Abstract

Grumusol soil has considerable potential for crop cultivation; however, its productivity is often constrained by unfavorable physical and chemical properties. This study evaluated the effects of different vermicompost sources and Grumusol soils from two land-use types on the growth and nitrogen (N) uptake of sweet corn (Zea mays L.). A two-factor factorial Completely Randomized Design (CRD) with three replications was employed. The first factor comprised four vermicompost treatments: no vermicompost (control), chicken manure vermicompost, cattle manure vermicompost, and market waste vermicompost. The second factor was Grumusol soil collected from paddy fields and dryland. Plant height, leaf number, stem diameter, fresh biomass, dry biomass, and nitrogen uptake were measured. Data were analyzed using analysis of variance, followed by the Least Significant Difference (LSD) test at the 5% significance level. Vermicompost source significantly affected plant height at 35 days after planting (DAP) and nitrogen uptake. Market waste vermicompost produced the highest nitrogen uptake, whereas cattle manure and market waste vermicomposts resulted in greater plant height at 35 DAP than the other treatments. Grumusol soil origin significantly affected plant height, stem diameter, fresh biomass, dry biomass, and nitrogen uptake but had no significant effect on leaf number. Sweet corn grown in Grumusol soil from dryland exhibited superior vegetative growth and nitrogen uptake compared with plants grown in Grumusol soil from paddy fields. These findings suggest that market waste vermicompost, particularly when applied to Grumusol soil from dryland, can serve as an effective nutrient management strategy for improving sweet corn growth and nitrogen uptake.

Abstract

Titan arum (Amorphophallus titanum (Becc.)) is an endemic flora of Sumatra whose population has declined, placing the species at risk of extinction. Conservation efforts through in vitro culture are needed to support its preservation. In medium-term in vitro conservation, plantlet growth must be suppressed to prolong subculture intervals, reduce contamination risks, and lower maintenance costs. This study aimed to determine the optimum concentration of paclobutrazol for suppressing the shoot growth of A. titanum under in vitro conditions. The research was conducted from October 2024 to May 2025 at the Tissue Culture Laboratory, Universitas Andalas. The experiment was arranged in a randomized complete block design with four concentrations of paclobutrazol: 0, 1, 2, and 3 mg L⁻¹. Each treatment was replicated three times, resulting in a total of 12 experimental units. Data were analyzed using analysis of variance (F-test) at the 5% significance level, followed by Duncan’s Multiple Range Test (DMRT) at the 5% level when significant differences were detected. The results showed that paclobutrazol at 3 mg L⁻¹ was the most effective treatment for suppressing shoot height increment of A. titanum, resulting in a growth increase of only 0,2 cm and 0.17 cm. These findings indicate that paclobutrazol has potential as a growth-retarding agent for the medium-term in vitro conservation of A. titanum.

Abstract

Seed-borne diseases caused by Colletotrichum and Fusarium can reduce the viability and vigor of chili seeds. An environmentally friendly alternative for disease management is the use of Trichoderma atroviride as a biopriming agent. This study aimed to evaluate the effectiveness of T. atroviride biopriming on the germination of Kopay chili seeds infected with Colletotrichum scovillei and Fusarium oxysporum. The experiment was arranged in a Completely Randomized Design (CRD) consisting of eight treatments with four replications. Observed parameters included germination percentage, root length, shoot length, fresh weight, dry weight, vigor index, and root emergence time. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that T. atroviride treatment produced the highest germination percentage (100%), which was not significantly different from the positive control (95%) and negative control (90%). The T. atroviride treatment also resulted in the greatest root length (2.54 cm), shoot length (1.74 cm), highest vigor index (100%), and the fastest root emergence (2 days). In contrast, the C. scovillei treatment exhibited the lowest germination percentage (30%) and vigor index (45%). These findings suggest that biopriming with T. atroviride has the potential to enhance seed vigor and support early seedling growth of chili under seed-borne pathogen stress.

