Abstract

FONTES, Patrícia Soares Furno et al. Evaluation of the nutricional status and development of banana cultivar "prata anã" (Musa spp.) in relation to nitrogen fertilization. Rev. Bras. Frutic. [online]. 2003, vol.25, n.1, pp.156-159. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452003000100043.

The experiment was carried in Yellow Podzolic at Itaocara, Rio de Janeiro State, Brazil, (Latitude 21º 39' 12" South and Longitude 42º 04' 36" West, with climate, conform Köppen, classified as Awi,), to evaluate the nutritional status and the development of the banana cultivar "Prata Anã" in relation to five nitrogen fertilization levels (0, 150, 300, 450 and 600 kg ha-1 year-1 of N). In general, the analyzed nutrients contents in the leaf dry matter were not modified by the increase of N dosage, being exception Mn and Cl. The levels of leaf nutrients differed between sampling seasons, with the exception of Ca. There was no variation in the levels of N in the leaf dry matter, in relation to nitrogen fertilization. Lower levels of K were observed in the leaf dry matter during the blooming and bunch development. In the first growing cycle, the nitrogen fertilization had no effect either on blooming time or in the bunch height. There was a decrease in the number of offshoots with the increasing of N levels.

Keywords : banana; Musa; fertilization; nitrogen; leaf nutrient status; urea.
