A field experiment was conducted for 5 years (1 996-97 to 2000-2001) at Regional Agricultural Research Station, Nandyal, revealed that among different cropping sequences involving sunflower (Helianthus annuus L.) the sunflower-equivalent yield of groundnut (Arachis hypogaea L.)-sunflower was the highest (1,555 kglha) and was at par with setaria (Setaria sp.)-sunflower (1,545 kglha) and sunflower-sunflower (1,503 kglha). The net re- turns and benefit : cost ratio were the highest for setaria-sunflower followed by sunflower-sunflower sequence. The soil fertility status of rainfed cropping systems involving pulse crops was better than that involving non-pulse crops in the sequence.References
