Effects on vam fungi and phosphorus on the nutrition of rangpur lime after transplanting

Abstract

The objective of this study was to verify the effects of VAM fungi inoculation and sources and doses of phosphorus on the nutrients amounts of Rangpur Lime, after transplanting. The experimental design was a complete randomized block in a 3 x 2 x 4 factorial design with three replications: three inoculation conditions (Glomus clarun, Acaulospora morrowae and the control); two sources of phosphorus and four amounts from each. Mycorrhizal fungi did not affect nutrients uptake by the plant. Simple superphosphate showed to be superior than Araxá apatite concerning only to Ca uptake, increasing it 9.3% in the plant dry matter. Increasing doses of P₂O₅ reduced the amounts of B and Zn by 9.64% and 18.80%, respectively.
