Quantification and risks of Cd, Cu, Pb, Zn, Ni, Fe, As and Cr were assayed in two vegetables (Lasianthera africana and Telfairia occidentalis) obtained from the sand mining environment of Ukat Nsit. 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.

Shallot (Allium ascalonicum L.) is a horticulture commodity that has a lot of benefits also prospective regarding its increasing demand. 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 .
葱(Allium ascalonicum L.)是一种具有许多效益的园艺商品，其需求日益增长，前景广阔。由于农业用地的养分退化，印尼每年的大葱产量都不稳定，因此需要努力提高大葱的产量。解决方法之一是施用氮磷钾。本试验旨在确定氮磷钾复合肥对青葱全氮、氮素吸收和鳞茎产量的影响。该研究于2019年2月至6月在贾蒂南戈尔市帕迪加兰大学农学院土壤化学和植物营养实验场进行。采用随机区组设计(RBD)，试验设计为1个对照处理、1个N、P、K单肥处理(250 kg ha-1尿素、125 kg ha-1 ZA、200 kg ha-1 SP-36和250 kg ha-1 KCl)和8个不同剂量的氮磷钾复合肥处理，3个重复。结果表明，氮磷钾复合处理影响了青葱总氮、氮素吸收量和鳞茎产量。75%氮磷钾(675 kg hm -1)处理的鲜球质量最高，为41.64 g，干球质量最高，为25.27 g。
