Abstract

ABSTRACTThe objective of this study was to test the hypothesis that biochar, applied with cattle manure, promotes better development of seedlings of Magonia pubescens St. Hil. The experiment was conducted at the State University of Mato Grosso, Nova Xavantina, Brazil, in 2011. We used a completely randomized design, with twelve treatments and three replications. The substrates formed by the higher levels of cattle manure plus biochar (30%) provided better results of height, diameter and aerial biomass. However, the Dickson Quality Index has not confirmed the quality of seedlings in these treatments. We also observed that the doses of biochar (20 and 30%) when added separately to the Latosol, are not efficient for the growth improvement of the seedlings. Based on the present results, we validate the hypothesis that substrates formed with a mixture of cattle manure and biochar are effective to improve the production of seedlings of M. pubescens.

Highlights

Brazil has the world’s greatest biological diversity, with six different biomes over its large territorial extension (SOUZA; FELFILI, 2006)
According to Artur et al (2007), the need for reforestation has increased the demand of native forest species seedlings, as, in addition to the economic and environmental potential, their propagation out of natural conditions is a feasible process to cover for such increase (MELO et al, 1998)
Hil, has great commercial use potential, as it may be applied to different activities, as civil construction, furniture manufacturing and coal production (ALMEIDA et al, 1998), besides the pharmacological use (SOUZA; FELFILI, 2006)

Summary

Introduction

Brazil has the world’s greatest biological diversity, with six different biomes over its large territorial extension (SOUZA; FELFILI, 2006). Among the native forest species of Cerrado, Magonia pubescens St. Hil (tingui), has great commercial use potential, as it may be applied to different activities, as civil construction, furniture manufacturing and coal production (ALMEIDA et al, 1998), besides the pharmacological use (SOUZA; FELFILI, 2006). The tree serves as decorative plant, due to the lace-like aspect of its leafs, and is an excellent option for planting in degraded areas, especially those of permanent preservation (MACEDO et al, 2009). This species represents an alternative for both environmental recovery and commercial cultivations
