Field experiment was carried out at the field of Department of Agronomy, BSMRAU campus, Gazipur, of Bangladesh during aman season (July-October) of 2017 to study the effect of zinc fertilizer application on growth, yield and zinc partitioning in three rice varieties: (BRRI dhan 56, BRRI dhan 57 and BRRI dhan 62) at three levels of zinc fertilization, no application of zinc, 10and 20 kg Zn ha-1. The highest leaf area indices of 3.15 in BRRI dhan 56, and 3.27 in BRRI dhan 57 were recorded with the application of 10 kg Zn ha-1 at 75 DAT and 3.28 in BRRI dhan 62 with 20 kg Zn ha-1. Through the growth period the SPAD value was the maximum at 10 kg Zn ha-1 in BRRI dhan 56 and BRRI dhan 57 and in BRRI dhan 62 at 20 kg Zn ha-1. The highest CGR, RGR, NAR were recorded at 10 kg Zn ha-1 in BRRI dhan 56 and BRRI dhan 57, and at 20 kg ha-1 in BRRI dhan 62.Zinc fertilizer at 10 kg Zn ha-1significantly increased the number of effective tiller m-2, length of panicle, total number of spikelet’s panicle-1,1000-grain weight, number of filled spikelet’s panicle-1, grain yield and straw yield in BRRI dhan 56 and BRRI dhan 57, and at 20 kg Zn ha-1 in BRRI dhan 62. It was revealed that the rice varieties BRRI dhan 56 and BRRI dhan 57 responded to the application of 10 kg Zn ha-1, while BRRI dhan 62 to 20 kg Zn ha-1.Overall results indicates, application of zinc might be necessary to ensure satisfactory yield.
