Response of malt barley (Hordeum vulgare L.) varieties to nitrogen and sulphur application under Agro-climatic zone IIIa (semi-arid eastern plain zone) of Rajasthan

Abstract

Field studies were carried out to investigate the effect of different
nitrogen and sulphur applications on growth parameters, yield and
quality parameters of two row malt barley varieties 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 RD 2668), 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 yield (grain and straw yield
(q ha-1)) and quality parameters (Bold and Thin grain (%), Hectoliter
weight (kg hl-1). In case of nitrogen and sulphur applications,
chlorophyll content (%) at flag leaf stage and flag leaf area (cm), grain
and straw yield (q ha-1), Nitrogen and Sulphur content (%) in grain
and straw and bold and thin grain (%) and hectoliter weight (kg hl-
1) of barley were improved. The highest chlorophyll content (%) at
flag leaf stage and flag leaf area (cm), grain and straw yield (kg hl-1),
Nitrogen and Sulphur content (%) in grain and straw and bold, thin
grain (%) and hectoliter weight (kg hl-1) of barley obtained with 120
kg N ha-1 and 20 kg S ha-1 and it was found statically at par with 90
kg N ha-1 and 10 kg S ha-1 application.
