Effect of levels of irrigation and nitrogen on growth, yield and nitrogen uptake in barley

Afield experiment was conducted during rabi season at research farm of CS 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 designwiththreereplicationswithtreatments,comprisingfourlevelsofirrigation viz., I= no irrigation, I= one 12irrigation at tillering stage, I= one irrigation 3at flag leaf stage and I= two irrigations each 4at tillering and flag leaf stage in main plots and four nitrogen levels viz., N= Control, 1-1-1-N= 30 kg ha, N= 60 kg haand N= 90 kg ha2341insub-plots.Resultsrevealedthatapplication 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 -1treatments (0, 30 and 60 kg ha)
