Effect of foliar application of various nitrogenous chemicals on flowering, fruit set and yield of mango cv. Alphonsowas studied at the orchard of Horticultural College and Research Institute, Coimbatore, during 2010 - 2011. Maximumnumber of flowering shoots (68.7%), number of panicles (7.5/m2), panicle length (31.4cm), number of hermaphroditeflowers (282.5/panicle), fruit set (17.0%), number of fruits (146.0/tree) and fruit yield (43.8 kg/tree) was obtainedwith foliar spray of KNO3 at 2% concentration. Higher content of chlorophyll (1.7g mg-1), carbohydrate (14.5g100g-1) and nitrogen (1.43%) and higher C/N ratio (10.18) were also recorded in plants sprayed with 2% KNO3,followed by 1% KNO3.
