Potential of Scallion Population (Allium fistulosum L.) in Intercropping Pattern with Katokkon Chili and Poc Type in Increasing Productivity
Full text linkThis study aims to determine the effect of the spring onion (Allium fistulosum L.) population in an intercropping pattern with Katokkon chilli (Capsicum annuum L. var. sinensis) and the type of Plant Organic Compost (POC) on plant productivity. The research was conducted from February to September 2024 in Lilikira Village, Nanggala District, North Toraja Regency. A two-factor factorial design was arranged in a randomized block design (RBD). The first factor was the intercropping planting pattern, which consisted of three levels: TS1 (Katokkon intercropped with one row of spring onions), TS2 (Katokkon intercropped with two rows of spring onions), and TS3 (Katokkon intercropped with three rows of spring onions). The second factor was the type of POC, which included three levels: P0 (control), P1 (banana tuber POC), and P2 (krokot POC). The results showed that the intercropping pattern of spring onions with a population of 20 spring onions per plot with Katokkon chili combined with the type of banana tuber POC had a significant effect on the variables of Katokkon chili, namely flowering age, number of productive branches, number of fruits per plant, number of fruits per plot, fruit weight per plant and fruit weight per plot. The intercropping pattern of spring onions with a population of 20 spring onions per plot with Katokkon chili combined with the type of banana tuber POC had a significant effect on the variables of spring onions, namely the number of leaves at 8 weeks after planting, the number of shoots, weight per clump and weight of clump per plot
The Effectiveness of Planting based on The Number of Seeds in Increasing The Adaptability and Productivity of Sweet Corn
Full text linkThis study aimed to evaluate the influence of the number of seeds per planting hole on the productivity and adaptability of sweet corn varieties. Using a nested research design, eight Indonesian commercial sweetcorn varieties were tested with variations in the number of seeds per planting hole. Results showed that plant height ranged from 144.86 cm to 191.66 cm, with the BN 44 variety having the highest height. However, seed number treatment did not significantly affect plant height, stem diameter, or leaf count. Meanwhile, the highest productivity is achieved by the Talenta and Bonanza 9 F1 varieties at the treatment of one seed per hole, as well as the Prima variety at the treatment of two seeds. These findings emphasize the importance of variety selection in the management of sweet corn cultivation and show that although seed numbers are insignificant, the right variety can improve crop yields. The implications of this research are important for the development of sustainable and efficient agricultural strategies and can contribute to food security through increased sweet corn productivity
Evaluate The Effect of Different Concentrations of Gibberelin (GA3) on The Gemination and Early Seedling Growth of F1 Hybird Cucumber Cucumis sativus in Malaysia
Full text linkConditions and factors that can influence the development of cucumber cultivation in Malaysia are climate and soil because Malaysia has a warm and humid climate, ideal for growing cucumbers. Farmers' cultivation methods often use hydroponic techniques and planting systems in open fields. Providing gibberellin to cucumber plants can be a solution to overcome several problems that cause suboptimal production. Objective: This study aims to evaluate the effect of different concentrations of gibberellin (GA3) on the germination and initial growth of F1 hybrid cucumber seeds. This research method was prepared in a Non-Factoral Completely Randomized Design (CRD) in 4 replications which were repeated once. The first factor is without concentration (control), (200 ppm), (500 ppm), (800 ppm). The gibberellin concentration can significantly influence all cucumber growth parameters, except for the root length of cucumber plants. The best treatment is P3 (500 ppm)
Morphological Characteristics of Leaf Color and Leaf Shape of Soybean Variety Anjasmoro (Glycine max (L.) Merril) under Water Stress
Full text linkAnjasmoro soybean variety exhibits intolerance to water stress, which can significantly impact the growth of soybean plants, particularly concerning leaf morphological characteristics. This study aims to assess the effects of water stress on the leaf color and leaf shape of the Anjasmoro soybean variety. The research was conducted from June to July 2024 at the Gauze House of Food Crop Agribusiness at SMKN 1 Tambusai, Rokan Hulu, and the Integrated Laboratory of the Agrotechnology Study Program at the Faculty of Agriculture, Pasir Pengaraian University. The materials utilized in this study included Anjasmoro soybean seeds, soil, 35 x 40 cm polybags, and 15 kg of goat manure. This investigation employed a Non-Factorial, Completely Randomized Design (CRD), focusing on the variable of water stress (P) with three replications. The water stress treatments consisted of four levels: P0: 25% field capacity (KL) water stress applied twice daily, P1: 25% KL water stress applied twice daily, P2: 25% KL water stress applied once every three days, and P3: 25% KL water stress applied once every six days. The results indicated that water stress did not significantly affect the leaf color and leaf shape of the Anjasmoro soybean variety in the P0, P1, and P2 treatments. However, the P3 treatment resulted in observable leaf color and shape changes. These findings suggest that the Anjasmoro soybean variety has a low drought tolerance
Morphological Characteristics and Evaluating Bioactive Compound Extracts of Isotoma longiflora and Clitoria ternatea Plants from Central Kalimantan as Therapeutic Agents
