A field experiment entitled “RESPONSE OF DIFFERENT MONTH OF RATOONING WITH BUNCH SPRAY OF GA3 AND BA ON QUALITY OF BANANA (Musa paradisiaca L.) cv. GRAND NAIN” was carried out at the Instructional Farm and Regional Horticultural Research Station of the Navsari Agricultural University, Navsari, Gujarat, India during 2018-19 and 2019-20. The results revealed that M2 treatment (7 month after planting) gave maximum fruit firmness, fruit volume and minimum physiological loss of weight. While, M3 treatment (8 months after planting) gave maximum ascorbic acid, non-reducing sugar, total sugar and sugar: acidity ratio.

Foliar application of GA3 100 mgl-1 + BA 25 mgl-1(S3) after complete opening of the significantly gave the maximum fruit firmness, TSS, ascorbic acid, pulp weight, peel weight, sugar: acidity ratio and shelf life of banana fruits and minimum physiological loss of weight and acidity.

When banana cv. Grand Nain ratoon kept at 6 month after planting and foliar spray of GA3 100 mgl-1 + BA 25 mgl-1 after complete opening of banana bunch (M1S3) gave significantly maximum fruit firmness and shelf life of fruits. However, M2S3 (7 month after planting and GA3 100 mgl-1 + BA 25 mgl-1) significantly gave the minimum physiological loss of weight.
