Abstract: The aim this work was evaluate the effects of water and nitrogen (N) levels, supplied by drip system, on yield and water use efficiency of onion crop (Allium cepa L.). The experiment was carried at the experimental area of DEG/UFLA, in a randomized block statistical design was used, in a factorial scheme 4 x 4, with three replicates. Four irrigation depths based on Class A evaporation tanks (50, 100, 150 and 200%) and four N doses (0, 60, 120 and 180 kg ha-1) were supplied through irrigation water (fertigation). It can be concluded that higher yields (total bulbs and of marketable bulbs) and higher average marketable bulbs mass were obtained with the irrigation depth of 512.7 mm (100% Class A) and 180 kg ha-1 of N. Water use efficiency decreased linearly as irrigation depths increased and N rate decreased.
