Abstract

Singgalang cabbage (Brassica oleracea L.) is a local vegetable native to West Sumatra, cultivated in highlands around Mount Singgalang, Tanah Datar. Vegetables from Brassica genus are recognized for their high nutritional value and potential as functional foods. Key secondary metabolites in Brassica species, i.e., phenolic compounds and their derivatives, play a crucial role in antioxidant activity and are essential in promoting health. Light exposure, particularly ultraviolet-B (UV-B, 280-315 nm), can enhance biosynthesis of these compounds. UV-B intensity affects various process in plants including the phenylpropanoid pathway involved in secondary metabolite production. This study aimed to assess the expression of the CHALCONE SYNTHASE (CHS) gene under different UV-B intensities (0.3–3.0 µmol·m-2·s-1, 4 h) and examine the effects of two extreme UV-B intensities (0.3 and 3.0 µmol·m-2·s-1, 4h.d-1) in a controlled environment for 14 days. The results showed that increasing UV-B intensity enhanced CHS expression (1.0 and 3.0 µmol·m-2·s-1 showed thicker bands compared to 0.3 µmol·m-2·s-1, with a faint band in the control). Extreme UV-B exposure reduced chlorophyll content by 35–37% compared to the control, while carotenoids remained unaffected. Anthocyanin accumulation increased under low-intensity UV-B, whereas flavonoid levels were higher under high-intensity UV-B, suggesting different functional roles. UV-B exposure also influenced stomatal number and density in leaf. This preliminary study highlights the significant role of UV-B in enhancing specific metabolites in Singgalang cabbage, supporting its potential as a functional food.

Abstract

Brazilian spinach originated from the American continent and has not been widely cultivated in Indonesia. Its narrow land urban farming development is constrained by low light-intensity conditions that prevent Brazilian spinach from growing optimally. The research aimed to study the effects of shade and cutting length on the growth of Brazilian spinach plants. The research was conducted from December 2023 to January 2024 at the experimental field of the Faculty of Agriculture UMJ. The research used a split-plot design with a randomized complete block design (RCBD) as the environmental design. The treatment used as the main plot was shade consisting of no shade, 45% paranet shade, and 65% paranet shade, while the length of cuttings became a subplot consisting of 5 cm, 7 cm, and 12 cm. The treatment combinations formed are nine, and were repeated 3 times. The results showed that shading increased humidity and decreased temperature and light intensity in the plant microenvironment. At the end of the study, in general, the provision of paranet shade up to 65% did not significantly affect Brazilian spinach plants' growth except for plant height and root length. The cutting length had no significant effect on all observed variables. The use of 5 cm cutting length is recommended because it is considered more efficient in providing cutting material. There were no interaction effects between shade and cutting length on the growth of Brazilian spinach plants.

Abstract

Weeds remain a persistent challenge in agriculture, significantly reducing crop productivity by competing for essential resources such as light, water, and nutrients. Although synthetic herbicides are widely used for weed control, their long-term application raises serious environmental and health concerns. As a sustainable alternative, plant-based bioherbicides that harness allelopathy—the natural chemical interactions among plants—are gaining attention. This review explores recent findings on the allelopathic potential of invasive and native plant species, focusing on key allelochemicals such as flavonoids, phenolics, and terpenoids that exhibit phytotoxic effects on weed species. Genetic factors, including specific quantitative trait loci (QTLs) and metabolic pathways involved in allelochemical production, are also discussed as critical determinants of allelopathic expression. Furthermore, environmental conditions such as temperature, soil composition, and light regimes can influence the efficacy and persistence of allelopathic compounds in the field. Understanding the synergistic interaction between genetics and environmental variables is essential for the development and optimization of effective, eco-friendly bioherbicides. This review highlights the current challenges and prospects in integrating allelopathy into weed management strategies for sustainable agriculture.

