The influence of seed processing and storage on seed quality parameters were evaluated in soybean var. DSb-21 using different sieve size in seed grader followed by different machine combinations. The study revealed that graded seeds obtained from the sieve 3.75 mm followed by spiral separator recorded the higher recovery (95.25%), germination (88.33% and 68.33%), and vigour index (3502 and 1317) during initial and at ten months of storage period respectively. Seed processed through seed grader recorded higher recovery but lower in seed quality parameters. Seeds obtained from spiral separator after processing through seed grader followed by specific gravity separator has recorded higher seed quality parameters but lowest recovery per cent. Irrespective of processing methods followed, size graded seeds with 3.75 mm sieve maintained seed quality for more than eight months compare to seeds graded with 4.00 mm and 4.80 mm sieves. Processing of soybean seeds with seed grader followed by spiral separator can be recommended as it results in higher recovery with good seed quality parameters and the seeds maintained viability up to nine months of storage. Hence, grading soybean var. DSb-21 with 3.75 mm sieve is more effective and economical than presently recommended 4.0 mm sieve.
