Abstract Lentil (Lens culinaris) fertilization significantly influences growth, yield, and nutrient uptake. While phosphorus (P) promotes root development, zinc (Zn) is essential for reproductive processes. A field trial was conducted during the 2017–2018 growing season to investigate the combined effect of P and Zn application. The experiment used a factorial randomized complete block design, with treatments comprising three P and three Zn levels (0%, 50%, and 100% of the recommended doses) and six lentil genotypes (Masoor-2006, Chakwal Masoor, NIA Masoor-2005, Mansehra-89, Masoor-85, and Markaz-09). Among the treatments, the T6 (50% Zn + 100% P) showed the most promising results, increasing grain yield by 42%, 1000-grain weight by 37%, and the number of pods by 45% compared to the control (T1). NIA Masoor-2005 exhibited the highest efficiency in yield and nutrient uptake, followed by Markaz-09. This study recommends the combined application of 100% P and 50% Zn of the recommended doses can enhance lentil productivity and nutrient uptake, supporting sustainable agricultural practices.
