Abstract:

Wheat is a major food material for Iranian people and more than half of the world population. Therefore study, development and increase of production efficiency about this crop is very important. Reducing amount of losses in harvesting stage is one of the methods that increase wheat production efficiency. For this reason, information about the rate and the origin of losses is necessary. In order to determining the losses rate, various methods has been produced and used by many institutions. The aim of this study is the comparison of three custom measurement methods in our country and suggesting the method which is the most accurate and feasible. This study was conduction in Pars Abad in agricultural education center of Moghan. The performance of design and evaluating the results conducted based on strip plat design with three replication and in three moisture levels including 12-13, 14-15, 16-18 percent and with three method of losses measurement consists of FMO, ministry of agriculture, institute of dry land research. The results showed that there are significant differences between three measurement methods in every three moisture levels. FMO method was more accurate than two other methods and the ministry of agriculture method indicated high more accurate than dry land research institute method. Moisture of 14-15% in wheat harvest time has been recognized the most optimum range due to having minimum
