Abstract:
Field studies were carried out to investigate the effect of different nitrogen and sulphur applications on growth, yield and quality parameters of two row malt barley conducted at research farm, Rajasthan Agricultural Research Institute, Durgapura for two consecutive rabi seasons 2015-16 and 2016-17 on loamy sand soil. The twenty-seven treatment combinations consisting of 3 varieties (RD 2849, DWRUB 52 and RD2668), 3 nitrogen levels (60 kg, 90 kg and 120 kg) and 3 sulphur levels (0 kg, 10 kg and 20 kg) were tested in factorial randomized block design with three replications. The results indicated that variety RD 2849 proved significantly superior to DWRUB 52 and RD 2668 with respect to growth parameters (Plant height, dry matter accumulation), Yield parameters (length of spike, 1000- grain weight) and quality parameters (malt homogeneity and hot water extract). In case of nitrogen and sulphur applications, plant height, dry matter accumulation, number of grains per spike, length of spike, 1000- grain weight, grain and straw yield, malt homogeneity and hot water extract (malt extract) of barley were improved. Significantly higher net returns were obtained with variety RD 2849, application of 120 kg N ha^-1 and 20 kg S ha^-1 independently while significantly higher B:C ratio were obtained with variety RD 2849 (1.83), application of 90 kg N ha^-1 (1.83) and 10 kg S (1.75) independently.
