PROMOTING THE GROWTH AND YIELD OF CAULIFLOWER VARIETIES THROUGH THE APPLICATION OF MOLYBDENUM

Abstract

An experiment was conducted during the rabi season (November 2021 to February 2022) at Horticulture Farm of Sher-e-Bangla Agricultural University (SAU), Dhaka-1207, Bangladesh to study the effect of molybdenum on the growth, yield and bio-chemical properties of purple cauliflower. The local variety BARI Fulkopi1(Rupa) was used as a check variety and exotic purple cauliflower cultivar was used as test variety in the experiment. The experiment consisted of the following treatments, such as T 1 : Rupa + 0 Kg/ha Molybdenum, T 2 : Rupa + 0.5 Kg/ha Molybdenum, T 3 : Rupa + 1.0 Kg/ha Molybdenum, T 4 : Rupa + 1.5 Kg/ha Molybdenum, T 5 : Exotic Purple + 0 Kg/ha Molybdenum, T 6 : Exotic Purple + 0.5 Kg/ha Molybdenum, T 7 : Exotic Purple + 1.0 Kg/ha Molybdenum and T 8 : Exotic Purple + 1.5 Kg/ha Molybdenum. The treatments of the experiment were laid out in Randomized Complete Block Design (RCBD) with three replications. Different level of molybdenum showed significant variation on plant height at 20, 40 and 60 DAT. The highest weight of curd (660.15 g) was found in treatment T 8 whereas, the lowest weight of curd (406.81 g) was found in treatment T 1 . Similarly, the biochemical properties were found better in treatment T 8 than other treatments. It can be concluded that, the growers can use 1.5 Kg/ha Molybdenum for successful production of purple cauliflower.
