Flush Intensity of Mango (Mangifera indica L. c.v. Carabao mango) Leaves as Affected by Different Flush Induction Protocol

Abstract

The study was carried out to validate the effect of different flush induction protocol on carabao mango which was conducted in Alion, Mariveles, Bataan, Philippines with the following treatments: no intervention (T1), pruning only (T2), pruning with urea applied in soil (T3), pruning with urea spray (T4), pruning with irrigation (T5), and complete flush induction protocol (T6). Results revealed that providing water hasten the flush induction of mango. The complete flush induction protocol (T6) significantly had the highest flushing percentage and the longest flushing duration. In terms of leaf produced per flush, pruning alone (T2) and pruning with urea spray (T4) equally produced the highest number of leaves per flush having 16 leaves. On the other hand, different flush induction protocols have no direct effect on flush and stem length, stem diameter, flush dry weight, and in the amount of nutrients in the flushes except for total amount of iron.
