The field experiment was conducted at the Agronomy farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from November 2016 to May, 2017 to response of boro rice for the foliar spray of zinc and boron. Treatment were T1= Recommended Fertilizer (RF), T2= RF+ Foliar spray (FS) with water at tiller initiation (TI), T3= RF + Foliar spray (FS) with water at flowering initiation (FI), T4= Zn (0.2%) FS at TI + RF, T5=Zn (0.5%) FS at TI + RF, T6=Zn (0.8%) FS at TI + RF, T7= Zn (0.2%) FS at FI + RF, T8=Zn (0.5%) FS at FI + RF, T9= Zn (0.8%) FS at FI + RF, T10= B (0.5%) FS at TI + RF, T11= B (1.5%) FS at TI + RF, T12= B (2.0%) FS at TI + RF, T13= B (0.5%) FS at FI + RF, T14= B (1.5%) FS at FI + RF, T15= B (2.0%) FS at FI + RF. The experiment was laid out in a Randomized complete Block Design (RCBD) with three replications. Data on different growth, yield and yield contributing parameters were recorded. The highest plant height and LAI was obtained from T11 where the lowest was found from T1. The highest number of effective and tillers hill-1 (15.13), panicle length (27.86) and filled grains panicle-1 (155.52),  maximum days to panicle initiation, days to flowering and days to maturity (79.67, 117.67 and 152.67 days) was obtained from T11 and the lowest was found from  T1. The highest grain yield, straw yield, biological yield and harvest Index (7.10 t ha-1, 7.61 t ha-1, 14.71 t ha-1 and 48.26) was obtained from  T11.  T11 (B (1.5%) FS at TI + RF) is the superior combination compared to other treatment combinations for rice production.
