The interactive effect of water stress and nitrogen on yield and biomass of wheat varieties Inqalab "91" and Parwaz "94" were investigated. The objective of present study is to evaluate the compensating role of nitrogen fertilizer in relation to drought stress on the growth and yield of these wheat varieties. Urea as nitrogen fertilizer was applied before imposition of water stress in plots and water stress was imposed 25, 35 and 45 days after germination. The data reveal that sporadic stress and urea fertilizer have highly significant response. The effects of water stress were mostly reduced to greater extent at high nitrogen level (98 gm/plot). Nitrogen applied at higher rates had effectively balanced the adverse effects of water stress.
