The development of management plan of the Gambella National Park is hindered by lack of information on habitat types within the park. The objectives of this research were to determine vegetation types and identify habitat types on recent satellite imageries. The method used for vegetation data collection was transects lines. PC-ORD software was used for analyzed vegetation data while Rapid Eye image 5m resolution 2012 was analyzed by ArcGIS version 10.1 to classify the habitats map of Gambella National Park. The cluster analysis classified, the Gambella National Park into 6 vegetation communities and the relative abundance and relative frequency was used for naming vegetation community types. However, the satellite image had classified the Gambella National Park into 5 major habitat types.","PeriodicalId":339003,"journal":{"name":"Cutting-edge Research in Agricultural Sciences Vol. 11","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128413630","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}

Estimating nutrient to radish green (Raphanus sativus var. caudatus) important in optimizing of compost required. Radish green is rich nutrient that need for health. As we know that compost is organic fertilizer that have proved improving in soil quality and yield of plants. Recently silicon (Si) have positive effect in yield of plant in under normal and stress condition. Based on the explained above, we conducted silicon (Si) was mixed with coffee husk compost in normal conditions with aims for improving of soil nutrient and yield of radish green. The experimental units were presented by pots under greenhouse conditions with several of dosage; Treatments consisted 100 g soil (T = control), 99 g soil + 1 g compost (1%), 97 g soil + 3 g compost (3%) in the absence (-Si) and presence of silicon (+Si) at a concentration 1 ppm SiO2 of 15 ml before sowing with two replications. Soil sample is taken in harvested time (days 21) were assessed in the pH, EC, magnesium, calcium, potassium, phosphorus and cation exchange capacity. Agronomic data were observed by counting; dry weight, stem height, leaf area and root length. The results showed that application of 3% in the absence of Si (Si-) could increase the nutrient in soil i.e magnesium (Mg) of 1.59%, potassium (K) of 4.53%, phosphorus (P) of 371.90 mg/100 g and cation exchange capacity (CEC) of 50.58 meq/100 g. While the highest of stem height, leaf area and root length were 11.48 cm, 1.24 cm and 4.02 cm, respectively. This results have correlated that the highest of soil nutrient which might highest in the yield of plant. On the other hand, the presence of silicon (Si+) which have inhibited effect on plant growth. This might indicated that the lower concentration of liquid Si mixed with coffee husk compost cannot effectively to improving of yield of radish green (Raphanus sativus var. caudatus).","PeriodicalId":339003,"journal":{"name":"Cutting-edge Research in Agricultural Sciences Vol. 11","volume":"333 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116359766","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}
