Cabbage, fertilizer, growth, profitability, quality, yieldAbstract
A two years field experiment was conducted during the rabi seasons of 2019-20 and 2020-21 in factorial randomized design with three replications, consisting five levels of nitrogen (kg/ha) (75, 100, 125, 150 and 175) and four levels of potassium (kg/ha) (50, 75, 100 and 125) encompassing twenty treatments combination. The pooled analysis revealed that different doses nitrogen and potassium significantly influenced vegetative growth, yield and quality of cabbage. The combined application of nitrogen (175 kg/ha) + potassium (125 kg/ha) recorded the maximum plant height, stem diameter, head width, head weight, yield per plots and yield per hectare. From the economic analysis, the combined application of nitrogen (175 kg/ha) + potassium (125 kg/ha), and nitrogen (175 kg/ha) and potassium (100 kg/ha) recorded highest B:C ratio (1.95). From the above findings, it can be suggest that the combination of nitrogen (175 kg/ha) + potassium (125 kg/ha) will be profitable to the cabbage growers of West Bengal, India.
