Abstract

Sopialena, Akhsan N, Suryadi A, Nurdiana J. 2018. The identification of soil fungi isolated from Rhizosphere in different varieties of jali plants (Coix lacryma-jobi) in Loa Kulu, Kutai Kartanegara, Indonesia. Asian J Agric 2: 44-47. The rhizosphere effect indicated the development of active microbial population around the roots driving from the loss of organic materials. This research was intended to identify rhizosphere microbes by identifying the potential microbes four different varieties of jali (Coix lacryma-jobi L.) in Loh Sumber, Loa Kulu, Kutai Kartanegara, Indonesia, i.e., jelai beras, jelai ketan, ketan lekat, and jelai kaltara. The soil samples were collected and isolated in the area of jali plantation in Loa Kulu, Kutai Kartanegara at 45 days after planting. As many as 16 isolated samples were used, collected from four different variety of jali and 4 times of replication. The result showed that a variety of microbes at Rhizosphere could be classified as Trichoderma sp. Aspergillus sp., Pythium sp., Fusarium sp., Cunninghamelal sp., and Penicillium sp..

Abstract. Akhsan N, Sopialena, Fahrizal. 2019. Plant resistance to leaves and their effects on paddy rice production in Kutai Barat District, East Kalimantan Province, Indonesia. Asian J Agric 3: 41-46. This study was aimed to evaluate the effect of fertilizer application on the resistance of lowland commercial rice cultivars (Oryza sativa L.) against leaf spot diseases in Kutai Barat District, East Kalimantan Timur, Indonesia and to determine the factors influencing the resistance. A field experiment was conducted at rice fields in Long Iram and Linggang Bigung Sub-districts, West Kutai District and the disease identification was performed at the Laboratory of Pests and Diseases, Faculty of Agriculture, Mulawarman University. The field experiment was designed in a split-plot design arranged in a Randomized Block Design (RBD) using four replications. The main-plot was fertilizer application (P) consisting of two fertilizer application treatments, i.e., 200 kg.ha-1 Urea (p1), and 200 kg.ha-1 Urea + 200 kg.ha-1 NPK (p2). The sub-plots were varieties (V) consisted of three varieties, i.e., Ciherang (v1), Mekongga (v2) and Inpari 6 (v3). The disease identification was performed by identification of leaf spot disease isolated from the sample plants using morphological observation under a microscope. The number and density of stomata, intensity of leaf disease infection, and yield of the rice were observed. The humidity was also measured at the time of observation of leaf spot disease intensity. The results showed that different fertilizer treatments did not affect the leaf spot disease intensity but the varieties affected the disease intensity at 7, 14, 21.35 and 49 days after planting. The number of stomata of Ciherang, Mekongga and Inpari 6 varieties was 230,182 and 236 stomata/mm2, respectively. Ciherang variety was more resistant against the leaf spot disease compared to other varieties. Stomatal density does not always affect the intensity of leaf spot disease in lowland rice. There is a correlation between air humidity and the intensity of leaf disease infection. The interaction between fertilization and varieties was significant for the rice yield and the highest yield was obtained by Ciherang variety fertilized with 200 kg.ha-1 Urea + 200 kg ha-1 NPK about 3.58 Mg.ha-1 (grain wet weight).In conclusion, Fertilizer application does not affect the leaf spot disease infection and Ciherang variety is the most resistant plant against leaf spot disease compared to Mekongga and Impari 6 varieties.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi jenis jamur endofit yang terdapat pada tanaman padi serta potensinya sebagai pengendali hama atau entomopatogen. Jamur endofit merupakan mikroorganisme yang terdapat didalam jaringan tanaman yang mengandung senyawa yang dapat memberikan ketahanan pada tanaman inang dari serangan Organisme Pengganggu Tumbuhan.Penelitian dilakukan dalam dua kegiatan, yaitu kegiatan lapangan dan kegiatan laboratorium. Kegiatan lapangan yaitu pengambilan sampel tanaman padi yang sehat. Kegiatan di Laboratorium meliputi isolasi, identifikasi dan uji entomopatogen.Hasil penelitian menunjukan bahwa jamur endofit yang teridentifikasi pada tanaman padi dari dua lokasi penelitian yaitu di Desa Karang Tunggal, Tenggarong Seberang dan Kelurahan Tanah Merah, Samarinda Utara terdapat 4 jenis, yaitu Metarhizium sp., Penicillium sp., Aspergillus sp., dan Trichoderma sp.

Abstract

Planting activities are undergoing in the area of former forest with mechanism of extrication of forest area or non-forest area that commonly has high conservation value or known as High Conservation Value (HCV). However, the extrication of forest area for Palm Plantation has eroded the presence of forest with HCV disrupting ecosystem balance and harming the wellbeing of current and next generations. Legal system does not specifically regulate the limit of application for the use of forest area for palm plantation through the mechanism of forest extrication. Legal provisions at the national and regional levels encounter a difficulty accommodating the existence of area with HCV, especially in terms of regional spatial plans. Moreover, the obscurity of forest distribution and non-forestry areas with HCV also complicates the regulation at the level of imperative provisions.

Abstract

The effectiveness of some modes of mosaic virus transmission in chili plants.  This study aims to determine the persistence of the mosaic virus in chili and techniques as well as effective mosaic virus infection on chili plants. The experiment was conducted for about four months from land preparation up to the last data collection. Research conducted at the Green House Agronomy Faculty of Agriculture, University Mulawarman. Research and laboratory tests carried out on 35 samples of chili fruit crops, which consists of 25 pieces of diseased plant samples and 10 samples of healthy plants. The results showed that the cause of the mosaic disease in pepper caused by viruses, which dibuktikakan with some testing include: watering with tetracycline antibiotics for 10 days on diseased plants did not show symptoms of healing. Grafting (grafting) between healthy and diseased plants plants rnenunjukkan healthy plant mosaic experience symptoms at week 4 (the virus moves through the vascular tissue). Vector Myzus persicae were introduced into healthy plants for 7 days successfully transmit the virus to healthy plants that exhibit the same symptoms on day ll. Mechanical transmission is not successfully transmit the virus to healthy plants until day 4 after inoculation. The most effective method of infection is by using subsequent grafting by using insects. Meanwhile mosaic virus transmission by mechanical means is not effective because there are no infected plants after mechanically inoculated.
