Abstract: The present experiment was carried out during September, 2016 to March, 2018 in Research Field of Department of Horticulture, SHUATS, Allahabad. The experiment was conducted in Randomized Block Design (RBD), with thirteen treatments, replicated thrice. The treatments were T_{0 =} Control, T_{1 =} GA₃ 150 ppm, T₂ = GA₃ 200 ppm, T₃ = GA₃ 250 ppm, T₄ = GA₃ 300 ppm, T₅ = NAA 150 ppm, T₆ = NAA 200 ppm, T₇₌ NAA 250 ppm, T_{8 =} NAA 300 ppm, T₉ = CCC 150 ppm, T_{10 =} CCC 200 ppm, T_{11 =} CCC 250 ppm and T_{12 =} CCC 300 ppm. To evaluate shelf life parameters 7 treatments were replicated thrice in randomized design viz. T₁₌ Silver nitrate (100 ppm), T_{2 =} Silver nitrate (200 ppm), T₃ Benzyladenine (100 ppm), T₄ Benzyladenine (200 ppm), T₅ Benzyladenine (100 ppm) + Silver nitrate (100 ppm), T₆ =Benzyaleadenine (200) + Silver nitrate(200ppm), T₇ = Control (water). From the present investigation from two years experimental trial it is concluded that the treatment T₃ (GA₃ 250 ppm) is found to be best in terms of growth and yield parameters as well as cost benefit ratio and lowest was recorded in treatment T₀ (Control) in all the growth and yield parameters, In terms of shelf life of flower the longest shelf life (hours) and lowest physiological loss in weight was recorded in treatment T₄ (Benzyl adenine 200 ppm) followed by treatment T₅ (Benzyl adenine 100 ppm + Silver nitrate 100 ppm) and lowest was recorded in T₇ control (water).
