Abstract:
The present investigation was conducted at Horticultural Research Cum Instructional Farm, College of Agriculture, IGKV, Raipur, Chhattisgarh, during Kharif season of 2020-21. The experiment was laid out in Completely Randomized Design with three replication having 10 treatment combinations of different size of pots with six pots per treatments. The treatments consisted of ten different sizes of pots viz., 15 cm, 17 cm, 19 cm, 21 cm, 23 cm, 25 cm, 27 cm, 29 cm, 31 cm and 33 cm diameter pots. The results of the study indicated that growth parameters viz., plant height (128.67 cm), leaf length (29.53 cm), leaf breadth (11.00 cm), stem girth (2.70 cm) were obtained significantly maximum in treatment T₁₀ (33 cm diameter pots). Whereas, Flower parameters viz., days to flower bud emergence (69.17 days), days to opening of flower (82.17 days) was recorded significantly minimum with treatment T₁₀ (33 cm diameter pots). Similarly, the significantly maximum flower blooming period (22.42 days), number of flower plant^-1 (45.83), length of flower (6.63 cm), diameter of flower (5.42 cm), length of inflorescence (12.42 cm), width of inflorescence (7.43 cm), flower stalk length (25.87 cm), flowering duration (42.33 days) was recorded in treatment T₁₀ (33 cm diameter pots). Number of tillers plant^-1 (4.00) and number of leaves plant^-1 (55.00) was recorded significant in treatment T₆ (25 cm diameter pots), number of leaves tillers^-1 (20.14) was recorded significant in treatment T₅ (23 cm diameter pots), leaf area index (4.90) was recorded minimum in treatment T₄ (21 cm diameter pots). Therefore, among all the treatment T₁₀ (33 cm diameter pots) was found significantly superior in all over the treatments.
