Abstract: The field experiment was conducted at the Center of Excellence for Citrus, College of Agriculture, Nagpur, during the academic year 2022–23. The experiment was laid out in a randomized block design with nine treatments, replicated three times. The data in respect of growth parameters of Jambheri rootstock, that is seedling length (48.68 cm), seedling diameter (0.73 cm), root length (14.56 cm), root diameter (0.87 cm), root volume (15.53 cm³), root dry weight (1.89 g), leaf area (19.88 cm²), number of leaves per seedling (60.44), fresh weight of seedling (36.43 g), and dry weight of seedling (12.14 g), were recorded significantly highest in treatment T₆-Nano DAP (200 ppm), while significantly maximum root-to-shoot ratio (0.301) was found in treatment T₅-Nano DAP (150 ppm) and T₉ treatment shows the minimum result across all treatments. Foliar application of Nano DAP 200 ppm shows promises for healthy growth and optimal cell sap condition in Jambheri rootstock during primary nursery stage.
