Physiological performance and economics of foxtail millet [Setaria italica (L.)] varieties to different nitrogen levels

Abstract

The experiment was conducted with four foxtail millet varieties (Prasad, Narasimharaya, SiA 3156 and CO-2) and four nitrogen levels (0, 20, 40 and 60 kg N ha-1) on sandy clay soil of Agricultural College Farm, Bapatla, during kharif, 2018. Results of the experimentrevealed that the variety Prasad and 60 kg N ha-1 application recorded the highest SPAD chlorophyll, crop growth rate and relative growth rate at grain development stage and also recorded the highest leaf area index, grain, stover yields, gross returns, net returns and returns per rupee investment.
