Abstract

Annual medics is a plant that is used for feeding domestic animals and as the green compost has an important role in strengthening lands and producing cattle feed.Medics' roots can stabilize nitrogen. This plant can planted alone or along with grains. If it is planted along with, it can be helpful in weed control. Because the production of annual medics'seed is difficult, design and construction of suitable,harvesting and threshing machines for seed production has top priority in research activity. In this study, physical properties of seven species of annual medics were determined. A series of tests were then conducted to determine the best threshing conditions. In these tests, effect of threshing clearance on germination, cleaning and separation efficiencies of seed were studied using a laboratory mill with plates of variable clearance. For this purpose, an experiment was conducted for two spicies of annual medics namely M.Scutellata and M.rigidula pods at three levels of threshing clearance and two levels of moisture content. The experiment followed a factorial design based on a completely randomizcd framework. It was found that the threshing clearance and seed moisture content affect the cleaning efficiency and seed separation. Surface in addition has a positive effect on germination percentage beacuse of stimulation of pods during thresing. Regarding cleaning efficiency, there is an interaction between threshing clearance and seed moisture content for M.rigidula. About the seeds' separation percentage from thresher, there was an interaction between threshing clearance and seed moisture content for M.Scutellata.Regarding germination, there was an interaction between threshing clearance and seed moisture content for M.Scutellata.The best threshing clearance is in the 3-3.5 mm range of M.Scutellata and 1.8-2 mm range for M.rigidula.This clearance is the same as seed width that was measured in the study of seed physical properties. The results of this research have an important role in design and construction of harvesting machinery and also on threshing of annual medics that is being conducted.
