Diagnosis of leaf nutrient content for ‘common’ arrowroot plants fertilized with ovine manure

Despite arrowroot’s (Maranta arundinaceae L.) appeal in several industry sectors, which indicates high potential for large-scale production, few studies have investigated the nutritional status of this crop species. Given economic relevance and limited data literature, objective work was to evaluate nutritive effect ovine biofertilizer cultivation arrowroot ‘comum’, two evaluation periods 180 272 days after planting (DAP). The experiment laid out as a split-plot randomized complete block design with four replicates. Leaf contents nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), boron (B), sodium (Na) were determined. High K Na observed leaves. sheep is suitable meet needs ‘common’. continuous application provided higher levels nutrients at planting.
