Implementação da metodologia 5S em um viveiro florestal na Região Dos Campos Gerais com ênfase no descarte de mudas das espécies de Eucalipto Tropical

Abstract

5S is an important and indispensable tool in companies. And in forest seedling nurseries it is no different. The increase in the disposal of seedlings prioritizes the use of improvement tools to minimize these losses. The objective of this work is to track 2 batches of seedlings of the tropical species urograndis, and have the number of losses within each batch and identify the reasons for discarding each material. Subsequently, implement the 5S methodology to minimize these discards, proposing alternatives/suggestions for process improvements. To analyze the number of seedlings discarded, percentage analysis and analysis of variance were carried out together with the average, minimum and maximum values of the number of seedlings discarded from materials 1 and 2. Statistical analyzes were carried out with the aid of spreadsheet and the Statistical Analysis System SAS® OnDemand for Academics software, free version. When analyzing the data, it was found that in general, material 2 presented a greater amount of losses when compared to material 1. Through the shade house and patio stage (first selection), when analyzing the variables, it is possible to affirm that there was a difference between clones. Oidium spp., Botrytis cinerea and the Black Cinnamon disease, caused by fungi of the genus Cylindrocladium spp., presence of calluses, fungi, exposed root, no root and rustification, were the reasons for discarding seedlings. The suggested solution to minimize these losses at each stage of the nursery is the use of a cleaning plan per area, fungi are often related to lack of cleaning and hygiene. And the 5S methodology implemented with the nursery team generated gains such as: Team engagement; improvement of the work environment in relation to organization and cleanliness; Standardization of environments; Combating waste, among others. It was possible to have a targeted approach, through suggestions for improvement, of what could be improved in relation to each stage of the nursery, according to each sense.
