Abstact: A 2-year experiment was conducted to find out the effect of nitrogen and phosphorus on growth and seed yield of dill (Anethum sowa Roxb). The crop planted during rabi 2006-07 and 2007-08. The nitrogen application upto 90 kg ha-1 significantly increased the number of umbels per plant, seeds per umbel, seed yield, straw yield and biological yield, net returns and B:C ratio. Whereas, branches per plant increased significantly upto 60 kg N ha-1 . Significantly higher seed yield (1239 kg ha-1) , net returns (Rs.27890 ha1) and B:C ratio (3.24)was recorded with 90 kg N while, significant increase in yield attributes like number of umbels per plant, seeds per umbel , seed yield, straw yield, biological yield, net returns and B:C ratio of dill was observed upto 40 kg P2O5 ha-1. Whereas, branches per plant, test weight, harvest index, significantly increased upto 20 kg P2O5 ha-1 . Significantly higher seed yield (1163 kg ha-1 ), net returns (Rs. 25507 ha-1)and B:C ratio (3.05) were recorded with 40 kg P2O5 ha-1. Interaction effect of 90kg N with 40kg P2O5 ha-1 were found significant higher for umbels per plant and seed yield.
