Ratna. M.Sc. Thesis, Dr BSKKV, DapoliDr BSKKV, Dapolihttps://krishikosh.egranth.ac.in/handle/1/5810191887The present investigation entitled “Studies on effect of special horticultural practices on induction of flowering in mango (Mangifera indica L.) cv. Ratna” was carried out at College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli (M.S.) during season of 2020-21. The experiment was laid out in Randomized Block Design with ten treatments namely, T1 (girdling on first fortnight of October), T2 (girdling on first fortnight of November), T3 (girdling on first fortnight of October and November), T4 (girdling on first fortnight of October and tip pruning), T5 (girdling on first fortnight of November and tip pruning), T6 (girdling on first fortnight October and November and tip pruning), T7 (tip pruning), T8 (removal of new shoots below old shoot), T9 (smudging) and T10 (control) which were replicated three times. The morphological parameters viz., days required from treatment exposure to panicle emergence, flowering intensity, length and width of panicle, no. of rachis per panicle, hermaphrodite flowers (%), fruit set, fruit retention (%), yield and days required from flowering to harvesting were significantly varied due to girdling,tip pruning and smudging. The chemical parameters of the fruits were not influenced significantly by girdling, tip pruning and smudging. Treatment T5 (girdling on first fortnight of November and tip pruning) showed best performance for flowering intensity (62.27 %), hermaphrodite flowers (15.01 %), fruit set (8.53 %), fruit retention (0.95 %) and the yield (144.00 no. of fruits/tree, 61.58 kg/tree). T7 (tip pruning) resulted in early panicle emergence (40.83 days) which led to early harvest (134.87 days). The physical parameters viz. fruit weight, fruit length, fruit diameter, pulp weight and pulp to stone ratio were affected significantly due to girdling, tip pruning and smudging. From present investigation, it was concluded that girdling and tip pruning in mango cv. Ratna helped for early panicle emergence and further led to early harvest with high yield.EnglishThesis
