Abstract: To evaluate the effect of foliar application of boron on yield and yield components of wheat, the present experiment was conducted at Birsa Agricultural University, Ranchi during winter seasons of 2012-13 and 2013-14. Treatments included four levels of B (T1: 0 kg ha⁻¹, T2: 1 kg ha⁻¹ and T3: 1.5 kg ha⁻¹ B added to the soil and T4: 1kg B ha^-1 as soil along with foliar spray at pre flowering and panicle initiation stage) in a randomized block design. The results of this study showed that each incremental levels of B application contributed towards significantly higher yield and yield attributing character over the control and sterility percentage decreased significantly with the levels of B applications. The highest grain yield was obtained in T4 treatment (3.88 t ha^-1) followed by T3 (3.77 t ha^-1) and T2 (3.53 t ha^-1) and least was recorded in T1 (3.25 t ha^-1). Maximum sterility percentage was found in T1 (19.9%) whereas minimum was recorded in T4 (9.8%). It can be concluded that the application of B @ 1 kg ha⁻¹followed by foliar application of boron is helpful in enhancing the productivity of wheat by reducing the sterility percentage.
