A study was undertaken in solution culture to investigate the performance of two wheat cultivars LU-26S and Pak-81 grown under different salinities (ECe O. 7.5 and 15 dSml ) and varying levels of N (0. 50. 100 and 150 kg ha'). The results showed that LU-26S at ECe 15 dSm I performed better than Pak-81. Of the different N levels used. application of 100 kg N ha' proved to be the most " suitable one. This was attributed to a significant increase in tillering, spike length. lOO-grain weight and grain yield per plant. However. at the highest levels of salinity (15 dSm,l) and N application (150 kg ha t tillering, grain weight and grain yield decreased significantly. Key words: nitrogen application. response of wheat, saline conditions
