Chickpea, an important food legume, is primarily grown on marginal soils with low soil fertility. Although chickpea can fix N, soil phosphorus (P) deficiency in crop growing areas is a major limiting factor for chickpea production. This study was undertaken to evaluate twenty-five chickpea cultivars for morpho-physiological traits and yield under low and normal phosphorous conditions. Based on morpho-physiological traits such as length and area of roots and shoots, root length density, root and shoot biomass, chlorophyll content, number of nodules and root tips, tolerance indices and yield, these cultivars were characterised into susceptible (ICC67, ICC1915, ICC2593, ICC5337, ICC5879, ICC8950, ICC13441, ICC1483, ICC15606 and ICC15888), tolerant (ICC10755, IG72070, ICCV97105, ICCV2, ICCV92809, ICCV92337 and ICCV95423) and the remaining cultivars were moderately tolerant to phosphorous-deficit conditions. Higher activities of enzymes of phosphorous metabolism such as acid phosphatase and phytase in roots and nodules of tolerant chickpea cultivars (ICCV97105, ICCV92337, ICCV95423) as compared to susceptible cultivars (ICC67, ICC15606, ICC15888) at different developmental stages might be attributing to their better performance for growth parameters and productivity traits under phosphorous-deficit conditions.

鹰嘴豆是一种重要的食用豆类，主要生长在土壤肥力低的边缘土壤上。尽管鹰嘴豆可以固氮，但作物种植区的土壤磷 (P) 缺乏是鹰嘴豆生产的主要限制因素。本研究旨在评估 25 个鹰嘴豆品种在低磷和正常磷条件下的形态生理特征和产量。根据形态生理性状，如根茎长度和面积、根长密度、根茎生物量、叶绿素含量、根瘤和根尖数、耐受指数和产量，将这些品种定性为感病品种（ICC67、ICC1915 , ICC2593, ICC5337, ICC5879, ICC8950, ICC13441, ICC1483, ICC15606 和 ICC15888), 耐受 (ICC10755, IG72070, ICCV97105, ICCV2, ICCV92809, ICCV92337 和 ICCV95423) 和其余品种对磷缺乏条件具有中等耐受性。与不同发育阶段的易感品种（ICC67、ICC15606、ICC15888）相比，耐性鹰嘴豆品种（ICCV97105、ICCV92337、ICCV95423）的根和根瘤中磷代谢酶（如酸性磷酸酶和植酸酶）的活性更高，这可能是由于它们更好磷缺乏条件下生长参数和生产力性状的表现。
