Abstract


Banana cultivation in Sudan is restricted to the narrow strip of silt deposits along the banks of the Blue Nile and the River Nile. Hence, there is a need to expand banana cultivation in the high terrace, heavy clay soils. Banana performance in heavy clay soils is very poor, unless soil amendments are applied. Therefore, the objective of this research was to study the effects of soil amendment treatments on growth, yield and fruit quality of selected banana cultivars. The experiment was conducted in the Research Farm of the National Institute for the Promotion of Horticultural Exports, University of Gezira, during 2009-2011. Treatments consisted of three selected banana cultivars : Two introduced cultivars, namely, Grand Nain 1824 (GN) and William’s Hybrid 172 (WH) and the local cultivar Dwarf Cavendish (DC). Soil amendment treatments were : 1, 50% heavy clay (HC) + 50% loam (L); 2, 50% HC + 50% chicken manure (CM); 3, 50% HC + 25% L + 25% CM; 4, 33% HC + 33% L + 34% CM; 5, 100% HC (control). Treatments were arranged in a randomized complete block design with three replicates. Results showed that the introduced cultivars GN and WH had more vigorous vegetative growth, higher yield components, total yield and better fruit quality than the local cultivar DC. Soil amendment treatments of 50% HC + 25% L + 25% CM and 33% HC + 33% L + 34% CM resulted in the most vigorous vegetative growth, the highest yield components and total yield and the best fruit quality, followed by 50% HC + 50% L and 50% HC +50%CM, whereas the least vegetative growth, the lowest yield components, total yield and the worst fruit quality were produced by bananas grown in 100% HC (control). In order to expand banana production for the local market and export, it is recommended to amend heavy clay soils with loams and chicken manure at 33% each and grow the introduced cultivars GN and WH.
