Abstract:
The experiment entitled “Standardization of media and bag size for rebagging Jackfruit (Artocarpus heterophyllus) grafts under Konkan agroclimatic conditions” was carried out at college of Horticulture, Dapoli. Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, 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 sprouting, survival and growth of propagation of Jackfruit and laid out in Randomized Block Design. The experiment comprised of eleven treatments and replicated three times and revealed that in jackfruit from the pooled data of two seasons, the maximum survive (100.00%) was recorded in treatment T₈ and T₆. The significantly highest height of jackfruit grafts (110.94 cm), girth above union (12.88 mm), maximum number of leaves (41.71), number of shoots (5.32), number of nodes (12.53), fastest absolute growth rate (0.329 cm/day), relative growth rate (0.0215 cm/cm/day), maximum fresh weight of grafts (165.67 g), highest number of adventitious roots (101.88), dry weight of root (35.06 g) was recorded in treatment T₈ i.e. Bag size 10″×14″ with media Soil + Vermicompost (2:1). Whereas, the longest length of root (45.97 cm) was recorded in T₁₁ i.e. Bag size 10″×14″ with media Soil + FYM+ Rice husk (1:1:1).
