A field experiment was conducted at IGAU, Raipur during 2001-02 and 2002-03 in hybrid rice-safflower cropping system. Maximum seed yield and all energy parameters were highest under the residual effect of 75% rec. N blended with CDU. As regards to direct effect, 100 % rec. N produced maximum seed yield. Whereas, energy parameters . energy use efficiency, energy productivity and energy output input ratio were highest under no nitrogen. | Influence of integrated nitrogen nourishment on seed yield and energetics of safflower in hybrid rice- safflower cropping system
