The effect on yield and fruit quality of polyethylene bunch covers applied 1 week after abscission of the last female flower bact was investigated with plant crop bananas in north Queensland. Bunch trimming by removal of the distal 1 or 2 hands of the bunch was investigated in conjunction with bunch covering in one experiment, in a second experiment the same bunch trimming treatments were applied in ratoon crop without bunch covering treatments. Bunch covering increased fruit weight per bunch by 4 percent and decreased the period from bunch emergence to harvest by 5 days. Bunch covering increased finger length of fruit at the proximal end of the bunch only. Yield was reduced by 5 percent by trimming 1 hand per bunch in both experiments and by 15 percent and 13 percent by trimming 2 hands in Experiments 1 and 2 respectively. These yield declines occurred without an accompanying improvement in fruit grades. Thus bunch trimming was unprofitable in north Queensland
