Effect of foliar application of various nitrogenous chemicals on flowering, fruit set and yield of mango cv. Alphonso was studied at the orchard of Horticultural College and Research Institute, Coimbatore, during 2010 - 2011. Maximum number of flowering shoots (68.7%), number of panicles (7.5/m2), panicle length (31.4cm), number of hermaphrodite flowers (282.5/panicle), fruit set (17.0%), number of fruits (146.0/tree) and fruit yield (43.8 kg/tree) was obtained with foliar spray of KNO3 at 2% concentration. Higher content of chlorophyll (1.7g mg-1), carbohydrate (14.5g 100g-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.

Abstract


Effect of foliar application of various nitrogenous chemicals on flowering, fruit set and yield of mango cv. Alphonso was studied at the orchard of Horticultural College and Research Institute, Coimbatore, during 2010 - 2011. Maximum number of flowering shoots (68.7%), number of panicles (7.5/m2), panicle length (31.4cm), number of hermaphrodite flowers (282.5/panicle), fruit set (17.0%), number of fruits (146.0/tree) and fruit yield (43.8 kg/tree) was obtained with foliar spray of KNO3 at 2% concentration. Higher content of chlorophyll (1.7g mg-1), carbohydrate (14.5g 100g-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.
