Abstract

Improvement of Ultisol soil chemical properties can be done by adding organic matter. In this study, vermicompost was used from various animal wastes (chickens, goats and cows), and the optimal growth parameters and nutrient uptake were observed. Research results showed The chicken manure vermicompost had the maximum available P, the goat manure vermicompost had the highest available K, and cow manure vermicompost had the highest total N value. In terms of pH, goat manure vermicompost had the highest pH and the chicken manure vermicompost had the most excellent C/N ratio. Analysis of variance (Anova) showed that the type and dosage of vermicompost had a significant effect on growth parameters (plant height, number of leaves and stem width) and nutrient uptake of N, P and K

Abstract

Entisols, comprising approximately 10.6% of Indonesia's land area, are youthful soils distinguished by sandy texture, loose structure, ample aeration porosity, rapid permeability, low water retention, and diminished organic matter. This study determines the optimal dosages of liquid organic fertilizer and cow manure capable of enhancing the physical attributes of Entisols and the growth and yield of sweet corn plants. Employing a Randomized Complete Block Design (RCBD) with two factors, the research evaluates three doses of cow manure (0 tons ha-1, 5 tons ha-1, and 10 tons ha-1) and four concentrations of liquid organic fertilizer (0 mL L-1, 100 mL L-1, 200 mL L-1, and 300 mL L-1). The findings reveal that liquid organic fertilizer significantly influenced soil wet weight and pF pressure at 0.1 atm (12.68 g-1). Application of cow manure demonstrates tangible improvements in Entisols properties, with water content at 12.15%, bulk density at 0.73 g m-3, permeability at 90.57 cm hour-1, and soil wet weight and pF pressure at 0.1 atm (15.10 g). Furthermore, liquid organic fertilizer contributes to a plant height of 176.82 cm and husk cob weight of 8,545 kg ha-1, while cow manure results in a plant height of 174.05 cm and husk cob weight of 8.044 kg ha-1. The optimal combination emerged with a 300 mL L-1 concentration of liquid organic fertilizer or a 10 tons ha-1 dose of cow manure,  showcasing superior enhancements in Entisols' physical properties, as well as sweet corn plant growth and yield.

Abstract

Cucumber is a popular vegetable that can be consumed fresh or processed into pickles, preserves, and other products. Efforts to enhance cucumber yield have been made through the application of Azolla compost and inorganic nitrogen (N) fertilizer. This study aimed to evaluate the interaction between different doses of Azolla compost and inorganic N fertilizer on cucumber growth and yield, as well as to determine the optimal doses of both fertilizers. The experiment was conducted from December 2021 to February 2022 in Medan Baru, Muara Bangkahulu District, Bengkulu City. A factorial randomized complete block design was employed with two factors: (1) Azolla compost doses (0 g plant-1, 90 g plant-1, 180 g plant-1, and 270 g plant-1) and (2) inorganic N fertilizer doses (0 g plant-1, 0.9 g plant-1, 1.7 g plant-1, and 2.5 g plant-1), resulting in 16 treatment combinations, each replicated three times. Data were analyzed using ANOVA at a 5% significance level, followed by Duncan’s Multiple Range Test for significant variables. Results indicated that there were no significant interaction effects between Azolla compost and inorganic N fertilizer on cucumber growth and yield. The 180 g plant-1 dose of Azolla compost produced the best results in terms of vine length, leaf number, fruit weight per plant, and plant dry weight. However, inorganic N fertilizer had no significant effect on cucumber growth and yield. Further research is needed to explore the effects of inorganic N fertilizer and the potential of Azolla as an environmentally friendly organic fertilizer in sustainable agricultural systems.

Abstract

Calamansi orange is a superior fruit that is being promoted for planting in Bengkulu Province. Calamansi citrus preparations have only a few variations, generally made into calamansi orange syrup. This research was conducted to make a new processed variation from calamansi orange juice to Nata de Citrus products and to optimize the nata fermentation medium based on glucose and nitrogen concentrations. This study used a factorial completely randomized design (CRD) with 2 factors. The first factor is the variation of glucose in the medium by diluting orange juice 0 times ( no diluting); 0.5 times; 1 times; 1.5 times and 2 times. The second factor is the variation of nitrogen in the medium obtained by adding 0.6% Ammonium Sulfate; 0.7% and 0.8%. The results were analyzed using ANOVA and for significantly different variables, further analyzed using orthogonal polynomial order 2. The optimum results were obtained at a glucose concentration of 1.76% (dilution of calamansi orange juice 1.65 times) and a nitrogen concentration of 0.17% (ammonium sulfate 0.8%).

