• Abstract:

  The baru - Dipteryx alata (Vogel)

  is a tree species typical of the cerrado biome

  and has been exploited for its nutritional and

  forage potential. The research consisted in

  cultivating baru seeds in different substrates

  for 180 days in order to verify that the substrate

  would promote better germination and seedling

  development of the plant, thus allowing a more

  efficient cultivation, contributing to the recovery

  of degraded areas. The methodology applied

  consisted in cultivating 25 seeds in sand with

  cattle manure (1: 1); 25 seeds on red soil with

  sand (1: 1); 25 with sand with bird manure (1:1) and 25 sand only, following the germination and seedling growth biweekly, verifying

  which of the substrates promoted the most efficient responses. The results indicated

  that the mixture of sand with bovine manure promoted a more significant growth,

  besides producing a larger number of leaves. The substrate containing bird manure

  did not promote the germination of any seed, this atypical condition occurred due to

  the presence of ants that degraded the seeds. Red soil development was slower. This

  shows that in order to obtain a more satisfactory result of the baru growth, we need a

  porous soil with a great concentration of organic matter for a more efficient result of the

  seedlings. New trials should be conducted to identify in detail which nutrients promote

  more efficient plant growth.
