Abstract: A research study was conducted to determine the most appropriate stage of harvesting and the best 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 days after sowing (DAS), 100 DAS and 110 DAS and the threshing of seed was done by three methods viz., Stick beating (T1), Tractor trampling (T2) and Mechanical thresher (T3) and the seed quality was analyzed in the Post Graduate laboratory of the Department of Seed Science and Technology, University of Agricultural Sciences, Dharwad. The study revealed that among harvesting stages, soybean harvested at 90 DAS recorded highest germination (90.71%) and moisture (13.19%), vigour (2768) and lower mechanical damage (11.16%), EC (0.34 dS/m) as compared to other harvesting stages. Delaying harvesting viz., 100 DAS and 110 DAS resulted in increased seed leachates and mechanical damage. Among threshing methods, beating with sticks recorded less mechanical damage (10.16%) and maximum germination (92.70%), vigour (2850) and tractor trampling resulted in higher mechanical damage (15.71%), EC (0.38 dS/m) and minimum germination (85.65%) and vigour (2508). Results obtained indicated that for good seed quality, soybean pods should be harvested at 90 DAS and threshed by beating with sticks.
