Results of the field experiment entitled “Impact of Cauliflower (Brassica oleracea var. botrytis) varieties for growth and yield characters by different sowing dates” conducted at the Guru Kashi University Research Farm during the rabi season of the year 2022. The objective was to evaluate the effect of two planting dates (8th September and 23rd October) on growth and yield attributes of ten varieties Kanchan, Noval, Golden 1100, Pusa snowball, Syngenta lucky,PSC666, Syngenta jasska, Shubhra, Joti-2 and Selection-1. The field experiment was laid out in randomized complete block design (RCBD) with three replications. Significantly maximum breadth of leaf 24.23 cm with sowing date 8th September and leaf breadth 22.67 cm with sowing date 23rd October in Syngenta lucky. Polar diameter was 16.57 cm (8th September) and was 17.34 cm (23rd October) maximum in Golden 1100. Maximum plant height (28.69 cm) and number of leaves (24.45) was recorded from Selection-1 variety; the highest leaf length (42.17 cm), equatorial diameter (27.15) and minimum days to harvest (91.16days) in Joti-2 variety; maximum weight without folded leaves (825.09gm), maximum curd yield/plot 36.53 kg and maximum total yield 610.21 (q/ha) was recorded in Syngenta Jasska when crop was sown date 8th September. The maximum plant height was 28.57 cm, maximum equatorial diameter 25.37 cm, maximum 40.35 cm leaf length and minimum days to harvest 90.16 was recorded in Joti-2 variety; the number of leaves significantly maximum shown by Pusa snowball (22.34), significantly maximum fresh weight of curd 821.45gm, maximum curd yield/plot 35.67kg and maximum total yield 608.34 (q/ha) was recorded in Syngenta Jasska when crop was sown on 23rd October. The combined effect of sowing dates and varieties showed that sowing on 8th September Joti-2 variety performed well in growth contributing characters and Syngenta Jasska was found to be the best in yield parameters from all other varieties.
