Foliar application of either GA3 (20mgL-1), or a nutrient solution (comprising of KNO3, 19mgL-1; NH4NO3, 16.5 mgL-1; KH2PO4, 1.7mgL-1, CaCl2, 4.4 mgL-1 and MgSO4, 3.7mgL-1) or both on lily plants was undertaken. It was found that flower stem length of the plants sprayed with nutrients alone increased by 25% over those of the control plants. Mean shoot length of the plants sprayed with both the hormones and nutrients increased by 33% over the control plants and by 6% over the other set of plants, which received the treatment of nutrients alone. Number of nodes per stem was also found to increase in the dually treated plants by 71% and 42% in that order. The plants receiving dual treatment harbored 92% greater number of buds per stem over the control plants whereas nutrients alone treated lily plant showed only 28% greater number of buds. Mean number of flowers produced by nutrient fed plants was 14% greater over the control plants. Foliar application of GA3 and nutrients appl
