Abstract

Sweet corn (Zea mays L. Var saccharata Sturt) has a high demand in Indonesia, but its productivity is threatened by drought; therefore, it is necessary to analyze its growth under drought stress conditions. This study aims to observe the morphological and physiological responses of sweet corn plants to drought stress and potassium administration. The research was conducted over a three-month period at the experimental garden of the Faculty of Agriculture, University of Riau. A Factorial Completely Randomized Design (RA LF) was used with two factors: drought stress and potassium fertilization. The study consisted of three levels of potassium fertilization, with three replications, resulting in a total of 18 experimental units. The first factor: A1 = everyday; A2 = drought stress. The second factor: K 1 = 2.3 g K 2 O plant -1; K 2 = 2.8 g K 2 O plant -1; K 3 = 180 kg K 2 O ha -1. Analysis of Variance was continued with the Honestly Significant Difference (HSD) test at 5% level. The observed parameters consisted of physiological and morphological factors in sweet corn plants. The study found that drought stress negatively impacted the physiological parameters of sweet corn, including reduced plant water content and increased proline levels. Additionally, drought stress decreased key morphological traits, including plant height, root condition, cob husk weight, cob husk length, and cob husk diameter. However, the application of potassium fertilizer, particularly at a dose of 3.4 g K₂O plant-1, significantly improved the length of the cob husk. Overall, increasing potassium application under drought stress conditions tended to enhance both morphological and physiological parameters of sweet corn.

Abstract

Melon is a horticultural commodity with high sales value in both local and export markets. Consumer demand for sweet, fresh, and high-quality melons continues to rise. This rising demand for melons requires higher productivity. To achieve higher melon productivity, advanced agricultural cultivation technologies are required, including hydroponic melon cultivation. This study aims to determine the effects of planting media and magnesium sulfate fertilizer doses on the growth and yield of hydroponic melons using a drip irrigation system. The study was conducted at the Puspa Lebo greenhouse, Lebo Village, Sidoarjo District, Sidoarjo Regency, East Java, from September to November 2024. The research employed a Completely Randomized Design (CRD) with two treatment factors. The first factor was the type of planting media, consisting of three treatments: rice husk charcoal, cocopeat, and a 1:1 mixture of rice husk charcoal and cocopeat. The second factor was the magnesium sulfate fertilizer dose, with four treatments: 0 g/plant, 15 g/plant, 30 g/plant, and 45 g/plant. The results indicated that the rice husk charcoal planting medium treatment affected the fruit weight parameter. Meanwhile, the Magnesium fertilizer dose treatment of 15 g/plant affected plant length and leaf number. The use of rice husk charcoal as a planting medium increased melon fruit weight, and it is recommended that further research explore its advantages for use with other commodities.

Abstract

Oil palm plantations in Riau Province were commonly found on suboptimal lands, such as Inceptisol soils, which exhibited inherently poor soil chemical fertility. This research aimed to determine the chemical properties of Inceptisol soil in 6- and 8-year-old oil palm plantations. This research was conducted from July to December 2024 at the Oil Palm Plantation, Sub-District Perhentian Raja, Kampar District, Riau. The analysis of soil chemical properties was carried out at the Instrumental Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Padang State University. This research employed a quantitative descriptive method, where data collection was conducted through direct observation and subsequently analyzed in the laboratory. A purposive sampling technique was employed to collect soil samples, where each block was divided into four sampling plots. Within each plot, soil samples were collected and composited from five sub-samples, yielding a total of eight Inceptisol soil samples for subsequent analysis. The following soil parameters were analyzed: pH (H2O), OC, total N, P, K, Ca, Mg, SO4, and CEC. The chemical properties of the Inceptisol at the research sites were characterized by: a pH range of very acidic to acidic, sufficient levels of OC, and total-N, very low levels of total (P and K), excessive of total-Ca, deficient of total-Mg, very low levels of SO4, and moderate to high levels of CEC; there were significant mean differences in soil N, SO4, and CEC, whereas soil pH, OC, P, K, Ca, and Mg levels were not influenced by oil palm age.

