Composting of coffee grounds and use of organic compost in growing carrots

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 Urutaí, 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.
