A field experiment was conducted at Udaipur (Rajasthan) to study the effect of three plantdensities, four fertilizer treatments and two growth regulators on yield maximization oftransplanted fennel (Foeniculum vulgare). Planting of fennel at a density of 27,770 plants ha-1recorded significantly higher yield attributes (umbels plant-1, seed yield plant-1 and test weight),while seed yield ha-1 was higher with a density of 55,550 plants ha-1 (20.89 q ha-1). Applicationof 90 kg N + 40 kg P2O5 + 20 kg K2O + 20 kg S + 5 kg Zn ha-1 recorded significantly higher yieldattributes and yield of fennel during both the years. Application of naphthalene acetic acid100 ppm recorded significantly higher yield attributes and seed yield.
