Abstract

Kale (Brassica oleracea var. sabellica) is a high-value vegetable that requires adequate lighting to support photosynthesis, especially when cultivated using a hydroponic system. This study aimed to examine the effect of LED lighting and reflector use on kale growth using the Deep Flow Technique (DFT). The research was conducted in September 2024 at the Horticultural Research Center, MARDI Serdang, Malaysia, using a Completely Randomized Design (CRD) with three treatments: 4 lamps (4L), 4 lamps with reflector (4 LMR), and 5 lamps (5L), each repeated five times for a total of 1,000 plants. Observed parameters included plant height, number of leaves, chlorophyll content, and Leaf Area Index (LAI). The results showed that the 4 LMR treatment produced the best growth, with the highest number of leaves, the highest chlorophyll content, and good LAI values. The use of reflectors effectively increased light absorption efficiency and photosynthesis. In contrast, the 4L treatment showed the lowest growth due to poor lighting and nutrient deficiencies. Overall, the MARDI reflector proved effective in enhancing kale growth in a DFT hydroponic system.

Abstract

Banyak penelitian telah dilakukan untuk mendeteksi jamur entomopatogen di dalam tanah menggunakan metode qPCR. Namun, beberapa penelitian menunjukkan bahwa metode qPCR belum mampu mendeteksi jamur di sampel tanah yang disebabkan oleh sedikitnya kemelimpahan jamur pada sampel tanah yang diuji. Untuk mengatasi masalah tersebut, pada penelitian ini dilakukan penambahan massa jamur target di dalam tanah pada tingkat tertentu melalui metode semi-kultur dengan tujuan untuk meningkatkan sensitivitas qPCR. Pertama, dipilih media selektif yang cocok untuk kultur keempat target jamur entomopatogen (Cordyceps militaris, Beauveria bassiana, Isaria fumosorosea, dan Metarhizium anisopliae). Kedua, dengan menggunakan media yang dikembangkan, hubungan antara unit pembentuk koloni (CFU) dan DNA tanah standar ditentukan. Ketiga, qPCR dilakukan terhadap ekstrak DNA yang diperoleh dari koloni jamur tiap level. Hasil menunjukkan bahwa media kultur tipe 3b menjadi media selektif yang terbaik untuk kultur jamur. Namun, hubungan linier dengan korelasi kuat antara suspensi jamur dengan nilai Ct belum dapat diperoleh sehingga metodologi semi-kultur tidak berhasil meningkatkan sensitivitas deteksi jamur entomopatogen dari sampel tanah menggunakan metode qPCR. Modifikasi ekstraksi DNA untuk meningkatkan kepadatan DNA dalam ekstrak perlu dilakukan untuk keberhasilan deteksi jamur entomopatogen.

Abstract

Productivity of green mustard (Brassica juncea L.) and pak choi (Brassica rapa L.) is often constrained by suboptimal cultivation practices. Sound-based stimulation, such as Sonic Bloom, offers a novel approach to enhance plant growth, yet comparative evidence across sound types remains limited. This study evaluated the effects of Qur’anic recitation and classical music on the growth and yield of both crops. A Randomized Block Design with a non-factorial time-series approach was implemented from July to September 2022. Two plant species (J1: green mustard; J2: pak choi) and three treatments were tested: S0 (control), S1 (Qur’anic recitation), and S2 (classical music). Sound exposure (90 dB, 20–14,500 Hz) was applied daily for 2 hours, beginning 7 days after planting and continuing until harvest (24 DAP). Growth parameters and biomass were analyzed using ANOVA and Tukey’s HSD (5%). Classical music (S2) significantly enhanced early growth, with plant height increases reaching 102.08% in green mustard and 91.16% in pak choi (6–12 DAP). Green mustard consistently outperformed pak choi across stages (77.88% vs 60.92% at 12–18 DAP; 42.07% vs 27.72% at 18–24 DAP). Leaf number increased up to 44.12%, and leaf area reached 208.74% under S2. Qur’anic recitation (S1) showed stronger effects at later stages, including higher dry root weight (0.34 g). Chlorophyll content was higher in green mustard but was not significantly affected by treatments. Classical music promotes early vegetative growth, while Qur’anic recitation supports sustained development. Sound-based stimulation represents a promising, sustainable strategy to enhance leafy vegetable productivity.

