Abstract: An experiment was conducted to study the effect of different concentration of Ethrel in comparison with the commercial form of growth promoter ace in promoting growth and yield of black cumin during 2006 and 2007. The experiment was laid out in a Randomized Block Design having 6 treatments replicated thrice. In this experiment growth regulators were Ethrel (50 ppm, 75 ppm, 100 ppm and 125 ppm) along with ace (a commercial bioregulator @ 0.5 ml/lit). Further to get a comparison one untreated control treatment was included to have a clear picture of controlled plants as compared to growth regulator treatment. The results clearly indicated that there was increase in seed yield with all the treatments except the control (untreated) plot. Among all the treatments, Ethrel @ 75 ppm proved to be most effective in promoting growth and gave highest seed yield (6.03 q/ha), followed by Ethrel @ 100 ppm (5.59 q/ha) which was statistically at par.
