A field experiment was conducted to study fertilizer management in clusterbean in alfisols of Scarce Rainfall Zone under rainfed conditions for three years during kharif, 2013-14, 2014-15 and 2015-16 at Agricultural Research Station, Ananthapuramu, Andhra Pradesh. Pooled analysis of data revealed that number of pods per plant, seed yield, gross returns, net returns and B:C ratio was not significantly influenced by different fertilizer management practices. However, the highest mean number of pods per plant was resulted with application of 20 kg K ha-1, seed yield was registered with 20 kg N + 20 kg P + 20 kg K+ 3 kg Bo ha-1. Higher gross returns were realized with 20 kg N + 20 kg P + 20 kg K+ 3 kg Bo ha-1, highest net returns obtained with 20 kg N ha-1 and highest benefit cost ratio was realized with 20 kg N ha-1. Application of 20 kg N ha-1 can be recommended to Scarce Rainfall Zone of Andhra Pradesh of for maximization of profits in clusterbean crop.