Abstract

ABSTRACTFinding the appropriate method of fertilizer application to simultaneously enhance farm productivity and ensure ecosystem sustainability has been receiving a lot of attention. A field experiment was carried in the Research Plot Agriculture Faculty Bengkulu University Campus Indonesia in 2017. The purpose of this study was (1) to assess the significant effects of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC) under equal N conditions on growth, N accumulation, and yield of sweet corn, and (2) to determine the appropriate level to which inorganic N fertilizer could be reduced and equivalently replaced by bio-fortified compost to promote sweet corn growth and yield. The treatments consisted of six different proportions of inorganic N fertilizer (IF) substitution with bio-fortified compost (BC). Each treatment was designed on the basis of equal amount of total N input from a combination of both fertilizers (138 kg N ha-1).  They were arranged in a randomized block design with 3 replications. They included (1) 100% IF plus 0% BC, (2) 75% IF plus 25% BC, (3) 50% IF plus 50% BC, (4) 25% IF plus 75%, (5) 0% IF plus 100% BC, and (6) no IF and no BC. The results showed that the increasing proportion of IF replaced by BC resulted in an increase for all variables (except for plant height) but they decreased when 100% IF substitution with 100% BC was applied. Among the partial substitution treatments, 50% IF plus 50% BC consistently produced the best growth, N accumulation, and yield increase. Treatments of 50% IF plus 50% BC and 25% IF plus 75% BC produced the highest green cob weight with husk per plot (10.74 – 10.84 kg plot-1), which was 16% to 19% higher than treatment of 100% IF plus % BC. The three partial substitution treatments produced crop yield components as good as treatment of 100% IF plus 0% BC. Treatment of 0% IF plus 100% BC reduced plant growth, N accumulation, and crop yield and its components. The appropriate level to which IF could be reduced and equivalently replaced by BC was at the range of 25% to 75%. Hence, a suitable replacement of inorganic N fertilizer with bio-fortified compost is considered a reasoned way to simultaneously increase crop yield and reduce environmental degradation.Keywords: organic fertilizer, chemical fertilizer, bio-fortification, chemical fertilizer substitution, bio-fortified compost

Abstract

biodegradable polymer such as PVA is considered the most promising candidates for developing the sustainable sticker. The objective of this study was to determine the most suitable PVA + TS blends as adhesives agent for AMF spores inoculation via seed coating which can enhance the spores viability and their beneficial properties in maize. The polythene bag experiment was performed in a screen house of the Department of Plant Protection Faculty of Agriculture, University of Bengkulu Indonesia in 2015. Six adhesive blends were employed: 100% PVA + 0% TS, 75% PVA + 25% TS, 50% PVA + 50% TS, 25% PVA + 75% TS, 0% PVA + 100% TS, and no coating. The six experimental treatments were laid out in a completely randomized design with three replications. The results show that root colonization, AMF spore population, and shoot dry weight in 75% PVA + 25% TS were equal to those in 100% PVA. Root colonization, AMF spore population, shoot P content, and shoot P concentration were greater for 50% PVA + 50% TS than 100% PVA, 100% TS, and no coating. A mixture of 50% PVA + 50% TS was considered the preferred sticker. Thus, the tapioca starch can be used to substitute 25 - 50% of the PVA used without reducing AMF inoculant adhering to seed.Keywords: polymeric seed coating, seed coating formulation, arbuscular mycorrhizal fungi, sustainable coating adhesive, seed inoculation, seed inoculant

Abstract

[ENHANCING GROWTH AND YIELD OF SOYBEAN GROWN UNDER WATER-SATURATED CONDITIONS BY INORGANIC P AND EMPTY FRUIT BUNCH COMPOST AMENDMENTS IN ULTISOL]. The saturated soil culture practices with which to obtain high yield of soybean in Ultisol, characterized by high acidity, nutrient deficiencies and imbalances, should be  developed. This study was conducted to evaluate the beneficial effects of empty fruit bunch (EFB) compost combined with inorganic P application on growth and yield of soybean under water-saturated culture in Ultisol. This research was carried out from September to December 2022 in the rice field located in Kemumu Village, Arma Jaya District, North Bengkulu Regency, Bengkulu Province at an altitude of ±541 m above sea level. The field experiment was performed in factorial scheme based on a randomized complete block design with three replications. The experimental treatments included EFB compost as first factor at four levels (0, 5, 10, and 15 t/ha) and application of SP36 as second factor at four rates (0, 75, 150, and 225 kg/ha). Results show that Ultisol amended with a combination of 15 t/ha EFB compost and 75 kg/ha P2O5 resulted in the highest number of seeds per plant (about 142.266 seeds). The number of productive branches, fresh shoot weight, root dry weight, and root nodule weight was the highest in soil solely ammended with EFB compost at 15 t/ha. The sole P application at 225 kg/ha significantly (p<0.05) increased root dry weight and root nodule weight. Thus, under saturated soil culture, application of EFB compost and inorganic P in sole or combination would be the recommended nutrient management practice for enhancing soybean agronomic prformances in this acid soil.

Abstract

This research was conducted from July to November 2020 in the coastal lands of Ratu Agung District, Lempuing Village, Kuala Alam, Bengkulu City, at an elevation of 5 meters above sea level. The study aimed to investigate the interaction between vermicompost and single phosphorus (P) fertilizer on the growth and yield of Detam 4 soybean plants in coastal lands, focusing on determining the optimal doses for both inputs. The experiment was designed as a two-factor study using a factorial Randomized Complete Block Design (RCBD) with three replications. The first factor was vermicompost application at four levels: 0 tons ha-1, 5 tons ha-1, 10 tons ha-1, and 15 tons ha-1. The second factor was phosphorus application at three levels: 0 kg ha-1, 50 kg ha-1, and 100 kg ha-1. Observed variables included plant height, number of leaves, flowering age, number of productive branches, number of pods per plant, pod weight per plant, pod weight per plot, seed weight, and root weight. Data were analyzed using ANOVA at the 5% significance level, with a subsequent 5% LSD test if significant effects were found. The application of vermicompost at a dose of 10 tons ha-1 without the addition of single P fertilizer results in the best growth of the soybean variety Detam 4, characterized by the highest average shoot dry weight of 41.133 g, the fastest flowering age, and the greatest number of productive branches. The best yield of the Detam 4 soybean variety is achieved with the application of vermicompost at a dose of 15 tons ha-1, indicated by the highest number of productive branches and seed weight per plant. The independent application of single P fertilizer does not significantly enhance the growth and yield of the Detam 4 soybean variety in coastal land conditions.
