Abstract

Eggplant cultivation displays versatility across various soil types. However, nutrient depletion, a result of excessive chemical fertilizer utilization, presents a growing concern. The integration of green manure into agricultural practices, catering to diverse soil types, can remediate this nutrient loss. The purpose of this study was to investigate eggplant growth and yield responses to differing green manure quantities across varying soil types. Employing a factorial experimental method, this research was structured in a completely randomized design (CRD). Two independent variables were evaluated: green manure dosage, with three levels (30 g/plant (D1), 60 g/plant (D2), 90 g/plant (D3)), and soil type, also classified into three categories: Latosol (T1), Grumusol (T2), and Regosol (T3). Data interpretation was conducted using analysis of variance, followed by the Tukey test, each executed at α = 5% significance level. Outcomes indicated a notable interaction between green manure dosage and soil type concerning the leaf area and root fresh weight parameters. The optimal combination emerged as a 30 g/plant green manure dosage applied to Regosol soil type. Notably, individual treatments exerted divergent effects on eggplant growth parameters, though no significant impact on eggplant yield parameters was observed. This research underscores the interplay between green manure usage and soil type in cultivating eggplants, adding value to sustainable agricultural practices.

Abstract

Oil palm (Elaeis guineensis Jacq) is a crucial plant for Indonesia's economy, serving as a major non-oil foreign exchange earner. A significant pest affecting oil palm cultivation, especially during replanting, is the rhinoceros beetle (Oryctes rhinoceros L.). Attractant pheromones, derived from pineapples, contain volatile compounds that attract insects. This research aims to develop an automated rhinoceros beetle trap equipped with an automatic pheromone spray system utilizing natural peel pineapple extract. The analysis includes tests for fluid density, spray distribution, and normality. The fluid density of the sample closely resembles that of water (1 g/cm³). Spray distribution results indicate particle sizes (60-112 μm) larger than airborne aerosols (0.001-50 μm). Kolmogorov-Smirnov normality tests reveal mostly normal data distribution, with minor deviations. Overall, this trap exhibits promise as an effective solution for rhinoceros beetle control in oil palm cultivation.

Abstract

Anthracnose, a primary disease in chili plants caused by the pathogen fungus Colletotrichum sp., has proven significant losses by affecting harvests and inducing fruit decay. Control measures using synthetic pesticides have been implemented but yielded unsatisfactory results. The utilization of resistant varieties stands as a pertinent approach in early control efforts to minimize harvest losses. Additionally, the use of resistant varieties is a crucial component of integrated disease control implementation. This study aims to investigate the resistance levels of ten chili varieties commonly grown in swampy areas against specific isolates of Colletotrichum sp. present in swampy locations. The research, conducted in a randomized complete design in a greenhouse, tested ten varieties of cayenne pepper typically cultivated in swampy areas. The results revealed that the Hiyung variety is Susceptible, while Bara, Dewata 43 F1, Tiung Tanjung, Genie, Sekar, and CR-9 varieties exhibit moderate resistance. Conversely, Tiung Ulin, Alip, and Sret varieties are classified as resistant. The incubation period for tested cayenne pepper varieties varied, ranging from 3.5 to 5.3 days. A longer incubation period indicates greater resistance to anthracnose in chili varieties. The selection of resistant varieties is a pivotal step in anthracnose management, not only to minimize harvest losses but also to support an effective integrated control approach.

Abstract

Avocado is a much-loved fruit with high nutritional content. However, its current production has declined due to excessive and continuous use of chemical fertilizers. Biofertilizers can be applied to reduce the reliance on chemical fertilizers, promoting soil health and fertility by providing essential macro and micronutrients for better plant growth. This study aimed to determine the optimal dosage and method for the combined application of biofertilizer, biosurfactant diethanolamide (DEA) palm olein, and neem extract on avocado seedlings. The experimental design used was a factorial randomized complete block design with two factors. The first factor was the biofertilizer dosage (B) and the second factor was the application method (M). Results indicate that a 10 mL/L biofertilizer dosage, 5% DEA, and 35% neem extract show the best effects on plant height, leaf chlorophyll levels, stem diameter, and the number of avocado leaves. The application method of applying to the planting medium yields the best results for plant height, leaf count, and leaf chlorophyll levels. There was an interaction between treatments regarding plant height at 10 weeks after transplanting (WAT) and leaf count at 8 WAT. Biofertilizer application by pouring is recommended as an alternative to inorganic fertilizers for promoting healthy avocado seedling growth.

