Abstract

The consumption of the coffee beverage generates large amounts of sludge that can be converted into organic compost when composted. It evaluated levels of composted coffee grounds in the production of carrots. The experiment was conducted at the Goiano Federal Institute - Campus Urutai, GO. A completely randomized design with 5 treatments was used: 0%, 25%, 50%, 75% and 100% of composted sludge and four replicates. The following parameters were evaluated: root length, plant height, MFR, root diameter, weight of (MSPA) and weight of (MSR). The results were analyzed using the SISVAR software, performed the analysis of variance and when significant differences were found the Tukey test was used to compare the averages, at 5%. The higher percentage of sludge provided greater development in most of the analyzed parameters. It was concluded that composite coffee grounds in the substrate, the plants showed good development, obtaining positive results.

Highlights

Coffee (Coffea sp.) Is one of the most important and valuable agribusiness raw materials in the world and one of the most consumed beverages (Ximenes, 2010)
Through composting, coffee grounds can be transformed into stabilized organic fertilizer called organic compost (SOUZA et al, 2001)
The aim of this study is to evaluate the use of organic fertilizer from coffee grounds compost in carrot cultivation

Summary

Introduction

Coffee (Coffea sp.) Is one of the most important and valuable agribusiness raw materials in the world and one of the most consumed beverages (Ximenes, 2010). The large production and consumption of coffee originates a huge amount of waste, which has not been identified as potential important by-products (CRUZ, 2015). These residues are diverse (pulp, rind, mucilage, waste water and in the process of extracting the coffee beverage an organic residue is still generated, the coffee grounds) and according to some authors have enormous potential for reuse due to their richness in nutrients and bioactive compounds (CRUZ, 2015). Through composting, coffee grounds can be transformed into stabilized organic fertilizer called organic compost (SOUZA et al, 2001).