Abstract

Guava (Psidium guajava L.) is a tropical plant that holds significant popularity and economic value in Indonesia. Despite its benefits, many Indonesians still face challenges in successfully cultivating guava seeds. Traditionally, guavas are propagated from seeds, which often results in lower-quality fruit. Seed-grown trees may take longer to bear fruit, and the fruit produced may not resemble that of the parent plant. This study aims to evaluate the success rate of guava propagation using stem cuttings treated with two different chemicals—Root Up and Liquinox Start—as well as a natural alternative, shallot extract. The cuttings were treated uniformly across all treatments, and the growth parameters observed included the number of shoots, the number of leaves, and the length of the shoots over two months from April 20 to June 22, 2025. The results indicated a significant difference between the three treatments. Root Up treatment produced the longest shoot growth on average, while Liquinox Start also showed a relatively high rate of shoot development. Shallot extract, a natural alternative, also yielded promising results, offering an environmentally friendly and easily accessible option for guava propagation. While chemical treatments, such as Root Up, led to optimal results in terms of shoot, leaf, and shoot length development, the use of shallots demonstrates that natural ingredients can also provide a sustainable and effective approach to guava propagation. Based on the findings, Root Up is recommended for accelerating guava plant growth, but shallot extract presents a viable, eco-friendly alternative.

Abstract

This research was conducted from October to November 2024 in the greenhouse and laboratory of the Faculty of Agriculture, Science, and Health at Timor University. The purpose of this study was to determine the effect of the interaction between biochar compost residue and tofu waste POC on the growth and yield of pak choy plants. The study employed a completely randomized design (CRD) factorial experiment consisting of two factors. The first factor was biochar compost residue, and the second factor was tofu waste POC residue. The biochar compost factor consisted of three levels: 0% biochar compost, 10% biochar compost (0.4 kg biochar compost mixed with 3.6 kg soil), and 30% biochar compost (1.2 kg biochar compost mixed with 2.8 kg soil). The tofu waste POC factor also had three levels: 0 mL/L water, 100 mL/L water, and 200 mL/L water. These factors resulted in nine treatment combinations, each replicated three times, for a total of 27 experimental units. The results showed no significant interaction between biochar compost residue and tofu waste POC. However, the biochar compost residue alone had a substantial effect on plant growth parameters. This research provides valuable information for agriculture by helping to determine the use of biochar compost as a fertilizer and growing medium in pak choy cultivation, enhancing growth and yield.

Abstract

Tomato plants (Lycopersicon esculentum L.) are among the most widely consumed vegetables worldwide and belong to the Solanaceae family. They represent a vegetable commodity with significant potential for development. This study aims to evaluate the effect of applying empty oil palm bunch ash (ATKKS) on the growth of tomato plants. The research employed a non-factorial Randomized Block Design (RBD) with four treatments and five replications. Data were analyzed using Analysis of Variance (ANOVA), followed by a 5% Duncan's Multiple Range Test (DMRT) for further comparison. The results showed that the Sand Soil Treatment combined with 450 grams of Empty Oil Palm Bunch Ash per polybag was the most effective in promoting vegetative growth. This yield was evidenced by a significant increase in plant height, number of leaves, and stem diameter compared to other treatments. This finding indicates that the combination can optimally supply the nutrients required by plants up to the fourth week. For future research, it is recommended to evaluate the effects of this treatment during the generative phase of plant development and on production yields. Additionally, assessing its effectiveness on other plant species and under various environmental conditions will help broaden its practical application in the field.

