Abstract: Field studies were conducted in West Bengal, India, in 2008-09 and 2009-10, to determine the effect of gibberellic acid (GA3) and NAA on the growth and yield of black cumin. The treatments comprised 25 (T1), 50 (T2), 75 (T3), 100 ppm GA3 (T4), 25 (T5), 50 (T6), 75 (T7), 100 ppm NAA (T8) and control (T9). Data were recorded on the plant height, branches per plant, pods per plant, fruit length, fruit diameter, 1000 seed weight, seed yield and volatile oil content of black cumin. Results showed that GA3 had a significant function on cell division in the apical meristem, whereas, NAA at higher concentrations induced the reproductive phase. Hence, the vegetative parameters showed better results with increased concentration of GA3, however, seed yield and other yield attributes showed significant increase with the application of NAA at higher concentrations. NAA at 100 ppm was the best treatment and recorded the maximum seed yield of black cumin.
