Standardization of Rooting Media and PGR Levels for Successful Softwood Cutting Propagation in Guava (L-49)

The present investigation, titled “Studies on propagation guava through cutting” was conducted under shadenet condition during September 2021 to January 2022 at Research cum Demonstration Farm, college of Agriculture, Dhule, Maharashtra. The experiment was set in a Factorial randomized block design (FRBD) which comprised of two factors viz. different rooting media (7 treatments) and growth regulators (5 treatments) making 35 treatment combination and were replicated three times. The results revealed that the interaction between rooting media and growth regulators were complementary the interaction treatment T17 (Soil+ Perlite + IBA-4000 ppm) was found to be ideal as it recorded promising performance for the characters studied except the characters days required to rooting and length of root. It recorded maximum values for success percentage (83.13 %), 23.34 leaves per cutting at 120 DAP, number of shoots at 120 DAP (3.87), number of primary roots per cutting (4.30), number of secondary roots (8.34), highest fresh weight of roots (4.3 g), highest dry weight of roots (0.97 g) and highest survival percentage (54.63 %). The results revealed importance of IBA at 4000 ppm concentration along with root media Soil+ Perlite (1:1) for better leaf, shoot and root characters and also survival of the soft wood cuttings in guava.
