The productivity and growth of oil palm is partly controlled by the relationship between the top of the plant (the leaf) and the bottom of the plant (root). This study aims to find out the effect of root pruning and the number of fronds on the growth, production and quality of oil palm products. The research was conducted for 12 months from February 2018 to January 2019 in gardens owned by the community of Petapahan Village, Tapung District of Kampar Regency, Riau. The research was conducted experimentally using split plot design which is grouped based on different plant age (5 years, 10 years and 15 years). The main plot is the pruning of oil palm, Normal, Light, and Heavy fronds. The plot is trimming the roots of oil palm 75%, 50% and 25%. The results showed that root pruning and the number of fronds did not affect the interaction of observational premeters. Pruning the roots independently gives a noticeable influence on the content of mesocarp oil. Self-trimming of the fronds has a real effect on the total increase in oil. Plant life has a noticeable effect on enhancement, total oil, mesocarp oil and free fatty acids.","PeriodicalId":55827,"journal":{"name":"Jurnal Agroekoteknologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42714143","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}

Plants grown on marginal soil, especially saline soils, show abnormal growth due to oxidative damages causes yield decrease even death of the plants. The objectives was to study invigoration technique using natural antioxidant and mycorrhizal fungi to increase soybeans tolerance under salinity stress. The research used factorial randomized block design. The first factor was salinity stress (0 and 1 % (w/v) NaCl concentration), the second factor was natural antioxidant (0, 1, 1.5, and 2% mangosteen peel extracts), and the third factor was arbuscular mycorrhizal fungi, 0 and 1g/polybag. The research was replicated three times. The variables were plant height, number of leaves, leave area, chlorophyl content, yield components and yield of soybean. The data was analyzed with Anova and Duncan’s multiple range test at 5% significant level. The conclusion was that salinity stress inhibited plant growth, yield components and yield of soybean. The application of arbuscular mycorrhizal fungi decreased the negative impact of salinity on vegetative growth, yield components and yield of soybean. The application of 2% mangosteen peel extract gave good effect on vegetative growth, yield components and yield of soybean under salinity stress.","PeriodicalId":55827,"journal":{"name":"Jurnal Agroekoteknologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48139333","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}
