Abstract

A field experiment was conducted during rabi season 2002-03 at research farm of C.S. Azad University of Agriculture and Technology, Kanpur, U.P. with the objective to study the effect of irrigation and nitrogen levels on growth, yield and nitrogen uptake by barley. The experiment was laid out in split plot design with three replications with treatments, comprising four levels of irrigation viz., I1= no irrigation, I2= one irrigation at tillering stage, I3= one irrigation at flag leaf stage and I4= two irrigations each at tillering and flag leaf stage in main plots and four nitrogen levels viz., N1= Control, N2= 30 kg ha-1, N3= 60 kg ha-1 and N4= 90 kg ha-1 in sub-plots. Results revealed that application of two irrigations first at tillering and second at flag leaf stage along with 90 kg nitrogen per hectare gives highest grain yield, straw yield, nitrogen content and nitrogen uptake by grain, straw and protein content as compared to other irrigations (no irrigation, one irrigation at tillering stage, one irrigation at flag leaf stage) and nitrogen treatments (0, 30 and 60 kg ha-1).
