Abstract
The effect of three nitrogen N concentrations 3.57 7.14 or 14 28 mM on cauliflower Brassica oleracea var. botrytis growth and yield were evaluated on coconut coir dust CD and palm oil empty fruit bunch EFB grown in the greenhouse. There was no significant media CO EFB X N concentration interactions for either plant growth parameters and total N concentration in the leaves at 21 days after planting DAP. The growth of cauliflower was higher in CD than that in EFB. Plants grown in EFB were severely damaged due to fungal and mushroom growth in the media. Increasing N increased the total leaf area leaf and stem dry matter of plants grown in CD. Curd diameter and dry weight were highest at highest N. Total N concentration in the leaf and stem increased with increasing N. However total N concentration in both leaf and stem was decreased at the later growth stage for all treatments indicating a mobilization of N in the plant. Although nitrate concentration in the curd was lowest at lowest N and highest at high N the concentration was under permissible levels in Europe with reference to broccoli Brassica oleracea L. italica.
