Sugar palm seed germination does indicate by the appearance of a tissue that extends like a sponge called apokol which is penetrating the hard seed coat and can occur in several positions in germinated sugar palm seeds. No research reports discuss the relationship between this apokol position and the phenology of sugar palm seed germination. This research aims to study the relationship between apokol position and the growth of sugar palm seedlings and their genetic diversity. The research applies Experiment in Completely Random Design with four treatments, each repeated five times. The four treatments are the apokol position, namely A: Apokol in right-center, B: Apokol in left-center, C: Apokol in left-bottom, and D: Apokol in right-bottom. The results showed that the fastest time for the coleoptile emergence was 40 days after transplanting in the right-center apokol position. Morphologically, there was no significant difference in the sugar palm seedling growth with each apokol position. On the other hand, we found that there were genetic diversities among them revealed by Simple Sequence Repeat (SSR) markers. The palm seeds with the right-center apokol position included the first cluster, and the second cluster consisted of left-center apokol, right- bottom apokol, and left-bottom apokol.

Indonesia has 26,000 species of orchids that are very potential and profitable. Grammatophllum stapeliiflorum is an orchid species that is increasingly difficult to find in its natural habitat. The addition of foliar fertilizer containing macro and micro nutrients can increase plant growth. The purpose of this study was to determine the effect of foliar fertilizer type, concentration and the combination of the two factors on the growth of the orchid protocorm G. stapeliiflorum. This study used a factorial completely randomized design with two research factors, namely the type of foliar fertilizer with 2 treatment levels, B1 = Gandasil-D and B2 = Growmore. The second factor, fertilizer concentration with 4 treatment levels, namely A0 = control (without foliar fertilizer), A1 = 1 g/L, A2 = 2 g/L, and A3 = 3 g/L. This study consisted of 8 treatment combinations which were repeated 4 times, resulting in 32 experimental units. The parameters observed were the percentage of live explants, the percentage of browning, and the percentage of protocorms growth stages. Data were analyzed by Analysis of Variance (ANOVA) and continued with Duncan's Multiple Range Test (DMRT) at a 5% level. These results indicated that the application of foliar fertilizers with Gandasil-D and Growmore affects the percentage of live explants and protocorm growth phases and also increase the percentage browning until of 32,5%. Gandasil-D is better for protocorm growth from globular to torpedo. The control is better for forming shoot of 22,5% compared to the use of foliar fertilizer.

Biochar with a high organic matter composition is considered to be an ameliorant for Ultisol. Providing biochar as an ameliorant needs to be studied because it will cause an increase in micronutrients, most of which are excessive in Ultisol. This study aims to determine the effect of several levels of biochar dosage from corn cob as a base material on changes in micronutrients in Ultisol soil. This research was conducted in a greenhouse and in the Laboratory of Agrostology, Feed Industry and Soil Science, State Islamic University of Sultan Syarif Kasim Riau. Experiments with several doses of biochar as treatment, e.g., 0%, 5%, 10%, and 15% of the composition of the growing media were arranged in a Completely Randomized Design (CRD) with six replications. The parameters observed were the micronutrient content of Boron (B), Copper (Cu), Zinc (Zn), Iron (Fe) and Aluminum (Al). The experimental results showed that giving corn cob biochar with doses of 0.5%, 10% and 15% did not significantly change the levels of B, Cu and Zn Ultisol. Biochar at a dose of 10% significantly increased the soil Zn content and decreased Al-dd Ultisol solubility.

Lettuce is a vegetable crop with a demand that continues to increase yearly. This situation is influenced by increasing public awareness of healthy lifestyles and urban farming practices. Diverse genetic sources are essential in plant breeding programs to form varieties with superior characteristics to increase productivity. One of the methods that can be done to improve genetic variation is by introduction. This research aims to study the morphological characteristics of three varieties of introduced lettuce. This research was conducted in the experimental field of the Faculty of Agriculture, Universitas Muhammadiyah Jakarta, from July to November 2022. The study compared three introduced lettuce varieties from Turkiye and three national commercial varieties. The morphological characteristics observed included qualitative (leaf shape, leaf vein shape, leaf tip shape, and leaf colour) and quantitative (crop height, number of leaves, leaf width, leaf length, harvest age, gross weight, and consumption weight). The results showed that only V4 had the same qualitative characteristics as its comparison variety (V1). The results also showed that in terms of quantitative characteristics, V4 and V5 had a higher resemblance to their comparator varieties (V1 and V2, respectively), while V6 had a further similarity to its comparator variety (V3). These introduced varieties have phenotypic variability that can be used as sources of plant genetics for plant breeding programs.

Soybean is one of the main needs and sources of vegetable protein for Indonesian. National needs of soybean continue to increase in line with the increase of population, but soybean production has not been able to meet national needs. Therefore, efforts need to be made to increase soybean production by utilizing marginal land with using arbuscular mycorrhizal fungi and biochar. The aim of this study was to determine the effect of single factors of arbuscular mycorrhizal fungi (AMF), biochar and interaction of these two factors on the growth and yield of soybean in Ultisol soil. This research was conducted from December until March 2019. The research used 3 x 3 factorial completely randomized design with three replications. The first factor was AMF dosage consist of 3 levels : M0 (0 g per plant), M1 (15 g per plant), M2 (30 g per plant) and the second factor was type of biochar consist of 3 levels : B0 (without biochar), B1 (biochar of rice husk), B2 (biochar of coconut shell). The observation data that obtained were analyzed statistically using analysis of variance (ANOVA). The results of variance analysis were continued by Duncan's multiple range test at level 5%. The results showed that the treatment of AMF improved all growth and yield parameters and the single biochar can not improve all growth and yield parameters. The interaction between AMF and biochar did not improve all parameters of growth and yield of soybean.
大豆是印尼植物蛋白的主要需求和来源之一。随着人口的增加，国家对大豆的需求也在不断增加，但大豆的产量一直不能满足国家的需求。因此，应努力利用边际土地，利用丛枝菌根真菌和生物炭提高大豆产量。本试验旨在研究丛枝菌根真菌(AMF)单因子、生物炭及其互作对Ultisol土壤中大豆生长和产量的影响。这项研究从12月到2019年3月进行。本研究采用3 × 3阶乘完全随机设计，3个重复。第一个因子是AMF用量，由M0 (0 g /株)、M1 (15 g /株)、M2 (30 g /株)3个水平组成;第二个因子是生物炭类型，由B0(不含生物炭)、B1(稻壳生物炭)、B2(椰壳生物炭)3个水平组成。获得的观察资料采用方差分析(ANOVA)进行统计学分析。方差分析结果在5%水平下继续进行Duncan多元极差检验。结果表明，AMF处理提高了所有生长和产量参数，而单一生物炭处理不能提高所有生长和产量参数。AMF与生物炭互作对大豆生长和产量的影响并不明显。

The first factor was AMF dosage consist of 3 levels : M0 (0 g per plant), M1 (15 g per plant), M2 (30 g per plant) and the second factor was type of biochar consist of 3 levels : B0 (without biochar), B1 (biochar of rice husk), B2 (biochar of coconut shell). The observation data that obtained were analyzed statistically using analysis of variance (ANOVA). The results of variance analysis were continued by Duncan's multiple range test at level 5%. The results showed that the treatment of AMF improved all growth and yield parameters and the single biochar can not improve all growth and yield parameters. The interaction between AMF and biochar did not improve all parameters of growth and yield of soybean.","PeriodicalId":340373,"journal":{"name":"Jurnal Agroteknologi","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129568585","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}
