Abstract:

A field experiment was conducted to find out the effect of different growth retardants on yield and yield contributing characters in mango (Mangifera indica L.) cv. Alphonso under Ultra High Density Planting during 2013-2014 at Jain Irrigation Systems Limited (JISL) Farms, in Tamil Nadu. Eleven treatments with different combinations were imposed on five-year-old uniform sized Alphonso trees grown under a spacing of 3 x 2 m. The highest number of panicles per m2canopy area and number of panicles per tree were recorded in the paclobutrazol treatments with application of ethephon or alone and in uniconazole (1.5 g/l) foliar spray. The treatments paclobutrazol + KNO3, uniconazole @ 1.5 g/l and ethephon @ 500 ppm recorded the highest flowering intensity. However, paclobutrazol combined with ethephon or KNO3 and uniconazole alone recorded the advancement of flowering. The percentage of hermaphrodite flowers was higher in treatments where paclobutrazol combined with 1000 ppm of ethephon and KNO3 spray. However, the paclobutrazol alone or with KNO3 and uniconazole alone recorded the highest percentage of fruit set in the trees. Higher concentration of uniconazole recorded the highest number of fruits and yield.


Keywords: Uniconazole, Paclobutrazol, Ethephon, Mango flowering, Fruit set and yield.
