A pot trial was carried out to study the effect of foliar spray of 0 (de-ionized water), 10−6, 10−5 and −4 M each of gibberellic acid (GA3) or Kinetin (KIN) at 40 days after sowing (vegetative stage) on growth and yield of black cumin (Nigella sativa L.). GA3 application at 10−5 M concentration was found to be more effective than KIN in promoting shoot length, plant dry weight, leaf number, leaf area and branch number observed 70 days after sowing (DAS). Application of 10−5 M GA3 resulted in more capsule number, seed yield and seed yield merit, which was found increased by 43.33, 43.85 and 53.62% respectively.
