Present investigation late kharif season same treatment A₇ recorded significantly highest plant height (73.19 cm), number of leaves (13.12), polar diameter (5.09 cm), equatorial diameter (5.05 cm) and lowest neck thickness (1.06 cm). The treatment B₄ among the concentration levels of SA recorded significantly highest plant height (71.10 cm), number of leaves (12.27), polar diameter (5.16 cm), equatorial diameter (5.11 cm).The interaction found non-significant effect on above growth parameters during late kharif the seasons. whereas during late kharif season highest significant average bulb weight (105.90 g), total bulb yield (32.84 t/ha), marketable bulb yield (30.19 t/ha). during late kharif season.

In overall the present investigation concluded that, foliar application of SA as 1^st spray of 250 mg/lit at 30 days after sowing in nursery stage, 2^nd spray, 3^rd spray and 4^th spray SA @ 250 mg /lit at 30,45 and 60 DAT was found beneficial for obtaining maximum yield improving quality and increasing yield of onion during late kharif season.
