The experiment consisted of 8 treatments which comprising of starter solution, micronutrients mixture and humic acid was laid in Randomized Block Design with three replication. The results of the experiment indicated that application of starter solution @ 0.5% and foliar spray of micronutrients mixture @ 0.25% and humic acid @ 0.2% recorded taller plants with more number of branches per plant and larger leaf area. The same treatment also recorded less number of days for flower initiation and 50% flowering but maximum number of flowers per plant, higher test weight (10 flowers), long duration of flowering, more flower yield per plant and per hectare (13.2t) which was due to improvements in vegetative and flowering characters.
