http://dx.doi.org/10.5902/1980509816615Noni fruit has been used since antiquity for treatment of many diseases such as allergy, arthritis, asthma, cancer, depression, diabetes, digestion, hypertension, and insomnia and is used as food supplement. Although these properties and its intercontinental adaptability, information about nutrient exigency and crop management is still little frequent in international and national literature. In this direction an experiment was carried out, during the period of July/2009 to July/2010, in São Luis, Maranhão state, Brazil, in order to evaluate effects of manure and potassium fertilization of the soil on mineral composition in leaves dry matter of noni plants. The treatments were arranged in randomized blocks 2 x 4 referring to absence and presence potassium fertilization (130 kg ha-1 K2O)  in soil with bovine manure levels (0, 1.7, 6.6 e  11.6 kg plant-1) applied in the area of plant projection . From the results, except in calcium and magnesium, the interaction bovine manure x K2O proportioned increment on the content of other macro and micronutrients in dry matter leaf of noni plants. The establishment of levels interpreting nutrient content suitable for noni is needed to assist the discussions of future studies of fertilization and crop nutrition.
