Investigating the economic loss of dryland wheat losses during the production process in the seed production fields inside the research stations

it was tried to identify and rank the factors affecting dry wheat losses using the analytical hierarchical process, and the amount of losses of dry wheat during the production process was measured and the economic loss caused by it was evaluated, and finally, based on the identified factors,, at the Maragheh research station in 2020-2021 and 2021-2022 , the fields where wheat was cultivated in different stages of production were sampled in the form of proportional random sampling and their economic value was calculated. To determine the most important factors affecting damage, a paired comparison questionnaire was used, which was completed by experts in this field. Excel and Expert Choice software were used for data analysis. The results showed that every year, on average, 1.12% of wheat in each hectare is in the form of natural fall, 2.46% in the harvesting stage by the combine machine and 1.32% in the form of solid foreign materials, weeds and straw from the cycle. The consumption of human feed is removed and 8.95% is in the form of broken grains, which is consumed by livestock and poultry. In total, 13.84% equivalent to 233 kg/hectare of wheat is removed from the human consumption cycle as waste. Also, the results of the hierarchical analysis process This amount of waste is equivalent to the product produced on an area of about 1387 square meters. If each kilogram of this amount of waste is worth about 160,000 Rials, the resulting damage will be 37,280000 Rials per hectare.