Abstract

Grammatophyllum stapeliiflorum, recognized as the melancholic orchid, represents one of the elusive orchid species facing the brink of extinction, thus exacerbating its rarity. Tissue culture technology becomes imperative for the propagation of this orchid species. This study aims to scrutinize the influence of different concentrations of the synthetic growth regulator thidiazuron (TDZ) on distinct basal media types, Murashige Skoog (MS) and Vacin and Went (VW), on the in vitro growth of G. stapeliiflorum orchids. Employing a complete randomized factorial design, the study entails two research factors: TDZ concentration with 4 treatment levels, A0 = 0 mg/L, A1 = 0.25 mg/L, A2 = 0.50 mg/L, and A3 = 0.75 mg/L, and the second factor being the media type, B1 = ½ MS and B2 = ½ VW. Findings indicate significant effects of MS and VW media on the percentage of viable explants, browning, globular forms, and shoots. Interaction between TDZ concentration and media type didn't yield significant effects on each experimental parameter. Treatment with 0.25 and 0.50 mg/L TDZ on ½ VW media demonstrated optimal results for explant growth percentage, browning, and explants in the globular phase, at 97.33%, 2.67%, and 2.67%, respectively. Moreover, treatment with 0.75 mg/L TDZ on ½ VW media resulted in the highest percentage of explant coloration. The combination of TDZ and media has shown the potential to enhance the production efficiency and conservation of this rare orchid species through tissue culture technology.

Abstract

Composting serves as a pivotal strategy in waste management, alleviating the burden on final disposal sites while simultaneously providing valuable fertilizer for urban agriculture. This study aims to delineate the intricacies of the composting process and elucidate the characteristics of compost derived from recycling centers/compost houses in Surabaya City, Indonesia. Employing a qualitative descriptive approach, this research scrutinized the composting process by delving into the origins of raw materials, procedural stages, and the chemical composition of the resultant compost. The composting materials encompassed household waste, market refuse, and fall foliage. Notably, composting occurred within an open aerobic system devoid of bio-activators. Chemical analysis revealed: C/N ratio (17.10 - 19.60), C-total (17.65% - 18.10%), N-total (0.95% - 1.12%), P2O5 (0.35% - 0.51%), K2O (0.39% - 0.41%), Cu (1.65 ppm - 2.01 ppm), Pb (2.05 ppm - 3.11 ppm), Cd (0.11 ppm - 0.24 ppm), and Zn (1.02 ppm - 1.14 ppm). Physically, the compost manifested as a dark brown substance, exhibiting a soil-like softness attributable to grinding, with temperatures oscillating between 41.90 to 55.00°C. Visually, the compost appeared mature and primed for utilization based on color and texture criteria; however, indicators such as C/N ratio and temperature suggest an immature state rendering the compost unsuitable for immediate planting. To ensure optimal maturity conducive to plant growth, it is recommended that users store the compost for a minimum of one month before application, thereby fostering its maturation process.

Abstract

Chili pepper, tomato, and squash cultivated in Magelang Regency, Central Java Province, Indonesia showed severe viral symptoms. Three samples were taken then molecularly tested against begomovirus, potyvirus, tobamovirus, and polerovirus. However, PCR test confirmed only begomovirus infections. BLAST analysis concluded that the chili pepper and tomato isolates were pepper yellow leaf curl Indonesia virus (PepYLCIV) while the squash isolate was squash leaf curl China virus (SLCCNV). The 552 bp partial AV1 gene sequences of the three isolates were given NCBI GenBank acc nos. OR924278-80. PepYLCIV OR924279 and OR924280 formed a subgroup with LC542629 from Bali in the phylogenetic tree constructed using MEGA11, and shared 95.8 – 96.7% identities at nucleotide (nt) and 98.4 – 99.5% at amino acid (aa) levels according to Sequence Demarcation Tool v1.2 software. Meanwhile, SLCCNV OR924278 was clustered, and shared 95.8 – 96.7% nt and 98.4 – 99.5% aa identities with three Malaysian isolates (MW248685, MW248687, and MW248689). Different plant species inoculated with SLCCNV OR924278 remained symptomless up to four weeks observation, suggesting that the isolate is not mechanically transmissible. This study contributed additional knowledge on molecular variation while expanding hosts and distribution of PepYLCIV and SLCCNV in Central Java Province.
