Study of Trichoderma Spp. Application on the Incidence of Moler Disease and Shallot\u27s Growth and Yield
No full textFusarium wilt disease/moler is a concern in onion cultivation. Many farmers apply chemical pesticides such as azoxystrobin and difenoconazole to control the diseases. Both of these chemical pesticides are currently exhibiting a decline in effectiveness, prompting farmers to increase the dosage and frequency of application. Recommendations for biological control, including Trichoderma spp..
This study aimed to determine the influence of application time of of Trichoderma spp. in various media types on the incidence of moler disease and shallot growth and yield. This study was conducted in Tabalong district, South Kalimantan, from February to June 2019 using a completely randomized design (CRD) factorial comprising two nested designs. The first factor was the type of media in which Trichoderma spp.. was applied, namely solid and liquid. The second factor was the application time of Trichoderma spp.. Level 1 was the application of Fusarium sp. seven days before planting and Trichoderma spp.. seven days after planting. Level 2 included the application of Trichoderma spp.. seven days before planting and Fusarium sp. simultaneously during planting. Level 3 involved the administration of Trichoderma spp.. concurrently with planting and Fusarium sp. seven days later. This investigation used one positive control (without treatment) and one negative control (shallots inoculated with Fusarium). Each experimental unit was consisted of ten plants and replicated three times. The parameters observed were the incubation period of Fusarium sp., disease incidence, number of leaves, plant height, number of cloves, and average clove weight. The study found that the application time of Trichoderma on various types of media affected the incidence of Fusarium disease, the number of leaves, and the number of shallot cloves.When compared to liquid media, the application of solid media resulted in a reduced incidence of Fusarium disease and a greater frequency of flares. The application time on solid media gave a low response to moles. As for liquid media, the lowest incidence of moler disease occurred at the seven days before planting

The Utilization of Rice Straw for Increase Orange Productivity and Reducing Environmental Pollution
Full text linkSiam Banjar oranges was one of the leading commodities in South Kalimantan with an area 2,594 ha, 113,-149 tons of production and 43.72 ha-1 of productivity (Department of Agriculture South Kalimantan, 2006 in www.kalselprov.go.id/). The development of Siam Banjar oranges in South Kalimantan was overflow in Barito Kuala and Banjar District. The level of responsiveness plants for fertilization encourages farmers to apply high inorganic fertilizers. If it is applied continuously and without return organic matter into the soil, it will produce the reduced soil fertility in terms of chemical, physical, and biological soil. This research showed the effect of the use of straw in increasing the production of Siam Banjar oranges. First, they completely decomposed so that increasing soil fertility. Second, reduce environmental pollution because it did not leave residues as inorganic fertilizers. Third, prevent soil erosion so that nutrients needed by oranges for grow properly could be fulfilled optimally. So, oranges did not easily attacked by pests and diseases then provide abundant harvest. The results of the differences between two values could be concluded that, the benefits of orange farming was produced with straw was greater than farming without straw. Revenue Cost Ratio (RCR) value of orange farming with straw was 3.56 and the Revenue Cost Ratio (RCR) value of orange farming without straw was 3.26. Based on the RCR value, orange farming with straw was more feasible than orange farming without a straw
