The experiment was conducted at “Nabagram Farmhouse”, Mannan Nagar in Noakhali, Bangladesh during the period from September 2018 to January 2019. The purpose of this study to evaluate the growth and yield of different varieties of cauliflower [Brassica oleracea var. botrytis L.] by the effect of different age of seedlings. The two factor experiment (7 treatments) were laid out in Randomized Complete Block Design (RCBD) with three replications where the unit plot size was 9 m² and spacing was 45 cm × 60 cm for plant to plant and row to row respectively. Factor: A: three varieties viz., T1= Snow crown, T2= Early shoot and T3= Silver cup 65 and Factor: B: different aged seedlings viz., T4 = 18 days old seedlings, T5 = 28 days old seedlings, T6 = 38 days old seedlings and T7 = 48 days old seedlings. Plant height (cm), number of leaves, curd initiation (DAT), curd harvesting (DAT), curd weight (kg) and curd yield (t/ha) were taken as parameters on the growth and yield of the plant. The findings of the experiment indicated that among the different varieties the highest yield can be obtained from T3 =25.54 t/ha in comparison with T1= 24.34 t/ha. In case of seedling ages, T5 (28 days old seedlings) gives highest growth and yield (26.39 t/ha) whereas the lowest yield (17.00 t/ha) was obtained from T7 (48 days old seedlings). In combined T5 (28 days) old seedlings of Silver cup 65(T3) produced highest yield (26.13 t/ha) in comparison with others treatment combinations. It could be concluded that planting Silver cup 65 F1 (T3) genotype at 38days (T6) old seedling recorded the highest growth values 19.78 cm meanwhile planting the same genotype at 18 days (T4) evaluated the lowest 7.27 cm.
