Abstract
Nitrogen fertilization is useful and widespread to obtain higher growth and quality of productions. To evaluate the influence of nitrogen-rich fertilizers on the quality characteristics, shelf-life tests of celery grown with two levels (80-120 kg ha-1) of two different nitrogen fertilizers were performed. Celery plants were selected and packed in two plastic films (anti-fog polyolefin and micro-perforated polypropylene). Nitrate contents, weight loss, hardness, changes in colour parameters and total phenols, were studied in both packaging solutions during storage. Results showed that celery fertilized with organic nitrogen and packed in anti-fog polyolefin reached a shelf-life of 37 days. Not treated sample packed in micro-perforated polypropylene was not marketable after 20 days, while the same sample packed in anti-fog polyolefin reached 30 days.
