Abstract

The application of granular bioherbicides derived from purple nutsedge (Cyperus rotundus L.) tubers offers an environmentally friendly alternative for managing weed competition in upland rice cultivation. This study evaluated the efficacy of various granular bioherbicide forms and sizes (67.5 kg ha-1) in suppressing weed growth and their impact on upland rice. A completely randomized design with twelve treatments was employed. Results showed that granular bioherbicides effectively controlled broadleaf weeds for up to four weeks without causing phytotoxicity to upland rice. Very small granular bioherbicides (spherical and cylindrical) were the most effective form to suppress weed growth of Alternanthera sessilis (L.) R.Br. ex DC., and Mimosa pudica L., and enhance upland rice growth and yield. Keywords: allelopathy; biological control; efficacy; pre-emergence; sustainable agriculture

Abstract

Bananas are one of Indonesia’s most important horticultural crops, valued for their adaptability and economic potential. Among them, the Roid banana (ABB) (Musa spp.) stands out as a local variety native to West Java-Indonesia, particularly the Jatigede District, Sumedang Regency where it thrives naturally without agronomic inputs. Known for its resistance to pests and diseases, long shelf life, and strong fruit attachment that reduces post-harvest losses, the Roid banana remains underutilized and understudied. Despite its advantages, research on its genetic diversity is limited, highlighting the need for characterization as a foundation for conservation and breeding. This study, conducted from October to December 2023 in the Jatigede District, aimed to analyze the distribution patterns and genetic diversity of Roid bananas. Characterization used a survey method and purposive sampling in situ. Results revealed two primary clusters dominated by accessions from Ciranggem and Jemah Villages. Key traits supported clusters were peduncle curvature, bunch length and density, number of fruit hands, male flower attitude, apex shape, skin color, plant height, and the presence of hermaphrodite flowers. The genetic diversity based on Euclidean distances was 0.47 to 11.92. The Index of Cultural Significance value was 105, implying a very high level of utilization diversity. These findings highlight the genetic richness and cultural importance of Roid bananas, offering valuable insights for future conservation and breeding programs. Keywords: characterization; cluster analysis; exploration; Index Cultural Significance (ICS); Musa spp.

Abstract

Arugula is a member of Brassicaceae that has a high antioxidant content of glucosinolate. Bio-slurry is a kind of liquid fertilizer derived from sap of cow dung. Bio-slurry in combination with rhizobacterial can maximize decomposition and make nutrients more available. The research aimed to determine the total glucosinolate content in arugula due to the application of bio-slurry enriched with rhizobacteria. The study used a randomized complete block design with a single factor consisting of 9 levels, i.e., the combination of 3 types of rhizobacteria (Pseudomonas, Bacillus, Pseudomonas + Bacillus) and 3 doses of bio-slurry (0, 100, and 200 mL). The results showed that the application of Pseudomonas & Bacillus + 200 mL bio-slurry produced a higher antioxidant content than other inputs. The combination of bio-slurry fertilizer with rhizobacterial provides a higher ability than control to increase plant growth rates and the biosynthesis of glucosinolate. The optimal substitution for maximizing nutrient uptake in arugula growth was achieved with a bio-slurry dose of 200 mL, where the combined application of Pseudomonas and Bacillus strains enhanced plant growth and glucosinolate content.

Abstract

Seaweed (Kappaphycus alvarezii) liquid extract contains hormones, and macro and micronutrients that might benefit plant growth and development. This study aimed to evaluate the effect of a biostimulant liquid of seaweed extract on the vigor of rice seedlings. The research was conducted in the experimental field of the Faculty of Agriculture, Halu Oleo University, Kendari, Southeast Sulawesi. A factorial treatment design was conducted with a randomized block design. The first factor was the seedling method (wet sowing (S1) and dry sowing (S2)), and the second factor was six biostimulant concentrations (no biostimulant (K0), 0.8% (K1), 1.6% (K2), 2.4% (K3), 3.2% (K4), and 4.0% (K5)). The observed variables included seedling height, leaf area, number of tillers, root dry weight, and seedling dry weight. Data were analyzed using ANOVA, and DMRT at α = 0.05. The results showed that the wet sowing method produced better seedling vigor than the dry sowing method after 14 days. The wet sowing method combined with a 0.8% seaweed extract resulted in the highest seedling vigor. The present study concluded the biostimulant potential of seaweed extract for rice.

