Application of Biourin and Mycorrhizal Fertilizers on the Dynamics of Available P, P Uptake, and Shallot (Allium ascalonicum L.) Yield in Vertisols

The aim of this study was to evaluate the effect application biourin fertilizer and Mycorrhizal Vesicles Arbuscula (MVA) dosage on P dynamics, uptake yield shallots in vertisols. This designed with a factorial design pattern basis randomized block (RBD). treatment tested concentration (B), four levels: B10: Concentration 10 ml.l-1 water, B20: 20 B30: 30 water B40: 40 water. second MVA dose levels, namely: M0: Without MVA, M10:10 g.plant-1, M20: g.plant-1 M30: g.plant-1. results showed that significantly affected dynamics available Vertisol. at absorption 15.07% increased shallot yields by 41.07%. best biofertilizer vertisols achieved able increase plant nutrient 152% 72.38% from without MVA.Keywords: biourin; dose; Shallot
