Growth, yield and quality attributes of tissue cultured banana as affected by bio-fertilizers

An experiment was carried out in the Department of Horticulture, C.S. Azad University of Agriculture and Technology, Kanpur (U.P.), India during 2010–11 on tissue cultured banana cv. Grand Naine with ten treatments including a control, replicated thrice in randomized block design. It was recorded that the height and girth of pseudostem (146.16 and 65.33 cm, respectively), total number of leaves (34.33), total number of functional leaves per plant at the time of emergence of inflorescence (17.33) and length of inflorescence (112.83 cm) were maximum in the plants treated with 50 g Azotobacter + 50 g Azospirillum + 50 g PSB + 50 g Trichoderma harzianum per plant as compared to non treated ones. Same treatment also resulted maximum bunch weight (22.25 kg), number of fingers per hand and per bunch (16.66 and 143.00, respectively), number of hands per bunch (8.33), finger weight (135.83 g), length (19.16 cm), diameter (15.33 cm), TSS (19.00°Brix), total sugars (18.68%), pulp (80.86%) and pulp:peel ratio (4.22) with reduced peel (19.14%) and titratable acidity (0.47%).
