To investigate the impact of zinc fertilization on the growth indices of several wheat cultivars growing in the Eastern Indo-Gangatic Plains, a field experiment was conducted in Varanasi, Uttar Pradesh, during the rabi season of 2017–18. Under randomized block design (factorial), seven wheat varieties (HUW 234,V1; HUW 510,V2; HUW 468,V3; HD 2967,V4; PBW 343,V5; PBW 373,V6; and PBW 154,V7) and two zinc levels (0 kg Zn ha-1,Z0 and 5 kg Zn ha-1,Z1) were used in the experiment. The data analysis showed that the highest amount of dry matter (DM) had accumulated in PBW 154. Z1 exhibited the maximum DM accumulation at harvest. At 90 DAS, HD 2967 had the maximum leaf area index (LAI), and treatment with 5 kg Zn ha-1 significantly increased LAI. HUW 234 recorded highest crop growth rate (CGR) between 60 and 90 days interval. Between 60 and 90 DAS the highest CGR value was measured for Z1. Between 60 and 90 DAS, PBW 343 appeared to have the highest relative growth rate (RGR).
