Abstract

Abstract: Soybean is a crop of great economic relevance in the world, with seed production being one of the most important sectors of its agro-industrial complex. Processing is one of the final stages of the seeds production process, it aims to remove impurities, select seeds by shape, size and density and pack properly. Monitoring and quality control at different stages of the process ensures that seeds meet storage and market standards. The aim of this study was to evaluate the different stages of processing in the physical and physiological performance of three cultivars of soybean seeds using statistical process control tools. The work was carried out at the seed processing unit with the cultivars M8644 IPRO, M8349 IPRO and M8808 IPRO, with sampling at eight points throughout the process. Water content, physical purity, germination, first count, accelerated aging, tetrazolium (vigor and viability), mechanical damage and electrical conductivity were evaluated. During the process, mean and amplitude control charts were used for each test. The use of control charts made it possible to monitor the process of soybean seed processing, pointing out the methodology as a tool to determine existing problems, to promote continuous improvement in the performance of seed processing.

Highlights

The production of high-quality soybean seeds involves the adoption of technology and adequate management in all stages
The maximum physiological potential of the seed is collected in the field, but the harvest and post-harvest processes can contribute to the reduction of its performance
Five 1 kg subsamples were collected at each stage, to form a sample composed of the same weight and its duplicate, packed in a paper bag (Brasil, 2009)

Summary

Introduction

The production of high-quality soybean seeds involves the adoption of technology and adequate management in all stages. The choice of cultivars with high productivity potential is important to guarantee an adequate stand and uniformity of plants These characteristics, associated with seed vigor, measured by high germination, and uniform seedling emergence in less time, under adverse conditions (Ebone et al, 2019) guarantee the success of the agroindustrial enterprise. In the search for high seed quality, processing is essential, as it removes the inert fraction from the lot, and classifies it by size, shape and density. This process improves these characteristics using homogenization and contribution with the improvement of the physical and physiological quality of the seed (Kirchner et al, 2014; Conrad et al, 2017; Amaral et al, 2018)