Abstract

Coconut (Cocos nucifera L.) is a multipurpose plant that has a very high level of cultivar diversity Almost all parts of the coconut plant, (Cocos nucifera L.) can be utilized and provide benefits for human life, In the fruit, from the skin to the coconut water, each has different functions and uses. This study aimed to determine the genetic diversity of selected coconut varieties. A total of 12 microsatellite markers were used to assess genetic diversity, 293 coconut individuals consisting of 19 coconut varieties, A total of 63 alleles were detected with an average of 5.25 alleles per locus. Polymorphic information content, (PIC) ranged from 0.1518 (C22) to 0.6778 (C2) with an average of 0.3546 per locus. Pairwise genetic distances ranged from 0.0361 (Malayan Red Dwarf-Malayan Green Dwarf) to 0.6585 (Malayan Yellow Dwarf-Rotuman). This value indicates a high similarity between the varieties Malayan Red Dwarf and MGD. The neighbor dendogram shows that the tall varieties Laguna, Rotuman, Markham, and Kar Kar are clustered together. Meanwhile, all dwarf varieties (MRD, MGD, MYD, Nias, Catigan, and CRD) are clustered together with the dwarf x dwarf hybrids Careca and Careni. These results provide important insights for future breeding activities and conservation management programs

Abstract

This study aims to determine the effect of biochar and microbial application on the growth and yield of sweet sorgum (Sorghum bicolor L.) in in seawater-intruded media. Biochar functions to improve soil structure and increase water retention and nutrient efficiency, while tobacco microbes have the potential to act as biological agents. The study employed a Split-Plot Design with two factors: biochar (0, 40, 80, 120 g/polybag) and microbes (0, 5, 10, 15 ml/polybag), each with three replications. Analysis results indicated that biochar application significantly influenced the parameters of seeds per panicle and seed weight per plot. The biochar treatment at a dose of 80 g/polybag produced the highest number of seeds per panicle at 74.54 seeds, while the treatment without biochar (B0) yielded the highest seed weight per plot at 57.65 g. The application of microorganisms and the interaction between biochar and microorganisms did not show a significant effect on all observed parameters. Biochar was proven effective in increasing sorghum yield on salt-intruded land through improved generative growth when applied at the optimal dose.

Abstract

Wheat is a cereal crop that can grow well in tropical areas only at high altitudes. However, the limited area of the highlands means that wheat development is directed at the lowlands, so plant breeding efforts are needed to obtain genotypes that are adaptive in the lowlands, one of which is through gamma ray irradiation. This research aims to identify the performance of agronomic characters of several wheat genotypes resulting from gamma irradiation planted in the lowlands. This study used a Randomized Block Design (RBD) with 2 factors, namely the first factor was wheat variety (Dewata/L, Basribey/I, and G-21/F) and the second factor was irradiation dose (0 Gy, 100 Gy, 200 Gy and 300 Gy). The data analyzed using F test at 5%. The treatment means were further compared and separated by using the Duncan Multiple Range Test (DMRT) at 5%. The research results showed that the wheat variety treatment had a significant effect on plant height and leaf area of wheat, while the gamma ray irradiation treatment and the combination of the two treatments had no significant effect on all parameters observed, but showed diversity in agronomic characters.

Abstract

Wheat is the largest cereal food in the world's staple food supply. The expansion of the wheat crop needs to be done through extensification efforts in the lowlands to increase domestic production. The main obstacles faced in the lowlands are the high air temperature and the intensity of sunlight. The research objective was to provide adaptive wheat mutant in the lowlands, especially in North Sumatra. The seeds of 3 varieties of wheat: Dewata, Basribey and G-21 were treated with gamma irradiation with a dose 100, 200, 300, 400, 500, and 600 Gy. Each treatment was repeated three times. The highest percentage of germination and vigor index due to the combination of treatment of wheat varieties with gamma rays was the combination of Dewata and 200 Gy which was significantly different from Basribey and G-21. Gamma irradiation treatment of 100 Gy on the three mutant wheat varieties showed differences in plant height, namely the G-21 variety, followed by Dewata and Basribey. The number of productive tillers showed significant variation between the gamma ray treatments for each mutant wheat genotype and the most productive tillers were at a gamma ray dose of 100 Gy for all wheat genotypes. The 100 Gy gamma ray treatment caused the number of seeds of the Dewata variety to be much higher than that of Basribey and G-21. The mutants obtained with the desired characters are the basic materials in assembling new superior varieties of wheat that are adaptive in the lowlands.
