Abstract

The objective of this work was to evaluate the effect of phosphorus doses in the growth of seedling of palm as well as to determine the content of macro and micronutrients from the below and above ground biomass through a tissue analysis. The assay was conducted in a greenhouse. The treatments were quantitative and equidistant, constituted by: T1- control (soil without P); T2-90 mg.dm-3; T3-180 mg.dm-3; T4-270 mg.dm-3; T5-360 mg.dm-3; T6-450 mg.dm-3; T7-540 mg.dm-3; T8-630 mg.dm-3; of P, respectively. 12 months after sowing, the following variables were evaluated: above ground height and biomass, below ground biomass and total. The nutritional analysis from below and above ground biomass was done to obtain the amount of macro and micronutrients. Results show that the growth of young palm plants was achieved to the analyzed parameters. Growth was obtained for height and it increased the aerial biomass of the plants to the doses of 540 mg.dm-3 of P, the answer was positive for the development of the below ground biomass to the doses of 450 mg dm-3, and the development of total biomass was reached with the doses of 540 mg.dm-3. For the macro tenors and micronutrients in the above ground biomass, the following sequence has been obtained, respectively: N> Ca> K> Mg> P>S; Fe> Mn> Zn> B> Cu, and for below ground: N> Ca> Mg> S> K> P; Fe> Mn> Zn> B> Cu, and the tenors of P didn't alter the tenors of nutrients in the plant.

Resumo

Este trabalho teve por objetivos avaliar o efeito de dosagens de fósforo no crescimento de mudas de palmiteiro, bem como determinar o teor de macro e micronutrientes do sistema radicial e aéreo dessa planta. O ensaio foi conduzido em casa de vegetação. Os tratamentos foram quantitativos e eqüidistantes, constituídos por: T1-testemunha solo sem adição de fósforo (P); T2-90 mg.kg-1; T3-180 mg; T4-270 mg.dm-3; T5-360mg dm-3; T6-450 mg.dm-3; T7-540 mg.dm-3; T8-630 mg.dm-3; de P respectivamente. Decorridos 12 meses da semeadura, foram avaliadas variáveis: altura e biomassa aérea, radicial e total, pela análise nutricional dos tecidos. Os resultados indicam que houve crescimento de plantas jovens de palmiteiro para todos os parâmetros avaliados. O crescimento em altura e o aumento da biomassa aérea das plantas jovens de palmito foram até a dosagem de 540 mg.dm-3 de fósforo. A resposta foi positiva para o desenvolvimento da biomassa radical até a dosagem de 450 mg.dm-3, sendo que o desenvolvimento de biomassa total foi alcançado com a dosagem de 540 mg.dm-3 de fósforo. Para os teores de macro na biomassa aérea obteve-se a seguinte seqüência, respectivamente: N > Ca > K > Mg > P>S; e micronutrientes Fe > Mn > Zn > B > Cu; e para radical: N > Ca > Mg > S > K > P; Fe > Mn > Zn > B > Cu, sendo que os teores de P não alteraram os teores de nutrientes na planta.
