Effects of GA and boron on growth, flowering and yield of Siratro (Macraptilium atropurpureum) plants was studied in pot culture condition. Plant height was maximum in 50 ppm GA treatment followed by 1 ppm boron over control. Early flowering upto 5 days was noticed in treated plants. Total number of flowers was also increased in 50 ppm GA followed by 1 ppm boron. Seed yield and 1000 seed weight increased significantly, maximum being in 1 ppm boron followed by 50 ppm GA.
