摘要

This study evaluated nutrient accumulation of yellow passion fruit seedlings produced in substrates containing proportions of decomposed buriti (Mauritia vinifera Mart.) stem (DBS) and the boron in this process. Four experiments were conducted in Federal University of Piaui in Brazil. The experimental design was completely randomized in factorial scheme 6 x 2 + 1, referring to the substrates [DBS (100%), soil and sand 1:1 (20%) + DBS (80%), soil and sand 1:1 (40%) + DBS (60%), soil and sand 1:1 (60%) + DBS (40%), soil and sand 1:1 (80%) + DBS (20%), commercial substrate (additional treatment without boron) and soil, sand and manure 1:1:2] with (0.5mg B.dm(-3)) and without boron. The following variables were recorded: total nitrogen, total phosphorus, potassium, calcium and magnesium, boron, absorption efficiency index and chlorophyll. No influence concerning the substrate composition was noticed on nutritional status, but boron influenced on K and Mg of yellow passion fruit seedlings.
