摘要：An experiment was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh, during the period from October 2014 to March 2015 to study the effects of planting date and growth hormone on the growth and yield of cauliflower. The experiment consisted of two factors; Factor A: Three planting dates, such as P 1 : Planting on 1 November; P 2 : Planting on 15 November and P 3 : Planting on 1 December; Factor B: Four levels of Growth hormone, such as H 0 : No Hormone (control); H 1 : 10 ppm IAA (Indole-3 Acetic Acid); H 2 : 70 ppm GA 3 (Gibberellic Acid) and H 3 : 10 ppm IAA + 70 ppm GA 3 . The experiment was laid out following Randomized Complete Block Design (RCBD) with three replications. In case of planting date, the highest plant height (63.26 cm), number of leaves per plant (24.13), leaf length (59.26 cm), leaf breadth (19.31 cm) at harvest, curd diameter (22.25 cm), marketable yield per hectare (28.11 t ha -1 ) were recorded from P 2 and the lowest of those parameters were recorded from P 3 . In case of growth hormone the highest plant height (63.10 cm), number of leaves per plant (23.66), leaf length (59.05 cm), leaf breadth (18.98 cm) at harvest, curd diameter (22.39 cm), marketable yield per hectare (29.88 t ha -1 ) were recorded from H 3 and the lowest of those perameters were recorded from H 0 . Combination of planting date and growth hormone the highest plant height (65.96 cm), number of leaves per plant (26.42), leaf length (63.64 cm), leaf breadth (20.92 cm) at harvest, curd diameter (25.75 cm), marketable yield per hectare (31.03 t ha -1 ) were recorded from planting on 15 November and 10 ppm IAA with 70 ppm GA 3 (P 2 H 3 ) and the lowest parameters (21.75 t ha -1 ) were recorded from planting on 1 December and no hormone (P 3 H 0 ). It is apparent from the above results that the combination of planting on 15 November and 10 ppm IAA with 70 ppm GA 3 (P 2 H 3 ) was more productive from the other combinations. J. Environ.
