Initial growth of Dalbergia nigra (Vell.) Allemão ex Benth influenced by the use of inoculants and current land uses

ABSTRACT

The study aimed to evaluate the effectiveness of inoculation on the initial growth of Dalbergia nigra in soils from different land use systems. For this, the inoculant BR 8404 was applied to soil samples collected from different management systems, combined or not with mineral fertilisers. Based on the Dickson Quality Index (DQI), it was observed that the inoculant can replace the use of mineral nitrogen fertiliser for the cultivation of Dalbergia nigra seedlings, except in pasture soil. The soil from angico planting was the most suitable, presenting the best responses in the analysed variables, indicating its suitability for the initial growth of D. nigra seedlings.