Abstract

One of the essential macro nutrients that is highly needed in plant growth because its function cannot be replaced by other nutrients is Potassium. Soybean plants require a high amount of potassium because the growth of soybean plants is greatly influenced by potassium. This study aims to obtain the best dose of Potassium fertiliser for one F7 soybean strain selected from several strains studied so that one selected strain can be obtained. The research was conducted from October 2023 to December 2023, at the Experimental Garden of the Faculty of Agriculture, University of Simalungun with an altitude of 400-500 m above sea level. Factorial Randomised Block Design with two factors was used in this study. The first factor was 5 F7 soybean strains (G) used, namely G1 = F7.5.82.87.166.71.35.1; G2 = F7.5.82.87.166.71.35.2; G3 = F7.5.82.87.166.71.35.3; G4 = F7.5.82.87.166.75.40.1; G5 = F7.5.82.87.184.12.75.38. The second factor of KCl fertiliser (K) used was three levels, namely K1 = 75 kg/ha (18 g/plot), K2 = 150 kg/ha (36 g/plot), K3 = 225 kg/ha (54 g/plot). There were 15 treatment combinations and each combination was repeated 3 times, resulting in 45 research plots. The parameters observed were plant height (cm), number of branches (branches), number of pods per plant (pods), seed weight per plant (g), seed weight per plot (kg) and 100 seed weight (g). If the analysis of variance shows an effect, the analysis will continue using the 5% BNT test. The results showed that the strain F7.5.82.87.166.71.35.2 was the selected strain to be continued because this strain interacted best with the dose of potassium fertiliser 225 kg/ha (54 gr/plot), by producing a large and significantly different correlation value between the number of branches to the number of pods per plant, seed weight per plant and seed weight per plot (0.944**, 0.936**, 0.873**).

Abstract

Sweet corn (Zea mays saccharata Sturt.) is the third largest horticulture group in Indonesia. However, the import rate is still high in Indonesia due to low domestic production. Fertilization and the use of superior varieties are efforts to increase production. However, inorganic fertilizers still dominate maize cultivation. As a result, microorganisms that should be an essential unit in the availability of plant nutrients are threatened. This research was conducted to find out the effect of eco enzyme application and several varieties of sweet corn on increasing sugar content and vitamin C in the field. In this research was used a split plot randomized group design (RGD) with 2 factors and 3 times repetition. The main plot factor in this research was 4 varieties and the subplot factor was 3 levels of eco enzyme concentration. As the results of the research is the varieties of sweet corn plants gave a significant effect on several parameters of observation. Bonanza variety produced better Total Dissolved Solids, while Paragon variety produced better growth and vitamin C characteristics. The concentration of eco enzyme didn’t give an effect on all parameters. Concentration of eco enzyme 20 mI I-1 of water gave better growth characteristics and cob weight. The concentration of eco-enzyme and sweet corn varieties has a most significant interaction on the number of cobs per plot. The best combination was Paragon variety and eco enzyme concentration of 10 mI I-1 of water which made more cobs per plot.

Abstract

Melon have the potential to produce 10-20 fruits per plant; however, the quality of each fruit is often suboptimal due to inefficient assimilate distribution. This study aimed to determine the optimal fruiting branch position to maximize the growth, yield, and quality of melons in a fertigation hydroponic system. The research was conducted in a 168 m² greenhouse owned by PT Lentera Agropedia Nusantara, located in Pripih, Hargomulyo, Kulon Progo, Special Region of Yogyakarta, Indonesia. A split-plot experimental design was used, with melon cultivars (Sweet Hami and Kirin) as the main factor and fruiting branch positions (lower, middle, and upper) as the sub-factor. The results showed that middle (9th to 10th nodes) and upper (11th to 12th nodes) fruiting branches exhibited greater fruit weight, length, and diameter compared to lower branches (7th to 8th nodes). Kirin cultivar had thicker flesh, and the interaction between cultivar and branch position significantly influenced the fruit cavity diameter. Middle and upper branches produced fruits of similar quality when harvested at 70 days after planting. Fruiting on the lower branches (7th to 8th nodes) produces fruits with lower weight, length, and diameter.Considering the risks associated with fruiting on upper branches, it is recommended to maintain melons on middle branches, specifically at the 9th to 10th nodes.

