Both measurements require leaf area data. Measurement of leaf area of wheat in Indonesia requires a method that is not only accurate, but also easier and cheaper. One of them is the regression method. The purpose of this study was to determine an accurate regression equation model in predicting wheat leaf area. This research was conducted from March to June 2021 at the Experimental Station and Plant Production Technology Laboratory, Faculty of Agriculture, UNPAD, Jatinangor, Sumedang. The materials used in this study were various leaf area printing papers from wheat plants aged 14 days after planting (DAP), 28 DAP, and 42 DAP. The regression equation was assembled from the relationship between leaf area with leaf width and length, then compared with the actual leaf area that measured by scanning. The results showed that the linear, quadratic, cubic, and logarithmic regression equations had a coefficient of determination of more than 90% to predict leaf area, at the age of 14, 28, and 42 DAP, as well as all plant ages. Quadratic regression had a limit of data that can be entered, so it needed circumspection in using the formula. Cubic regression tended to have better accuracy in predicting leaf area at 14, 28, and 42 DAP, but the accuracy was the same as other regression equations at all plant ages.","PeriodicalId":136806,"journal":{"name":"Paspalum: Jurnal Ilmiah Pertanian","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131136642","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}

To meet the needs of lettuce at the request of the community and the market, an intensive cultivation technique is needed, namely the aeroponic system. The purpose of this study was to get the right timing of nutrition to produce the highest production of green lettuce plants in an aeroponic system. The research method used is an experimental method with the environmental design used is a Single Factor Randomized Block Design (RBD), which consists of 6 treatments repeated 4 times. The treatments consisted of t1 (5 minutes off, 30 seconds on), t2 (10 minutes off, 30 seconds on), t3 (15 minutes off, 30 seconds on), t4 (20 minutes off, 30 seconds on), t5 (25 minutes off, 30 seconds on), t6 (non-stop). Analysis of the data used is the F test at 5% level and to find out which treatment is the best, DMRT further test is carried out at the 5% level. The results showed that the t6 treatment gave better growth and yields than other treatments. At the age of 42 days after observation, the average plant height was 29.4 cm; the average number of leaves 15.22; the average diameter of the rods is 14.11 mm; mean root length 10.34 cm; 2003 mean leaf area, 59 cm2 ; and the average fresh weight was 670.1 g.","PeriodicalId":136806,"journal":{"name":"Paspalum: Jurnal Ilmiah Pertanian","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114388531","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}

This causes environmental problems such as air, soil, water pollution and a decrease in the quality of ecosystems and public health in industrial environments. For this reason, it is necessary to make efforts to utilize coal waste so that unwanted things do not occur, one of which is by using coal ash waste as a soil repairer to improve soil quality in post-mining land. This experiment was carried at the Faculty of Agriculture screenhouse, Winaya Mukti University, Tanjungsari, Sumedang Regency on the altitude of 850 M above sea level. The trial period is from Jully to August 2020. The experiment aims to determine the effect of comparisons of post-mining soil media composition with Faba fixer on the value of growth of Pueraria javanicum plants. The experimental design used was a randomized block design (RBD) which consisted of five treatments and was repeated five times. Treatment is the ratio of Fla Ash Bottom Ash soil repairer and post-mining soil with the following dosages; A = 100% post-mining soil, B = 25% Faba soil repairer + 75% post-mining soil, C = 50% Faba soil repairer + 50% post-mining soil, D = 75% Faba soil repairer + 25% post-mining soil, E = 100% Faba soil repairer. The results showed that treatment C (50% Faba soil repairer + 50% soil) had a good effect on plant height and shoot wet weight, treatment D (75% Faba soil repairer + 25% soil) had a good effect on the number of leaves, root length, number of effective nodules, and root wet weight of Pueraria javanicum plants.
