Abstract

[ENHANCING THE GROWTH AND YIELD OF PAKCHOY THROUGH THE APPLICATION OF COW URINE LIQUID ORGANIC FERTILIZER AND PGPR AT VARYING CONCENTRATIONS]. The employment of plant growth-promoting rhizobacteria (PGPR) has demonstrated potential as a promising method in the adoption of sustainable agricultural practices. This study aimed to determine the developmental and productive aspects of pakcoy under varying exposures to Plant Growth Promoting Rhizobacteria (PGPR) and liquid organic fertilizer derived from cow urine. Conducted experimentally from March to May 2023, the research employed a randomized block method with three replications and two factors. The liquid organic fertilizer from cow urine was administered at four levels: control, 20 mL/L, 30 mL/L, and 40 mL/L. Simultaneously, PGPR was applied at four levels: control, 15 mL/L, 20 mL/L, and 25 mL/L. Results indicated that cow urine significantly influenced parameters such as plant height at 3 WAP (19.98 cm), 4 WAP (22.92 cm), and 5 WAP (23.45 cm), as well as the number of leaves and root length. PGPR, on the other hand, exhibited notable effects on plant height at 4 WAP (24.00 cm) and 5 WAP (23.94 cm), number of leaves, root length, plant fresh weight, and plant dry weight. Notably, the interaction between PGPR and cow urine affected pakchoy growth components, particularly in plant height at 4 WAP and 5 WAP

Abstract

[IMPACT OF RED ONION EXTRACT ON THE GROWTH AND QUALITY RHIZOMES OF YELLOW TURMERIC (Curcuma domestica Val.)]. Turmeric, a member of the Zingiberaceae family, is known for its richness in phenolic compounds with antioxidant activity and is often utilized as a raw material in traditional medicine. However, the productivity of turmeric experiences a decline, and a dormancy period occurs during the dry season, demanding solutions to overcome these challenges. Agricultural intensification is considered an alternative to enhance the growth and secondary metabolite yield by applying natural Plant Growth Regulators (PGRs). Red onion possesses phytohormones that hold potential as natural PGRs. This research aims to evaluate the impact of the most effective of red onion extract in enhancing the growth and rhizome quality of yellow turmeric. The experiment was conducted using a Randomized Complete Block Design (RCBD) with variations in extract concentrations (0%, 2.5%, 5%, 7.5%, and 10%). Variables measured included plant height, leaf count, number of yellow turmeric seedlings, rhizome weight, total phenolic content, and antioxidant activity. Result analysis was carried out using Analysis of Variance (ANOVA), followed by a DMRT test at a significance level of 5%. The findings indicate that the red onion extract significantly affects all observed variables, except for the number of shoots. The 10% red onion extract treatment demonstrated the most positive impact on all measured variables.

Abstract

Efficacy of Lemongrass and Soursop Leaf Extracts for Controlling ArmywOrm (Spodoptera litura J.E. Smith) Infestation in Green Mustard Cultivation]. Employing vegetable insecticide as a primary measure for controlling armyworms (Spodoptera litura) represents an environmentally friendly strategy to enhance yield. This research, conducted between December and February 2021 at the Plant Protection Laboratory and Plant Protection Gauze House, Faculty of Agriculture, Bengkulu University, aimed to determine the effective concentration of vegetable insecticides for managing armyworms infestation in green mustard. A randomized complete design (CRD) with six treatments and five replications was employed for the efficacy test. The treatments comprised: control, lemongrass extract, soursop leaf extract, lemongrass and soursop leaves extracts in a 1:1 ratio, lemongrass and soursop leaves extracts in a 1:2 ratio, and lemongrass and soursop leaves extracts in a 2:1 ratio. The results demonstrated that both lemongrass and soursop leaf extracts, either individually or in combination, effectively controlled S. litura larvae. Notably, an 8% concentration of citronella extract exhibited the highest mortality rate at 60%, with soursop leaves achieving 53.3%. In combination extracts, lemongrass and soursop leaves extracts in 1:1 and 2:1 ratio resulted in a 43.4% larvae control, while the ratio of lemongrass 1:2 to soursop leaves achieved a 36.6% larvae control. Overall, the research underscores the potential of vegetable insecticides, specifically lemongrass and soursop leaf extracts, as viable components of integrated pest management strategies to maintain crop yield in green mustard cultivation.

Abstract

[EFFECT OF BENZYL AMINO PURIN ON SHOOT INDUCTION OF AGLONEMA (Aglonema commutatum Schott.)]. The Aglonema is a well-known ornamental plant and has a high selling value in Indonesia. It is characterized by attractive and beautiful leaves because of its diversity of colors and motifs. The Aglonema commutatum Schott plant is a type of Aglonema which is characterized by green leaves with white markings. The increasing demand for Aglaonema, both imports and exports, makes it impossible to propagate through seeds and cuttings, so it is important to optimize propagation through effective tissue culture. The aim of research was to determine effect of various concentrations of the BAP Benzyl Amino Purin on the shoot induction of A. commutatum plants. The explants used were the stem nodal parts which were planted in Murashige and Skoog media. The research design used CRD with a BAP concentration factor consisting of 6 levels, namely 0 mg/L, 4 mg/L, 8 mg/L, 12 mg/L, 16 mg/L and 20 mg/L. The BAP concentration treatment showed a very significant different effect on the induction of A. commutatum tuna. The 8 mg/L BAP treatment showed the best results with the fastest initial explant response 10.8 dap, the highest number of shoots was 2 shoots/elplant, and the highest shoot was 0.75 cm.

