Investigations were carried out to determine the most appropriate stage of harvesting and threshing method with minimal impact on seed quality characteristics of soybean seeds. The field experiment was conducted in „H‟ Block of seed unit in two factorial randomized complete block design (RCBD) in three replications with the different treatments of harvesting soybean pods at 90, 100 and 110 days after sowing (DAS) and the threshing of seed crop was done by three methods viz., Stick beating (T1), Tractor trampling (T2) and Mechanical thresher (T3) and storage experiment was conducted for a period of 180 days under the ambient conditions in Post Graduate laboratory of the Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad. The results revealed that among harvesting stages, soybean harvested at 90 DAS recorded the highest oil content ( %) and lowest protein content (). Delayed harvest viz., 100 DAS and 110 DAS resulted in increased protein and decreased moisture and oil content. Among threshing methods, beating with sticks proved superior for oil ( %), protein content ( %). During storage there was no significant difference in protein, oil and moisture content of seeds. Results obtained indicated that for good seed quality, soybean pods should be harvested at 90 DAS and threshed by beating with sticks and can be stored for long period without affecting protein and oil content. | Impact of stages of harvesting and threshing methods on moisture, protein and oil content of soybean [Glycine max (L.)
