Abstract

The greatest problem of modern agricultural practices is the use of chemical pesticides and fertilizers. It is noted that about 40% of the world's land surface is used for agriculture. The way this agricultural land is managed has a great influence on the global environment. Integrated Pest Management (IPM) farming system produces fewer negative externally affects, can effectively restore ecosystems and deliver well ecosystem services. Depending on methods applied and degree of production, agricultural practices impact biodiversity in the ecosystem and it also influences conservation practices within the ecosystem. The result showed that diversity of soil fungi on IPM was higher than diversity on conventional one. Trichoderma sp. and Acremonium sp. which are known as antagonist fungi were found on IPM but not on conventional one. Domination Index on IPM was lower than conventional field. Bacterial leaf blight (Xanthomonas oryzae) disease intensity showed no difference on both systems. The yield on IPM was higher (6.34 ton/ha) than conventional field (5.56 ton/ha). It has been found that rich biodiversity in agricultural environment improves productivity of agricultural systems. The IPM system gives more regard to the soil fungi biodiversity and considers it as an integrated system upon which the success of the agricultural production depends.Keywords : Integrated Pest Management, biodiversity, soil fungi, modern agricultural

Abstract

One of the obstacles in the efforts to increase soybean production in Indonesia is disease such as damping off which is caused by Sclerotium rolfsii. In East Java, the intensity of S. Rolfsii reached approximately 8.61% that spread all over Indonesia region, even in our neighbor countries such as Malaysia, Thailand and the Philippines. This research was carried out to determine the efficacy of Actinomycetes and VAM (Vesicular Arbuscular Mycorrhizal) against damping-off attack and the diversity of microorganisms in rhizosfer. Research conducted in the laboratory and screen house on Plant Protection Department, Faculty of Agriculture, University of Brawijaya and in Lawang District Malang. Observation variables include level of pathogen attack and infection rate of dampingoff pathogen. Plant height, number of pods, pod weight, seed weight and weight of 100 seeds from each treatment, diversity and identification of microorganisms in rhizosphere were also observed. The results showed that Actinomycetes and VAM application could decrease the percentage of plant death due to damping-off. Application of Actinomycetes and VAM gave effect on microorganism diversity of Ratai Rhizosphere but not on Wilis. Keywords: Sclerotium rolfsii, vesicular arbuscular mycorrhizal, actinomycetes, and rhizosphere

Abstract

The experiment tested four treatments, namely inoculation of soil with mycorrhiza, inoculation of soil with mycorrhiza and cattle manure, inoculation of soil with mycorrhiza and rock phosphate, and inoculation of soil with mycorrhiza and inorganic fertilizers. Soil without any inoculation was provided as control. The treatments were arranged in a Completely Randomized Design with four replications. Soil fertility status was based on the concentrations of N, P, K, and organic-C as well as soil pH. Plant performance was determined based on its ability to uptake nutrients (N, P, K, and Ca), its growth and yield. Then, the activity of mycorrhiza was measured based on total population and percentage of root infection. Overall, results of the present study showed that, compared with other treatments, inoculation of mycorrhiza into soil and amended with cattle manure significantly performed higher concentrations of N, P, K, and organic-C. This soil condition caused soybean to absorb significantly higher nutrients, grew well with higher yield compared with plant performance in other treatments. Therefore, results of this study implies that the application of mycorrhiza into soil amended with organic matter is promising to sustain soil productivity under soybean cropping system.  Keywords: Arbuscular Mycorrhiza, soil fertility, soybean yield, dryland

Abstract

Arbuscular mycorrhizal fungi (AMF) are ubiquitous organism that forms association with the root of most terrestrial plants. AMF association also influence soil fertility through the enhancement of chemical, biological and physical content. In this study, we enumerated AMF spores from rhizosphere of Tithonia difersivolia as an indicator of soil fertility. The results showed that the most fertile soil had the highest AMF spores density. This research has confirmed that AMF has high interaction with organic carbon, organic matter, total phosphorus, cation exchange capacity, water level, soil fungi and soil bacteria. Partial regression analysis revealed the mathematic equation for their interaction. This equation used the abundant of AMF spores as an indicator for chemical, biological and physical fertility of the soil.                 Keywords: Arbuscular mycorrhiza fungi (AMF), indicator, soil fertility, Tithonia difersivolia

Abstract

Leaf blight disease is one of the most dangerous diseases of maize plant. This disease be able causing loss of maize harvest up to 40-70%. The cause of the leaf blight disease is Helminthosporium turcicum fungi. Biological control with endophytic fungi potentially used to control the pathogens as well as increase the resistance of plant induction to disease. Research was conducted in PT Bisi Inernational area, Tbk Farm Ngantang Malang Regency, Laboratory of Mycology Department of Plant Pest and Disease, Faculty of Agriculture Brawijaya University and Bioscience Laboratory Brawijaya University on December 2016 until July 2017. The exploration result of endophytic fungi of three varieties of maize were obtained 30 isolates, consisting of 14 non-pathogenic isolates and 16 pathogenic isolates. Based on the power inhibition percentage to the highest growth of H. turcicum is a fungi with NuII2, NuII4, PuIII3, DuIII3, NuII3 and PuIII1 isolates code. The most prevalent inhibition mechanism is pathogens and endophytic fungi competition. The 30 isolates identified were Colletotrichum sp, Fusarium sp, Curvularia sp, Acremonium sp dan Paecilomyces sp, meanwhile the other endophytic fungi is only found sterile hyphae thus difficult to identify up to the genus level.
