Abstract

Eggplant (Solanum melongena L.) is an important horticultural crop with high economic value and is widely cultivated in various regions due to increasing demand. This study aimed to determine the effects of gibberellin (GA3) concentration and eggplant varieties on the growth and yield of eggplant (Solanum melongena L.). The research was conducted in Kolomayan Village, Wonodadi District, Blitar Regency, from February to May 2025. A Completely Randomized Design (CRD) with a factorial arrangement of two factors was used. The first factor was gibberellin concentration at 0 ppm, 100 ppm, 200 ppm, and 300 ppm. The second factor was the eggplant variety, including Hitavi, Mustang, Pulus, and Teho 555. Parameters observed included vegetative and generative growth traits. The results showed a significant interaction between 200 ppm GA3 concentration and the Hitavi variety on total harvested fruit weight. The 200 ppm GA3 treatment alone produced the best results across all observed parameters. The Teho 555 variety excelled in plant height and leaf number, while the Hitavi variety outperformed others in flower number, total fruit number per plant, total fruit weight per plant, and fruit set.

Abstract

Cantaloupe (Cucumis melo var. Cantalupensis L.) is a high-value horticultural crop, popular among consumers for its sweet taste and distinctive aroma. Hydroponic cultivation of cantaloupe using a drip irrigation system offers a promising solution to overcome land limitations, particularly in urban areas. The success of this system is largely influenced by the type of planting medium and the provision of appropriate nutrients. This study aimed to evaluate the effects of different combinations of planting media and seaweed extract doses on the growth and yield of cantaloupe plants. The experiment was conducted from October to December 2024 at the Puspa Lebo Greenhouse, Lebo Village, Sidoarjo District, Sidoarjo Regency, located at an altitude of 4 meters above sea level, with daily temperatures ranging from 26.9°C to 30.4°C. A completely randomized design (CRD) with two factors was used: planting media (cocopeat, rice husk charcoal, and a mixture of cocopeat and rice husk charcoal) and seaweed extract doses (0, 5, 10, and 15 g/plant). The results indicated that cocopeat as a planting medium had a significant positive effect on fruit weight. Additionally, a seaweed extract dose of 5 g/plant significantly enhanced vegetative growth parameters, including plant length and leaf number. In the generative phase, a dose of 10 g/plant significantly influenced the timing of flower emergence and harvest age.

Abstract

Lapindo mud (LL) contains various heavy metals, including copper (Cu), with concentrations exceeding environmental quality standards, thereby posing a risk of soil and ecosystem contamination. One effective method to mitigate this pollution is phytoremediation using hyperaccumulator plants. This study aims to (1) assess the effect of mixing Lapindo mud with soil on Cu levels in the planting medium and (2) determine the optimal planting medium composition for Cu uptake by land spinach (Ipomoea reptans Poir). The experiment involved four planting medium treatments: 100% mud, soil:mud = 1:1, soil:mud = 1:2, and soil:mud = 1:3, each weighing 600 grams per polybag. Plants were harvested at 10 and 20 days after planting, and Cu levels in the soil and plants, bioaccumulation, and growth parameters such as plant height and dry weight were analyzed. Data were subjected to ANOVA at a 5% significance level, followed by the Least Significant Difference (LSD) test. Results indicated that mixing Lapindo mud with soil reduced Cu content in the planting medium, with the lowest Cu concentration in the 1:1 soil:mud treatment (25 ppm) and the highest in the 1:3 treatment (29 ppm). The 1:1 treatment also resulted in the highest Cu uptake (10.17 ppm) and a bioaccumulation index of 0.40, identifying it as the most effective composition for Cu phytoremediation. These findings highlight the potential of land spinach as a phytoremediator to reduce Cu pollution in soils contaminated with Lapindo mud.

Abstract

Okra (Abelmoschus esculentus) is a horticultural crop rich in minerals, antioxidants, polyphenols, and flavonoids. One of the limiting factors for okra production is inadequate nutrition. The use of Plant Growth-Promoting Rhizobacteria (PGPR) and gibberellins is a promising approach to enhance okra production. This study aimed to determine the optimal concentrations of PGPR and gibberellin combinations for improving the growth and yield of okra. The experiment was conducted from March to June 2025 at the Experimental Field of the Faculty of Agriculture, Veteran National Development University, East Java. A factorial experiment was designed using a Randomized Block Design (RBD) with two factors: PGPR concentration at four levels (0 ml/l, 10 ml/l, 15 ml/l, and 20 ml/l) and gibberellin concentration at four levels (0 ppm, 100 ppm, 150 ppm, and 200 ppm), resulting in 16 treatment combinations, each replicated three times. The interaction between PGPR and gibberellin treatments significantly affected plant height and the number of flowers. The 20 ml/l PGPR treatment had the most significant positive effect on the number of leaves between 28 and 49 days after planting and on fruit weight during the 1st, 3rd, and 5th harvests. The 200 ppm gibberellin treatment significantly accelerated flower emergence, with an average of 35.39 days to flower emergence. The combination of 20 ml/l PGPR and 200 ppm gibberellin was the most effective treatment for enhancing okra plant growth and yield.

