Standardize the optimum dosage of polymer for soybean (Glycine max L. Merril) seed quality

Abstract

An experiment was undertaken to standardize the optimum dosage of polymer (L-200 red) for seed coating in soybean cv. JS 335 with 11 treatments (1 to 10 ml) including control. The coated seeds were then used for analysis various seed quality parameters. From the present study it was observed that soybean seeds coated with red polymer at 5 ml per kg of seeds recorded significantly higher germination percentage (90.67%), speed of germination (42.33), peak value germination (37.47), shoot length (16.73 cm), root length (16.67 cm), seedling dry weight (415.0 mg), speed of germination (42.33) seedling vigour index-I (3027) and seedling vigour index-II (37618) compared to all other treatments and control (79.33%, 31.97, 30.50, 12.10, 12.98, 324.67, 1989 and 25753, respectively).
