Zinc and boron are the most important trace nutrients for crop production. In recent years, cultivable lands in Bangladesh suffer deficiency of these elements. This research aimed to find out a suitable and effective application method to improve the overall soil nutrient up-gradation for crop production. Here, the treatments were control (T0), soil application of zinc (T1), soil application of boron (T2), foliar application of zinc (T3), foliar application of boron (T4), soil application of zinc and boron (T5), soil application of zinc with foliar application of boron (T6), soil application of boron with foliar application of zinc (T7), and foliar application of zinc and boron (T8). The source of zinc @ 3 kg ha-1 and boron @ 2 kg ha-1 as a basal dose were zinc sulphate and borax, respectively. The foliar application of zinc and boron was done at 45 and 60 days after transplanting @ 1% and the source were chelated zinc and solubor boron, respectively. The result of the experiment was concerning the highest plant height, plant spreading, the number of leaves, stem length, stem diameter, fresh weight of loose leaves, head diameter, head thickness, dry matter content of head, and yield. The highest yield of cabbage was found with the treatment foliar application of zinc and boron (T8). The results of this investigation revealed that the application methods of zinc and boron positively affect the growth and yield of cabbage whereas foliar application of these nutrients always makes higher growth parameters with yield.
