Vegetable and soil samples were collected from four farms. Samples were also collected from a farm out of Ukat Nsit where there are no sand mining activities to serve as controls. The results revealed variable levels of the trace metals in the samples. In the soil, the metals levels ranged from 3.67 mg/kg Pb to 19.10 mg/kg Cu. In the vegetables, the trace metals levels ranged from 0.150 mg/kg Ni to 17.3 mg/kg Cu in L. africana and from 0.00 mg/kg Ni to 10.16 mg/kg Fe in T. occidentalis, respectively. Cd in the soil and vegetables exceeded the safe limits set by USEPA and WHO. The metal levels in the vegetables and soil from the control site were lower than those of the study area. This could be attributed to the negative impact of sand mining activities. Positive correlation at p < 0.01 was seen between Cd and Pb, Cd and Fe, Pb and Zn, As and Fe as well as Fe and Zn, indicating that Cr, Pb, Fe, Cu and Zn originated from the same anthropogenic sources. The target hazard quotient (THQ) for all the measured trace metals for the vegetables were lower than 1 (except Cd), indicating that the vegetables are relatively safe for consumption, except that their Cd levels could have adverse health effects.","PeriodicalId":7605,"journal":{"name":"American Journal of Applied Chemistry","volume":"506 1","pages":"135"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78224279","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}

Each year, shallot productivity in Indonesia is unstable due to nutrient degradation on agricultural land, therefore efforts are needed to increase the productivity of shallot. One of the solution is by using NPK fertilization. This experiment aims to determine the effect of NPK compound fertilizer on N total, N-uptake, and shallot bulb yield. This research conducted at the Soil Chemical and Plant Nutrition Experiments Field, Faculty of Agriculture, Padjadjaran University, Jatinangor, from February to June 2019. The experimental design using Randomized Block Design (RBD) consisted of one control treatment as a comparison, one N, P, K single fertilizer treatment (250 kg ha-1 Urea, 125 kg ha-1 ZA, 200 kg ha-1 SP-36, and 250 kg ha-1 KCl), and eight NPK compound fertilizer treatments of various doses with three replications. The results showed that the NPK compound treatment affected the total N, N uptake, and shallot bulbs yield. Treatment of 75% NPK compound (675 kg ha-1 ) obtained the highest results of fresh bulbs weight at 41.64 g clump-1 and dry bulbs weight at 25.27 g clump-1 .","PeriodicalId":7605,"journal":{"name":"American Journal of Applied Chemistry","volume":"1 1","pages":"152"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76005138","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}
