Abstract

This study aimed to evaluate different proportions of organic compost and soil as a substrate for the guavira emergence and seedling formation under different protected environments, in the high Pantanal region of the state of Mato Grosso do Sul. The seeds were placed in polyethylene bags (15 x 25 centimeters) filled with four percentages of organic compost (0%, 20%, 80%, and 100% of total volume) mixed with soil. These substrates were tested in agro-nurseries covered with black screen and 50% thermo-reflecting shade cloths. The substrate with 20% soil and 80% organic compost and the black screen shade cloth promote the best performance in the seedling production.

Highlights

This study aimed to evaluate different proportions of organic compost and soil as a substrate for the guavira emergence and seedling formation under different protected environments, in the high Pantanal region of the state of Mato Grosso do Sul
This study aimed to evaluate different proportions of organic compost and soil as a substrate for the guavira [Campomanesia adamantium (Camb.) Berg] emergence and seedling formation under different protected environments from November of 2009 to April of 2010 at the Mato Grosso do Sul State University Unit in Aquidauana, Brazil
Taking into consideration the evaluation of the environments for the different substrates, it was verified that for substrates containing 100% of soil and 20% of soil, the seedlings grown in the black screen presented greater height, diameter, dry weight, and Dickson’s quality index (DQI) when compared to seedlings grown within the thermo-reflecting screen

Summary

Introduction

This study aimed to evaluate different proportions of organic compost and soil as a substrate for the guavira emergence and seedling formation under different protected environments, in the high Pantanal region of the state of Mato Grosso do Sul. For fruit plant such as passion fruit and papaya, the addition up to 21% of commercial organic compost mixed with soil produced seedlings with better quality (COSTA et al, 2010a, COSTA et al, 2011). This study aimed to evaluate different proportions of organic compost and soil as a substrate for the guavira [Campomanesia adamantium (Camb.) Berg] emergence and seedling formation under different protected environments from November of 2009 to April of 2010 at the Mato Grosso do Sul State University Unit in Aquidauana, Brazil.
