| The effect of different agronomic strategies on the nutritional quality of head lettuce was investigated. The factors included were irrigation type, fertiliser input type and level. The assessed ingredient parameters were nitrate, lutein, ß-carotene and polyphenols. Hygiene was described by total aerobic bacterial count and number of coliform bacteria, Escherichia coli, Salmonella enteritidis, Enterococcus and Enterobacteriaceae. Lettuce treated with mineral nitrogen fertiliser (calcium ammonium nitrate) displayed a higher nitrate content than lettuce treated with organic manures (fresh farmyard manure (FYM), rotten FYM (fermented nettle extract). Nitrate concentration in lettuce tended to increase with increasing amounts of fertiliser, independent of... |
