Field studies were carried out to investigate the effect of differentnitrogen and sulphur applications on growth parameters, yield andquality parameters of two row malt barley varieties conducted atresearch farm, Rajasthan Agricultural Research Institute, Durgapurafor two consecutive rabi seasons 2015-16 and 2016-17 on loamy sandsoil. The twenty seven treatment combinations consisting of 3 varieties(RD 2849, DWRUB 52 and RD 2668), 3 nitrogen levels (60 kg, 90 kgand 120 kg) and 3 sulphur levels (0 kg, 10 kg and 20 kg) were testedin factorial randomized block design with three replications. Theresults indicated that variety RD 2849 proved significantly superior toDWRUB 52 and RD 2668 with respect to yield (grain and straw yield(q ha-1)) and quality parameters (Bold and Thin grain (%), Hectoliterweight (kg hl-1). In case of nitrogen and sulphur applications,chlorophyll content (%) at flag leaf stage and flag leaf area (cm), grainand straw yield (q ha-1), Nitrogen and Sulphur content (%) in grainand straw and bold and thin grain (%) and hectoliter weight (kg hl-1) of barley were improved. The highest chlorophyll content (%) atflag leaf stage and flag leaf area (cm), grain and straw yield (kg hl-1),Nitrogen and Sulphur content (%) in grain and straw and bold, thingrain (%) and hectoliter weight (kg hl-1) of barley obtained with 120kg N ha-1 and 20 kg S ha-1 and it was found statically at par with 90kg N ha-1 and 10 kg S ha-1 application.DOI.10.25174/2582-2675/2020/85266
