Online Published on 20 February, 2024. Abstract A Field experiment was conducted at S.D.Agricultural University, Sardarkrushinagar, to study the response of chickpea to irrigation and nitrogen levels during rabi season of 2021-22 on loamy sand soil of North Gujarat. Grain and straw yield of chickpea increased significantly with at each higher level of irrigation scheduling up to 0.8 IW/CPE ratio with water application of 450 mm along with 100% RDN (20 kg/ha). Highest nitrogen content in seed and NPK uptake was recorded with 1.0 IW/CPE ratio which was at par with 0.8 IW/CPE ratio. Similarly, 125% RDN recorded at highest nitrogen content and NPK uptake which was at par with 100% RDN. Interaction effect between irrigation scheduling and nitrogen levels on seed yield and total nitrogen uptake by chickpea crop was highly significant. The highest field water use efficiency of chickpea with 0.6 IW/CPE ratio. Applied water with seed yield and field water use efficiency followed quadratic function with regression coefficient (R2) of 0.99. Similarly, regression coefficient of applied water with NPK uptake (0.946, 0.973, 0.982) and applied nitrogen with NPKuptake (0.904, 0.974, 0.960) were highly significant and reflected close relationship between them.
