MOREIRA, Adônis; HEINRICHS, Reges  e  PEREIRA, José Clério Rezende. Plants density on yield and nutrients concentration in leaves and fruits of banana cv. Thap Maeo. Rev. Bras. Frutic. [online]. 2007, vol.29, n.3, pp.626-631. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452007000300039.

This study aimed to evaluate the effect of plants density on yield, period of harvest and nutrients concentration in leaves and fruits of banana cv. Thap Maeo (AAB), cultivated in Manaus, State of Amazonas, Brazil. The experiment was conduced in a randomized blocks, with three replicates. Treatments were comprised of planting density (1,111; 1,667 and 3,333 plants ha-1), and two cycles of harvest (sub treatments). The results obtained from 1st cycle and 2nd cycle showed significant increase in the yield per unit area as the employed plant density increased. The shortest average period to harvest banana bunches (1st cycle, 338 days and 2nd cycle, 401 days) was observed for the lower density (1,111 plants ha-1). Pooled data of density and cycles showed that exportation of macronutrients through the fruits was, in order: K>N>P>Mg>Ca=S, while in micronutrients was: 1st cycle - Cl>Fe>Mn=B>Zn>Cu, and 2nd cycle - Cl>Fe>Zn>B=Mn>Cu.

Palavras-chave : Musa spp.; AAB; spacing; mineral nutrition; micronutrients; macronutrients.
