A field experiment was conducted at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Jaipur) during Rabi season 2014-15 on loamy sand soil. The experiment consisting 16 treatment combinations i.e. four levels of each sulphur (0 kg, 20 kg, 40 kg and 60 kg sulphur ha-1) and spacing (30x20 cm, 30x30 cm, 45x30 cm and 45x45 cm) tested in randomized block design with three replications. Results revealed that application of 60 kg sulphur ha-1with 45x45 cm spacing to the knol-khol crop significantly increased the plant height (cm)at harvest, days taken to initiation of knob, days taken to marketable maturity of knob, diameter of knoband volume of knob as compared to control, 20 kg sulphur ha-1 and 30x20 cm and 30x30 cm spacing but statistically at par with 40 kg sulphur ha-1 and 45x30 cm spacing, whereas number of leaves per plant, chlorophyll content (mg/g) in leaves, fresh weight of leaves and knob per plant (g) and Knob: leaf ratio were found significantly maximum at 40 kg sulphur ha-1 and 45x30 cm spacing as compared to control, 20 kg sulphur ha-1 and 30x20 cm and 30x30 cm spacing being statistically at par with 60 kg sulphur ha-1 and 45x45 cm spacing. The combined application of 40 kg sulphur ha-1 with 45x30 cm spacing proved to be most superior treatment combination in terms of diameter of knob and volume of knob, whereas 40 kg sulphur ha-1 with 30x30 cm spacing in terms of total knob yield (q ha-1). In case of plant height at 30 DAT, sulphur and spacing levels was found to be non significant.
