Objective of the studies was to evaluate agronomic response of chickpea varieties to phosphorus fertilizers rates and row spacing under irrigation condition. The study was done using split plot design spacing as a main plot, and fertilizer and variety as a subplot, where three row spacing (20cm, 30cm and 40cm) was assigned to the main plot while the factorial combination four triple super phosphate (0kg/ha, 50kg/ha,100kg/ha and 150kg/superphosphate) and representative of Kabuli and Desi type chickpea released varieties such as Arerti and Mariye respectively were assigned to the sub plot. Main effect of inter row spacing did not show significant difference on many studied agronomic parameters. Similarly, main effect of phosphorus fertilizer rates and varieties did not reveal a significant difference for the studied parameters. However, significant differences were obtained on phenology, yield components, and yield for the varieties. Phosphorus (TSP) fertilizer rates utilized in Tselemti District under irrigation did not show differences in most of studied traits. Reasonable row spacing of 20 cm for both types of chickpea could be used for the studied area under irrigation condition.
