resulting in 48 experimental plots. Each plot contained four plants, with two plants used as samples, giving a total of 192 plants and 25% extra as reserve plants. Based on the analysis of variance, both the composition of the growing media and the concentration of Growmore had significant effects on all observed parameters, which included plant height, number of petioles, plant weight, root volume, and number of tillers. Further analysis showed that the interaction between growing media composition and Growmore concentration significantly affected all treatments. The lowest growth was observed in treatment M0G0 (no media composition and no Growmore fertilizer). At the same time, the highest performance was recorded in treatment M3G3 (PMK soil + rice husk charcoal + goat manure at a 1:1:2 ratio and Growmore fertilizer at 3 g/L).

Abstract

Durian (Durio zibethinus Murr.) is an exotic tropical fruit with a unique taste and aroma. Durian fruit, also called the king of fruits, is very popular among various communities for its distinctive taste. Vegetative propagation techniques used by farmers remain less efficient, both in terms of time and implementation, so the ability to provide superior durian seeds remains limited, and the price is relatively high. One technique involves using compost and liquid organic fertilizer TOP G2, which also helps rehabilitate, improve, and maintain the fertility of cultivated land, thereby significantly increasing plant growth and quality. This research was conducted experimentally using a Completely Randomized Design (CRD) factorial with two factors: K (dry leaf compost) with 3 levels and T (POC TOP G2) with 3 levels, each with 3 replications. The number of experimental units is 27 plots. Each plot consists of 4 plants, with 1 plant as a sample, for a total of 27 × 4 = 108 plants. The analysis of variance showed that providing dry leaf compost and POC TOP G2 had a significant effect on the observation parameters of stem diameter, leaf length, and leaf width but had no significant effect on plant height or leaf number. The results of the best further treatment tests were in the K2T2 treatment (provision of dry leaf compost 2 kg/plant and provision of POC TOP G2 10 cc/l plant) and K1T2 (provision of dry leaf compost 1 kg/plant and POC TOP G2 10 cc/l plant). The lowest treatment was K0T0 (without the provision of dry leaf compost and POC TOP G2).
