Abstract

To observe the growth and yield attributes of cabbage under different spacing and nitrogen fertilizers, a field experiment was conducted with cabbage (Brassica oleracea var. capitata L.) variety “BARI Badha kopi-2 (Agradut)”. The experiment was carried out at the research field of the Department of Crop Science and Technology, Rajshahi University, Rajshahi during the period from November, 2021 to March, 2022. The experiment consisted of three spacing i.e. 50cmX30cm, 50cmX40cm and 50cmX50cm 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 (50cmX50cm) combination with highest level of nitrogen fertilizer (150kg/ha) produced the maximum plant height, no. of leaves per plant, largest leaf length, largest leaf breadth, head diameter, head thickness, individual head weight and yield whereas50cmX30cm spacing and lowest level of nitrogen fertilizer (50kg/ha)required maximum days required for head maturity. On the other hand, all the studied parameters except days required for head maturity found to be lowest in the treatment combination of 50cmX30cm spacing with lower level of nitrogen fertilizer (50kg/ha).The study concluded that cabbage need to be cultivated at 50cmX50cmspacing and 150kg/ha nitrogen fertilizer is to be applied for getting the targeted yield as well as desired return from cabbage cultivation in “High Ganges River Floodplain zones” of Bangladesh.