Abstract

Evaluation of kidney bean genotypes in the lowlands is a preliminary step in a plant breeding program to develop lowland-adaptive varieties. This study aims (1) to evaluate agronomic characters, (2) analyze the associations between yield component traits and total yield, and (3) select kidney bean genotypes adapted to lowland environment. The study was conducted in lowlands (185 m asl), Leuwikopo Experimental Station, IPB, Bogor, from March to June 2023. Ten kidney bean genotypes were arranged in a randomized complete block design. Observations included growth characters and yield components, followed by heritability, correlations, and multiple regression. Genotype was significantly affects plant height, total productive bunches, total pods number, total pod weight, total seed weight, and pod length. Characters with high broad sense heritability (h2bs>60%) were plant height, total productive bunches, pod length, total pod weight, and total seed weight. Total seed weight was identified as a selection trait for adaptation in lowland. Adaptive genotypes in the lowlands exhibited high total pod and seed weight, taller canopy, numerous productive clusters, and early maturity. Genotypes KM06, KM03, and KM04 showed the highest total seed weight per plant, indicating superior adaptation potential in lowland environments.

Abstract

Porang (Amorphophallus muelleri Blume) is a significant player in the international market, but its slow seedling growth rate is a major concern. This study, which holds significant implications for porang cultivation, aimed to accelerate the seedling growth phase through the induction of adventitious shoots from callus proliferation. We explored the use of plant growth regulators (PGRs), specifically auxins (NAA and 2,4-D) and cytokinins (BAP), in combination with variations in light color (white and white-blue). The observed parameters included the time of first callus and adventitious shoot emergence, callus growth, number of adventitious shoots, and callus coloration. Data were subjected to two-way analysis of variance (ANOVA) to evaluate the effects of plant growth regulator (PGR) type and light quality as independent variables. Statistical significance was assessed at a 95% confidence level using SPSS software. The combination of 1.0 ppm NAA and 0.5 ppm BAP in MS medium under white-blue light effectively accelerated callus induction from bulbil explants, with visible callus formation by day 8 and the fastest proliferation over 7 weeks. Under white light, the same PGR combination also promoted the earliest adventitious shoot formation by day 16 and yielded the highest number of shoots, totaling seven by the end of the culture period.

Abstract

Coffee is one of the important plantation commodities that plays a significant role in the Indonesian economy. Gold Robusta coffee is a potential genotype currently being developed in Jember, particularly by the University of Jember, as an alternative to the common practice of using seedling cuttings with unidentified genetic origins. This study aimed to determine the optimal nitrogen (urea) dosage containing 46% N and its growth response on immature (TBM) Gold Robusta coffee plants. The research was conducted at the Experimental Field in Darsono Village, Arjasa District, Jember Regency, from May to December 2024. The experimental design used a Completely Randomized Design (CRD) with a single factor, consisting of three levels of urea fertilizer doses, namely 15 g, 30 g, and 45 g/plant, each replicated nine times. Observed variables included plant height, number of leaves, stem diameter, number and length of productive branches, leaf area, and chlorophyll content. Data were analyzed using ANOVA, and significant differences were further tested with Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that urea application significantly affected the growth of immature Gold Robusta coffee. A dose of 45 g/plant produced the best growth performance with an average plant height of 112.78 cm, 21.44 leaves, leaf area of 163.56 cm², and productive branch length of 47 cm. Therefore, urea application at 45 g/plant can be recommended as a fertilizer guideline during the immature phase of Gold Robusta coffee.

Abstract

Tobacco is an important agricultural commodity in Indonesia, but it is vulnerable to drought due to climate change. This study aimed to analyze the physiological response of tobacco plants (Nicotiana tabacum L. 'Bligon') to nitrogen fertilizer application under drought conditions. The experiment was arranged in a Randomized Complete Block Design with a combination of three urea fertilizer doses (0.6; 1.2; 1.8 g/ 5 kg of growing media) and three levels of field capacity levels (100; 75; 50%). Each treatment combines three replications. Parameters observed included plant growth and physiological traits, and the data were analyzed using analysis of variance followed by Duncan’s test at a 5% significance level. The results showed that nitrogen application significantly affected the physiological response of tobacco plant under drought conditions. The 0.6 g nitrogen dose showed a low effect on physiological and growth parameters. The 1.2 g doses moderately increased carotenoids and membrane stability index (MSI). While 1.8 g significantly improved chlorophyll, MSI, and growth parameters. These results indicate a positive correlation between physiological responses and increasing urea doses.
