Chemical analysis has been undertaken to investigate the nutrients compositions and the presence of residual pesticides from rice cultivated from converted-to-organic paddy fields in Lombok Island. The nutrients being investigated were macronutrients (carbohydrates, fat, and proteins), micronutrients (beta-carotene), metal ions, and minerals, whereas pesticides being investigated were organo-chlorides residues such as endrin, delta-BHC, dieldrin, etc. The chemical analysis results were compared to those from rice cultivated from conventional farming, which uses chemical pesticides. It was revealed that there is no difference in the nutrients compositions of rice produced from converted-to-organic paddy fields to those from conventional farming. Moreover, it was shown that both rice samples from converted-to-organic and conventional farming paddy fields have no detectable residual pesticides. This finding suggests that the absence of residual pesticides from rice samples does not necessarily correspond to the application of organic farming in the converted-to-organic land. There is not robust evidence that the application of organic alters the nutrient composition of rice. This result also underlines the need to further investigate the real benefits of organic rice farming products in terms of nutritional composition and safety.
