Abstract
Response of cabbage (Brassica oleracea L. var. capitata), Brussels sprouts (Brassica oleracea var. gemmifera) and broccoli (Brassica oleracea L. var italica) to reduced N rates was studied over 4 yr. Treatments were application methods, broadcast, split and banded with two rates of N; 120 and 90 kg ha −1 plus a control of 150 kg ha −1 broadcast N. Marketable yield was lower by 15, 23, and 13%, respectively, compared to the control. Banding lowered yield of cabbage and broccoli. The lower N rate had the lowest yield in all crops. Leaf N concentration varied with N rate. Key words: Broccoli, Brussels sprouts, cabbage, reduced nitrogen, yield
