A field experiment framed in split plot design was conducted to check response of cluster bean to irrigation and nitrogen levels under micro sprinklerat research farm of All India Co-ordinate Research Project for Dryland Agriculture, Dr. PDKV, Akola during 29 January to 28 May 2015. The experiment comprised of three main treatments of irrigation (I1,I2, I3) and three sub treatments of nitrogen (T1, T2, T3) with four replication. Seasonal water requirement of cluster bean was found to be highest under irrigation level at 1.2 ETc (I3) followed by I2and I1. It was found lowest under irrigation level at 0.8 ETc with micro sprinkler irrigation. Amongst the irrigation levels, treatment I3 (1.2 ETc) was found to be significantly superior over treatment I2 (1.0 ETc) and I1 (0.8 ETc) in respect growth and yield of cluster bean. Gross returns and benefit cost ratio were higher in I3 followed by I2 and I1. Nitrogen treatments also significantly influenced the growth and yield parameters. Nitrogen level T3 (30 Kg/ha) recorded significantly highest growth and yield parameters followed by T2 (25 Kg/ha) and T1 (20 Kg/ha). Gross returns and benefit cost ratio were highest in treatment T3 followed by T2 and T1. The total irrigation water applied highest in treatment I3 followed by I2 and I1. Irrigation level at I3 recorded highest water use efficiency.
