An experiment was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh, during the period from October 2014 to February 2015 to study the effects of cow dung and boron on growth and yield of broccoli. The experiment consisted of two factors; Factor A: cow dung -4 levels such as C0: no cow dung (control), C1: cow dung 10 ton/ha, C2: cow dung 15 ton/ha and C3: cow dung 20 ton/ha. Factor B: boron -4 levels, such as B0-no boron (control), B1: boron 1 kg/ha, B2: boron

In case of cow dung the maximum plant height at 60 DAT (61.47 cm), spread of plant at 60 DAT (50.00 cm), number of leaves per plant at 60 DAT (11.39), length of the largest leaf at 60 DAT (57.69 cm), primary curd weight (374.58 g), yield per hectare (15.74 t/ha) were recorded from C3 ( cow dung 20 ton/ha) treatment and the lowest was recorded from the control (C0) treatment. In case of boron the maximum plant height at 60 DAT (57.69 cm), spread of plant at 60 DAT (48.44 cm), number of leaves per plant at 60 DAT (11.21), length of the largest leaf at 60 DAT (54.45 cm), primary curd weight (286.78 g), yield per hectare (12.03 t/ha) and the minimum days required for curd initiation (51.17 DAT) were recorded from B2 (boron 2kg/ha) treatment and the lowest was recorded from control (B0) treatment. Regarding combination of cow dung and boron the maximum plant height at 60 DAT (63.11 cm), spread of plant at 60 DAT (52.33 cm), number of leaves per plant at 60 DAT (12.97), length of the largest leaf at 60 DAT (60.25 cm), primary curd weight (399.33 g), yield per hectare (16.71 t/ha) and the minimum days required for curd initiation (50.10 DAT), were recorded from C3B2 (cow dung 20 t/ha and boron 2 kg/ha) treatment and the lowest was recorded from C0B0 (no cow dung and no boron) treatment. The highest production of broccoli is obtained from 20 ton/ha cow dung and 2 kg/ha boron at Horticulture farm condition of Bangladesh Agricultural University, Mymensingh.
