An experiment was conducted to study the effect of dehanding and bunch spray of GA₃ and CPPU on the quality of banana cv. Grand Naine at the Banana Research Station, Dr YSR Horticultural University, Pulivendula, A.P, India during 2023-24. Banana tissue culture plants were planted by following a Randomized Block Design with the factorial concept. The experiment included dehanding and growth regulator sprays as factors and 12 different treatment combinations. The maximum total soluble solids, TSS: acid ratio, total sugars, reducing sugars and minimum titratable acidity were observed in T₂ (GA₃ 100 ppm + CPPU 4 ppm) and maximum non-reducing sugars in treatment T₁ (GA₃ 50 ppm + CPPU 4 ppm). Among various levels of dehanding, D₁ (8 hands per bunch after dehanding) showed minimum titratable acidity and maximum TSS: acid ratio. The combination of 8 hands per bunch after dehanding and bunch spray of GA₃ 100 ppm + CPPU 4 ppm (D₁T₂) produced the highest TSS: acid ratio (80.84) and total sugars (21.34%). The highest amount of reducing sugars (14.71%) was found in the treatment combination of 9 hands per bunch after dehanding and bunch spray of GA₃ 100 ppm + CPPU 4 ppm (D₂T₂). The highest non-reducing sugars (8.59%) was observed in dehanding to 9 hands per bunch and spraying with GA₃ 50 ppm + CPPU 4 ppm (D₂T₁).
