Description A f ield exper ime nt was conducted during winte r (rabi) season of 2011-2012 at Researc h Farm
of Agronomy , CCS Hary ana Agricultural University , Hisar, to study the effect of row spacing and
moisture regimes o n bar ley (Hordeum vulgare L.) cultivars planted on raised beds. The experime nt was
laid out in split plot design with three replications keeping three cultivars viz ., BH 393, BH 902 and BH
885 and two rows spacing viz , 2 rows per bed and 3 rows per bed (70 cm wide with 40 cm top and 30
cm furrow) in main plots and three moisture regimes ( irrigation at IW/CPE 0.3, 0.4 & 0.5) in sub plots.
There was signif icant var iatio n among cultivars in respect of growth. Growth parameters were
maximum in BH 902 as compared to rest of the cultivars. The y ield attributes as productive tille rs and
1000-grain weight were signif icantly super ior in BH 902, but grains pe r spike and spike length were
highe r in BH 393. The cultivars BH 902 proved signif icantly super ior in terms of grain, straw and
biol ogical y ield as compared to BH 393 and BH 885. The dif ference was also signif icant between BH
393 and BH 885. The protein conte nt was also recorded highest in BH 902, whe reas, lowest in BH 885.
But hectolite r weight was highest in BH 885 and lowest in BH 393. The highest total wate r
productivity , net return and benef it cost ratio was attained in BH 902 cultivar .
Dry matte r accumulatio n, number of tillers and leaf area was highe r in 3 rows as compared to
2 rows per bed. The most of yield attr ibutes were not af fected signif icantly by row spacing. Among
row spacing, 3 rows per bed resulted into signif icantly highe r grain, straw and biological y ield as
compared to 2 rows per bed. The better grain, straw and biological y ield in 3 rows per bed resulted due
to signif icant inc rease in productive tille rs/m
2
. Quality of barley was not af fected signif icantly by row
spacing. The highe r water productivity , net return and benef it cost ratio was attained in 3 rows per bed.
There was signif icant var iation due to moisture regimes in respect of growth and y i eld
attributes. I rr igation at IW/CPE 0.5 resulted into signif icantly highe r growth and y ield attr ibutes than
irr igation at IW/CPE 0.3, but statistically similar to irr igation at IW/CPE 0.4. I rrigatio n at IW/CPE 0.5
proved signif icantly super ior in terms of grain, straw and biological y ield as compared to irr igation at
IW/CPE 0.3 but at par with irr igation at IW/CPE 0.4. The protein conte nt was recorded highest in
irr igation at IW/CPE 0.3. But hectolite r weight was highest in irr igation at IW/CPE 0.5. The highest
total water productivity , net return and benef it cost ratio was attained with irr igation at IW/CPE 0.5
followed by IW/CPE 0.4 and 0.3. Amo ng the interactio ns between all three factors, grain y ield was
attained maximum with BH 902 cultivar planted in 3 rows per bed and irrigatio n at IW/CPE 0.4.
