S. zeamais pest control commonly used fumigant insecticides that used still has many disadvantages such as food safety impacts, environmental pollution and pest resistance, so that a safe alternative to control was needed, one of which was using noni seeds. This research was aimed to obtain a dose of noni seed flour that was effective to S. zea mays corn powder pest mortality.The research was conducted at the Laboratory of Plant Pest, Faculty of Agriculture, University of Riau from March to May 2018.The treatment used was the dose of noni seed flour 0 g.100 g-1 corn, 2 g.100 g-1 corn, 4 g.100 g-1 corn, 6 g.100 g-1 corn, and 8 g.100 g-1 corn. This research was conducted experimentally using a completely randomized design (CRD) with 5 treatments and 4 replications. Based on the results of the research, the dose of noni seeds 8 g.100 g-1corn had not been effective in controlling S. zeamais with mortality of 52.50%, shrinkage of corn seed weight by 8.78% and an increase in individuals by 8.20.

The predominant sand tin tailing conditions and poor nutrients cause limited plant growth above them. This research tested some kind of fertilizer treatment on sand tailing media after tin addition by using elephant grass plants. The results showed that the type of fertilizer had significant effect on the specific leaf area variant, the ratio of leaf area and the leaf weight ratio. Overall growth were greatly depressed on the 100% tailings treatment. Lime applied in conjunction with NPK fertilizer was not show the total leaf weight that was different from the addition of NPK alone. NPK fertilizers better influence the growth of elephant leaves in tin tailings than organic fertilizers. The best treatment was obtained on organic fertilization with NPK inorganic fertilization. The association of total dry weight of elephant grass with specific area of elephant grass leaf was only visible in organic fertilization treatment together with NPK inorganic fertilizer. In the best condition of elephant grass growth, the specific leaf area had a significant role to increase the total weight of the plant with the value of r2 = 0.864 or LDS will affect the total dry weight of elephant grass in the tailings medium with the addition of organic and inorganic materials NPK of 86.4 percent the remaining 13.6% increase in total dry weight was influenced by factors other than specific leaf area.","PeriodicalId":55827,"journal":{"name":"Jurnal Agroekoteknologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69563991","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}
