This investigation was conducted during two successive seasons 2015 and 2016 on (Musa sp.) cv. Grand Nain plants grown in in private orchard  in Badr center, Behira governorate, Egypt, to study theeffect of bunch covers and bunch trimming on growth, yield and fruit quality of banana.  A split plot designed experiment was carried out where the four bunch covers (untreated, white, blue and double bags) were arranged in main plots, four bunch trimming (untreated, removing one, two and three hands) were arranged in sub plots. Results revealed that the treatment of double bags and removing  three hands gave the highest mean values of yield and fruit quality as (finger length, diameter and weight, earliness of harvesting time (days), yield, pulp weight, pulp (%),number of finger/ hand, bunch and hand weights compared with control and other treatments during both seasons. Also, results indicated that, the treatment of bunch trimming (removing three hands) gave the maximum mean values of (finger length, diameter and weight, earlier time of harvesting (days), yield, pulp weight, pulp (%),number of fingers/ hand, bunch and hand weights) compared with control and other treatments during both seasons.
