A field experiment and laboratory experiment was conducted in Split Plot Design with three replications during 2011-12 & 2012-13 on Indian mustard variety Urvashi 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 morpho-physiological characters. 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 leaf area index at 30 DAS (0.65 & 0.68), 60 DAS (1.97 & 2.04) & 90 DAS (1.64 & 1.73), chlorophyll intensity at pre-flowering (47.19 & 48.75%). Like-wise, 12.5 kg Zn and 50 Kg S ha-1 had registered maximum chlorophyll intensity at post-flowering (40.73 & 41.21%), canopy temperature depression at pre-flowering (4.93 & 5.070C) and post-flowering (4.31 & 4.320C), respectively. The interaction zinc and sulphur did not show significant effect on leaf area index at all stages. However, rest of the characters was affected by the application of zinc and sulphur.