Abstract

Peanuts (Arachis hypogaea L.) is the second most important type of legume after soybeans in Indonesia. Fertilizers were given in either organic or inorganic forms. However, the continuous use of chemical fertilizers was found to have negative impacts on the environment and the microorganisms in the soil. Therefore, organic and biological fertilizers were recommended because they had positive effects on both the environment and the soil’s microorganisms. Some of the bacteria that were beneficial for plant growth were Pseudomonas sp. and Azotobacter sp. This study aimed to analyze the use of organic fertilizers, biological fertilizers, and NPK combinations on the growth and yield of peanut plants of the Takar 2 variety. The study was conducted from March to June 2024, located at the Leuwikopo Experimental Station of IPB, Bogor, Indonesia. The experiment used a randomized complete block design (RCBD) with two factors and three replications. The factors are NPK fertilizer doses (100% and 50% recommended dose) and types of organic + biological fertilizer (control, Azotobacter sp., Pseudomonas sp., humate, and a combination of humate and biological fertilizer). Observations were made on 5 sample plants per treatment. The characteristics observed were plant morphology, physiological characteristics, and plant production. The results of the study showed that the application of 100% NPK fertilizer at the recommended dose, in combination with Pseudomonas sp., Azotobacter sp., and humate, had a significant effect on various morphological, physiological, and production-related plant variables. This study shows the potential for a combination of NPK and organic biological fertilizers to increase the growth and production of peanuts. Keywords: Azotobacter sp; humate; morphology; physiology; Pseudomonas sp

Abstract

Soil amendment is a key factor in improving peat soil suitability for agriculture from the perspective of its fertility and quality. Red mud is potentially used as a peat soil ameliorant. The study aimed to evaluate red mud application as an ameliorant and application of Rhizobium on peat soil for growing edamame. The research was conducted at Tanjungpura University, Pontianak, from February to October 2024. A completely randomized design factorial was used to compile field experiments. The ameliorant factor consisted of 4 levels: control (dolomite 8 tons ha-1) and Red Mud of 10 tons ha-1, 15 tons ha-1, and 20 tons ha-1. The second factor was without and with Rhizobium. The application of Red Mud as an ameliorant increased pH, Na, and P2O5 levels and increased base saturation in peat soil. The Red Mud increased Na absorption in edamame tissues and increased pod yield. The highest edamame yield was reached with 20 tons ha-1 of red mud which was similar to with 8 tons ha-1 dolomite. Rhizobium has a role in supporting the formation of better root nodules. Keywords: crop yield; microorganisms; red mud; soil chemistry; soybean

Abstract

The fluctuations in seed food reserves can trigger a cascade of physiological and biochemical events that ultimately manifest as discernible changes in seed morphology and anatomy.  The purpose of this research was to evaluate seeds morphology, anatomy, and quality of Musa balbisiana “Klutuk NTT” and Musa acuminata “Sumatrana” accessions and their storability. Morphological evaluation included seed size and the weight of 100 grains. Anatomical evaluations were carried out for seed structure. The seed quality of the Klutuk NTT banana accessions was observed after being stored for 5, 25, and 41 months, while the Sumatrana banana accessions were observed after being stored for 5, 23, and 41 months. The Klutuk NTT seeds are sized 4 mm to 5.8 mm, while Sumatrana seeds are sized 4 mm to 5 mm. The Klutuk NTT and Sumatrana seeds had a seed coat, endosperm, embryo, micropyle, inner and outer integuments, chalazal, and operculum. The embryonic structure of both Klutuk NTT and Sumatrana seeds exhibited an inverted T-shape. After storage, the two accessions showed significant differences in moisture content, germination rate, vigor index, and seedling growth performance. The Klutuk NTT accessions demonstrated a significant increase in moisture content, germination rate, vigor index, and seedling emergence uniformity, suggesting improved seed performance after storage. In contrast, the Sumatrana accessions showed a significant decline in all measured parameters, except for moisture content. These results suggest that the Klutuk NTT accession may possess a physiological seed dormancy mechanism. Keywords: Banana; germination; true seed; viability; vigor

