Abstract

Shallot is an important horticultural commodity. Shallotproduction is influenced by variety, planting material, environment,growing media, and nutrient availability. Optimal sunlight intensityand appropriate nutrient types are essential to achieve high yields.Adequate nutrients can be obtained through the application ofanimal manure to the growing media. This study aimed to determinethe effect of shading and types of animal manure on the yield ofLokananta shallot variety from True Shallot Seed (TSS) grown inUltisol soil. The research was conducted on Ultisol soil inPangkalpinang City, Bangka Belitung Islands Province, from April toSeptember 2024. A split-plot design arranged in a RandomizedComplete Block Design (RCBD) was used. The main plot was shadingtreatment (with shading and without shading), and the subplot wastypes of animal manure (chicken, cattle, goat, swiftlet, and batmanure). Data were analyzed using Fisher's test and the HonestlySignificant Difference (HSD) test at a 95% confidence level. Theresults showed that the treatment without shading produced the bestagronomic characteristics of TSS-grown shallots in terms of numberof leaves, number of tillers, stem diameter, and number of bulbsacross different animal manure types in Ultisol soil. The combinationof chicken manure and no shading yielded the best plantcharacteristics in terms of number of leaves, number of tillers, freshweight, and dry weight in Ultisol soil. The application of chickenmanure showed superior performance in number of tillers, stemdiameter, and fresh weight.

Abstract

Land use conversion in the hilly area of Wonosalam, Jombang Regency, has significantly altered vegetation cover, leading to increased soil erosion rates. This study aims to analyze soil erosion magnitude across various land use types and assess the impact of land conversion on erosion levels in Wonosalam Village in 2014, 2019, and 2024. A quantitative approach was applied using the Universal Soil Loss Equation (USLE) model combined with spatial analysis through Geographic Information System (GIS). Data sources include Landsat 8 imagery, land use maps, rainfall data, slope maps, and laboratory analysis of soil physical and chemical properties. Each erosion factor (R, K, LS, C, and P) was analyzed to estimate soil loss (A) in tons/ha/year. The results indicate that the conversion of forest areas into agricultural and residential lands significantly increases erosion rates, especially on slopes steeper than 25%. Conversely, forested areas with dense vegetation show the lowest erosion rates. These findings demonstrate a strong correlation between land use change and erosion acceleration. The study provides valuable insights for soil conservation planning and sustainable land management in the hilly regions of Wonosalam

Abstract

Avocado cultivation in Indonesia shows strong potential due to increasing national production. Vegetative propagation using grafting techniques is key method for improving plant quality. Following grafting, seedlings must be transplanted into a new planting medium that supports optimal growth. Planting media composed of topsoil, raw husks, and manure as along with the application of Liquid Organic Fertilizer (LOF) derived from goat biophosphate, are crucial for seedling development. This study investigated the effects of planting medium composition and goat biophosphate LOF concentration on the growth of grafted ‘Alligator’ avocado seedlings. The study was conducted at the Wire House of Jember State Polytechnic from August to October 2023 using two-factor Randomized Block Design (RBD). The factorcs were (1) planting medium composition (P1 = 2:1:1, P2 = 3:1:2, P3 = 2:1:2) and (2) LOF concentration (K1 = 2 ml/L, K2 = 4 ml/L, K3 = 5 ml/L). Data analysis using ANOVA and DMRT at 5% and 1% significance levels, respectively, showed that the planting medium significantly affected the number of leaves (P1 was the most effective). The concentration of LOF significantly affected stem diameter (K3 was the most effective), and the interaction between the two factors significantly influenced plant height and number of leaves at 12 weeks after planting.

