Effect of foliar application of different nutrient sources on the leaf of Jambheri (Citrus jambhiri L.) seedlings

A field experiment was conducted at the Centre of Excellence for Citrus, College of Agriculture, Nagpur during 2022-23 to evaluate the effect of foliar application of different nutrient sources on Jambheri seedlings (Citrus jambhiri L.) at primary and secondary nursery stages. The study aimed to assess the impact of foliar nutrition on seedling growth and identify the most effective nutrient source. The experiment followed a randomized block design (RBD) for the primary nursery and a completely randomized design (CRD) for the secondary nursery, with nine treatments replicated three times. The results showed that foliar application of Nano DAP (200 ppm) (T₆) significantly increased leaf N, P, and K concentrations in both nursery stages, while the control (T₉) recorded the lowest values. Thus, Nano DAP (200 ppm) is recommended for enhancing seedling growth and improving budding survival in Jambheri rootstock seedlings.
