Substrato composto de diferentes solos, com bioprodutos e cama de frango: influencia no solo e no crescimento inicial de Allophylus edulis (A. ST.-HILL,. Cambes. & A. Juss)

Abstract

Allophylus edulis (cocum, Sapindaceae) is a Brazilian native plant, consumed in the Midwestern region for medicinal purposes, for the treatment of disorders related to oxidative stress such as diabetes; inflammations of the throat, intestinal and digestive problems. Its exploitation is exclusively in native areas. Based on this, the objective was to investigate the substrates best suited to the initial cocum growth. The experiment was conducted in a greenhouse under 50% sombrite. Combinations of substrate of the Haplorthox sandy soil type collected under Cerrado (LVdCer), under forest fragments of the Atlantic Forest (LVdMata), chicken manure, Penergetic K® and Fert-Bokashi® were tested, totaling nine substrates, with LVdCer ; LVdCer + Penergetic K® (P); LVdCer + Fert-Bokashi® (B); LVdCer + chicken manure (C); LVdCer + C + P; LVdCer + C + B; LVdMata; LVdMata + P; LVdMata + B. The design was randomized blocks with four replications. The experimental unit was composed of six vessels with one plant each. In the substrates with incorporated chicken manure there was an increase, on average, of 332.9% of P, 137% of Ca, 124% of Mg and 271% of Zn. The cultivars of cocum cultivated in LVdCer + C reached the highest SPAD index (53.52 at 180 days after transplanting, higher N content in the leaves (28 g kg -1) and higher IQD (0.42) on the substrates LVdCer + C, LVdCer + C + P and LVdCer + C + B, reached the highest SPAD, Fv / Fm, AP, DC, AF, AR, MSF, MSR, MSC, MFT, MST and IQD indexes indicating that the incorporation of chicken manure to the substrate, until the 180 days after the transplantio, provide better conditions for the cocum.