Abstract

Rice is the primary staple food for most of the Indonesian population. Seed deterioration during storage reduces germination ability and threatens rice production. Seed invigoration through priming can restore seed quality by activating pre-germinative metabolism before radicle emergence. This study aimed to determine the best combination of organic priming using noni fruit extract and soaking period on the invigoration of expired local rice seeds. The research used a Completely Randomized Design (CRD) factorial experiment with a separate control was used, comprising 12 treatment combinations each repeated three times (39 experimental units). The first factor was the concentration of noni fruit extract (M) with four levels (0%, 1.5%, 3%, and 4.5%), and the second factor was the soaking period with three levels (12, 24, and 48 hours). Seeds were germinated using the UKDdp method with 50 seeds per roll. Organic priming with noni fruit extract combined with a soaking period significantly improved all measured germination parameters, including maximum growth potential, simultaneity of growth, germination capacity, vigor index, and growth speed of the deteriorated local rice seeds (variety Buyung Banjar). The best treatment combination was 4.5% noni fruit extract with a 24-hour soaking period (M3T2), which increased germination capacity by 1.6-fold and vigor index by 2.13-fold compared to the untreated control.

Abstract

Oil palm seedling growth is highly affected by the planting media. The planting media commonly used in oil palm nurseries are derived from subsoil, which has low fertility levels and therefore requires improvement through the addition of organic fertilizers. The application of compost and chicken manure has been shown to enhance the growth of oil palm plants by increasing macro and micronutrient availability, improving organic matter content, enhancing soil structure, and supporting microbial activity. This study aimed to determine the optimal planting medium combination for the growth of oil palm seedlings during the main nursery stage. The experiment was arranged in a Randomized Complete Block Design (RCBD) with five treatments, namely: P0 = control (subsoil), P1 = 2:1 (subsoil + compost), P2 = 1:1 (subsoil + compost), P3 = 2:1 (subsoil + chicken manure), and P4 = 1:1 (subsoil + chicken manure). Each treatment was replicated four times, and the observed parameters included plant height, number of leaves, stem diameter, leaf greenness, and c-organic. The observed data were analyzed using an F-test, followed by a Least Significant Difference (LSD) test at the 5% significance level. The results showed that the addition of compost or chicken manure to the subsoil planting medium improved the growth of oil palm seedlings at the main nursery stage. The P4 treatment (subsoil + chicken manure at a 1:1 ratio) significantly improved plant height, number of leaves, stem diameter, and leaf greenness of oil palm seedlings, and produced the highest organic carbon content among treatments.

Abstract

Black soybean (Glycine max (L.) Merr.) is an important source of bioactive compounds, particularly anthocyanins and flavonoids, which contribute to seed nutritional quality. This study evaluated the effects of boron (B) and liquid biofertilizer (LBF) application on flavonoid, anthocyanin, and total protein contents in black soybean seeds. The experiment was conducted in Batu, East Java, Indonesia (739 m above sea level) from May to October 2025 using a randomized block design with three replications. Six treatment combinations were applied: B 2.5 kg ha⁻¹ + LBF 10 mL L⁻¹ (P1), B 2.5 kg ha⁻¹ + LBF 15 mL L⁻¹ (P2), B 5 kg ha⁻¹ + LBF 10 mL L⁻¹ (P3), B 5 kg ha⁻¹ + LBF 15 mL L⁻¹ (P4), B 7.5 kg ha⁻¹ + LBF 10 mL L⁻¹ (P5), and B 7.5 kg ha⁻¹ + LBF 15 mL L⁻¹ (P6). The combination treatment significantly affected flavonoid, anthocyanin, and protein contents. The highest flavonoid and anthocyanin contents were obtained under P5, whereas the highest protein content was recorded under P6. These findings indicate that boron and liquid biofertilizer application can influence the biochemical composition of black soybean seeds, with different treatment combinations favoring the accumulation of secondary metabolites and protein.

Abstract

Rice (Oryza sativa L.) is a major global agricultural commodity and plays a crucial role in food security, especially in Asia. The decreasing presence of local rice varieties highlights the need for conservation through identification and evaluation, as they represent valuable genetic resources for the development of superior cultivars. This study aimed to analyze differences in seed morphology, seed quality, and seedling growth among several local rice genotypes. A Completely Randomized Design (CRD) with one factor was used, involving four genotypes: Sedayu, HMS 700, Tri Sultan 05, and a control variety, Situbagendit. Each treatment was replicated six times, totaling 24 experimental units. The study was conducted in three stages: seed morphological characterization, seed quality testing, and field evaluation at the vegetative phase. Observed seed traits included grain length, width, color, presence of trichomes on lemma and palea, tip hair color, and rice color. Seed quality parameters included moisture content, purity, 1,000-grain weight, germination rate, vigor index, maximum growth potential (MGP), and growth speed index (GSI). Field observations included leaf color, plant height, and fresh and dry seedling weight. Data were analyzed using ANOVA at the 5% level, followed by Duncan’s Multiple Range Test (DMRT). The results indicated significant differences in seed morphological traits among genotypes, particularly in grain color, rice color, length, and width. The Tri Sultan 05 genotype demonstrated superior performance in germination rate, vigor index, MGP, plant height, and both fresh and dry biomass.

