Abstract:
College of Forestry, VCSG Uttarakhand University of Horticulture & Forestry, Ranichauri(Uttarakhand An experiment was designed to find out the influence of different doses of zinc and sulphur on seed quality of Indian mustard variety Urvashi. The field experiment and laboratory experiment was conducted in Split Plot Design with three replications during 2011-12 & 2012-13 at New Dairy Farm, Kalyanpur, Kanpur and Seed Testing Laboratory of Department of Seed Science and Technology, Respectively. Six doses of zinc and sulphur viz. 0.0, 2.5, 5.0, 7.5, 10.0, 12.5 Kg ha-1 and 0, 10, 20, 30, 40, 50 Kg ha^-1, respectively were applied as basal dose. Observations were recorded on seed quality parameters. Results showed that the application of zinc and sulphur affected significantly to all parameters. The dose 10 Kg Zn ha-1 & 50 Kg S ha^-1 recorded highest seed germination (91.16 & 91.19%), seedling length (13.54 & 13.47 cm), seedling vigour index (1230.73 & 1225.46), oil content (39.92 & 39.67%), linolenic acid (15.51 & 15.06%), linoleic acid (21.15 & 22.79%), oleic acid (13.89 & 14.30%) and palmatic + stearic acid (2.96 & 3.06%) and lowest amout recorded in erucic acid and eicosenoic acid. The application of 10.0 kg Zn ha-1 and 40 Kg S ha^-1 increased days to maturity (134.64 & 135.08) and 1000-seed weight (5.30 & 5.72 g) was recorded in 7.5 Kg Zn ha^-1 and 50 Kg S ha^-1, respectively. However, rest of the characters was affected by the application of zinc and sulphur.
