Modified Off–Season Technology to the Flowering Time and Fruit Yield of Arumanis Mango (Mangifera indica L.)

The purpose of this study was to observe the technology of
mango fruit production at off-season used growth regulators. The research
was conducted with three treatments namely: i) Paclobutrazol dosage
(control, 5 mL L–1 per tree, 10 mL L–1 per tree and 15 L–1 per tree).
ii) Ethephon dosages (0 mL L-1 per tree, 400 mL L–1 per tree, 600 mL L–1
per tree and 800 mL L–1 per tree) that applied 1 mo after paclobutrazol
addition. iii) Paclobutrazol (P) and organic fertilizer (F) application in
combination as follows: (control, 5 mL + 10 kg, 10 mL + 15 kg, 15 mL +
20 kg) Randomized Completely Block Designed (RCBD) with five
replications was used. The results indicated that i) Paclobutrazol
application accelerated the flowering age, shortens the panicle length, and
increased fruit yield of the tree. ii) Giving Ethephon accelerated the
flowering period, enhanced both the panicles number and yields. The
treatment of ethephones 600 mL L–1 produced the highest fruit weight,
182.60 kg, respectively iii) The Paclobutrazol and organic fertilizer
application indicated significantly (p < 0.05) to the panicles number and
the fruit weight yield is higher than the control.
