A field experiment was conducted at the research field of the Department of Crop Science and Technology, University of Rajshahi, Rajshahi to evaluate the effect of spacing and nitrogenous fertilizer on the growth and yield attributes of cabbage. In the study, the cabbage (Brassica oleracea var. capitata L.) variety “BARI Badha kopi-2 (Agradut)” was cultivated during Rabi season (November 2023 to January 2024). The experiment consisted of three spacing i.e. 50cm×30cm, 50cm×40cm and 50cm×50cm as well as three levels of nitrogen fertilizers viz. 50kg/ha, 100kg/ha and 150kg/ha. The results revealed that different treatments significantly affected the growth and yield attributes of cabbage. The combination of wider spacing (50cm×50cm) with highest level of nitrogenous fertilizer (150kg/ha) produced the maximum plant height (40.57 cm), head diameter (23.83 cm), head thickness (15.89 cm), fresh head weight head (1.59 kg), yield per plot (39.92 kg) and yield (63.87 t/ha), whereas closer spacing (50cm×30cm) and lowest level of nitrogenous fertilizer (50kg/ha) required maximum days required to head formation (47.10) and head maturity (98.00). The study concluded that 50cm×50cm spacing and 150kg/ha nitrogenous fertilizer is to be needed for getting maximum yield from cabbage cultivation.
Key words: Spacing, nitrogenous fertilizer, growth and yield, cabbage.