Abstract

Efforts to improve the quality of the Anjasmoro soybean variety (Glycine max L. Merrill) include the use of seed coating techniques. Seed coating involves applying a layer of specific materials to seeds, serving as carriers for additional substances that extend seed shelf life, protect against pathogens, and stimulate plant growth. This study aimed to identify the most effective seed coating material to enhance soybean growth after storage for three months. Growth tests were conducted using the following treatments: FP 0 (control); FP 1 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Gypsum 18 g); FP 2 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Talc 18 g); FP 3 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Pumice stone 18 g); FP 4 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Quicklime 18 g); FP 5 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Dolomite 18 g); and FP 6 (CMC 1.5% + Liquid Smoke 0.5% + CaCO₃ 72 g + Zeolite 18 g). Observations included plant height (cm), number of leaves, and number of branches. The study was conducted from April to October 2024 at the UPT Center for Rice and Secondary Crops Seed Development 2, Singosari District, Malang, using a randomized block design (RAK) with seven formulations of seed coating materials. Each treatment consisted of 16 plants with four replications. The research data were analyzed using ANOVA, followed by a BNJ (Honestly Significant Difference) test at the 5% significance level (BNJ 0.05). The results showed that the FP 1 treatment resulted in a plant height of 56.50 cm, 19.75 leaves, and 4.75 branches at 35 days after planting (DAP). The FP 1 treatment significantly enhanced growth, as indicated by plant height, leaf number, and branch number. FP 1 demonstrated the best combination of seed coating materials compared to other treatments at 21, 28, and 35 DAP

Abstract

Mung bean (Vigna radiata L.) is an important source of plant-based protein; however, its production has been declining. Efforts to increase mung bean production can be achieved through land extensification and intensification. Extensification can be implemented by utilizing Ultisol soils, while intensification can be accomplished through the application of fly ash and organic amendments. This study aimed to evaluate the effects of fly ash and organic amendments on the growth and yield of mung bean (Vigna radiata L.) grown on Ultisol soil. The experiment was conducted at the experimental field and Soil Laboratory of the Faculty of Agriculture, Riau University, using three fly ash rates and four organic amendments. Data were statistically analyzed using analysis of variance (ANOVA), followed by Duncan's New Multiple Range Test (DNMRT) at the 5% significance level, using SAS software. Observed parameters included the number of filled pods, percentage of filled pods, dry seed weight per plant, root volume, and percentage of effective root nodules. The results showed that fly ash application increased soil pH and organic carbon content while reducing exchangeable aluminum (Al-dd). The application of cattle manure at different fly ash rates significantly increased the number and percentage of filled pods, dry seed weight per plant, root volume, and the percentage of effective root nodules. Fly ash application at rates of 12.5 and 25 g per polybag did not result in significant differences in the number of filled pods, percentage of filled pods, dry seed weight per plant, or root volume compared to the control, but it did significantly increase the percentage of effective root nodules. Overall, applying 25 g of cattle manure per polybag resulted in higher mung bean growth and yield on Ultisol soil than cattle urine or cattle manure bokashi across various fly ash rates.

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading commodities, significantly contributing to the national GDP, foreign exchange earnings, and tax revenues. As the world’s largest producer and exporter of crude palm oil (CPO), Indonesia’s palm oil industry plays a strategic role in maintaining economic stability and global competitiveness. Oil palm productivity is influenced by various factors, including soil chemical properties, particularly in mineral soils with varying fertility levels. This study aims to analyze the effect of soil chemical properties on oil palm fresh fruit bunch (FFB) production in Rokan Hulu Regency, Riau Province. The parameters analyzed include soil pH, organic matter content, cation exchange capacity (CEC), base saturation (BS), and macronutrient availability (nitrogen, phosphorus, potassium). The research methodology involves secondary data collection from plantation companies, multiple linear regression analysis, and Duncan's test to determine the effect of each soil parameter on oil palm production. The results indicate that soil chemical properties, including pH, CEC, BS, nitrogen, phosphorus, and potassium, significantly affect oil palm productivity. Optimal production was observed in soils with a pH of 4.9–6.5, high CEC (>3.8 cmol(+)/kg), and base saturation above 16.3%. The low nutrient content at the study site highlights the need for soil fertility management through liming and organic fertilizers. The study outputs include soil chemical property maps, soil-parameter-based models for predicting oil palm production, and recommendations for mineral soil management to optimize production.

