An experiment was conducted for the development of specific foliar formulation to increase the flower characters and yield in Jasminum sambac in the field level for two years 2018-2020. Two or three micro nutrients deficiencies occurring simultaneously in the flower crop is difficult to be corrected by spraying a single nutrient or multiple sprays. The investigation was conducted with Ramanathapuram Gundu variety with six treatments with three replications and in RBD model. The foliar formulations sprays were carried out for three times during January, February and March 2018 to 2020 and measurement of growth, flowering characters, estimation of gas exchange traits and physiological parameters were estimated.Among the treatments the foliar application of MgSO4 (0.3%) + FeSO4 (0.5%) + K2SO4 (0.5%) + Borax (0.3%) (T4) recorded the highest flower diameter, bud length and the physiological parameters like NRase activity and soluble protein and the SPAD value were found to the highest in the above foliar formulation with an estimated yield of 7.55 t ha-1 and the yield increment of 42% over the control (5.30 t ha-1) with a BC ratio of 3.05.
