A 2-year field investigation was conducted on sandy-loam soils of Gurdaspur, to study the influence of nitrogen application on yield and grain mottling incidence on varieties of durum (Tritcum dunrm Desf.) wheat. Significant increase in grain and straw yields and reduction in grain mottling were observed with application of nitrogen up to 120 and 160 kglha, respectively, though increasing trend of grain yield continued up to 160 kg N/ha in both the years. Differences among different varieties for growth, yield attributes (except 1,000-grain weight), grain and straw yields were also significant. Varieties PDW 245 and PDW 251 gave the highest grain yield with 160 kg Wha which was on a par with that of PBW 34 and WH 91 2 at the same level of nitrogen. The lowest grain mottling incidence was also recorded in PDW 251 when it received 160 kg M a . Grain mottling incidence in PDW 233 and Raj 6513 was also low at 160 kg Wha.References
