Nutrient management for cabbage

IPNI-2014-CHN-CQ19

The objectives of the 2014 project were to determine the optimal N and K rates for fall Chinese cabbage in comparison with the summer variety tested in 2013. The experiment consisted of six treatments including two N rates (300 and 375 kg N/ha), one P rate (90 kg/ha) and four K rates (0, 75, 150, and 225 kg K2O/ha). Nitrogen and K fertilizers were split three times between a basal application at seeding (30%), and topdressing at seedling (30%) and rosette stages (40%). Read more
