Abstract : Tommy Atkins mango trees growing in the municipality of Livramento de Nossa Senhora, Bahia, Brazil were sprayed once (on 2 April 1996), twice or 3 times (at 8-day intervals) with 2, 4 or 6% KNO3. Treatment with KNO3 advanced the flowering date by up to 43 days, with no difference between rate or frequency of application, and increased flowering intensity, resulting in a yield increase per plant and per area. KNO3 application had no effect on average fruit weight.
