Teores foliares de nutrientes em plantas de camucamuzeiro (Myrciaria dubia (H.B.K.) McVaugh) submetidas a aduba es organica, mineral e foliar Nutrients leaf contents of Myrciaria dubia (H.B.K.) McVaugh plants submitted to organic, foliar and mineral fertilization

O objetivo neste estudo foi avaliar a resposta das plantas de camu-camu (Myrciaria dubia (H.B.K.) McVaugh) por meio dos teores foliares de macro (Ca, Mg, P, K e N) e micronutrientes (Fe, Mn e Zn), em um experimento conduzido na Comunidade do Brasileirinho, localizada na periferia do município de Manaus-AM. O delineamento utilizado foi em blocos casualizados, em esquema fatorial de parcela subdividida 3 x 10 (três épocas de coleta e dez tratamentos, com três repeti es). Os tratamentos foram constituídos por aduba o organica (1L de esterco de galinha), aduba o mineral, combina o de aduba o mineral e foliar e somente aduba o foliar. A aduba o organica resultou em maiores teores e Ca, Mg e K nas folhas dos camucamuzeiros e as plantas que receberam aduba o foliar apresentaram os maiores teores de Fe, Zn e P. The objective of this research was to evaluate the response of “camu-camu” plants (Myrciaria dubia (H.B.K.) McVaugh) through the analysis of macro (Ca, Mg, P, K and N) and micronutrients (Fe, Mn e Zn) leaf contents. The experiment was carried out in the Brasileirinho Agricultural Community, Manaus, Amazonas, Brazil. The experimental design was made in randomized blocks with a 3 x 10 split plot scheme with three sampling periods and ten treatments, with three replications. Treatments consisted of organic (1L of chicken manure), mineral and foliar fertilization, and a combination between mineral and foliar fertilization. Plants that received the treatments with organic fertilization presented the highest contents of Ca, Mg and K. The plants that received the treatments with foliar fertilization presented the highest Fe, Zn and P contents
