Abstract


An experiment was carried out at the research farm of the National Institute for the Promotion of Horticultural Exports, University of Gezira, Wad Medani, Sudan, during the seasons of 2001/02 and 2002/03. The objective was to study the effect of plant spacing and number of suckers on the vegetative growth, yield and fruit quality of the plant crop of selected banana clones. Introduced banana clones Williams Hybrid 172 (WH 172) and Grand Nain 1824 (GN 1824) were compared with the local Dwarf Cavendish (DC) cultivar. Plant spacing was 2x2m, 2x3m and 3x3m and number of suckers were two, three or four per mother plant. Treatments were arranged in a split-split plot design with three replications. Vegetative growth, yield and fruit quality of the plant crop were significantly affected by plant spacing and number of suckers. The wide spacing of 3x3 m (1110 plants/ha) with two suckersĀ  resulted in the most vigorous vegetative growth and best fruit quality as compared with the close spacing of 2x2 m (2500 plants/ha) with four suckers. The clone WH had the best vegetative growth, highest bunch weight, exportable yield and the longest green life followed by GN, whereas, DC resulted in the lowest values of vegetative growth, yield components and green life but recorded the highest total soluble solids content.
