A field trial was conducted to examine the "Investigating the Impact of Nitrogen, Zinc, and Iron Application on Rice Growth and Yield Characteristics" In the Agriculture Research Farm at Hardoi of Rama University, Mandhana, Kanpur, the current experiment was carried out from Kharif season 2022–23. The experiment followed a Randomized Block Design with nine treatment combinations and three replications. 100% RDN + ZnSO4 15 kg/ha + 5 kg/ha + Nano Urea 3 ml/L, 100% RDN + ZnSO4 20 kg/ha + 10 kg/ha + Nano Urea 3 ml/L, 100% RDN + ZnSO4 25 kg/ha + 15 kg/ha + Nano Urea 3 ml/L, 75% RDN + ZnSO4 15 kg/ha + 5 kg/ha + Nano Urea 3 ml/L, 75% RDN + ZnSO4 20 kg/ha + 10 kg/ha + Nano Urea 3 ml/L , 75% RDN + ZnSO4 25 kg/ha + 15 kg/ha + Nano Urea 3 ml/L , 50% RDN + ZnSO4 15 kg/ha + 5 kg/ha + Nano Urea 3 ml/L, 50% RDN + ZnSO4 20 kg/ha + 10 kg/ha + Nano Urea 3 ml/L , 50% RDN + ZnSO4 25 kg/ha + 15 kg/ha + Nano Urea 3 ml/L, , along with a control (120-60-60 NPK kg/ha). Among the various treatment combinations, the most significant results were observed in T3 (100% RDN + ZnSO4 25 kg/ha + 15 kg/ha + Nano Urea 3 ml/L).