Full text linkCentral Kalimantan is characterized by its diverse biological resources, including traditional medicinal plants such as Isotoma longiflora (known as kitolod) and Clitoria ternatea (often called blue pea flower). This research aims to investigate the therapeutic properties of extracts derived from these two plants while also evaluating their efficacy and safety within the public health framework in Central Kalimantan. The study focused on the bioactive compound extracts from Isotoma Longiflora and Clitoria ternatea, both sourced from this region. These plants are recognized for their secondary metabolites, including flavonoids, saponins, tannins, and alkaloids, which offer various pharmacological advantages. Employing exploratory survey techniques alongside laboratory experiments, the research examined the plants’ morphological characteristics and assessed their extracts’ effectiveness on mice infected with Fusarium sp. Findings indicated that the combined extracts significantly lowered the intraocular pressure (IOP) in the infected mice, reducing it from 25.375–33.25 mmHg to nearly normal levels, precisely 12.075–14.575 mmHg. This observed efficacy is attributed to the bioactive compounds’ antioxidant, antimicrobial, and anti-inflammatory properties. The study underscores the potential of Isotoma Longiflora and Clitoria ternatea from Central Kalimantan as viable local plant-based therapeutic agents, thereby contributing to the advancement of herbal medicine and the conservation of biodiversity
Effectiveness of Corn (Zea mays ssp L. var. Saccharata) Seed Harvesting Speed Using a Mini Combine Harvester in Corn Seed Production
Full text linkMalaysia's animal feed production exceeds demand, accounting for about 45-65% of the composition of most feed products. In Malaysia, grain corn imports increased from approximately 2.5 million tonnes in 2000 to 4.0 million tonnes in 2019 for use as animal feed. This experiment was conducted at MARDI Seberang Perai, Penang, from June 2018 to the end of February 2020, using a Worldstar 7.0 PLUS (WS7.0PLUS) mini combine harvester. The basic operation of this mini combine harvester is similar to the Kubota mini combine harvester, which is widely used for paddy and grain corn harvesting. During the harvesting process, three methods were employed to test the speed of the mini combine harvester. Although this harvester is capable of harvesting four rows at once, considerations about potential plant losses necessitated harvesting only three rows for the purposes of this study. The harvester’s speed directly affected the loss rate and work efficiency, depending on the soil surface conditions in the test plot. Harvesting losses were categorized into two types: losses on the cutting table and losses during seed separation. Losses on the cutting table occurred in front of the harvester during the cutting process and were measured by collecting plants left in each row after the harvester passed. Losses during separation occurred when plant seeds fell behind the machine during the separation process, and these were measured by collecting samples using a 2 m x 2 m PVC quadrant placed behind the machine. The total losses due to the cutting table and separation system during harvesting using the mini combine harvester ranged from 2.45% to 6.43%. Each harvester speed produced varying results, significantly affecting the overall loss rate and efficiency of the operation

The population of each stage of development of Brontispa longissima varies with the average population of larval development being 43.68% followed by pupae 24.24%, imago 16.17% and the lowest population namely eggs 15.91%, with the natural enemy found being the pupal parasitoid Tetrastichus brontispae (Hymenoptera: Eulophidae), the entomopathogenic fungus Metarhizium anisopliae, and predators cocopet Celisoches morio (Dermaptera: Celisochidae). The most common natural enemy found is the cocopet C morio
Effectiveness of Bacterial Consortium and Biochar in Remediation of Heavy Metals in Polluted Soil
Full text linkThe remediation of heavy metal-contaminated soil is a crucial step in environmental recovery. This study evaluated the effectiveness of bacteria and biochar in reducing lead (Pb) and copper (Cu) contamination in agricultural soil surrounding the Medan Industrial Area. A Factorial Randomized Block Design (RBD) was employed, incorporating two factors: bacteria (Corynebacterium glutamicum and Lactobacillus sp.) at three levels (0 g, 5 g, and 10 g per plant) and biochar application at three levels (0 g, 10 g, and 20 g per plant), using mustard greens (Brassica juncea) as the indicator plant. The observation parameters included biomass and Pb and Cu content in both soil and plant tissue. Data analysis was conducted using ANOVA and the Honestly Significant Difference Test (HSD) at the 5% significance level The results indicated that bacterial treatment at a level of 5 g per plant and biochar at 20 g per plant significantly increased the wet weight per plant, the wet weight per plot, and the wet weight of plant roots when biochar was administered. The concentrations of the heavy metals lead (Pb) and copper (Cu) in soil and plants decreased with increasing levels of bacteria and biochar. The average reduction in Pb in soil and plants due to bacterial treatment was 1.28% and 0.29%, respectively, while the average decrease in Cu content in soil and plants was 1.03% and 0.17%. Biochar treatment reduced Pb in soil and plants by 0.44% and 0.07%, respectively, and Cu by 0.34% and 0.08%. This study demonstrates that bacteria and biochar stabilize heavy metals in contaminated soil

Evaluation of Tolerance of Several Corn Genotypes (Zea mays L.) to Salinity Stress at the Germination Stage
Full text linkCorn (Zea mays L.) is a vital food crop with the potential to enhance food supply and support other sectors, such as livestock production. This study aims to determine the level of salinity stress that can be utilized to select maize genotypes tolerant to such stress. The research was conducted in the greenhouse of the Maros Cereal Research Center (Balitsereal) starting in February. The experimental design employed a split-plot arrangement consisting of two factors. The main plot consisted of five levels of NaCl concentration: no salinity stress and concentrations of 30, 60, 90, and 120 mM. The subplot included eight maize genotypes. Each treatment combination was replicated three times. Corn seeds were germinated for five days in petri dishes lined with germination paper, with ten seeds per dish. Afterward, the seeds were treated with NaCl and distilled water. The germinated seeds (after 5 days) were then transferred to the next germination medium, specifically styrofoam. At the germination stage, the tolerance selection of several corn genotypes under salinity stress revealed that NaCl concentration significantly affected plumule length, root length, and the number of roots. As the NaCl concentration increased, plumule length, root length, and the number of roots decreased. Additionally, genotype significantly impacted root length, the number of roots, and the percentage of seed growth. The results of the variance analysis indicated that there was no interaction between NaCl concentration and genotype at the germination stage
