Abstract

The present study aimed to evaluated the effect of irrigation using water containing CPX residues on alfalfa ( Medicago sativa) carbon fixation, number of root nodules and root length. A surface layer soil from Piracicaba, SP, Brazil (22°42’49’’ S, 47°37’12” O) in pristine purity conditions was used, adjusting soil pH to neutrality levels, and alfalfa ( Medicago sativa ) seeds inoculated with Rizhobium sp. were distributed in 12 pots comprising three treatments employing three repetitions with three controls. The experiment was conducted in a plant growth chamber, where six irrigations were carried out with type-2 water contaminated with ciprofloxacin at 1, 10 and 100 µg L -1 for 40 days. The presence of CFX in irrigation water decreased carbon fixation in alfalfa stems and leaves by up to 8.9%, also reducing the number of root nodules by 95%, and leading to their elongation.
