This study was carried out at a private farm at El-Makhemala, Abyan Governorate on 2-years old banana plants during 2014-2015 and 2015-2016. Afield experiment was conducted to study the effect of rates of nitrogen on the growth, yield and quality of Musa Cavendishii cv. Dwarf Cavendish. The experiment design was a randomized complete block (RCBD) consisting of six treatments: 0,60,80,100,120,140 g N\plant and four repetition. The results indicated that the high test plant high and circumference of pseudo stem was observed at 120gN\plant, but the highest number of leaves per plant and leaf area was found at 140gN\plant. The maximum number of hands\bunch, number of fingers, bunch weight, fruit yield were reported at 140gN\plant and total soluble solid were recorded at 120gN\plant.
