dc.description.abstract A pot experiment was conducted to study genotypes variation for P Uptake and utilization efficiency in four barley genotypes (Tramilo, Rahan, B12-3 and M97( to P applied at adequate and deficient levels (0 and 100 ppm P resp). Phosphorus level and variety interaction was significant for almost all the parameters studied. Substantial differences were observed among genotypes for accumulation of shoot and root dry weight , total biomass and relative reduction in shoot biomass due to phosphorus stress. Phosphorus stress factor ranged between 27.7% to 43.1% that is 2 folds differences in relative reduction in shoot dry weight due phosphorus stress factor among genotypes. Phosphorus utilization efficiency was almost doubled in the genotypes that were grown with no phosphorus supply compared to these grown with 100 ppm P supply. P concentration and uptake in genotypes were significantly different at deficient and adequate phosphorus levels. en_US
