Abstract:
A laboratory study was conducted during 2015-16 and 2016-17 at seed unit laboratory, UAS, Raichur to find out the cultivars response in terms of seedling vigour and biochemical activities to assess the suitable planting dates for quality seed production. In order to explain the effect of sowing date on soybean (Glycine max L. Merrill) seed quality parameter, two varieties including JS 335 and DSb 21 were sown from Nov 1st fortnight, Nov 2nd fortnight, Dec 1st fortnight, Dec 2nd fortnight, Jan 1st fortnight, Jan 2nd fortnight, Feb 1st fortnight, Feb 2nd fortnight. The results of the experiment revealed that the below parameters significantly affected by sowing dates. The highest germination percentage (91.25%), shoot length (21.32 cm), root length (20.17 cm), seedling length (41.49 cm), seedling dry weight (121.23 mg), peak value of germination (39.83), alpha amylase activity (25.20 mm), Dehydrogenase activity (1.1.05 OD value), electrical conductivity (0.486 dSm-1), seedling vigour index- I (3789) and seedling vigour index- II (11065) were recorded for crop sown in Nov 1st fortnight. It was noticed that sowing date significantly affected the seed quality parameters and seeds from early sowings (Nov 1st fortnight sowing) had the good seed quality.
