Abstract: The experiment was carried out at Horticultural Research Station, Mondouri, BCKV during the rabi (winter) season of two consecutive years i.e. 2009-10 and 2010-11. In both the years, big to medium size cloves cv. Katki were planted during middle of October, in 2.0 m x 1.5 m plots, at 20 x 15 cm spacing accommodating 100 plants per plot. The experiment with four levels of -1 -1 sulphur (0, 20, 40 and 60 kg ha ) and five levels of nitrogen (50, 100, 150, 200 and 250 kg ha ) was laid out in split plot design with 3 replications assigning sulphur levels in main plot and nitrogen levels in sub-plots.The maximum plant height (76.16 cm), leaf number (11.96), equatorial diameter (3.92 cm), and number of cloves per bulb (34.27) were observed with S N . But the plants 60 250 grown under S N interaction recorded widest leaf (1.52 cm), maximum polar diameter (3.67 cm), weight of bulb (33.68 g), yield 60 200 2 -1 per plot (3.00 kg per 3m ), projected yield (7.50 t ha ), maximum net return (Rs. 1,48,038/-) and B : C ratio (1.92). The minimum plant height (50.72 cm), leaf number (7.32), weight of bulb (19.15 g), projected yield (4.23 t/ha), net return (Rs. 52,736/-) and B:C -1 ratio (0.71) were observed under S N treatment. From yield maximization and B:C ratio point of view 60 kg S ha and 200 kg N 0 50 -1 -1 ha was found best when applied with 125 kg P O and 150 kg K O ha .
