In general, chrysanthemums are cultivated as cut flowers and potted flowers. The diversity of colors and shapes of chrysanthemums and the low rate of flower wilting are the main attractions of chrysanthemum plants. The demand for chrysanthemum flowers increases by 25% every year so that cultivation and production technology is needed to meet the needs of the national market. Fertilization is the addition of nutrients to plants to increase plant growth and development. One of the materials that can be given to plants is biochar. This study used one treatment in a Randomized Block Design (RAK) with four replications. The treatment of the composition of the growing media consisted of 4 levels. Observations were made on the growth of chrysanthemum plants including plant height and number of leaves. The results showed that the planting media treatment with a composition of 50% soil + 50% biochar produced the best plant height and number of leaves compared to other treatments. This shows that the addition of biochar with the right ratio in the growing media can increase the growth of chrysanthemum plants.","PeriodicalId":274098,"journal":{"name":"JURNAL AGROTROPIKA","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126594156","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}

Basal stem rot disease is a major problem in oil palm cultivation. This study utilized secondary data, namely production data for 2003-2016, tree population data and the incidence of Ganoderma disease observed in 2016 in plantation company in South Lampung. The yield gap is measured using the productivity performance index, namely the ratio between actual productivity and potential productivity of land with S3 land suitability. The results showed that: (1) The tree mortality rate in young oil palm plants was significantly lowest at 0.67 trees per year compared to the juvenile, adult and old age categories ranging from 1.6 to 1.9 trees per ha per year. The number of dead and diseased trees increases in linear regression with increasing age; (2) Ganoderma attack in the heavy category was more common in juvenile, mature, and old plants. In young plants, the incidence of severe attack was 0.4 trees per ha, while in juvenile, mature and old plants it ranged from 1-2 plants per ha and there was no significant difference between juvenile, adult, and old age categories. There was no significant difference in the incidence of light attack between age categories, ranging from 1.6 to 2.6 trees per ha; (3) Heavy attack of Ganoderma affects yield performance linearly. Plantation groups with different generations of planting years showed different yield trends. The two plantation groups both reached peak production of 18 FFB/ha/year which was achieved at different ages. Yield declines occur more rapidly in the next generation of replanted gardens as a degeneration symptom.

For this reason, it is necessary to make efforts so that mangosteen seedlings can have a good root system through the addition of natural growth regulators. The purpose of this study was to determine the effect of red onion extract, a mixture of onion extract and mung bean sprouts combined with biological liquid fertilizer on the growth of mangosteen seedling. This research was carried out in the Horticulture FP greenhouse in March 2020–July 2020. This study was arranged in a factorial (3 x 2) in a Randomized Block Design (RAK) with three replications. The first factor was natural ZPT treatment: without extract, red onion extract 400 g/L, and mixed extract of onion 200 g/L and green bean sprouts 200 g/L. The second factor is the provision of biological fertilizers, namely without biological fertilizers and 15 ml/L). The results showed that the administration of mixed extracts of shallots and mung bean sprouts tended to have better growth which could be seen from the highest average value for the variable plant height 6.04 cm, stem diameter 2.93 mm, and the number of secondary roots.
