Abstract
Tabernaemontana divaricata (L.) (Crape jasmine) is a commercial important loose flower suitable for year round production in India. Many studies have revealed the beneficial effect of micronutrients viz., ZnSO4, FeSO4, MgSO4, Borax, and Potassium humate on flower crops. Hence, a field experiment was conducted in a farmer’s field at Manarpalyam village of Selam district, Tamilnadu during 2021 to study the effect of foliar application of 7 different combinations of ZnSO4(0.3%), FeSO4(0.5%), MgSO4 (0.3%), Borax(0.3%), and Potassium humate (1%) along with one control treatment. Foliar treatments were applied at 30 days interval. Data pertaining to growth and yield parameters were recorded at periodical intervals. The results revealed that the growth and yield parameters were significantly enhanced in all the treatments when compared to control. The maximum branches, leaves, DMP, number of flowers, flower weight, and flower yield were recorded in treatment with ZnSO4 @ 0.3% + FeSO4 @ 0.5% + MgSO4 @ 0.3 % + Borax 0.3 % + Potassium humate @ 1% on 30 days interval when compared to control. It was followed by the application of ZnSO4 @ 0.3% + FeSO4 @ 0.5% + MgSO4 @ 0.3 % + Potassium humate @ 1% on 30 days interval.
