Salah satu cara untuk meningkatkan produksi bawang merah yaitu memperhatikan cara tanam dan pupuk yang diberikan. Pemotongan umbi bibit dapat memacu fase vegetatif yang bertujuan menumbuhkan tunas umbi yang ditanam dengan cepat. Pemupukan perlu dilakukan untuk menambah unsur hara ke dalam media tanam, karena keterbatasan tanah dalam menyediakan unsur hara yang cukup. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 3 ulangan. Faktor pertama adalah perlakuan terhadap umbi bibit bawang merah (K) yang terdiri dari dua taraf yaitu, tanpa pemotongan umbi bibit (K1) dan pemotongan umbi bibit (K2). Faktorial kedua adalah pemberian pupuk NPK yang terdiri dari 100% (N1), 150% (N2), 200% (N3), 250% (N4). Data yang telah diperoleh di analisis menggunakan analisis ragam (uji F). Apabila terdapat pengaruh yang nyata, maka akan dilanjutkan menggunakan uji BNT (Beda Nyata Terkecil) dengan taraf 5%. Penelitian ini menunjukkan perlakuan kombinasi pemotongan umbi bawang dan dosis pemupukan memberikan pengaruh nyata pada semua parameter pertumbuhan dan hasil.

This study aimed to determine the host range and virulence level of C. gloesporiodes in several postharvest fruits. The research was conducted at the Agrotechnology Intermediate Laboratory, Gunadarma University from March 2022 to April 2022. This study used a completely randomized design consisting of 4 types of fruit (mango, chili, papaya, and tomato) as treatment. Each treatment consisted of 4 units and then repeated 3 times so that there were a total of 48 experimental units. C. gloesporiodes isolate was obtained from mango fruit with anthracnose symptoms. The isolates obtained were inoculated to tomatoes, chilies, papayas, and mangoes as controls. Anthracnose symptoms and lesin diameter were observed at 7 days after inoculation. The diameter of the lesin was measured to determine the level of virulence. The results showed that C. gloesporiodes was able to colonize and infect chilies, papayas, and mangoes as hosts, but there was no inoculated to tomatoes. The ability to colonize and infect is indicated by symptoms in the form of yellow to black spots, sunken, and watery. The virulence category showed different levels in each fruit with a range from very low to moderate. The conclusions obtained from this study were that C. gloesporiodes was able to infect chilies and papayas with different levels of virulence.","PeriodicalId":325350,"journal":{"name":"Jurnal Pertanian Presisi (Journal of Precision Agriculture)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114433000","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}

The experiment was carried out from April to June 2021 at the Plant Physiology Laboratory, Department of Agronomy, Faculty of Agriculture, Andalas University, using stomatal printing method on long bean plant leaves. The experiment consisted of two stages: first, the removal of cuticle and trichome; and second, the method of application of the printing material and the drying time of the imprint. Based on the experimental results, it was found that stomatal imprint of long bean plants could be obtained without having to remove the cuticle or trichomes. Applying a thin layer of nail polish for at least 20 minutes can produce 100% imprinted stomata, while using a thin layer of adhesive glue takes at least 10 minutes. Adhesive glue can be used as an alternative to nail polish with faster drying time and clearer imprint results in the stomatal printing method. The stomata number of long bean plants is enormous, with a density of 184-237 per mm2.