Abstract

The increase of heavy metal content in post-mining land is one of the main challenges in using tin mine tailings for agricultural activities. This study aimed to determine lead changes (Pb) concentrations in tin mine tailings after the application of Faba (fly ash–bottom ash) and the cultivation of peanut (Arachis hypogaea L.), and to evaluate the potential for Pb accumulation in peanut seeds. The experiment was conducted using five levels of Faba application (0; 15; 30; 45; and 60 tons/ha) on tin mine tailings, followed by peanut cultivation for one growing season. The results showed that Faba application increased total soil Pb concentration from 0.09 mg/kg (without Faba) to 19.58 mg/kg (60 tons/ha). However, after peanut cultivation, soil Pb content in all treatments decreased to below the AAS detection limit (< 8.73 mg/kg). Analysis of peanut seeds revealed that Pb levels were also below the detection limit (< 0.165 mg/kg), indicating no significant Pb accumulation in the seeds. This study demonstrates that applying Faba at certain doses can modify the chemical characteristics of mine tailings, and that peanut cultivation has the potential to reduce soil Pb levels through absorption and immobilization mechanisms. The key finding of this study is that combining Faba application at 30–45 tons/ha with peanut cultivation effectively reduces soil Pb content without increasing contamination in harvested seeds. Furthermore, peanut seeds remain safe for consumption due to their very low Pb concentration. Therefore, integrating Faba-based amelioration with the cultivation of excluder or phytoremediation plants, such as peanuts, is recommended as an environmentally friendly tailings reclamation strategy that supports sustainable food security.

Abstract

Lettuce is a popular leafy vegetable among the community. The expansion and potential of lettuce cultivation require efficient growing techniques. The production of plants using a hydroponic system is closely linked to the availability of nutrient solutions. This study aimed to examine how various fertilizer formulations affect the macronutrient (P, K, Ca, Mg, S) and micronutrient (Fe, Zn, Mn, Cu, B) content of hydroponically grown lettuce plants. A completely randomized design (CRD) was employed, and the Wet Digestion Method was used to prepare dry plant samples by breaking them down with a mixture of strong acids and heat. Nutrient concentrations were then analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Statistical analysis of the nutrient data was performed using ANOVA to identify significant differences between treatments. The results indicated that the AB fertilizer and the O38 treatment were the most effective in increasing the majority of nutrients in the plants. Fertilizers with the highest phosphorus content were observed in the AB and O38 treatments, while the highest potassium content was found in the AB and O39 treatments. The highest calcium (Ca) and magnesium (Mg) levels were also recorded in the O38 treatment, highlighting the formulation’s efficiency in supplying macronutrients. Regarding micronutrients, the highest iron (Fe) content was detected in the O37 treatment, whereas the highest zinc (Zn), copper (Cu), and boron (B) contents were found in the AB treatment. This study demonstrated the superiority of the AB fertilizer, which performed best and most consistently. However, the O38 formulation shows potential as a future alternative to commercial AB fertilizers, pending further improvements.

Abstract

The Kesum plant, scientifically known as Polygonum minus, is a herbaceous species native to Southeast Asia (Malaysia, Indonesia, Vietnam, Thailand) that thrives in damp, waterlogged environments, such as the edges of ditches and lakes. This study aims to investigate the effect of potassium concentration on root growth of Kesum (Polygonum minus) plants grown in a floating raft hydroponic system. The experiment was conducted at the MARDI Greenhouse in Serdang, Selangor, Malaysia, employing a Randomized Block Design (RBD) with five potassium concentration treatments (0, 50, 100, 150, and 200 mg/L) and five replications. Kesum cuttings, each 15 cm in length, were planted in hydroponic containers measuring 1 m × 3 m × 0.3 m, with the nutrient solution adjusted to a pH of 5.5–6.5 and electrical conductivity (EC) of 2.0–2.5 mS/cm. Observed parameters included plant height, stem diameter, canopy area, SPAD value, fresh weight, dry weight, root fresh weight, root dry weight, and root length. Data were analyzed using ANOVA followed by Duncan’s Multiple Range Test (DMRT) at a significance level of 0.05. Results indicated that a potassium concentration of 150 mg/L yielded the highest fresh root weight (31.15 g) and optimal root length (22.31 cm), while a 100 mg/L potassium concentration supported the greatest plant height (82.77 cm). This study offers practical recommendations for farmers and agrotechnologists to apply potassium concentrations of 100-150 mg/L in hydroponic Kesum cultivation to achieve optimal root and vegetative growth and enhance production yields.
