Abstract:
The experiment entitled “Standardization of media and bag size for rebagging Karonda (Carissa carandas) grafts under Konkan Agroclimatic conditions” was carried out at college of Horticulture, Dapoli. Dr. Balasaheb Sawant Konkan Krishi Vidyapith, Dapoli. Dist. Ratnagiri (Maharashtra) during 2020-21 and 2021-22. The objectives of studies were to find out the effect of potting media and to standardize bag size on survival and growth of karonda and laid out in Randomized Block Design. The experiment comprised of eleven treatments and replicated three times and revealed that in karonda from the pooled data of two seasons, the maximum survives (100.00%), highest plant height (49.04 cm), girth above union (6.36 mm), maximum number of leaves (49.88), number of shoots (7.03), number of nodes (6.25) was recorded in T₁₁. The fastest absolute growth rate (0.0650 cm/day), relative growth rate (0.0099 cm/cm/day) was found in T₅. The maximum fresh weight of grafts (76.67 g), longest length of root (38.73 cm), highest number of adventitious roots (27.67), dry weight of root (10.78 g) was recorded in treatment T₁₁ i.e., Bag size 10″×14″ with media Soil + FYM+ Rice husk (1:1:1).
