Control of recurring flowering in mango by GA₃

Sixty eight varieties of mango were screened for occurrence of recurring flowering. Out of these 28 exhibited problem of recurring flowering whereas rest were free fronl this problem. The variety Alphonso and hybrid (Neelum × Yermalgoa) recorded maximum recurring flowering (20%). For control of recurring flowering in Alphonso mango, an experiment was conducted on 30 years old trees during 1996–1997 and 1998–1999. GA₃ 50, 100, 150, 200 ppm were sprayed at 50% flowering, full bloom and at peanut stage of the Alphonso trees. All the concentrations of GA₃, irrespective of the application time significantly reduced the intensity of recurring flowering in both the year. The GA₃ 50 to 100 ppm sprayed at 50% flowering or at peanut stage is an effective technique for controlling recurring flowering in Alphonso mango.