Abstract

Corn (Zea mays) is a vital staple crop and the second-largest agricultural commodity in Indonesia. However, productivity remains suboptimal, often due to nutrient imbalances, particularly in phosphate-rich soils where availability to plants is limited. This study aimed to assess the effects of reducing phosphate fertilizer by 50% in combination with bioagents Trichoderma harzianum, Metarhizium anisopliae, and arbuscular mycorrhizal fungi on key agronomic traits of corn. A randomized block design was employed to measure parameters including root volume, root-to-shoot ratio, leaf width, and seed sphericity. Results showed that applying 50% phosphate fertilizer alone yielded the highest root volume (70.00±18.19 mL) and root-to-shoot ratio (0.50±0.32), suggesting improved root development. In contrast, treatment with Metarhizium produced the widest leaves (10.14±0.30 cm) but showed the lowest values for root volume and root-to-shoot ratio. These findings highlight the potential of combining moderate phosphate input with beneficial bioagents to improve corn performance in marginal soils. The approach offers a cost-effective and environmentally sustainable alternative for managing nutrient imbalances. Further studies on long-term effects and economic feasibility are recommended to support wider adoption of these practices in sustainable agriculture.

Abstract

Jack bean or koro pedang is a potential source as a soybean substitute for food and feed. In production, the plant is also useful in crop rotation and intercropping to support sustainable agriculture systems. However, jack bean production in Indonesia is still challenging. One of the obstacles in the production is the flowers and pods dropping, which reduces yield markedly. This study aimed to evaluate the source and timing of additional potassium fertilizer on the generative phase and yield of jack bean. The experimental design used a randomized complete block design with two factors, i.e., the source of potassium fertilizer as the first factor consisting of five levels: no fertilizer application, base fertilizer, base fertilizer + goat manure, base fertilizer + rice husk ash, and base fertilizer + KCl. The second factor was fertilization time, i.e., at 46 and 121 days after planting. The treatment of the potassium fertilizer source and fertilization timing affected several generative characters, but did not have much effect on productivity. Future studies should identify other potassium fertilizer sources to find the optimal dose to support plants in the generative phase. Keywords: additional potassium; flower drop; koro pedang; pod formation

Abstract

Plant growth-promoting rhizobacteria (PGPR) and frass application have drawn interest as ways to increase plant productivity. This research aimed to evaluate the effect of frass and PGPR application on the growth and yield of kailan. The effects of varying frass dosages/F (0, 15, 20, and 25 tons ha-1) and PGPR concentrations/P (0, 5, and 12.5 mL L-1) on plant height, leaf number, leaf area, scaffold weight, and leaf weight per plant at 14, 21, and 28 days after planting (DAP) were examined. The growth of plants was generally enhanced by increasing dosages of frass and PGPR. The treatment F25P5 consistently produced the best results across all parameters, demonstrating its effectiveness in enhancing plant growth and yield. Positive correlations between plant height, leaf area, and leaf weight per plant (0.99) were found using correlation analysis, suggesting that leaf expansion is essential for biomass accumulation. Plant height, leaf number, and biomass-related parameters clustered together, confirming their interdependence in growth, and principal component analysis (PCA) showed that PC1 explained 94.09% of the variance. The results highlight that while excessive doses of frass and PGPR may have declining effects, balanced treatments significantly increase plant productivity. Optimizing the dosage of Frass and Rhizobia is crucial to achieving the best results for Brassica oleracea. Frass 25 tons ha-1 and PGPR 5 mL L-1 appear to be the most effective treatment. Keywords: biofertilization; ecofriendly fertilization; Rhizobacteria
