Abstract

A study was undertaken at the Directorate of Wheat Research experimental station, Karnal, India, to evaluate the effect of nitrogen (30, 60 and 90 kg/ha) and irrigation (one, two and three) on yield and grain quality traits of two and six row type malt barley genotypes. The mean grain yield significantly increased from 41.9 to 45.8 q/ha with increase in nitrogen dose from 30 to 90 kg/ha and 41.8 to 45.9 q/ha with increase in irrigations from one to three. The two and six row barleys had almost similar yield potential at higher nitrogen application and irrigation frequency but the six-row type had advantage at lower nitrogen and irrigation. Varietal effects were significant for all the traits, while N significantly affected only grain yield, spikes per unit area, 1000-grain weight and husk content. Irrigation effects were significant for bulk density, grain yield, spikes per unit area, and grains per spike. Traits like grain bulk density, proportion of bold and thin grains and husk content are mainly affected by variety and less affected by management practices.