Abstract

Peronosclerospora spp. are pathogens causing powdery mildew disease in corn. The increasing number of corn varieties available in the market leads to fluctuations in powdery mildew levels in corn production centres. This study aims to improve the resistance of several corn varieties to powdery mildew by examining stomatal and trichome function and identifying the pathogens involved. This study was conducted in Morosunggingan Village, Peterongan District, Jombang Regency, in October-November 2025, and involved the observation of 0.5 ha of corn plants. Sampling was carried out every 4 days for each variety, starting 4-26 days after planting. The observed parameters analysed included disease incidence, disease severity, AUDPC value, stomatal and trichome density, and the pathogen causing powdery mildew. The conclusions that can be put forward are: 1) Andalan NK007 and Pioneer P40 varieties are more resistant to powdery mildew disease attacks than Berlian 415 varieties. 2) Lower stomatal density and higher trichomes contribute positively to the level of resistance to powdery mildew disease attacks. 3) The powdery mildew disease attack in Morosunggingan Village, Peterongan District, Jombang Regency, was caused by the fungal pathogen Peronosclerospora

Abstract

A combination of Diluted Sea Water (DSW) and Aerated Compost Tea (ACT), as a nutrient source, may increase yield of Pak Choi (Brassica rapa L.). The study investigating  the interaction effects of DSW and ACT on growth and yield of Pak Choi was conducted at the greenhouse of Trunodjoyo University Madura from December 2022 – January 2023. This factorial experiment was arranged on a completely randomized design with two factors. The DSW factor consisted of two levels: S0 (0% ) and S1 (3,0%). The ACT factor contained three levels: P0 (0%), P1 (6,0%), and P2 (12,0%). The combination resulted in six treatments: S0P0 (Control), S0P1 (6% ACT), S0P2  (12% ACT), S1P0 (3% DSW), S1P1 (3% DSW + 6% ACT), and S1P2 (3% DSW + 12% ACT). Each treatment was replicated for four times, totaling 24 experimental units. Data were analyzed using ANOVA (p 0.05) and mean differences were analyzed by DMRT (p 0.05). Results showed that interaction of DSW and ACT significantly increased plant height, leaf number, leaf area, fresh  and dry weight, and chlorophyll content with the S1P2 treatment yielding the best result. Plant yield and chlorophyll content under S1P2 was respectively 25% and 19% higher than the control. Effects of higher concentration of  DSW and ACT on plant growth and yield as well as the changes of soil characteristics warrant for further study.

Abstract

Sorghum is a cereal crop that is tolerant to dry conditions, making it potentially suitable for cultivation in drylands in Madura. This study aimed to describe seed morphological characteristics and early imbibition dynamics, and to evaluate the relationship between these two characteristics in three local Madura sorghums. The observed seed morphological characteristics included color, length, width, and thousand-seed weight, while the percentage of water absorption determined imbibition dynamics during the first 1–4 hours. The data were analyzed descriptively, followed by Pearson's correlation analysis and principal component analysis (PCA). Descriptive analysis revealed variation in seed morphological traits and early imbibition patterns among the three local Madura sorghum accessions. SPG2 showed a rapid early imbibition pattern, SPG1 exhibited a gradual increase in water uptake, whereas BKL displayed slow initial imbibition followed by a steady increase throughout the observation period. Positive correlations were observed among seed morphological traits, whereas negative correlations were found between seed morphological traits and early imbibition during the first three hours (IMB1–IMB3). PCA analysis showed that imbibition dynamics and thousand-seed weight were the traits that contributed the most to data diversity (PC1 = 71.4%). The results of this study provide basic information for characterizing local Madura sorghum germplasm.
