The main goal of this works was evaluate the effect of nitrogen and boron doses, in the rootstocks ‘umbu’ (Spondias tuberosa Arruda Câmara). The experiment it was led at CCA/UFPB-Campus II, located in the Areia city, state of Paraiba in Brazil. The treatments were five levels of nitrogen (0 to 4,50 g dm-3) as ureia (45% N), and five boron doses (0 to 3,0 mg dm-3), as borax (11% B), applied in the subtract constituted by the mixture of 75% of soil and 25% of manure bovine, in the randomized blocks design, with four repetitions. The experimental unit was constituted of three recipient containing three seedlings. It was evaluated height and the diameter of the stem of the seedlings, besides the mass of the matter evaporates and the areas of the root system and aerial part. The increase of the levels of nitrogen resulted in smaller growth of the seedlings. The application of 3 mg dm-3 of the boron provided the largest growth of the aerial parts and root.Key-words: Spondias tuberosa, mixture, fertilization. |
