Effect of foliar application of various nitrogenous, phosphorus and ethylene chemicals on flowering, fruit set and yield of mango variety Bangalora was studied at the Santhur, Pochampalli, Krishnagiri District during 2012 - 2017. Seven foliar treatments comprised of T1 as control T2 and T3 - KNO3@ 2% spray with and without 1% Urea respectively.T4-KH2PO4 @1% T5-NH4NO3 @ 2%, T6 and T7 -Ethephon @ 400ppm and 800 ppm concentration respectively with three successive foliar sprays replicated thrice in twenty five year old ‘Bangalora’ mango orchard. Paclobutrazol (PBZ) is applied for all the trees @ 5ml/tree during the month of April. The experiment was laid out in Randomized Block Design with three replications, and a single tree was treated as a unit/treatment. The soil application of paclobutrazol @ 5ml/tree during April month and three successive foliar sprays of KH2PO4 @ 1% at an interval of 30 days during May, June and July months resulted in the highest number of fruits per tree (391.87), individual fruit weight (452g), the maximum yield per tree (198.45 kg/tree) during the off season followed by the spray of KNO3 @ 2% with an yield of 186.22 kg/tree.