Abstract

Sweet potato (Ipomoea batatas L.) is a food commodity with significant potential as an alternative source of carbohydrates. However, damage caused by microbial contamination and quality degradation during storage remains a significant challenge. This study aimed to evaluate the effect of chlorine treatment on sweet potato quality. Chlorine treatment was performed by soaking sweet potatoes in a sodium hypochlorite (NaOCl) solution at a specified concentration for a set duration. Parameters assessed included microbial contamination levels, changes in skin and flesh color, water content, and shelf life. The results demonstrated that chlorine treatment significantly reduced surface microbial populations and slowed the rate of physiological deterioration during storage. Furthermore, chlorination did not adversely affect the physical appearance or organoleptic qualities of the sweet potatoes. Therefore, chlorine treatment can be an effective method for handling sweet potatoes, extending their shelf life and maintaining product quality.

Abstract

Green mustard (Brassica juncea L.) is a popular vegetable among Indonesians across all social classes. It has high nutritional value and is rich in vitamins A, B, C, E, and K. This study aims to determine the effect of liquid organic fertilizer (LOF) on the vegetative growth of green mustard (Brassica juncea L.). The research employed analysis of variance (ANOVA) for data analysis, using a Completely Randomized Design (CRD). If significant differences were found, further testing was conducted using the smallest real difference test. The results showed that treatment with 90 ml/L of LOF derived from bamboo leaf waste consistently produced the best growth results over three weeks of observation, with plant height reaching 21.00 cm, the number of leaves reaching 9.67, and the largest leaf width measuring 6.33 cm. These data indicate that applying 90 ml/l of bamboo leaf waste LOF significantly improves plant morphology and health compared to other treatments, suggesting that this treatment can be an effective strategy to increase the productivity of green mustard.

Abstract

Corn (Zea mays L.) is a grain crop cultivated in Malaysia, where the kernels are primarily used as feed for animals. Malaysia's climate is generally hot and rainy throughout the year, which has a significant impact on the growth of corn plants (Zea mays L.). This study aims to compare the effects of rhizobacteria on the growth rate and physiological responses of corn seedlings. Rhizobacteria are bacteria that have a positive impact on plant growth. Two strains of heat-tolerant rhizobacteria were used to observe their impact on corn growth: Heat-Tolerant Rhizobacteria 1 (HTR1) and Heat-Tolerant Rhizobacteria 2 (HTR2). Corn seedlings were transplanted into polybags and placed in a controlled environment at 38°C for 14 days, with four bacterial treatment levels: T1 (without HTR), T2 (HTR1), T3 (HTR2), and T4 (a combination of HTR1 and HTR2). Physiological analyses and growth rate measurements showed no significant differences among treatments; however, photosynthesis rates were significantly higher in treatments with rhizobacteria (T2, T3, and T4) compared to the control (T1). These findings suggest that rhizobacteria can enhance plant physiological functions and have potential applications for long-term crop improvement.

Abstract

Land conversion from rubber plantations to oil palm plantations is increasingly common in Indonesia, including in Pulau Binjai Village, Kuantan Mudik District, Kuantan Singingi Regency, Riau Province. Land preparation for oil palm plantations can affect soil fertility, particularly nutrient content. This study aims to evaluate the nutrient content in one-year-old oil palm plantations. The methods used in this study included surveys and laboratory analyses. Soil sampling was conducted at 10 locations using purposive random sampling at a depth of 20 cm, with 5 locations sampled using the grid method and 5 using the disc method. Each sample location consisted of 5 subsamples, which were then composited. The results showed that the soil pH in the grid ranged from 5.96 to 6.48 (acidic category), while in the disc it ranged from 6.2 to 6.88 (acidic to neutral category). The organic carbon content in the grid ranged from 2.61 to 3.74 (medium to high category), and in the plate from 2.82 to 4.28 (medium to high category). The total nitrogen content in the grid ranged from 0.20 to 0.25 (low to medium category), while in the plate it ranged from 0.21 to 0.29 (medium category). The C/N ratio in the grid ranged from 11.16 to 17.00 (medium to high category), and in the plate from 10.44 to 14.75 (low to medium category). The key findings of this research include the identification of organic carbon and nitrogen content in the soil, which enables recommendations for the application of organic and nitrogen fertilizers in the study area.
