TI - Response of Oenothera biennis var. grandiflora to different compost levels versus chemical fertilization KW - Evening primrose KW - Fertilizers KW - Organic fertilizers KW - Compost N1 - Includes reference N2 - Oenothera biennis var. grandiflora plants were treated with compost as organic fertilization in comparison with chemical fertilization during the two successive seasons of 2005/2006 and 2006/2007, in the Experimental Nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University. Using compost fertilization considerably increased the total unsaturated fatty acids and linoleic acid was the major unsaturated fatty acid. The highest value 85.59% was obtained with the treatment of 8m³/feddan. Also, the treatments of combination between chemical fertilization and compost produced plants with high total sugar concentration compared to the plants treated with compost only. Data show that all compost levels increased phosphorus concentration in the leaves and roots. It was concluded that compost can improve plant production UR - http://nile.enal.sci.eg/EALE/2008/BFACU/5908/4/281.pdf ER -
