Effect Of Boron On The Growth And Yield Of Modern Wheat Varieties In Barind Area

Abstract
A field experiment was carried out at the Agronomy Field Laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi during November 2016 to March 2017, to study the effect of boron (B) on the growth and yield of wheat varieties in Barind area, Bangladesh. The experiment included four modern varieties of wheat viz. BARI Gom 27, BARI Gom 28, BARI Gom 29 and BARI Gom 30 and four levels of boron viz. 0, 0.5, 1.0 and 1.5 kg B ha-1 which were applied as basal dose. All growth parameters were influenced more or less due to boron. Among them, B3 treatment (1.5 kg B ha-1) showed highest TDM and CGR with a few exceptions. Among the varieties, BARI Gom 30 gave the highest TDM and CGR. Variety had significant influence on all the yield and yield contributing characters like tillers plant-1 (no), effective tillers plant-1 (no), grains spike-1 (no), 1000-grain weight (g) and grain yield (t ha-1) and straw yield (t ha-1). BARI Gom 30 produced maximum grain yield (3.479 t ha-1) and BARI Gom 27 gave the minimum grain yield (2.954 t ha-1) among the varieties. The highest grain yield was observed when the field was fertilized with 1.5kg B ha-1 and the lowest was found in control. Key words - Wheat, Variety, Boron, Growth and Yield
