Drought Resistance Of Several Local Upland Rice Genotypes (Oryza sativa L.) From West Sumatra Province
Full text linkRice is a major staple food for the Indonesian population, therefore, its productivity must be improved to accomplish the domestic consumption. Efforts to increase rice production in a sustainable manner in the future not only rely exclusively on lowland rice production but also from other genotypes including upland rice. West Sumatra is one of the province in Indonesia that preserves various local upland rice germplasm. The characterization of local upland rice genotypes to drought stress are required in order to support the increase of national rice production. This study aims was to obtain the West Sumatra local upland rice genotypes that are resistant to drought. The drought resistance screening was carried out in three ways, namely: 1) Testing of seed resistance with Polyethylene Glycol (PEG), 2) Testing of root penetration using a wax coating, and 3) Testing of proline content. From the study, two genotypes, namely: Susun Porti and Ladungan which have good resistance to drought
Optimization of Liquid Organic Fertilizer Concentration of Banana Stem on Cucumber Plant Growth (Cucumis sativus L)
Full text linkCucumber (Cucumis sativus L.) is a vegetable from the Cucurbitaceae family. Cucumbers are fruit vegetables that offer numerous benefits in people’s daily lives, leading to a high demand for this commodity. This fruit is popular across all levels of society, necessitating a relatively large and sustainable supply. This study examined the growth of cucumber plants under the influence of banana stem liquid organic fertilizer (LOF). The research employed a non-factorial Randomized Block Design (RAK) with two replications to assess how banana stem LOF impacts the growth of cucumber plants. Six treatment doses were used: 0 (control), 30%, 35%, 40%, and 45%. The results revealed that plants treated with a 200ml dose of LOF exhibited a higher growth rate than other doses. At the same plant age, the tallest plants were observed at the 200ml dose, while the lowest number of leaves was recorded at the 0 dose. The study identified that applying a 200ml dose of LOF at 5MST significantly impacted plant growth compared to other treatments. The findings suggest that a 200ml dose of banana stem LOF is highly suitable for promoting the growth of cucumber plants. These results can serve as a guideline for achieving optimal cucumber plant growth
The Effect of Rabbit Urine LOF and NPK Fertilizer on Green Bean Plants (Vigna radiata L.)
Full text linkGreen bean plants (Vigna radiata L.) are a staple food crop in Indonesia and are commonly consumed as legume food crops. Based on the Directorate General of Food Crops findings, there has been a decrease in the yield of green bean crops in Riau Province; therefore, measures must be taken to enhance productivity—green bean plant cultivation in the Riau Province. One potential method for improving the productivity of green bean plants involves the application of fertilizers. This study aimed to evaluate the impact of the interaction between liquid organic fertilizer rabbit urine and NPK fertilizer, as well as the individual effects of liquid organic fertilizer rabbit urine and NPK fertilizer, on the growth and yield of green bean plants (Vigna radiata L.) to determine the optimal treatment combination. The findings indicated no statistically significant impact on the development and production of green bean plants due to the combined application of rabbit urine LOF and NPK. The Rabbit urine Point of Concern (LOF) factor substantially impacts plant growth, including height, the abundance of productive branches, the number of full pods, and the weight of dry seeds per plot. The NPK fertilizer factor significantly influences various aspects of plant growth and productivity, including plant height, leaf count, root nodules effectiveness, branch productivity, pod yield, and seed weight per plot. The optimum treatment combination of 200 ml.l-1 rabbit urine POC and 300 kg.ha-1 NPK fertilizer has been found to enhance green bean plants' growth and yield significantly
Induction and Regeneration of Ginger Callus (Zingiber officinale) in Malaysia by Administration of 2,4 D and NAA
Full text linkGinger (Zingiber officinale) is a valuable medicinal plant widely used in food and health industries. This study, conducted at the Malaysian Agricultural Research and Development Institute (MARDI) in September 2024, aimed to assess the impact of hormone concentrations on ginger callus yield and regeneration. The study employed a factorial design with two factors and three replications. The first factor involved MS 24-D media at doses of 0.5 mg/L, 1.0 mg/L, 3.0 mg/L, and 5.0 mg/L. The second factor included Naphthaleneacetic Acid (NAA) at doses of 0.5 mg/L, 1.0 mg/L, 3.0 mg/L, and 5.0 mg/L. Thidiazuron (TDZ) was also used as an additional growth regulator hormone to influence callus formation. The results indicated that growth regulator hormones such as 2,4-dichlorophenoxyacetic acid (24-D), NAA, and TDZ significantly enhanced callus formation efficiency, increasing callus weight. NAA treatment was particularly effective in increasing callus weight. The phenolic content analysis revealed that brown callus exhibited strong defense mechanisms due to a high accumulation of phenolic compounds. Phenolic compounds, known for their antioxidant and antibacterial properties, enhance plant resilience to environmental stress and hold promise for pharmacological applications. Incorporating TDZ in ginger culture demonstrates the potential for improving callus quality with high phenolic content, offering opportunities for agricultural applications

