Abstract

This study aimed to investigate the optimization of Ultisol soil using biochar and compost to increase nodule formation and performance of soybeans. The trial was conducted at the Research and Teaching Farm, Faculty of Agriculture, University of Jambi, for six months from April through to October 2021. Three levels of compost (5 t ha-1, 10 t ha-1, and 15 t ha-1) were tested in combination with three levels of biochar (5 t ha-1, 10 t ha-1, and      15 t ha-1). A completely randomized design was employed with three replications. Each experimental unit consisted of 20 plants, and 25% of the population was taken as sample plants. Results indicated that the application of soil ameliorant in the form of Tithonia compost and biochar could increase soil pH and nutrient contents and reduce C/N ratio. Tithonia compost + biochar improved Ultisol productivity as indicated by increased nodule formation and soybean growth. The combination of Tithonia compost and biochar, each of 15 t ha-1, was the best combination for the optimization of Ultisol, which produced the highest biological nitrogen fixation rate and resulted in the best soybean growth.

Abstract

CVPD disease is an important disease in citrus plants. This disease can reduce the productivity of citrus plants. This study aimed to detect the transmission of CVPD disease by using inoculum sources from various diseased tissues. The experimental design used was a completely randomized design with a two-factor factorial pattern. The first factor was the level of symptoms of the inoculum source (partially symptomatic, and fully symptomatic), while the second factor was the diseased plant parts as a source of inoculum, namely: leaf tissue, middle leaf bone, woody twig tip, woody middle twig, middle twig without wood, woody roots, and root bark. Response data of diseased plants inoculated by grafting various diseased tissues were obtained through variables: incubation period, percentage of leaf chlorosis, and percentage of symptomatic branches. The results showed that the incubation period of CVPD disease, percentage of symptomatic branches, and percentage of leaf chlorosis on Rough Lemon citrus plants inoculated with CVPD pathogens from plants with overall symptoms was faster and the percentage was higher than those with partial symptoms of all types of diseased tissue, except the middle tissue of twigs and roots without wood. A faster incubation period was te

Abstract

Downy mildew disease in soybeans is caused by the obligate fungus Peronospora manshurica. The existence of this fungus is still limited in Indonesia. This study aimed to determine the viability of the fungus oospore P. manshurica on seeds carried on imported soybeans from Malaysia. Detection of oospores in soybean seeds was carried out by two methods: 1) Detection of soybean seeds without scale symptoms was carried out by washing or washing test techniques, and 2) Detection of soybean seeds with crust symptoms was carried out by direct examination. Oospora of P. manshurica obtained was tested for viability at the Mycology Laboratory of the Class I Agricultural Quarantine Center Jambi. Morphology observations included Oospora size, Oospora color, Oospora shape, and hyphae shape using a multi-media compound microscope (Olympus BX 51 and Olympus DP 20 camera). Oospores were observed in 10 drops of 10 l each of the precipitate suspension of each test sample. The results showed that the fungus P. manshurica on imported soybeans from Malaysia still had potential as an inoculum causing Downy mildew in soybean plants with a viability level of 3.35 - 9.93%. Morphology of Oospora P. manshurica were, diameter of 24 - 38µm, smooth and spherical shape with an irregular surface, hyaline to light brown in color. Hyphae were thick and thin-walled with varying densities. Viable oospores were marked with a reddish-orange color.

Abstract

Soybeans are a plant that has great opportunities and promising prospects to be cultivated, but there are often problems in this cultivation such as the problem of seed setback. The gradual process of degradation of seed quality and vitality, known as seed deterioration, cannot return to its original state or be restored. Soybean seeds that have expired so far are no longer used, because their short shelf life makes them only usable for consumption. Using invigoration techniques is one method to control seed setback. Matriconditioning is a treatment that utilizes moist solid media, such as charcoal, husks, and sawdust. This research aims to investigate the effect of husk charcoal on the viability and vigor of soybean seeds, as well as its effects on soybean growth and yield (Glycine max (L). Merril). This research lasted about 4 months, starting in November 2022, , and was carried out at the Seed Technology Laboratory and Teaching and Research Farm, Faculty of Agriculture, University of Jambi and was carried out in two stages. This research was carried out simultaneously, namely Phase I of the research was carried out in the laboratory, while Phase II was carried out in the field. The results of the study showed that invigoration treatment with matriconditioning had a significant effect on germination power, maximum growth potential, normal germination dry weight, and growth speed. The treatment of planting media has a real effect on the weight of planting seeds and the number of pods per plant. Matriconditioning treatment had no noticeable effect on plant height, dry weight of the plant, root nodules, seed weight per plant, and number of pods per plant. Matriconditioning treatment has a real effect on the leaf area index.

Abstract

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo), and the blast caused by Pyricularia oryzae can decrease rice production about 60% and 70%. The study aimed to determine the effect of rhizobacterial and endophytic bacterial isolates on BLB, blast, and the growth of rice plants, and also the characteristics of those biological agents. The isolates used were BR-IP3 dan BR-BC1 (bacterial isolates), BE-KR3 dan BE-KT2 (endophytic bacterial isolates). The rice varieties used Indragiri, Ciherang, and Inpara 3. The results showed that the application of various biological agents on rice seed of Indragiri, Ciherang, and Inpara 3 varieties were able to reduce the HDB of 80-100% and the blast of 31.8-88.6%. The isolates of BR-IP3 and BE-KR3 could dissolve phosphate and fix nitrogen, whereas the isolates of BR-BC1 and BE-KT2 were only able to dissolve phosphate.

Abstract

Penelitian ini bertujuanuntuk mempelajari penularan penyakit CVPD melaluivektor Diaphorina citri stadia imago dan nimfa pada jeruk Siem dan Rough Lemon. Percobaan dilaksanakan dengan menggunakan Rancangan Acak Lengkap pola faktorial dua faktor.Faktor Kultivar Jeruk (Rough Lemon, dan Siem) diletakkan sebagai faktor pertama, sedangkan fakor stadia vektor (Nimfa, dan Imago) sebagai faktor kedua. Empat kombinasi perlakukan masing-masing diulang 5 kali.Tiap perlakuan terdiri dari 2 pot tanaman percobaan.Data respons tanaman terhadap penyakit CVPD yang diinokulast melalul vektor D.citri berbeda stadia diperoleh dengan menghitung:1) masa inkubasi yang diperoleh dengan cara mengamati lamanya waktu yang diperlukan tanaman sejak diinokulasi patogen sampai timbulnya gejala pertama;2) persentase daun klorosis yang diperoleh melalui pengamatan daun sampel yang diambil secara acak dan dihitung jumlah daun yang klorosis dari jumlah daun tanaman sampel, 3) persentase cabang yang bergejala, diperoleh dengan menghitung jumlah cabang yang bergejala dari jumlah cabang seluruhnya per tanaman tiap perlakuan.Hasil penelitian menunjukkan bahwa masa inkubasi penyakit CVPD, persentase daun klorosis, dan persentase daun bergejala lebih cepat dan lebih tinggi pada jeruk Siem dibandingkan dengan pada jeruk Rough Lemon, baik yang ditulari melalui inokulasi dengan D. citri stadia imago maupun stadia nimfa. Tetapi penularan melalui inokulasi D. citri pada stadio imago lebih cepat memunculkan masa inkubasi, persentase daun, klorosis, dan persentase cabang bergejala lebih tinggi dibandingkan dengan stadia nimfa. Jeruk siem dan penularan penyakit CVPD melalui D. citri stadia nimfa dapat dijadikan cara deteksi dini penyakit CVPD pada jeruk
