“…These technologies collect data at regular intervals and present them to the operator in real-time. Furthermore, data can be extracted for external storage and analyzed through control charts, which is a statistical method to monitor data variability (such as header height, ground speed, and engine speed) and ensure operational quality (Lima et al, 2017). The low number of observations of these embedded technologies can be attributed to the prevalence of old combine harvesters, as well as a potential negligence in utilizing embedded systems even in studies involving newer models.…”

Grain losses pose a threat to agricultural sustainability, particularly in developing countries. Mechanized harvesting is a key process in which losses occur; thus, its investigation is essential. Therefore, a systematic and meta-analytical review was conducted to encompass studies on quantitative soybean losses during harvesting in South America from the last two decades. The initial search yielded 1,094 scientific articles; however, only 25 studies met the inclusion criteria. This study provides an overview of technical aspects monitored on farms, guidelines to ensure efficient harvesting and literature gaps for further innovations. Because studies on soybean losses were predominantly based on continuous observational data and lacked methodological quality according to a quality scoring, only four studies were included in the meta-analysis. The meta-analysis results showed a significant relation between losses and the combine age, indicating that combines with over 10 years of use result in higher losses than newer ones (p ≤ 0.05). Conversely, operating at speeds exceeding 5 km h-1 did not lead to significant increases in soybean losses (p > 0.05). Many decisions can be taken at the farm-level to reduce losses, such as proper training of workers and adequation of combine harvesters according to each crop condition. The insights described here are timely for paving the way towards innovation in harvesting systems and minimizing grain losses by understanding the critical points within the context improving yields during soybean harvesting.

“…At the harvesting and distribution stage, harvesting and processing by mechanical means to minimize loss and reduce cost is critical [36,37]. Harvested seeds are authenticated by various accredited technicians and labs, and they need to be certified/labeled based on their destination for the domestic/international markets.…”

Soybean is an important and valuable crop for global food and feed supply, providing high-quality nutrition. Globally, five countries—namely Brazil, the USA, Argentina, China and India—have dominated soybean production for many years. The intention of this paper is to review the reasons for their dominance, starting with seeds. High-quality seeds enable stress-free, high-density and even planting of soybean in the field. Seed quality assurance is essential for the successful expansion of soybean cultivation. The aim of this review is to compare and contrast the factors impacting soybean seed production in these top five soybean-producing countries, including the situations at different stages of the supply chain; research and development on new soybean varieties; and regulations, rules and quality assurance systems (seed testing, certification and labeling). Since the soybean supply chain involves many different operating parties, principles and practices, efforts on different fronts need to be well coordinated by a central authority to ensure successful production. Recently, China has implemented a revised national “Seed Law”. The possible impacts of this new legal framework on soybean seed development and trading in China are also discussed. The strengthened China Seed law to protect resources and encourage variety innovation, as well as the clearer China GM soybean commercial release policy, implies future soybean cultivation expansion with elite varieties. A continuous global production increase will require every party’s compliance to the sustainability principles.

To automate the process of harvesting crops, different types of harvesting machines are required. The most common type of machines used to automate ingathering are harvesters. The use of harvesters for collecting grain crops is rational in fields from 2 hectares. On smaller areas it is not profitable and difficult to apply. For applications in small areas, low-capacity harvesters with a throughput of the thresher up to 1 kg/s (small-sized) may be suitable. The purpose of this study is to analyze the cushioning mass control system of a low-capacity unmanned combine harvester using computer simulation, as well as the simulation of directional stability and turning. To calculate vertical vibrations in the Matlab/Simulink software package, a model of a cushioning system for a wheeled agricultural combine was prepared. In the same software package, simulation of directional stability and turning implementation was carried out. The parameters of vibration displacement, vibration velocity and acceleration, as well as the vibration frequency indicators on the operator's seat are determined. Comparison of the simulation results of the initial and corrected direction of movement of the harvester showed that for this model the maximum deviation from the planned path is a maximum of 10%, which is within acceptable limits. The maximum deviation of the harvester from the course does not exceed the permissible values, which is acceptable accuracy to ensure directional stability.
