Abstract

An experiment was conducted on primary hardening in tissue culture banana cv. Karpura Chakkerakeli (AAB) plantlets at Dr. YSRHU-HRS, Kovvur, in the year 2022-23. Banana cv. Karpura Chakkerakeli (AAB) is choicest table variety in Godavari districts of Andhra Pradesh. Poor in vitro root induction and ex vitro survival are the major hindrance for its large scale commercial production. Therefore, the objective of the present investigation was to develop an efficient growth media and different containers for in vitro rooting and ex vitro performance. This experiment was conducted to find out suitable potting mixture and containers on hardening in shade net. In which different potting mixtures of M1-red earth (2) + FYM (1) + coco peat (1), M2- red earth (2) + FYM (1) + rice husk (1), M3- red earth (2) + FYM (1) + sand (1), M4-vermicompost (1) + coco peat (1), M5-vermicompost (1) + rice husk (1), M6 –Vermicompost (1) + sand (1) and two different containers C1- poly bags and C2- disposable plastic glass tested, the maximum Per cent rooting (92.63%), Number of primary root (9.50), Number of secondary roots (26.50) and Length of longest root (13.21) was recorded in M1 × C1 treatment interaction and shows outstanding performances in field condition.

Keywords

Red earth, Vermicompost, sand, husk, Containers, Karpura Chakkerakeli (AAB)

Conclusion

Red earth and coco peat and FYM in poly bags was the best combination on maximum survival and also good rooting characters viz. percentage of rooting and primary and secondary rooting during hardening period in banana cv. Karpura Chakkarakeli (AAB).
