Abstract: The present study was conducted in two successive seasons (2009/2010 and 2010/2011) on the first and second ratoons of Williams banana plants cultivated in loamy clay soil under flood irrigation at a private orchard located at Tanta, Gharbia Governorate, Egypt. Four planting densities (ranged from 933 to 1400 plants feddan-1) were examined to study their effect on vegetative growth, flowering, yield and fruit quality of Williams banana. Banana plants grown at close spacing had taller pseudostem than plants grown under wide spacing. The highest yield per feddan was obtained from plants spaced at 3x2 m with two plants per hole, followed by those at 3x1 m, with one plant per hole since it was 34.07 and 30.33 tons in the first ratoon and 34.80 and 31.50 in the second ratoon for both planting distances, respectively. Earliest bunch shooting and minimum days for harvesting were recorded with planting distance 3x4 m with three plants per hole and bunch emerged earlier (12-13 days) than bunches produced from plants spaced at 3x1 m with one plants per hole in both first and second ratoons, respectively. Heaviest bunches were harvested from plants at 3x4 m spacing with three plants per hole. Increasing yield per feddan by this planting distance could be attributed mainly to the increasing number of plants in the area unit. The highest finger weight, length, Total Soluble Solids (TSS%) and total sugars% were produced from plant spaced at 3x4 m with three plants per hole.
