An experiment was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from January to April 2004 to study the effect of different levels of nitrogen and boron on the yield of wheat cv. Kanchan. The treatments included four levels of nitrogen VIZ., 45, 60, 85 and 110 kg N ha-1 and four levels of boron viz., 0, 1, 2 and 3 kg B ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. The results revealed that Yield and yield contributing characters were influenced significantly by both levels of nitrogen and boron. Among the levels of nitrogen, 110 kg N ha-1 produced the highest grain (5.54 t ha-1) and straw (8.21 t ha -1) yields. The lowest grain (3.23 t ha-1) and straw (5.52 t ha-1) yields were observed with the application of 45 kg N ha-1. The highest grain (4.95 t ha-1) and straw (7.38 t ha 1) yields were produced With 3 kg B ha-1. The minimum grain (3.59 t ha-1) and straw (6.14 t ha-1) yields were found in the control treatment. Highest plant height (103.23cm) and grains spike-1 (62.53) was observed due to interaction of 110 kg N ha-l and 3 kg B ha-1.