Abstract

Peanut (Arachis hypogaea L.) is an important food commodity with considerable potential for further development. Increasing peanut productivity can be achieved through the selection of suitable varieties and soil fertility management, including dolomite application. This study aimed to evaluate the responses of several peanut varieties to different dolomite rates in terms of plant growth and yield. The experiment was conducted using a factorial Randomized Complete Block Design (RCBD) with two factors, namely three peanut varieties (Zebra, Putih, and Merah) and five dolomite rates (0, 0.25, 0.5, 1, and 1.5 t ha⁻¹), with three blocks. The observed variables included vegetative growth, biomass, yield components, pod characteristics, and productivity. Data were analyzed using analysis of variance, followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level when significant effects were detected. The results showed that variety had a greater influence on peanut growth and yield than dolomite rate. The Zebra variety showed the best plant height growth, whereas the Putih variety showed superior performance in terms of leaf number, pod formation, pod weight, and productivity. Dolomite application had limited effects on several growth and pod size characteristics but did not significantly affect total pod number, pod weight, or productivity. These results indicate that variety selection can be a primary consideration for improving peanut productivity, while dolomite application should be adjusted to soil conditions and plant requirements.

Abstract

Malapari (Pongamia pinnata (L.) Pierre) is a potential source of bioenergy feedstock and a species suitable for land rehabilitation, making the production of high-quality seedlings an important aspect of its development. Seedling growth is influenced by environmental conditions, particularly light intensity, as well as nutrient availability. This study aimed to analyze the effects of light intensity and NPK fertilizer rates on the growth of malapari seedlings and to determine treatments that support optimal seedling growth. The experiment was conducted using a factorial design with two light intensity levels, 100% and 50%, as the first factor and three NPK fertilizer rates, 0, 4, and 8 g/plant, as the second factor. The observed variables included plant height, stem diameter, number of leaves, shoot dry weight, root dry weight, and shoot-to-root ratio. The results showed that light intensity significantly affected plant height, stem diameter, number of leaves, shoot dry weight, and root dry weight, but had no significant effect on the shoot-to-root ratio. Overall, malapari seedlings grown under 100% light intensity exhibited better growth than those grown under 50% light intensity. NPK fertilizer rate significantly affected only shoot dry weight. Under 100% light intensity, seedlings without NPK fertilizer had higher shoot dry weight than those receiving 8 g/plant but did not differ significantly from those receiving 4 g/plant. Under 50% light intensity, 4 g/plant NPK resulted in higher shoot dry weight than the control but did not differ significantly from 8 g/plant.

Abstract

Growing media play an important role in the growth of katuk cuttings. This study aimed to evaluate the growth of cuttings from three katuk accessions originating from Cianjur under different growing media compositions. The experiment was conducted using a factorial Completely Randomized Design (CRD) with three replications. The first factor was katuk accession, namely Sukaresmi1, Sukaresmi2, and Gekbrong, while the second factor consisted of four growing media compositions: 100% soil, 50% soil + 50% cocopeat, 50% soil + 50% rice husk charcoal, and 50% rice husk charcoal + 50% cocopeat. The observed variables included growth characteristics, rooting characteristics, biomass production, leaf area, stomatal density, and total soluble solids (TSS). Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% significance level. The results showed that Sukaresmi2 exhibited the best performance in terms of shoot number, leaf number, leaflet number, and root length. The 100% soil and 50% soil + 50% rice husk charcoal media provided the best growth responses, particularly in plant height, total shoot length, leaf number, and root number. The highest TSS content was obtained in plants grown in 100% soil, whereas Gekbrong consistently produced the largest leaf area across all growing media. The highest biomass production was obtained from Sukaresmi2 grown in 50% soil + 50% rice husk charcoal, as indicated by the highest fresh and dry weights. These findings indicate that a 50% soil + 50% rice husk charcoal mixture has potential as an effective growing medium for improving katuk growth and biomass production, particularly for the Sukaresmi2 accession.
