{"title":"Ganoderma spp. Basidioma Variation from Infected Oil Palm on Smallholder Peatland Plantation in Kampar Regency, Riau, Indonesia","authors":"R. Saputra, A. Hamzah, F. Puspita, B. Nasrul, Irfandri","doi":"10.2991/absr.k.210609.009","DOIUrl":"https://doi.org/10.2991/absr.k.210609.009","url":null,"abstract":"A total of 15 types of Ganoderma diversity in the world have been identified. In Indonesia, information related to the variety of Ganoderma has not been widely reported. Ganoderma is the main cause of stem rot disease of oil palm plants, which has been reported to attack at various stages of plant growth. Information regarding the genetic diversity of Ganoderma needs to be known, considering that each pathogen has specificity in causing disease. This information is necessary to determine how the mechanism of infection, spread, and the response of plants to the presence of each type of Ganoderma in the physiological processes of oil palm plants. This research was conducted using survey methods in smallholder oil palm plantations in Kampar Regency and the Plant Disease Laboratory, Faculty of Agriculture, Riau University. The basidioma of Ganoderma spp. taken from the trunk of the infected oil palm tree. Basidioma of Ganoderma spp. then characterized based on its color. The data from these observations were then analyzed descriptively and presented in the form of tables and pictures. Field observations indicate that the presence of Ganoderma basidioma at the oil palm trunk is closely related to visual plant symptoms. Based on symptom observation results showed 62.07% severe symptoms, 10.34% dead plants, 20% had moderate symptoms and only 6.90% had mild symptoms. The plant condition in Deli Makmur Village shows severe symptoms with a severity index reaching 75%. There were 6 groups of Ganoderma based on the characteristic color variations of the basidioma found in the sample locations. The Gano-1 group is the group with the highest incidence found in the field. This study also found 48% of infections of more than one Ganoderma group in one oil palm plant. Further testing is needed to determine the diversity of this Ganoderma species based on its genetic characteristics.","PeriodicalId":20642,"journal":{"name":"Proceedings of the International Seminar on Promoting Local Resources for Sustainable Agriculture and Development (ISPLRSAD 2020)","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82904802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological control is one of the environmentally-friendly control measures of the disease. Vermicompost is a potential source of antagonistic microbes for biological control of plant diseases. The objective of this study were to isolate fungi from vermicompost water extract and examine their abilities to inhibit the growth of A. solani in vitro and suppress the pathogen infection in tomato fruits and leaves. The fungi were isolated from water extract of two types of vermicompost which were cattle manure vermicompost and goat manure vermicompost. The fungal isolates obtained were tested for their antagonistic abilities against A. solani in vitro using adual culture method. The in vitro experiment was arranged in Completely Randomized Design. The selected isolates were examined their abilities in suppressing A. solani infection in tomato fruits and early blight disease in tomato leaves. The in vivo experiments were arranged in Randomized Complete Block Design. The isolation of fungi from the water extract of two types of vermicompost resulted in 14 fungal isolates, which were nine isolates from cattle manure vermicompost and five isolates from goat manure vermicompost. Among 14 fungal isolates, there were seven isolates that inhibited the growth of A. solani in vitro. In tomato fruits, six fungal isolates inhibited A. solani infection by 64%-76% at five days after inoculation. However, two isolates (Trichoderma spp.) colonized the fruit surface after seven days of incubation. In tomato plants, two fungal isolates (Trichoderma spp.) suppressed early blight disease in the leaves by 55.3%-58.2%. This finding showed that some fungal isolates from the water extract of vermicompost were antagonistic to A. solani in vitro and had potential as the biological control agents of early blight disease in tomato.","PeriodicalId":20642,"journal":{"name":"Proceedings of the International Seminar on Promoting Local Resources for Sustainable Agriculture and Development (ISPLRSAD 2020)","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76195221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine the response of male local duck and broiler chickens, which are given African leaf meal (ALM) in their rations, to body weight and blood lipid content. The treatment that will be given is the level of ALM usage as many as 5 levels (0%; 0.5%; 1.0%; 1.5% and 2.0%). The treatments were analyzed by completely randomized design (CRD) with 4 replications. The treatment given to 100 broilers which is reared from the age of 8 days to 35 days. As well as 80 local male ducks. The results showed that increasing of ALM usage, will increase body weight gain of male duck and broiler, about 4,23 % at ALM 1,5 % usage. Likewise, the Feed Conversion Ratio (FCR) was high significantly better (P <0.01). Blood lipid content was reduced about 20,37 % at the 1.5% ALM level (P <0.01). The use of ALM 1,5 % level can improve the quality of meat male duck and broiler, because it produces weight gain higher and lowering the lipid content, in order to create a source of healthy food.","PeriodicalId":20642,"journal":{"name":"Proceedings of the International Seminar on Promoting Local Resources for Sustainable Agriculture and Development (ISPLRSAD 2020)","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87814684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
