Pumpkin was used as vegetables. They are used popularly in the meals or making drinks because pumpkin contains vitamins, fiber, mineral, protein, glucose and lipid. Besides, pumpkin is not only nourishing, but also is precious drugs to cure diseases. In this article, we analyzed some ingredients including heavy metals and NO3- in soil, water and pumpkin samples from households in Loc Thanh Village, Bao Lam District, Lam Dong Province (pumpkin of households grown by using chemical fertilizers and pesticides). These samples showed that some heavy metals such as Cu (Copper), Pb (Plumb), Cd (Cadmium) and As (Arsen) exceeded the allowable limits. However, the pumpkin samples that we grew by using organic fertilizers showed a significant reduction in heavy metal content, within the safety limit according to Vietnamese standards. Thus, the using organic farming methods has resulted in better quality products than using chemical fertilizers and pesticides.
