Foliar spray of boron in November and January was found very effective over soil applications. Among the two foliar treatments, boron spray at 0.2% markedly improved vegetative growth, flower yield and flower quality. The same treatment significantly improved fresh and dry weight of cut flowers, increased water uptake and lengthened the vase life. Treatment with boron, particularly 0.2% foliar spray, was very effective in increasing the uptake of Fe, Zn and B; while no significant difference was noted with N and K uptake.