Abstract

[ASSESING GROWTH AND STOMATAL DENSITY OF CULTIVATED SORGHUM PLANTS IN WETLAND ENVIRONMENTS ACROSS DIFFERENT IRRIGATION PATTERNS]. Sorghum cultivation is commonly associated with dry lands, but its potential for development on marginal swamp land remains limited. The wet conditions characteristic of swamp land pose a unique challenge to sorghum cultivation in Indonesia. This study sought to gather preliminary insights into sorghum crop development on swamp land by examining the effects of different irrigation patterns. Conducted at the Bengkulu University Greenhouse from June to August 2022, the research employed a group-randomized design with a single-factor pattern. Four irrigation treatments were administered: saturated water, saturated dry, dry-saturated, and dry. The experimental unit consisted of polybag planting media, repeated four times, with each polybag containing 20 seeds of the Numbu sorghum variety, cultivated until reaching six weeks of age. Irrigation patterns were simulated by placing the polybag media in basins filled with water up to a height of 10 cm. Results revealed varying impacts of irrigation patterns on sorghum growth, with water-saturated, dry-saturated, and dry-saturated patterns leading to superior growth compared to the dry pattern. Notably, sorghum plants cultivated under wet conditions on swamp land exhibited promising growth

Abstract

The synergistic effects of tuber cutting and PGR application on red onion growth and yield have not been extensively studied. Therefore, this study aimed to determine the most effective combination of tuber cutting and plant growth regulator (PGR) application for enhancing red onion growth and yield. Conducted between January and April 2023 in the greenhouse of the Agronomy Department, Faculty of Agriculture, University of Palangka Raya, the experiment utilized a completely randomized design (CRD) with seven treatments, each repeated five times. Treatments included: no cutting, cutting ¼ part of the bulb + 3 mL/L PGR, cutting ¼ part of the bulb + 6 mL/L PGR, cutting ¼ part of the bulb + 9 mL/L PGR, cutting ⅓ part of the bulb + 3 mL/L PGR, cutting ⅓ part of the bulb + 6 mL/L PGR, and cutting ⅓ part of the bulb + 9 mL/L PGR. Results indicate that red onion growth and yield can be significantly optimized through the strategic combination of tuber cutting and PGR application. The treatment involving cutting one-third of the tuber with 6 mL/L PGR concentration yielded the most favorable outcomes. Plants in this treatment displayed an average height of 45.84 cm, 51.4 leaves per plant, 10.6 bulbs per plant, 12.4 tillers per plant, a fresh weight of 42.79 g, a tuber dry weight of 18.34 g, and a bulb diameter of 2.18 cm. These findings suggest that cutting one-third of the bulb, in conjunction with specific PGR concentrations, enhances both yield and nutrient content in red onion bulbs, offering valuable insights for optimizing cultivation practices and maximizing crop productivity.

Abstract

Silica (Si) is a functional element in rice fields that is rarely studied, especially in Solok Regency. Intensive management without a fallow period causes silica to be transported out through high uptake by rice plants. This research aims to determine the distribution of available Si in the highland rice fields in Gunung Talang District, Solok Regency, West Sumatra. The research was carried out using a survey method. Soil samples were taken following the topo-sequence of the area of 600–1,100 meters above the sea level, which consists of 3 groups of rice fields based on height differences, namely the lower, middle, and upper fields. These rice fields have two types of straw management, namely burning and immersing. The research showed that the available Si content was 10.48–293.66 mg/kg  with an average of 133.34 mg/kg. The available Si content is higher in the upper paddy fields compared to the lower and middle paddy fields. Based on differences in straw management, the available Si content is lower in fields with straw buried compared to burned straw. The application of Si fertilizer is highly recommended to obtain the available Si content in the soil.

Abstract

[POTENTIAL OF BIOFERTILIZERS TO INCREASE RICE YIELD IN SWAMP LANDS] Nutrient unavailability is a major problem in swamp land due to flooded and acidic conditions. The use of biofertilizer, which can increase the availability of nutrients, is a solution to increase rice yields in swamp land. This research aimed to find out the improvement of the rice yield with an application of bacteria in biofertilizers in swampy land. One factor tested was the various doses of bacterial biofertilizer consisting of 1, 2, 3, and 4 g/50 g of paddy seeds, without bacteria as a control, arranged in a randomized block design with 3 replications. Rice seeds were soaked for 24 hours, then drained, and biofertilizer was applied as a seed treatment following the treatment doses. Seeding was carried out in trays measuring 15 cm high for 2 weeks. The inorganic fertilizer was applied at 75% of the recommended dose. The variables observed were plant height, number of tillers, number of productive tillers, percentage of empty grain, weight of 1000 seeds, and grain weight. The data observed were analyzed with an ANOVA at the 5% level and further tested with DMRT at the 5% level. The results showed that the bacteria in biological fertilizer can potentially increase the yield of swamp rice plants. A biofertilizer dosage of 4 g/50 g of seeds gave the highest yield in terms of grain weight per hill and per plot, as well as a weight of 1000 grains with an increase of yield of 14.32% compared to control.
