| The mechanical harvesting is an important stage in the production process of soybeans and, in this process; the loss of a significant number of grains is common. Despite the existence of mechanisms to monitor these losses, it is still essential to use sampling methods to quantify them. Assuming that the size of the sample area affects the reliability and variability between samples in quantifying losses, this paper aimed to analyze the variability and feasibility of using different sizes of sample area (1, 2 and 3 m²) in quantifying losses in the mechanical harvesting of soybeans. Were sampled 36 sites and the cutting losses, losses by other mechanisms of the combine and total losses were evaluated, as well as the water content in seeds, straw distribution... |

| Wheat is one of the most important food staff in consumption pattern of each country. More than 50% of human energy is supplied from bread in developing countries. Reducing of losses and waists in combine harvesting resulte increasing considerable wheat production in country. Combine loss is less than 2%-3% in developed countries, while that of developing countries is about 15%-20% in different regions and circumstances of harvesting seasons and field conditions. Regarding to research finding that maximum total combine losses are related to combine header loss, so it is necessary to determine precise losses and their causes to improve and modify existing combine's technical characteristics. In this national research project that took place in three... |
