Combining Fully Acidulated Phosphates with Phosphate-Solubilizing Microorganisms for Urochloa brizantha Fertilization

Aimed to evaluate the productive, morphological and nutritional characteristics, in addition accumulation of nutrients aerial part Urochloa brizantha cv. Marandu subjected phosphorus chemical sources its interaction with phosphate-solubilizing inoculant. The experiment was developed Colorado do Oeste, RO, Brazil, being adopted a randomized block design three replications. treatments consisted different phosphate fertilizer doses associated or not microorganisms (PSM): 0% P; 50% 100% P + 250 mL ha-1 PSM; 500 750 1000 PSM. Triple superphosphate used as fertilizer, fertilization PSM occurred on November 19th, 2021. results for characteristics yields grass showed significant differences. arrangements influenced green matter yield dry yield, both using presented higher (3,642.75 kg 1,049.10 ha-1, respectively). Higher crop growth rate were also found when employing combination Dry had effect bromatological composition, observed alone (34.55%). Regarding part, highest utilizing P, resulting an 15.4 ha-1. Inoculation U. does have adverse effects increase availability plant, adequate development productive potential area.