Fermentation yields environmentally friendly enzymes and other functional components beneficial for agriculture. Eco enzymes offer various advantages for shallot plants, including enhanced growth and increased shallot production. This study aims to investigate the effects of watering frequency and Eco enzyme concentration on the growth and yield of shallots (Allium cepa L.). A randomized block design (RBD) was employed, incorporating two treatment factors: the watering timing and the eco enzyme concentration. The treatment factors are as follows: Factor I, Watering Time (W), consists of three treatment levels: 1 time per day, 1 time every two days, and 1 time every three days. Factor II, Concentration of Eco Enzyme (E), includes three treatment levels: 0.8 ml per 240 ml of water per plant, 1.6 ml per 240 ml of water per plant, and 2.4 ml per 240 ml of water per plant. The observed variables in this study were the number of tubers per sample (cloves), the fresh weight of tubers per sample (grams), and root length (centimeters). The results indicated that both the timing of watering and the application of eco-enzyme concentrations significantly affected the number of tubers per sample, the fresh weight of tubers per sample, and root length
Agronomic Characteristics of Three Superior Varieties of Rice Plants (Oryza sativa L. ) At Different Planting Distances in the System of Rice Intensification (SRI) Pattern System
Full text linkThe increasing population necessitates a corresponding rise in rice production each year, a condition significantly influenced by cultivation practices and the application of technology. This study aims to evaluate the agronomic characteristics of three superior rice varieties at different planting distances within the System of Rice Intensification (SRI) framework. The research will be conducted in Geulumpang Payong Village, Jeumpa District, Bireuen Regency, at an altitude of approximately 0 to 969 meters above sea level (masl) from August to November 2024. This study employed a split-plot design (RPT) experimental method within a randomized block design (RAK). Two factors were tested: varieties (Ciherang, Inpari 49, and Mustajab) and planting distances (25 cm x 25 cm as the control, 25 cm x 30 cm, 30 cm x 30 cm, and 35 cm x 35 cm). Consequently, 12 treatment combinations were established, with each treatment replicated three times, resulting in a total of 36 experimental units. Each plot contained four research plants, leading to a total of 144 plants. The data obtained from the research were statistically analyzed using the F-test with SAS V9.12 software. If the results of the analysis of variance indicated significant differences at the 5% level, the Duncan Multiple Range Test (DMRT) was conducted. The results suggested that the variety had a considerable influence on the parameters of plant height and the number of leaves. In contrast, leaf area, root length, and the number of tillers did not show significant effects. In terms of planting distance, the number of leaves and tillers was significantly affected, while plant height, leaf area, and root length did not exhibit significant changes. The interaction between the two factors had a substantial impact on the number of leaves, while plant height, leaf area, root length, and the number of tillers showed no significant effects. The Ciherang variety, combined with a planting distance of 30 cm x 30 cm, emerged as the most effective treatment, indicating it was the optimal condition in this study
Application of Dolomite on The Growth And Yield of Various Rice Genotypes (Oryza sativa L.) Grown on Peat Soil
Full text linkRice is the primary staple food for the Indonesian population. However, land use changes have increasingly limited the availability of potential land for rice cultivation. Indonesia possesses vast areas of peatland, which offer significant opportunities for rice extensification. Nonetheless, the acidic and nutrient-poor nature of peat soils necessitates soil improvement efforts through the application of soil ameliorants. Dolomite is one such ameliorant that can enhance the chemical properties of soil and improve nutrient uptake by plants. This study aimed to evaluate the interaction between rice genotypes and dolomite application rates on the growth and yield of several rice genotypes cultivated on peatland. The experiment was conducted from June to December 2024 in Sunur Village, Nan Sabaris District, Padang Pariaman Regency, Indonesia, using a Split Plot Design in a randomized complete block layout with three replications. The results showed that the genotype and dolomite application significantly affected several agronomic parameters, particularly the 1000-grain weight. Genotypes Bujang Marantau and Caredek exhibited superior performance in most yield components. Dolomite application at 10 tons/ha proved to be the most effective dose, enhancing plant growth and productivity under peat soil conditions. These findings offer practical recommendations for optimizing rice production on marginal peatlands and promoting sustainable agricultural development in Indonesia

Full text linkAgricultural development on peatlands requires a careful and thoughtful approach. Therefore, conducting an inventory of their characteristics is essential for ensuring proper utilization and effective planning. This study aims to analyze the characteristics of peat soils in Lubuk Sakat Village, Kampar, Riau, which are planted with oil palm at various maturity stages, covering a potential peatland area of approximately 800 hectares. The research was conducted using observational and descriptive methods, with purposive sampling employed at peatlands of fibric, hemic, and sapric maturity stages. The observed soil characteristics included pH, organic carbon (C-Organic), available phosphorus (P-Available), and cation exchange capacity (CEC). In addition to these chemical properties, the soil microbial population was also assessed. The results revealed that soil pH, C-Organic, and CEC were similar across the three maturity stages, while P-Available was higher in sapric and hemic peat compared to fibric peat. The microbial population was found to be highest in sapric peat, followed by hemic peat, and lowest in fibric peat. These findings are expected to provide a solid foundation for managing fertilization and improving oil palm productivity on peatlands with similar characteristics
Comparison of the Success of Guava Stem Cuttings (Psidium guajava) Using the Chemical Liquinox Start (Vitamin B1), Root Up, and Natural Ingredients of Red Onion (Allium cepa L)
Full text linkGuava (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
